I'd like a button that creates an image of banana sushi every time I press it. Each image should be different. There should be a toggle next to the button that enables strawberry mode, in which the images are of strawberry sushi instead.
Instead of one huge textfield, it would be nice to have forms for bug-reports, feature-requests, ...
Great benefits with automatic labeling, assigning and other functionalitys not available in that form

Copyright (c) 2023 Stability AI
CreativeML Open RAIL++-M License dated July 26, 2023
Section I: PREAMBLE
Multimodal generative models are being widely adopted and used, and
have the potential to transform the way artists, among other
individuals, conceive and benefit from AI or ML technologies as a tool
for content creation.
Notwithstanding the current and potential benefits that these
artifacts can bring to society at large, there are also concerns about
potential misuses of them, either due to their technical limitations
or ethical considerations.
In short, this license strives for both the open and responsible
downstream use of the accompanying model. When it comes to the open
character, we took inspiration from open source permissive licenses
regarding the grant of IP rights. Referring to the downstream
responsible use, we added use-based restrictions not permitting the
use of the model in very specific scenarios, in order for the licensor
to be able to enforce the license in case potential misuses of the
Model may occur. At the same time, we strive to promote open and
responsible research on generative models for art and content
generation.
Even though downstream derivative versions of the model could be
released under different licensing terms, the latter will always have
to include - at minimum - the same use-based restrictions as the ones
in the original license (this license). We believe in the intersection
between open and responsible AI development; thus, this agreement aims
to strike a balance between both in order to enable responsible
open-science in the field of AI.
This CreativeML Open RAIL++-M License governs the use of the model
(and its derivatives) and is informed by the model card associated
with the model.
NOW THEREFORE, You and Licensor agree as follows:
Definitions
"License" means the terms and conditions for use, reproduction, and
Distribution as defined in this document.
"Data" means a collection of information and/or content extracted from
the dataset used with the Model, including to train, pretrain, or
otherwise evaluate the Model. The Data is not licensed under this
License.
"Output" means the results of operating a Model as embodied in
informational content resulting therefrom.
"Model" means any accompanying machine-learning based assemblies
(including checkpoints), consisting of learnt weights, parameters
(including optimizer states), corresponding to the model architecture
as embodied in the Complementary Material, that have been trained or
tuned, in whole or in part on the Data, using the Complementary
Material.
"Derivatives of the Model" means all modifications to the Model, works
based on the Model, or any other model which is created or initialized
by transfer of patterns of the weights, parameters, activations or
output of the Model, to the other model, in order to cause the other
model to perform similarly to the Model, including - but not limited
to - distillation methods entailing the use of intermediate data
representations or methods based on the generation of synthetic data
by the Model for training the other model.
"Complementary Material" means the accompanying source code and
scripts used to define, run, load, benchmark or evaluate the Model,
and used to prepare data for training or evaluation, if any. This
includes any accompanying documentation, tutorials, examples, etc, if
any.
"Distribution" means any transmission, reproduction, publication or
other sharing of the Model or Derivatives of the Model to a third
party, including providing the Model as a hosted service made
available by electronic or other remote means - e.g. API-based or web
access.
"Licensor" means the copyright owner or entity authorized by the
copyright owner that is granting the License, including the persons or
entities that may have rights in the Model and/or distributing the
Model.
"You" (or "Your") means an individual or Legal Entity exercising
permissions granted by this License and/or making use of the Model for
whichever purpose and in any field of use, including usage of the
Model in an end-use application - e.g. chatbot, translator, image
generator.
"Third Parties" means individuals or legal entities that are not under
common control with Licensor or You.
"Contribution" means any work of authorship, including the original
version of the Model and any modifications or additions to that Model
or Derivatives of the Model thereof, that is intentionally submitted
to Licensor for inclusion in the Model by the copyright owner or by an
individual or Legal Entity authorized to submit on behalf of the
copyright owner. For the purposes of this definition, "submitted"
means any form of electronic, verbal, or written communication sent to
the Licensor or its representatives, including but not limited to
communication on electronic mailing lists, source code control
systems, and issue tracking systems that are managed by, or on behalf
of, the Licensor for the purpose of discussing and improving the
Model, but excluding communication that is conspicuously marked or
otherwise designated in writing by the copyright owner as "Not a
Contribution."
"Contributor" means Licensor and any individual or Legal Entity on
behalf of whom a Contribution has been received by Licensor and
subsequently incorporated within the Model.
Section II: INTELLECTUAL PROPERTY RIGHTS
Both copyright and patent grants apply to the Model, Derivatives of
the Model and Complementary Material. The Model and Derivatives of the
Model are subject to additional terms as described in
Section III.
Grant of Copyright License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare, publicly display, publicly
perform, sublicense, and distribute the Complementary Material, the
Model, and Derivatives of the Model.
Grant of Patent License. Subject to the terms and conditions of this
License and where and as applicable, each Contributor hereby grants to
You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
irrevocable (except as stated in this paragraph) patent license to
make, have made, use, offer to sell, sell, import, and otherwise
transfer the Model and the Complementary Material, where such license
applies only to those patent claims licensable by such Contributor
that are necessarily infringed by their Contribution(s) alone or by
combination of their Contribution(s) with the Model to which such
Contribution(s) was submitted. If You institute patent litigation
against any entity (including a cross-claim or counterclaim in a
lawsuit) alleging that the Model and/or Complementary Material or a
Contribution incorporated within the Model and/or Complementary
Material constitutes direct or contributory patent infringement, then
any patent licenses granted to You under this License for the Model
and/or Work shall terminate as of the date such litigation is asserted
or filed.
Section III: CONDITIONS OF USAGE, DISTRIBUTION AND REDISTRIBUTION
Distribution and Redistribution. You may host for Third Party remote
access purposes (e.g. software-as-a-service), reproduce and distribute
copies of the Model or Derivatives of the Model thereof in any medium,
with or without modifications, provided that You meet the following
conditions: Use-based restrictions as referenced in paragraph 5 MUST
be included as an enforceable provision by You in any type of legal
agreement (e.g. a license) governing the use and/or distribution of
the Model or Derivatives of the Model, and You shall give notice to
subsequent users You Distribute to, that the Model or Derivatives of
the Model are subject to paragraph 5. This provision does not apply to
the use of Complementary Material. You must give any Third Party
recipients of the Model or Derivatives of the Model a copy of this
License; You must cause any modified files to carry prominent notices
stating that You changed the files; You must retain all copyright,
patent, trademark, and attribution notices excluding those notices
that do not pertain to any part of the Model, Derivatives of the
Model. You may add Your own copyright statement to Your modifications
and may provide additional or different license terms and conditions -
respecting paragraph 4.a. - for use, reproduction, or Distribution of
Your modifications, or for any such Derivatives of the Model as a
whole, provided Your use, reproduction, and Distribution of the Model
otherwise complies with the conditions stated in this License.
Use-based restrictions. The restrictions set forth in Attachment A are
considered Use-based restrictions. Therefore You cannot use the Model
and the Derivatives of the Model for the specified restricted
uses. You may use the Model subject to this License, including only
for lawful purposes and in accordance with the License. Use may
include creating any content with, finetuning, updating, running,
training, evaluating and/or reparametrizing the Model. You shall
require all of Your users who use the Model or a Derivative of the
Model to comply with the terms of this paragraph (paragraph 5).
The Output You Generate. Except as set forth herein, Licensor claims
no rights in the Output You generate using the Model. You are
accountable for the Output you generate and its subsequent uses. No
use of the output can contravene any provision as stated in the
License.
Section IV: OTHER PROVISIONS
Updates and Runtime Restrictions. To the maximum extent permitted by
law, Licensor reserves the right to restrict (remotely or otherwise)
usage of the Model in violation of this License.
Trademarks and related. Nothing in this License permits You to make
use of Licensors trademarks, trade names, logos or to otherwise
suggest endorsement or misrepresent the relationship between the
parties; and any rights not expressly granted herein are reserved by
the Licensors.
Disclaimer of Warranty. Unless required by applicable law or agreed to
in writing, Licensor provides the Model and the Complementary Material
(and each Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Model, Derivatives of
the Model, and the Complementary Material and assume any risks
associated with Your exercise of permissions under this License.
Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise, unless
required by applicable law (such as deliberate and grossly negligent
acts) or agreed to in writing, shall any Contributor be liable to You
for damages, including any direct, indirect, special, incidental, or
consequential damages of any character arising as a result of this
License or out of the use or inability to use the Model and the
Complementary Material (including but not limited to damages for loss
of goodwill, work stoppage, computer failure or malfunction, or any
and all other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
Accepting Warranty or Additional Liability. While redistributing the
Model, Derivatives of the Model and the Complementary Material
thereof, You may choose to offer, and charge a fee for, acceptance of
support, warranty, indemnity, or other liability obligations and/or
rights consistent with this License. However, in accepting such
obligations, You may act only on Your own behalf and on Your sole
responsibility, not on behalf of any other Contributor, and only if
You agree to indemnify, defend, and hold each Contributor harmless for
any liability incurred by, or claims asserted against, such
Contributor by reason of your accepting any such warranty or
additional liability.
If any provision of this License is held to be invalid, illegal or
unenforceable, the remaining provisions shall be unaffected thereby
and remain valid as if such provision had not been set forth herein.

#### Migration Caveats
The migration script will migrate your invokeai settings and models,
including textual inversion models, LoRAs and merges that you may have
installed previously. However it does **not** migrate the generated
images stored in your 2.3-format outputs directory. To do this, you
need to run an additional step:
1. From a working InvokeAI 3.0 root directory, start the launcher and
enter menu option [8] to open the "developer's console".
2. At the developer's console command line, type the command:
```bash
invokeai-import-images
```
3. This will lead you through the process of confirming the desired
source and destination for the imported images. The images will
appear in the gallery board of your choice, and contain the
original prompt, model name, and other parameters used to generate
the image.

# Contributing
## Welcome to Invoke AI
We're thrilled to have you here and we're excited for you to contribute.
Invoke AI originated as a project built by the community, and that vision carries forward today as we aim to build the best pro-grade tools available. We work together to incorporate the latest in AI/ML research, making these tools available in over 20 languages to artists and creatives around the world as part of our fully permissive OSS project designed for individual users to self-host and use.
Here are some guidelines to help you get started:
# Methods of Contributing to Invoke AI
Anyone who wishes to contribute to InvokeAI, whether features, bug fixes, code cleanup, testing, code reviews, documentation or translation is very much encouraged to do so.
### Technical Prerequisites
## Development
If youd like to help with development, please see our [development guide](contribution_guides/development.md).
Front-end: You'll need a working knowledge of React and TypeScript.
**New Contributors:** If youre unfamiliar with contributing to open source projects, take a look at our [new contributor guide](contribution_guides/newContributorChecklist.md).
Back-end: Depending on the scope of your contribution, you may need to know SQLite, FastAPI, Python, and Socketio. Also, a good majority of the backend logic involved in processing images is built in a modular way using a concept called "Nodes", which are isolated functions that carry out individual, discrete operations. This design allows for easy contributions of novel pipelines and capabilities.
## Nodes
If youd like to add a Node, please see our [nodes contribution guide](../nodes/contributingNodes.md).
### How to Submit Contributions
## Support and Triaging
Helping support other users in [Discord](https://discord.gg/ZmtBAhwWhy) and on Github are valuable forms of contribution that we greatly appreciate.
To start contributing, please follow these steps:
We receive many issues and requests for help from users. We're limited in bandwidth relative to our the user base, so providing answers to questions or helping identify causes of issues is very helpful. By doing this, you enable us to spend time on the highest priority work.
1. Familiarize yourself with our roadmap and open projects to see where your skills and interests align. These documents can serve as a source of inspiration.
2. Open a Pull Request (PR) with a clear description of the feature you're adding or the problem you're solving. Make sure your contribution aligns with the project's vision.
3. Adhere to general best practices. This includes assuming interoperability with other nodes, keeping the scope of your functions as small as possible, and organizing your code according to our architecture documents.
## Documentation
If youd like to help with documentation, please see our [documentation guide](contribution_guides/documentation.md).
### Types of Contributions We're Looking For
## Translation
If you'd like to help with translation, please see our [translation guide](contribution_guides/translation.md).
We welcome all contributions that improve the project. Right now, we're especially looking for:
## Tutorials
Please reach out to @imic or @hipsterusername on [Discord](https://discord.gg/ZmtBAhwWhy) to help create tutorials for InvokeAI.
1. Quality of life (QOL) enhancements on the front-end.
2. New backend capabilities added through nodes.
3. Incorporating additional optimizations from the broader open-source software community.
We hope you enjoy using our software as much as we enjoy creating it, and we hope that some of those of you who are reading this will elect to become part of our contributor community.
### Communication and Decision-making Process
Project maintainers and code owners review PRs to ensure they align with the project's goals. They may provide design or architectural guidance, suggestions on user experience, or provide more significant feedback on the contribution itself. Expect to receive feedback on your submissions, and don't hesitate to ask questions or propose changes.
# Contributors
For more robust discussions, or if you're planning to add capabilities not currently listed on our roadmap, please reach out to us on our Discord server. That way, we can ensure your proposed contribution aligns with the project's direction before you start writing code.
This project is a combined effort of dedicated people from across the world. [Check out the list of all these amazing people](https://invoke-ai.github.io/InvokeAI/other/CONTRIBUTORS/). We thank them for their time, hard work and effort.
### Code of Conduct and Contribution Expectations
# Code of Conduct
The InvokeAI community is a welcoming place, and we want your help in maintaining that. Please review our [Code of Conduct](https://github.com/invoke-ai/InvokeAI/blob/main/CODE_OF_CONDUCT.md) to learn more - it's essential to maintaining a respectful and inclusive environment.
We want everyone in our community to have a positive experience. To facilitate this, we've established a code of conduct and a statement of values that we expect all contributors to adhere to. Please take a moment to review these documents—they're essential to maintaining a respectful and inclusive environment.

### Custom Output Types
Like with custom inputs, sometimes you might find yourself needing custom
outputs that InvokeAI does not provide. We can easily set one up.
Now that you are familiar with Invocations and Inputs, let us use that knowledge
to create an output that has an `image` field, a `color` field and a `string`
field.
- An invocation output is a class that derives from the parent class of
`BaseInvocationOutput`.
- All invocation outputs must use the `@invocation_output` decorator to provide
their unique output type.
- Output fields must use the provided `OutputField` function. This is very
similar to the `InputField` function described earlier - it's a wrapper around
`pydantic`'s `Field()`.
- It is not mandatory but we recommend using names ending with `Output` for
output types.
- It is not mandatory but we highly recommend adding a `docstring` to describe
what your output type is for.
Now that we know the basic rules for creating a new output type, let us go ahead
and make it.
```python
from .baseinvocation import BaseInvocationOutput, OutputField, invocation_output
from .primitives import ImageField, ColorField
@invocation_output('image_color_string_output')
class ImageColorStringOutput(BaseInvocationOutput):
'''Base class for nodes that output a single image'''
image: ImageField = OutputField(description="The image")
color: ColorField = OutputField(description="The color")
text: str = OutputField(description="The string")
```
That's all there is to it.
<!-- TODO: DANGER - we probably do not want people to create their own field types, because this requires a lot of work on the frontend to accomodate.

color: ColorField = Field(default=ColorField(r=0, g=0, b=0, a=0), description='Background color of an image')
```
### Custom Components For Frontend
**Extra Config**
All input fields also take an additional `Config` class that you can use to do
various advanced things like setting required parameters and etc.
Let us do that for our _ColorField_ and enforce all the values because we did
not define any defaults for our fields.
```python
class ColorField(BaseModel):
'''A field that holds the rgba values of a color'''
r: int = Field(ge=0, le=255, description="The red channel")
g: int = Field(ge=0, le=255, description="The green channel")
b: int = Field(ge=0, le=255, description="The blue channel")
a: int = Field(ge=0, le=255, description="The alpha channel")
class Config:
schema_extra = {"required": ["r", "g", "b", "a"]}
```
Now it becomes mandatory for the user to supply all the values required by our
input field.
We will discuss the `Config` class in extra detail later in this guide and how
you can use it to make your Invocations more robust.
## Custom Output Types
Like with custom inputs, sometimes you might find yourself needing custom
outputs that InvokeAI does not provide. We can easily set one up.
Now that you are familiar with Invocations and Inputs, let us use that knowledge
to put together a custom output type for an Invocation that returns _width_,
_height_ and _background_color_ that we need to create a blank image.
- A custom output type is a class that derives from the parent class of
`BaseInvocationOutput`.
- It is not mandatory but we recommend using names ending with `Output` for
output types. So we'll call our class `BlankImageOutput`
- It is not mandatory but we highly recommend adding a `docstring` to describe
what your output type is for.
- Like Invocations, each output type should have a `type` variable that is
**unique**
Now that we know the basic rules for creating a new output type, let us go ahead
and make it.
```python
from typing import Literal
from pydantic import Field
from .baseinvocation import BaseInvocationOutput
class BlankImageOutput(BaseInvocationOutput):
'''Base output type for creating a blank image'''
type: Literal['blank_image_output'] = 'blank_image_output'
# Inputs
width: int = Field(description='Width of blank image')
height: int = Field(description='Height of blank image')
bg_color: ColorField = Field(description='Background color of blank image')
class Config:
schema_extra = {"required": ["type", "width", "height", "bg_color"]}
```
All set. We now have an output type that requires what we need to create a
blank_image. And if you noticed it, we even used the `Config` class to ensure
the fields are required.
## Custom Configuration
As you might have noticed when making inputs and outputs, we used a class called
`Config` from _pydantic_ to further customize them. Because our inputs and
outputs essentially inherit from _pydantic_'s `BaseModel` class, all
[configuration options](https://docs.pydantic.dev/latest/usage/schema/#schema-customization)
that are valid for _pydantic_ classes are also valid for our inputs and outputs.
You can do the same for your Invocations too but InvokeAI makes our life a
little bit easier on that end.
InvokeAI provides a custom configuration class called `InvocationConfig`
particularly for configuring Invocations. This is exactly the same as the raw
`Config` class from _pydantic_ with some extra stuff on top to help faciliate
parsing of the scheme in the frontend UI.
At the current moment, tihs `InvocationConfig` class is further improved with
the following features related the `ui`.
| Config Option | Field Type | Example |
| ------------- | ------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------- |
| type_hints | `Dict[str, Literal["integer", "float", "boolean", "string", "enum", "image", "latents", "model", "control"]]` | `type_hint: "model"` provides type hints related to the model like displaying a list of available models |
| tags | `List[str]` | `tags: ['resize', 'image']` will classify your invocation under the tags of resize and image. |
| title | `str` | `title: 'Resize Image` will rename your to this custom title rather than infer from the name of the Invocation class. |
So let us update your `ResizeInvocation` with some extra configuration and see
how that works.
```python
from typing import Literal, Union
from pydantic import Field
from .baseinvocation import BaseInvocation, InvocationContext, InvocationConfig
from ..models.image import ImageField, ResourceOrigin, ImageCategory
from .image import ImageOutput
class ResizeInvocation(BaseInvocation):
'''Resizes an image'''
type: Literal['resize'] = 'resize'
# Inputs
image: Union[ImageField, None] = Field(description="The input image", default=None)
width: int = Field(default=512, ge=64, le=2048, description="Width of the new image")
height: int = Field(default=512, ge=64, le=2048, description="Height of the new image")
class Config(InvocationConfig):
schema_extra: {
ui: {
tags: ['resize', 'image'],
title: ['My Custom Resize']
}
}
def invoke(self, context: InvocationContext) -> ImageOutput:
# Load the image using InvokeAI's predefined Image Service.
image = context.services.images.get_pil_image(self.image.image_origin, self.image.image_name)
# Resizing the image
# Because we used the above service, we already have a PIL image. So we can simply resize.
resized_image = image.resize((self.width, self.height))
# Preparing the image for output using InvokeAI's predefined Image Service.
output_image = context.services.images.create(
image=resized_image,
image_origin=ResourceOrigin.INTERNAL,
image_category=ImageCategory.GENERAL,
node_id=self.id,
session_id=context.graph_execution_state_id,
is_intermediate=self.is_intermediate,
)
# Returning the Image
return ImageOutput(
image=ImageField(
image_name=output_image.image_name,
image_origin=output_image.image_origin,
),
width=output_image.width,
height=output_image.height,
)
```
We now customized our code to let the frontend know that our Invocation falls
under `resize` and `image` categories. So when the user searches for these
particular words, our Invocation will show up too.
We also set a custom title for our Invocation. So instead of being called
`Resize`, it will be called `My Custom Resize`.
As simple as that.
As time goes by, InvokeAI will further improve and add more customizability for
Invocation configuration. We will have more documentation regarding this at a
later time.

## Creating a new invocation
To create a new invocation, either find the appropriate module file in
`/ldm/invoke/app/invocations` to add your invocation to, or create a new one in
that folder. All invocations in that folder will be discovered and made
available to the CLI and API automatically. Invocations make use of
[typing](https://docs.python.org/3/library/typing.html) and
[pydantic](https://pydantic-docs.helpmanual.io/) for validation and integration
into the CLI and API.
An invocation looks like this:
```py
class UpscaleInvocation(BaseInvocation):
"""Upscales an image."""
# fmt: off
type: Literal["upscale"] = "upscale"
# Inputs
image: Union[ImageField, None] = Field(description="The input image", default=None)
strength: float = Field(default=0.75, gt=0, le=1, description="The strength")
level: Literal[2, 4] = Field(default=2, description="The upscale level")
# fmt: on
# Schema customisation
class Config(InvocationConfig):
schema_extra = {
"ui": {
"tags": ["upscaling", "image"],
},
}
def invoke(self, context: InvocationContext) -> ImageOutput:
image = context.services.images.get_pil_image(
self.image.image_origin, self.image.image_name
)
results = context.services.restoration.upscale_and_reconstruct(
image_list=[[image, 0]],
upscale=(self.level, self.strength),
strength=0.0, # GFPGAN strength
save_original=False,
image_callback=None,
)
# Results are image and seed, unwrap for now
# TODO: can this return multiple results?
image_dto = context.services.images.create(
image=results[0][0],
image_origin=ResourceOrigin.INTERNAL,
image_category=ImageCategory.GENERAL,
node_id=self.id,
session_id=context.graph_execution_state_id,
is_intermediate=self.is_intermediate,
)
return ImageOutput(
image=ImageField(
image_name=image_dto.image_name,
image_origin=image_dto.image_origin,
),
width=image_dto.width,
height=image_dto.height,
)
```
Each portion is important to implement correctly.
### Class definition and type
```py
class UpscaleInvocation(BaseInvocation):
"""Upscales an image."""
type: Literal['upscale'] = 'upscale'
```
All invocations must derive from `BaseInvocation`. They should have a docstring
that declares what they do in a single, short line. They should also have a
`type` with a type hint that's `Literal["command_name"]`, where `command_name`
is what the user will type on the CLI or use in the API to create this
invocation. The `command_name` must be unique. The `type` must be assigned to
the value of the literal in the type hint.
### Inputs
```py
# Inputs
image: Union[ImageField,None] = Field(description="The input image")
strength: float = Field(default=0.75, gt=0, le=1, description="The strength")
level: Literal[2,4] = Field(default=2, description="The upscale level")
```
Inputs consist of three parts: a name, a type hint, and a `Field` with default,
description, and validation information. For example:
| Part | Value | Description |
| --------- | ------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------- |
| Name | `strength` | This field is referred to as `strength` |
| Type Hint | `float` | This field must be of type `float` |
| Field | `Field(default=0.75, gt=0, le=1, description="The strength")` | The default value is `0.75`, the value must be in the range (0,1], and help text will show "The strength" for this field. |
Notice that `image` has type `Union[ImageField,None]`. The `Union` allows this
field to be parsed with `None` as a value, which enables linking to previous
invocations. All fields should either provide a default value or allow `None` as
a value, so that they can be overwritten with a linked output from another
invocation.
The special type `ImageField` is also used here. All images are passed as
`ImageField`, which protects them from pydantic validation errors (since images
only ever come from links).
Finally, note that for all linking, the `type` of the linked fields must match.
If the `name` also matches, then the field can be **automatically linked** to a
previous invocation by name and matching.
### Config
```py
# Schema customisation
class Config(InvocationConfig):
schema_extra = {
"ui": {
"tags": ["upscaling", "image"],
},
}
```
This is an optional configuration for the invocation. It inherits from
pydantic's model `Config` class, and it used primarily to customize the
autogenerated OpenAPI schema.
The UI relies on the OpenAPI schema in two ways:
- An API client & Typescript types are generated from it. This happens at build
time.
- The node editor parses the schema into a template used by the UI to create the
node editor UI. This parsing happens at runtime.
In this example, a `ui` key has been added to the `schema_extra` dict to provide
some tags for the UI, to facilitate filtering nodes.
See the Schema Generation section below for more information.
### Invoke Function
```py
def invoke(self, context: InvocationContext) -> ImageOutput:
image = context.services.images.get_pil_image(
self.image.image_origin, self.image.image_name
)
results = context.services.restoration.upscale_and_reconstruct(
image_list=[[image, 0]],
upscale=(self.level, self.strength),
strength=0.0, # GFPGAN strength
save_original=False,
image_callback=None,
)
# Results are image and seed, unwrap for now
# TODO: can this return multiple results?
image_dto = context.services.images.create(
image=results[0][0],
image_origin=ResourceOrigin.INTERNAL,
image_category=ImageCategory.GENERAL,
node_id=self.id,
session_id=context.graph_execution_state_id,
is_intermediate=self.is_intermediate,
)
return ImageOutput(
image=ImageField(
image_name=image_dto.image_name,
image_origin=image_dto.image_origin,
),
width=image_dto.width,
height=image_dto.height,
)
```
The `invoke` function is the last portion of an invocation. It is provided an
`InvocationContext` which contains services to perform work as well as a
`session_id` for use as needed. It should return a class with output values that
derives from `BaseInvocationOutput`.
Before being called, the invocation will have all of its fields set from
defaults, inputs, and finally links (overriding in that order).
Assume that this invocation may be running simultaneously with other
invocations, may be running on another machine, or in other interesting
scenarios. If you need functionality, please provide it as a service in the
`InvocationServices` class, and make sure it can be overridden.
### Outputs
```py
class ImageOutput(BaseInvocationOutput):
"""Base class for invocations that output an image"""
# fmt: off
type: Literal["image_output"] = "image_output"
image: ImageField = Field(default=None, description="The output image")
width: int = Field(description="The width of the image in pixels")
height: int = Field(description="The height of the image in pixels")
# fmt: on
class Config:
schema_extra = {"required": ["type", "image", "width", "height"]}
```
Output classes look like an invocation class without the invoke method. Prefer
to use an existing output class if available, and prefer to name inputs the same
as outputs when possible, to promote automatic invocation linking.
## Schema Generation
Invocation, output and related classes are used to generate an OpenAPI schema.
### Required Properties
The schema generation treat all properties with default values as optional. This
makes sense internally, but when when using these classes via the generated
schema, we end up with e.g. the `ImageOutput` class having its `image` property
marked as optional.
We know that this property will always be present, so the additional logic
needed to always check if the property exists adds a lot of extraneous cruft.
To fix this, we can leverage `pydantic`'s
[schema customisation](https://docs.pydantic.dev/usage/schema/#schema-customization)
to mark properties that we know will always be present as required.
Here's that `ImageOutput` class, without the needed schema customisation:
```python
class ImageOutput(BaseInvocationOutput):
"""Base class for invocations that output an image"""
# fmt: off
type: Literal["image_output"] = "image_output"
image: ImageField = Field(default=None, description="The output image")
width: int = Field(description="The width of the image in pixels")
height: int = Field(description="The height of the image in pixels")
# fmt: on
```
The OpenAPI schema that results from this `ImageOutput` will have the `type`,
`image`, `width` and `height` properties marked as optional, even though we know
they will always have a value.
```python
class ImageOutput(BaseInvocationOutput):
"""Base class for invocations that output an image"""
# fmt: off
type: Literal["image_output"] = "image_output"
image: ImageField = Field(default=None, description="The output image")
width: int = Field(description="The width of the image in pixels")
height: int = Field(description="The height of the image in pixels")
# fmt: on
# Add schema customization
class Config:
schema_extra = {"required": ["type", "image", "width", "height"]}
```
With the customization in place, the schema will now show these properties as
required, obviating the need for extensive null checks in client code.

Experimenting with changes to the Python source code is a drag if you have to re-start the server —
and re-load those multi-gigabyte models —
after every change.
For a faster development workflow, add the `--dev_reload` flag when starting the server.
The server will watch for changes to all the Python files in the `invokeai` directory and apply those changes to the
running server on the fly.
This will allow you to avoid restarting the server (and reloading models) in most cases, but there are some caveats; see
the [jurigged documentation](https://github.com/breuleux/jurigged#caveats) for details.
## Front End
<!--#TODO: get input from blessedcoolant here, for the moment inserted the frontend README via snippets extension.-->
--8<-- "invokeai/frontend/web/README.md"
## Developing InvokeAI in VSCode
VSCode offers some nice tools:
- python debugger
- automatic `venv` activation
- remote dev (e.g. run InvokeAI on a beefy linux desktop while you type in
comfort on your macbook)
### Setup
You'll need the
[Python](https://marketplace.visualstudio.com/items?itemName=ms-python.python)
and
[Pylance](https://marketplace.visualstudio.com/items?itemName=ms-python.vscode-pylance)
extensions installed first.
It's also really handy to install the `Jupyter` extensions:
- [Jupyter](https://marketplace.visualstudio.com/items?itemName=ms-toolsai.jupyter)
- [Jupyter Cell Tags](https://marketplace.visualstudio.com/items?itemName=ms-toolsai.vscode-jupyter-cell-tags)
- [Jupyter Notebook Renderers](https://marketplace.visualstudio.com/items?itemName=ms-toolsai.jupyter-renderers)
- [Jupyter Slide Show](https://marketplace.visualstudio.com/items?itemName=ms-toolsai.vscode-jupyter-slideshow)
#### InvokeAI workspace
Creating a VSCode workspace for working on InvokeAI is highly recommended. It
can hold InvokeAI-specific settings and configs.
To make a workspace:
- Open the InvokeAI repo dir in VSCode
- `File` > `Save Workspace As` > save it _outside_ the repo
#### Default python interpreter (i.e. automatic virtual environment activation)
- Use command palette to run command
`Preferences: Open Workspace Settings (JSON)`
- Add `python.defaultInterpreterPath` to `settings`, pointing to your `venv`'s
python
Should look something like this:
```jsonc
{
// I like to have all InvokeAI-related folders in my workspace
"folders": [
{
// repo root
"path": "InvokeAI"
},
{
// InvokeAI root dir, where `invokeai.yaml` lives
"path": "/path/to/invokeai_root"
}
],
"settings": {
// Where your InvokeAI `venv`'s python executable lives
"python.defaultInterpreterPath": "/path/to/invokeai_root/.venv/bin/python"
}
}
```
Now when you open the VSCode integrated terminal, or do anything that needs to
run python, it will automatically be in your InvokeAI virtual environment.
Bonus: When you create a Jupyter notebook, when you run it, you'll be prompted
for the python interpreter to run in. This will default to your `venv` python,
and so you'll have access to the same python environment as the InvokeAI app.
This is _super_ handy.
#### Debugging configs with `launch.json`
Debugging configs are managed in a `launch.json` file. Like most VSCode configs,
these can be scoped to a workspace or folder.
Follow the [official guide](https://code.visualstudio.com/docs/python/debugging)
to set up your `launch.json` and try it out.
Now we can create the InvokeAI debugging configs:
```jsonc
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",

"request": "launch",
"program": "scripts/invokeai-web.py",
"args": [
// Your InvokeAI root dir (where `invokeai.yaml` lives)
"--root",
"/path/to/invokeai_root",
// Access the app from anywhere on your local network
"--host",
"0.0.0.0"
],
"justMyCode": true
},
{
// Run the nodes-based CLI
"name": "InvokeAI CLI",
"type": "python",
"request": "launch",
"program": "scripts/invokeai-cli.py",
"justMyCode": true
},
{
// Run tests
"name": "InvokeAI Test",
"type": "python",
"request": "launch",
"module": "pytest",
"args": ["--capture=no"],
"justMyCode": true
},
{
// Run a single test
"name": "InvokeAI Single Test",
"type": "python",
"request": "launch",
"module": "pytest",
"args": [
// Change this to point to the specific test you are working on
"tests/nodes/test_invoker.py"
],
"justMyCode": true
},
{
// This is the default, useful to just run a single file
"name": "Python: File",
"type": "python",
"request": "launch",
"program": "${file}",
"justMyCode": true
}
]
}
```
You'll see these configs in the debugging configs drop down. Running them will
start InvokeAI with attached debugger, in the correct environment, and work just
like the normal app.
Enjoy debugging InvokeAI with ease (not that we have any bugs of course).
#### Remote dev
This is very easy to set up and provides the same very smooth experience as
local development. Environments and debugging, as set up above, just work,
though you'd need to recreate the workspace and debugging configs on the remote.

[official guide](https://code.visualstudio.com/docs/remote/remote-overview) to
get it set up.
Suggest using VSCode's included settings sync so that your remote dev host has
all the same app settings and extensions automagically.
##### One remote dev gotcha
I've found the automatic port forwarding to be very flakey. You can disable it
in `Preferences: Open Remote Settings (ssh: hostname)`. Search for
`remote.autoForwardPorts` and untick the box.
To forward ports very reliably, use SSH on the remote dev client (e.g. your
macbook). Here's how to forward both backend API port (`9090`) and the frontend
live dev server port (`5173`):
```bash
ssh \
-L 9090:localhost:9090 \
-L 5173:localhost:5173 \
user@remote-dev-host
```
The forwarding stops when you close the terminal window, so suggest to do this
_outside_ the VSCode integrated terminal in case you need to restart VSCode for
an extension update or something
Now, on your remote dev client, you can open `localhost:9090` and access the UI,
now served from the remote dev host, just the same as if it was running on the
client.

# Contributing to the Frontend
# InvokeAI Web UI
- [InvokeAI Web UI](https://github.com/invoke-ai/InvokeAI/tree/main/invokeai/frontend/web/docs#invokeai-web-ui)
- [Stack](https://github.com/invoke-ai/InvokeAI/tree/main/invokeai/frontend/web/docs#stack)
- [Contributing](https://github.com/invoke-ai/InvokeAI/tree/main/invokeai/frontend/web/docs#contributing)
- [Dev Environment](https://github.com/invoke-ai/InvokeAI/tree/main/invokeai/frontend/web/docs#dev-environment)
- [Production builds](https://github.com/invoke-ai/InvokeAI/tree/main/invokeai/frontend/web/docs#production-builds)
The UI is a fairly straightforward Typescript React app, with the Unified Canvas being more complex.
Code is located in `invokeai/frontend/web/` for review.
## Stack
State management is Redux via [Redux Toolkit](https://github.com/reduxjs/redux-toolkit). We lean heavily on RTK:
- `createAsyncThunk` for HTTP requests
- `createEntityAdapter` for fetching images and models
- `createListenerMiddleware` for workflows
The API client and associated types are generated from the OpenAPI schema. See API_CLIENT.md.
Communication with server is a mix of HTTP and [socket.io](https://github.com/socketio/socket.io-client) (with a simple socket.io redux middleware to help).
[Chakra-UI](https://github.com/chakra-ui/chakra-ui) & [Mantine](https://github.com/mantinedev/mantine) for components and styling.
[Konva](https://github.com/konvajs/react-konva) for the canvas, but we are pushing the limits of what is feasible with it (and HTML canvas in general). We plan to rebuild it with [PixiJS](https://github.com/pixijs/pixijs) to take advantage of WebGL's improved raster handling.
[Vite](https://vitejs.dev/) for bundling.
Localisation is via [i18next](https://github.com/i18next/react-i18next), but translation happens on our [Weblate](https://hosted.weblate.org/engage/invokeai/) project. Only the English source strings should be changed on this repo.
## Contributing
Thanks for your interest in contributing to the InvokeAI Web UI!
We encourage you to ping @psychedelicious and @blessedcoolant on [Discord](https://discord.gg/ZmtBAhwWhy) if you want to contribute, just to touch base and ensure your work doesn't conflict with anything else going on. The project is very active.
### Dev Environment
**Setup**
1. Install [node](https://nodejs.org/en/download/). You can confirm node is installed with:
```bash
node --version
```
2. Install [yarn classic](https://classic.yarnpkg.com/lang/en/) and confirm it is installed by running this:
```bash
npm install --global yarn
yarn --version
```
From `invokeai/frontend/web/` run `yarn install` to get everything set up.
Start everything in dev mode:
1. Ensure your virtual environment is running
2. Start the dev server: `yarn dev`
3. Start the InvokeAI Nodes backend: `python scripts/invokeai-web.py # run from the repo root`
4. Point your browser to the dev server address e.g. [http://localhost:5173/](http://localhost:5173/)
### VSCode Remote Dev
We've noticed an intermittent issue with the VSCode Remote Dev port forwarding. If you use this feature of VSCode, you may intermittently click the Invoke button and then get nothing until the request times out. Suggest disabling the IDE's port forwarding feature and doing it manually via SSH:
`ssh -L 9090:localhost:9090 -L 5173:localhost:5173 user@host`
### Production builds
For a number of technical and logistical reasons, we need to commit UI build artefacts to the repo.
If you submit a PR, there is a good chance we will ask you to include a separate commit with a build of the app.
To build for production, run `yarn build`.

# Development
## **What do I need to know to help?**
If you are looking to help to with a code contribution, InvokeAI uses several different technologies under the hood: Python (Pydantic, FastAPI, diffusers) and Typescript (React, Redux Toolkit, ChakraUI, Mantine, Konva). Familiarity with StableDiffusion and image generation concepts is helpful, but not essential.
## **Get Started**
To get started, take a look at our [new contributors checklist](newContributorChecklist.md)
Once you're setup, for more information, you can review the documentation specific to your area of interest:
* #### [InvokeAI Architecure](../ARCHITECTURE.md)
* #### [Frontend Documentation](development_guides/contributingToFrontend.md)
* #### [Node Documentation](../INVOCATIONS.md)
* #### [Local Development](../LOCAL_DEVELOPMENT.md)
If you don't feel ready to make a code contribution yet, no problem! You can also help out in other ways, such as [documentation](documentation.md), [translation](translation.md) or helping support other users and triage issues as they're reported in GitHub.
There are two paths to making a development contribution:
1. Choosing an open issue to address. Open issues can be found in the [Issues](https://github.com/invoke-ai/InvokeAI/issues?q=is%3Aissue+is%3Aopen) section of the InvokeAI repository. These are tagged by the issue type (bug, enhancement, etc.) along with the “good first issues” tag denoting if they are suitable for first time contributors.
1. Additional items can be found on our [roadmap](https://github.com/orgs/invoke-ai/projects/7). The roadmap is organized in terms of priority, and contains features of varying size and complexity. If there is an inflight item youd like to help with, reach out to the contributor assigned to the item to see how you can help.
2. Opening a new issue or feature to add. **Please make sure you have searched through existing issues before creating new ones.**
*Regardless of what you choose, please post in the [#dev-chat](https://discord.com/channels/1020123559063990373/1049495067846524939) channel of the Discord before you start development in order to confirm that the issue or feature is aligned with the current direction of the project. We value our contributors time and effort and want to ensure that no ones time is being misspent.*
## Best Practices:
* Keep your pull requests small. Smaller pull requests are more likely to be accepted and merged
* Comments! Commenting your code helps reviewers easily understand your contribution
* Use Python and Typescripts typing systems, and consider using an editor with [LSP](https://microsoft.github.io/language-server-protocol/) support to streamline development
* Make all communications public. This ensure knowledge is shared with the whole community
## **Where can I go for help?**
If you need help, you can ask questions in the [#dev-chat](https://discord.com/channels/1020123559063990373/1049495067846524939) channel of the Discord.
For frontend related work, **@pyschedelicious** is the best person to reach out to.
For backend related work, please reach out to **@blessedcoolant**, **@lstein**, **@StAlKeR7779** or **@pyschedelicious**.
## **What does the Code of Conduct mean for me?**
Our [Code of Conduct](CODE_OF_CONDUCT.md) means that you are responsible for treating everyone on the project with respect and courtesy regardless of their identity. If you are the victim of any inappropriate behavior or comments as described in our Code of Conduct, we are here for you and will do the best to ensure that the abuser is reprimanded appropriately, per our code.

# Documentation
Documentation is an important part of any open source project. It provides a clear and concise way to communicate how the software works, how to use it, and how to troubleshoot issues. Without proper documentation, it can be difficult for users to understand the purpose and functionality of the project.
## Contributing
All documentation is maintained in the InvokeAI GitHub repository. If you come across documentation that is out of date or incorrect, please submit a pull request with the necessary changes.
When updating or creating documentation, please keep in mind InvokeAI is a tool for everyone, not just those who have familiarity with generative art.
## Help & Questions
Please ping @imic1 or @hipsterusername in the [Discord](https://discord.com/channels/1020123559063990373/1049495067846524939) if you have any questions.

## How do I make a contribution?
Never made an open source contribution before? Wondering how contributions work in our project? Here's a quick rundown!
Before starting these steps, ensure you have your local environment [configured for development](../LOCAL_DEVELOPMENT.md).
1. Find a [good first issue](https://github.com/invoke-ai/InvokeAI/contribute) that you are interested in addressing or a feature that you would like to add. Then, reach out to our team in the [#dev-chat](https://discord.com/channels/1020123559063990373/1049495067846524939) channel of the Discord to ensure you are setup for success.
2. Fork the [InvokeAI](https://github.com/invoke-ai/InvokeAI) repository to your GitHub profile. This means that you will have a copy of the repository under **your-GitHub-username/InvokeAI**.
3. Clone the repository to your local machine using:
```bash
git clone https://github.com/your-GitHub-username/InvokeAI.git
```
If you're unfamiliar with using Git through the commandline, [GitHub Desktop](https://desktop.github.com) is a easy-to-use alternative with a UI. You can do all the same steps listed here, but through the interface.
4. Create a new branch for your fix using:
```bash
git checkout -b branch-name-here
```
5. Make the appropriate changes for the issue you are trying to address or the feature that you want to add.
6. Add the file contents of the changed files to the "snapshot" git uses to manage the state of the project, also known as the index:
```bash
git add -A
```
7. Store the contents of the index with a descriptive message.
```bash
git commit -m "Insert a short message of the changes made here"
```
8. Push the changes to the remote repository using
```bash
git push origin branch-name-here
```
9. Submit a pull request to the **main** branch of the InvokeAI repository. If you're not sure how to, [follow this guide](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request)
10. Title the pull request with a short description of the changes made and the issue or bug number associated with your change. For example, you can title an issue like so "Added more log outputting to resolve #1234".
11. In the description of the pull request, explain the changes that you made, any issues you think exist with the pull request you made, and any questions you have for the maintainer. It's OK if your pull request is not perfect (no pull request is), the reviewer will be able to help you fix any problems and improve it!
12. Wait for the pull request to be reviewed by other collaborators.
13. Make changes to the pull request if the reviewer(s) recommend them.
14. Celebrate your success after your pull request is merged!
If youd like to learn more about contributing to Open Source projects, here is a [Getting Started Guide](https://opensource.com/article/19/7/create-pull-request-github).
## Best Practices:
* Keep your pull requests small. Smaller pull requests are more likely to be accepted and merged
* Comments! Commenting your code helps reviewers easily understand your contribution
* Use Python and Typescripts typing systems, and consider using an editor with [LSP](https://microsoft.github.io/language-server-protocol/) support to streamline development

Unlike TI files, LoRAs do not introduce novel vocabulary into the

are applied to generate imagery. LoRAs may be supplied with a
"trigger" word that they have been explicitly trained on, or may
simply apply their effect without being triggered.

title: Configuration
---
# :material-tune-variant: InvokeAI Configuration
## Intro
InvokeAI has numerous runtime settings which can be used to adjust
many aspects of its operations, including the location of files and
directories, memory usage, and performance. These settings can be
viewed and customized in several ways:
1. By editing settings in the `invokeai.yaml` file.
2. By setting environment variables.
3. On the command-line, when InvokeAI is launched.
In addition, the most commonly changed settings are accessible
graphically via the `invokeai-configure` script.
### How the Configuration System Works
When InvokeAI is launched, the very first thing it needs to do is to
find its "root" directory, which contains its configuration files,
installed models, its database of images, and the folder(s) of
generated images themselves. In this document, the root directory will
be referred to as ROOT.
#### Finding the Root Directory
To find its root directory, InvokeAI uses the following recipe:
1. It first looks for the argument `--root <path>` on the command line
it was launched from, and uses the indicated path if present.
2. Next it looks for the environment variable INVOKEAI_ROOT, and uses
the directory path found there if present.
3. If neither of these are present, then InvokeAI looks for the
folder containing the `.venv` Python virtual environment directory for
the currently active environment. This directory is checked for files
expected inside the InvokeAI root before it is used.
4. Finally, InvokeAI looks for a directory in the current user's home
directory named `invokeai`.
#### Reading the InvokeAI Configuration File
Once the root directory has been located, InvokeAI looks for a file
named `ROOT/invokeai.yaml`, and if present reads configuration values
from it. The top of this file looks like this:
```
InvokeAI:
Web Server:
host: localhost
port: 9090
allow_origins: []
allow_credentials: true
allow_methods:
- '*'
allow_headers:
- '*'
Features:
esrgan: true
internet_available: true
log_tokenization: false
patchmatch: true
restore: true
...
```
This lines in this file are used to establish default values for
Invoke's settings. In the above fragment, the Web Server's listening
port is set to 9090 by the `port` setting.
You can edit this file with a text editor such as "Notepad" (do not
use Word or any other word processor). When editing, be careful to
maintain the indentation, and do not add extraneous text, as syntax
errors will prevent InvokeAI from launching. A basic guide to the
format of YAML files can be found
[here](https://circleci.com/blog/what-is-yaml-a-beginner-s-guide/).
You can fix a broken `invokeai.yaml` by deleting it and running the
configuration script again -- option [7] in the launcher, "Re-run the
configure script".
#### Reading Environment Variables
Next InvokeAI looks for defined environment variables in the format
`INVOKEAI_<setting_name>`, for example `INVOKEAI_port`. Environment
variable values take precedence over configuration file variables. On
a Macintosh system, for example, you could change the port that the
web server listens on by setting the environment variable this way:
```
export INVOKEAI_port=8000
invokeai-web
```
Please check out these
[Macintosh](https://phoenixnap.com/kb/set-environment-variable-mac)
and
[Windows](https://phoenixnap.com/kb/windows-set-environment-variable)
guides for setting temporary and permanent environment variables.
#### Reading the Command Line
Lastly, InvokeAI takes settings from the command line, which override
everything else. The command-line settings have the same name as the
corresponding configuration file settings, preceded by a `--`, for
example `--port 8000`.
If you are using the launcher (`invoke.sh` or `invoke.bat`) to launch
InvokeAI, then just pass the command-line arguments to the launcher:
```
invoke.bat --port 8000 --host 0.0.0.0
```
The arguments will be applied when you select the web server option
(and the other options as well).
If, on the other hand, you prefer to launch InvokeAI directly from the
command line, you would first activate the virtual environment (known
as the "developer's console" in the launcher), and run `invokeai-web`:
```
> C:\Users\Fred\invokeai\.venv\scripts\activate
(.venv) > invokeai-web --port 8000 --host 0.0.0.0
```
You can get a listing and brief instructions for each of the
command-line options by giving the `--help` argument:
```
(.venv) > invokeai-web --help
usage: InvokeAI [-h] [--host HOST] [--port PORT] [--allow_origins [ALLOW_ORIGINS ...]] [--allow_credentials | --no-allow_credentials] [--allow_methods [ALLOW_METHODS ...]]

```
## The Configuration Settings
The configuration settings are divided into several distinct
groups in `invokeia.yaml`:
### Web Server
| Setting | Default Value | Description |
|----------|----------------|--------------|
| `host` | `localhost` | Name or IP address of the network interface that the web server will listen on |
| `port` | `9090` | Network port number that the web server will listen on |
| `allow_origins` | `[]` | A list of host names or IP addresses that are allowed to connect to the InvokeAI API in the format `['host1','host2',...]` |
| `allow_credentials | `true` | Require credentials for a foreign host to access the InvokeAI API (don't change this) |
| `allow_methods` | `*` | List of HTTP methods ("GET", "POST") that the web server is allowed to use when accessing the API |
| `allow_headers` | `*` | List of HTTP headers that the web server will accept when accessing the API |
The documentation for InvokeAI's API can be accessed by browsing to the following URL: [http://localhost:9090/docs].
### Features
These configuration settings allow you to enable and disable various InvokeAI features:
| Setting | Default Value | Description |
|----------|----------------|--------------|
| `esrgan` | `true` | Activate the ESRGAN upscaling options|
| `internet_available` | `true` | When a resource is not available locally, try to fetch it via the internet |
| `log_tokenization` | `false` | Before each text2image generation, print a color-coded representation of the prompt to the console; this can help understand why a prompt is not working as expected |
| `patchmatch` | `true` | Activate the "patchmatch" algorithm for improved inpainting |
### Generation
These options tune InvokeAI's memory and performance characteristics.
| Setting | Default Value | Description |
|-----------------------|---------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `sequential_guidance` | `false` | Calculate guidance in serial rather than in parallel, lowering memory requirements at the cost of some performance loss |
| `attention_type` | `auto` | Select the type of attention to use. One of `auto`,`normal`,`xformers`,`sliced`, or `torch-sdp` |
| `attention_slice_size` | `auto` | When "sliced" attention is selected, set the slice size. One of `auto`, `balanced`, `max` or the integers 1-8|
| `force_tiled_decode` | `false` | Force the VAE step to decode in tiles, reducing memory consumption at the cost of performance |
### Device
These options configure the generation execution device.
| Setting | Default Value | Description |
|-----------------------|---------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `device` | `auto` | Preferred execution device. One of `auto`, `cpu`, `cuda`, `cuda:1`, `mps`. `auto` will choose the device depending on the hardware platform and the installed torch capabilities. |
| `precision` | `auto` | Floating point precision. One of `auto`, `float16` or `float32`. `float16` will consume half the memory of `float32` but produce slightly lower-quality images. The `auto` setting will guess the proper precision based on your video card and operating system |
### Paths
These options set the paths of various directories and files used by
InvokeAI. Relative paths are interpreted relative to INVOKEAI_ROOT, so
if INVOKEAI_ROOT is `/home/fred/invokeai` and the path is
`autoimport/main`, then the corresponding directory will be located at
`/home/fred/invokeai/autoimport/main`.
| Setting | Default Value | Description |
|----------|----------------|--------------|
| `autoimport_dir` | `autoimport/main` | At startup time, read and import any main model files found in this directory |
| `lora_dir` | `autoimport/lora` | At startup time, read and import any LoRA/LyCORIS models found in this directory |
| `embedding_dir` | `autoimport/embedding` | At startup time, read and import any textual inversion (embedding) models found in this directory |
| `controlnet_dir` | `autoimport/controlnet` | At startup time, read and import any ControlNet models found in this directory |
| `conf_path` | `configs/models.yaml` | Location of the `models.yaml` model configuration file |
| `models_dir` | `models` | Location of the directory containing models installed by InvokeAI's model manager |
| `legacy_conf_dir` | `configs/stable-diffusion` | Location of the directory containing the .yaml configuration files for legacy checkpoint models |
| `db_dir` | `databases` | Location of the directory containing InvokeAI's image, schema and session database |
| `outdir` | `outputs` | Location of the directory in which the gallery of generated and uploaded images will be stored |
| `use_memory_db` | `false` | Keep database information in memory rather than on disk; this will not preserve image gallery information across restarts |
Note that the autoimport directories will be searched recursively,
allowing you to organize the models into folders and subfolders in any
way you wish. In addition, while we have split up autoimport
directories by the type of model they contain, this isn't
necessary. You can combine different model types in the same folder
and InvokeAI will figure out what they are. So you can easily use just
one autoimport directory by commenting out the unneeded paths:
```
Paths:
autoimport_dir: autoimport
# lora_dir: null
# embedding_dir: null
# controlnet_dir: null
```
### Logging
These settings control the information, warning, and debugging
messages printed to the console log while InvokeAI is running:
| Setting | Default Value | Description |
|----------|----------------|--------------|
| `log_handlers` | `console` | This controls where log messages are sent, and can be a list of one or more destinations. Values include `console`, `file`, `syslog` and `http`. These are described in more detail below |
| `log_format` | `color` | This controls the formatting of the log messages. Values are `plain`, `color`, `legacy` and `syslog` |
| `log_level` | `debug` | This filters messages according to the level of severity and can be one of `debug`, `info`, `warning`, `error` and `critical`. For example, setting to `warning` will display all messages at the warning level or higher, but won't display "debug" or "info" messages |
Several different log handler destinations are available, and multiple destinations are supported by providing a list:
```
log_handlers:
- console
- syslog=localhost
- file=/var/log/invokeai.log
```
* `console` is the default. It prints log messages to the command-line window from which InvokeAI was launched.
* `syslog` is only available on Linux and Macintosh systems. It uses
the operating system's "syslog" facility to write log file entries
locally or to a remote logging machine. `syslog` offers a variety
of configuration options:
```
syslog=/dev/log` - log to the /dev/log device
syslog=localhost` - log to the network logger running on the local machine
syslog=localhost:512` - same as above, but using a non-standard port
syslog=fredserver,facility=LOG_USER,socktype=SOCK_DRAM`
- Log to LAN-connected server "fredserver" using the facility LOG_USER and datagram packets.
```
* `http` can be used to log to a remote web server. The server must be
properly configured to receive and act on log messages. The option
accepts the URL to the web server, and a `method` argument
indicating whether the message should be submitted using the GET or
POST method.
```
http=http://my.server/path/to/logger,method=POST
```
The `log_format` option provides several alternative formats:
* `color` - default format providing time, date and a message, using text colors to distinguish different log severities
* `plain` - same as above, but monochrome text only
* `syslog` - the log level and error message only, allowing the syslog system to attach the time and date
* `legacy` - a format similar to the one used by the legacy 2.3 InvokeAI releases.

With ControlNet, you can get more control over the output of your image generation, providing you with a way to direct the network towards generating images that better fit your desired style or outcome.
### How it works
ControlNet works by analyzing an input image, pre-processing that
image to identify relevant information that can be interpreted by each
specific ControlNet model, and then inserting that control information
into the generation process. This can be used to adjust the style,
composition, or other aspects of the image to better achieve a
specific result.

This can be used to adjust the style, composition, or other aspects of the image to better achieve a specific result.
### Models
InvokeAI provides access to a series of ControlNet models that provide
different effects or styles in your generated images. Currently
InvokeAI only supports "diffuser" style ControlNet models. These are
folders that contain the files `config.json` and/or
`diffusion_pytorch_model.safetensors` and
`diffusion_pytorch_model.fp16.safetensors`. The name of the folder is
the name of the model.
As part of the model installation, ControlNet models can be selected including a variety of pre-trained models that have been added to achieve different effects or styles in your generated images. Further ControlNet models may require additional code functionality to also be incorporated into Invoke's Invocations folder. You should expect to follow any installation instructions for ControlNet models loaded outside the default models provided by Invoke. The default models include:
***InvokeAI does not currently support checkpoint-format
ControlNets. These come in the form of a single file with the
extension `.safetensors`.***
Diffuser-style ControlNet models are available at HuggingFace
(http://huggingface.co) and accessed via their repo IDs (identifiers
in the format "author/modelname"). The easiest way to install them is
to use the InvokeAI model installer application. Use the
`invoke.sh`/`invoke.bat` launcher to select item [5] and then navigate
to the CONTROLNETS section. Select the models you wish to install and
press "APPLY CHANGES". You may also enter additional HuggingFace
repo_ids in the "Additional models" textbox:
![Model Installer -

Command-line users can launch the model installer using the command
`invokeai-model-install`.
_Be aware that some ControlNet models require additional code
functionality in order to work properly, so just installing a
third-party ControlNet model may not have the desired effect._ Please

title: Model Merging
---
InvokeAI provides the ability to merge two or three diffusers-type models into a new merged model. The
resulting model will combine characteristics of the original, and can
be used to teach an old model new tricks.
# :material-image-off: Model Merging
## How to Merge Models
Model Merging can be be done by navigating to the Model Manager and clicking the "Merge Models" tab. From there, you can select the models and settings you want to use to merge th models.
## Settings
* Model Selection: there are three multiple choice fields that
display all the diffusers-style models that InvokeAI knows about.
If you do not see the model you are looking for, then it is probably
a legacy checkpoint model and needs to be converted using the
`invoke` command-line client and its `!optimize` command. You
must select at least two models to merge. The third can be left at
"None" if you desire.
* Alpha: This is the ratio to use when combining models. It ranges
from 0 to 1. The higher the value, the more weight is given to the
2d and (optionally) 3d models. So if you have two models named "A"
and "B", an alpha value of 0.25 will give you a merged model that is
25% A and 75% B.
* Interpolation Method: This is the method used to combine
weights. The options are "weighted_sum" (the default), "sigmoid",
"inv_sigmoid" and "add_difference". Each produces slightly different
results. When three models are in use, only "add_difference" is
available.
* Save Location: The location you want the merged model to be saved in. Default is in the InvokeAI root folder
* Name for merged model: This is the name for the new model. Please
use InvokeAI conventions - only alphanumeric letters and the
characters ".+-".
* Ignore Mismatches / Force: Not all models are compatible with each other. The merge
script will check for compatibility and refuse to merge ones that
are incompatible. Set this checkbox to try merging anyway.
As of version 2.3, InvokeAI comes with a script that allows you to
merge two or three diffusers-type models into a new merged model. The
resulting model will combine characteristics of the original, and can
be used to teach an old model new tricks.
You may run the merge script by starting the invoke launcher
(`invoke.sh` or `invoke.bat`) and choosing the option (4) for _merge

# Nodes Editor (Experimental Beta)
The nodes editor is a blank canvas allowing for the use of individual functions and image transformations to control the image generation workflow. The node processing flow is usually done from left (inputs) to right (outputs), though linearity can become abstracted the more complex the node graph becomes. Nodes inputs and outputs are connected by dragging connectors from node to node.
To better understand how nodes are used, think of how an electric power bar works. It takes in one input (electricity from a wall outlet) and passes it to multiple devices through multiple outputs. Similarly, a node could have multiple inputs and outputs functioning at the same (or different) time, but all node outputs pass information onward like a power bar passes electricity. Not all outputs are compatible with all inputs, however - Each node has different constraints on how it is expecting to input/output information. In general, node outputs are colour-coded to match compatible inputs of other nodes.
## Anatomy of a Node
Individual nodes are made up of the following:
- Inputs: Edge points on the left side of the node window where you connect outputs from other nodes.
- Outputs: Edge points on the right side of the node window where you connect to inputs on other nodes.
- Options: Various options which are either manually configured, or overridden by connecting an output from another node to the input.
## Diffusion Overview
Taking the time to understand the diffusion process will help you to understand how to set up your nodes in the nodes editor.
There are two main spaces Stable Diffusion works in: image space and latent space.
Image space represents images in pixel form that you look at. Latent space represents compressed inputs. Its in latent space that Stable Diffusion processes images. A VAE (Variational Auto Encoder) is responsible for compressing and encoding inputs into latent space, as well as decoding outputs back into image space.
When you generate an image using text-to-image, multiple steps occur in latent space:
1. Random noise is generated at the chosen height and width. The noises characteristics are dictated by the chosen (or not chosen) seed. This noise tensor is passed into latent space. Well call this noise A.
1. Using a models U-Net, a noise predictor examines noise A, and the words tokenized by CLIP from your prompt (conditioning). It generates its own noise tensor to predict what the final image might look like in latent space. Well call this noise B.
1. Noise B is subtracted from noise A in an attempt to create a final latent image indicative of the inputs. This step is repeated for the number of sampler steps chosen.
1. The VAE decodes the final latent image from latent space into image space.
image-to-image is a similar process, with only step 1 being different:
1. The input image is decoded from image space into latent space by the VAE. Noise is then added to the input latent image. Denoising Strength dictates how much noise is added, 0 being none, and 1 being all-encompassing. Well call this noise A. The process is then the same as steps 2-4 in the text-to-image explanation above.
Furthermore, a model provides the CLIP prompt tokenizer, the VAE, and a U-Net (where noise prediction occurs given a prompt and initial noise tensor).
A noise scheduler (eg. DPM++ 2M Karras) schedules the subtraction of noise from the latent image across the sampler steps chosen (step 3 above). Less noise is usually subtracted at higher sampler steps.

## Node Grouping Concepts
There are several node grouping concepts that can be examined with a narrow focus. These (and other) groupings can be pieced together to make up functional graph setups, and are important to understanding how groups of nodes work together as part of a whole. Note that the screenshots below aren't examples of complete functioning node graphs (see Examples).
### Noise
As described, an initial noise tensor is necessary for the latent diffusion process. As a result, all non-image *ToLatents nodes require a noise node input.
<img width="654" alt="groupsnoise" src="https://github.com/ymgenesis/InvokeAI/assets/25252829/2e8d297e-ad55-4d27-bc93-c119dad2a2c5">
### Conditioning
As described, conditioning is necessary for the latent diffusion process, whether empty or not. As a result, all non-image *ToLatents nodes require positive and negative conditioning inputs. Conditioning is reliant on a CLIP tokenizer provided by the Model Loader node.
<img width="1024" alt="groupsconditioning" src="https://github.com/ymgenesis/InvokeAI/assets/25252829/f8f7ad8a-8d9c-418e-b5ad-1437b774b27e">
### Image Space & VAE
The ImageToLatents node doesn't require a noise node input, but requires a VAE input to convert the image from image space into latent space. In reverse, the LatentsToImage node requires a VAE input to convert from latent space back into image space.
<img width="637" alt="groupsimgvae" src="https://github.com/ymgenesis/InvokeAI/assets/25252829/dd99969c-e0a8-4f78-9b17-3ffe179cef9a">
### Defined & Random Seeds
It is common to want to use both the same seed (for continuity) and random seeds (for variance). To define a seed, simply enter it into the 'Seed' field on a noise node. Conversely, the RandomInt node generates a random integer between 'Low' and 'High', and can be used as input to the 'Seed' edge point on a noise node to randomize your seed.
<img width="922" alt="groupsrandseed" src="https://github.com/ymgenesis/InvokeAI/assets/25252829/af55bc20-60f6-438e-aba5-3ec871443710">
### Control
Control means to guide the diffusion process to adhere to a defined input or structure. Control can be provided as input to non-image *ToLatents nodes from ControlNet nodes. ControlNet nodes usually require an image processor which converts an input image for use with ControlNet.
<img width="805" alt="groupscontrol" src="https://github.com/ymgenesis/InvokeAI/assets/25252829/cc9c5de7-23a7-46c8-bbad-1f3609d999a6">
### LoRA
The Lora Loader node lets you load a LoRA (say that ten times fast) and pass it as output to both the Prompt (Compel) and non-image *ToLatents nodes. A model's CLIP tokenizer is passed through the LoRA into Prompt (Compel), where it affects conditioning. A model's U-Net is also passed through the LoRA into a non-image *ToLatents node, where it affects noise prediction.
<img width="993" alt="groupslora" src="https://github.com/ymgenesis/InvokeAI/assets/25252829/630962b0-d914-4505-b3ea-ccae9b0269da">
### Scaling
Use the ImageScale, ScaleLatents, and Upscale nodes to upscale images and/or latent images. The chosen method differs across contexts. However, be aware that latents are already noisy and compressed at their original resolution; scaling an image could produce more detailed results.
<img width="644" alt="groupsallscale" src="https://github.com/ymgenesis/InvokeAI/assets/25252829/99314f05-dd9f-4b6d-b378-31de55346a13">
### Iteration + Multiple Images as Input
Iteration is a common concept in any processing, and means to repeat a process with given input. In nodes, you're able to use the Iterate node to iterate through collections usually gathered by the Collect node. The Iterate node has many potential uses, from processing a collection of images one after another, to varying seeds across multiple image generations and more. This screenshot demonstrates how to collect several images and pass them out one at a time.
<img width="788" alt="groupsiterate" src="https://github.com/ymgenesis/InvokeAI/assets/25252829/4af5ca27-82c9-4018-8c5b-024d3ee0a121">
### Multiple Image Generation + Random Seeds
Multiple image generation in the node editor is done using the RandomRange node. In this case, the 'Size' field represents the number of images to generate. As RandomRange produces a collection of integers, we need to add the Iterate node to iterate through the collection.
To control seeds across generations takes some care. The first row in the screenshot will generate multiple images with different seeds, but using the same RandomRange parameters across invocations will result in the same group of random seeds being used across the images, producing repeatable results. In the second row, adding the RandomInt node as input to RandomRange's 'Seed' edge point will ensure that seeds are varied across all images across invocations, producing varied results.
<img width="1027" alt="groupsmultigenseeding" src="https://github.com/ymgenesis/InvokeAI/assets/25252829/518d1b2b-fed1-416b-a052-ab06552521b3">
## Examples
With our knowledge of node grouping and the diffusion process, lets break down some basic graphs in the nodes editor. Note that a node's options can be overridden by inputs from other nodes. These examples aren't strict rules to follow and only demonstrate some basic configurations.
### Basic text-to-image Node Graph
<img width="875" alt="nodest2i" src="https://github.com/ymgenesis/InvokeAI/assets/25252829/17c67720-c376-4db8-94f0-5e00381a61ee">
- Model Loader: A necessity to generating images (as weve read above). We choose our model from the dropdown. It outputs a U-Net, CLIP tokenizer, and VAE.
- Prompt (Compel): Another necessity. Two prompt nodes are created. One will output positive conditioning (what you want, dog), one will output negative (what you dont want, cat). They both input the CLIP tokenizer that the Model Loader node outputs.
- Noise: Consider this noise A from step one of the text-to-image explanation above. Choose a seed number, width, and height.
- TextToLatents: This node takes many inputs for converting and processing text & noise from image space into latent space, hence the name TextTo**Latents**. In this setup, it inputs positive and negative conditioning from the prompt nodes for processing (step 2 above). It inputs noise from the noise node for processing (steps 2 & 3 above). Lastly, it inputs a U-Net from the Model Loader node for processing (step 2 above). It outputs latents for use in the next LatentsToImage node. Choose number of sampler steps, CFG scale, and scheduler.
- LatentsToImage: This node takes in processed latents from the TextToLatents node, and the models VAE from the Model Loader node which is responsible for decoding latents back into the image space, hence the name LatentsTo**Image**. This node is the last stop, and once the image is decoded, it is saved to the gallery.
### Basic image-to-image Node Graph
<img width="998" alt="nodesi2i" src="https://github.com/ymgenesis/InvokeAI/assets/25252829/3f2c95d5-cee7-4415-9b79-b46ee60a92fe">
- Model Loader: Choose a model from the dropdown.
- Prompt (Compel): Two prompt nodes. One positive (dog), one negative (dog). Same CLIP inputs from the Model Loader node as before.
- ImageToLatents: Upload a source image directly in the node window, via drag'n'drop from the gallery, or passed in as input. The ImageToLatents node inputs the VAE from the Model Loader node to decode the chosen image from image space into latent space, hence the name ImageTo**Latents**. It outputs latents for use in the next LatentsToLatents node. It also outputs the source image's width and height for use in the next Noise node if the final image is to be the same dimensions as the source image.
- Noise: A noise tensor is created with the width and height of the source image, and connected to the next LatentsToLatents node. Notice the width and height fields are overridden by the input from the ImageToLatents width and height outputs.
- LatentsToLatents: The inputs and options are nearly identical to TextToLatents, except that LatentsToLatents also takes latents as an input. Considering our source image is already converted to latents in the last ImageToLatents node, and text + noise are no longer the only inputs to process, we use the LatentsToLatents node.
- LatentsToImage: Like previously, the LatentsToImage node will use the VAE from the Model Loader as input to decode the latents from LatentsToLatents into image space, and save it to the gallery.
### Basic ControlNet Node Graph
<img width="703" alt="nodescontrol" src="https://github.com/ymgenesis/InvokeAI/assets/25252829/b02ded86-ceb4-44a2-9910-e19ad184d471">
- Model Loader
- Prompt (Compel)
- Noise: Width and height of the CannyImageProcessor ControlNet image is passed in to set the dimensions of the noise passed to TextToLatents.
- CannyImageProcessor: The CannyImageProcessor node is used to process the source image being used as a ControlNet. Each ControlNet processor node applies control in different ways, and has some different options to configure. Width and height are passed to noise, as mentioned. The processed ControlNet image is output to the ControlNet node.
- ControlNet: Select the type of control model. In this case, canny is chosen as the CannyImageProcessor was used to generate the ControlNet image. Configure the control node options, and pass the control output to TextToLatents.
- TextToLatents: Similar to the basic text-to-image example, except ControlNet is passed to the control input edge point.
- LatentsToImage

InvokeAI does not apply watermarking to images by default. However,
many computer scientists working in the field of generative AI worry
that a flood of computer-generated imagery will contaminate the image
data sets needed to train future generations of generative models.
InvokeAI offers an optional watermarking mode that writes a small bit
of text, **InvokeAI**, into each image that it generates using an
"invisible" watermarking library that spreads the information
throughout the image in a way that is not perceptible to the human
eye. If you are planning to share your generated images on
internet-accessible services, we encourage you to activate the
invisible watermark mode in order to help preserve the digital image
environment.
The downside of watermarking is that it increases the size of the
image moderately, and has been reported by some individuals to degrade
image quality. Your mileage may vary.
To read the watermark in an image, activate the InvokeAI virtual
environment (called the "developer's console" in the launcher) and run
the command:
```
invisible-watermark -a decode -t bytes -m dwtDct -l 64 /path/to/image.png

generates. However, it does write metadata into the PNG data area,
including the prompt used to generate the image and relevant parameter
settings. These fields can be examined using the `sd-metadata.py`

## **Invisible Watermark**
## **Seamless Tiling**
In keeping with the principles for responsible AI generation, and to
help AI researchers avoid synthetic images contaminating their
training sets, InvokeAI adds an invisible watermark to each of the
final images it generates. The watermark consists of the text
"InvokeAI" and can be viewed using the
[invisible-watermarks](https://github.com/ShieldMnt/invisible-watermark)
tool.
The seamless tiling mode causes generated images to seamlessly tile
with itself creating repetitive wallpaper-like patterns. To use it,
activate the Seamless Tiling option in the Web GUI and then select
whether to tile on the X (horizontal) and/or Y (vertical) axes. Tiling
will then be active for the next set of generations.
Watermarking is controlled using the `invisible-watermark` setting in
`invokeai.yaml`. To turn it off, add the following line under the `Features`

## **Thresholding and Perlin Noise Initialization Options**
Under the Noise section of the Web UI, you will find two options named
Perlin Noise and Noise Threshold. [Perlin
noise](https://en.wikipedia.org/wiki/Perlin_noise) is a type of
structured noise used to simulate terrain and other natural
textures. The slider controls the percentage of perlin noise that will
be mixed into the image at the beginning of generation. Adding a little
perlin noise to a generation will alter the image substantially.
The noise threshold limits the range of the latent values during
sampling and helps combat the oversharpening seem with higher CFG
scale values.

# :material-image-edit: Postprocessing
This sections details the ability to improve faces and upscale images.
## Intro
This extension provides the ability to restore faces and upscale images.
## Face Fixing
As of InvokeAI 3.0, the easiest way to improve faces created during image generation is through the Inpainting functionality of the Unified Canvas. Simply add the image containing the faces that you would like to improve to the canvas, mask the face to be improved and run the invocation. For best results, make sure to use an inpainting specific model; these are usually identified by the "-inpainting" term in the model name.
The default face restoration module is GFPGAN. The default upscale is
Real-ESRGAN. For an alternative face restoration module, see
[CodeFormer Support](#codeformer-support) below.
## Upscaling
As of version 1.14, environment.yaml will install the Real-ESRGAN package into
the standard install location for python packages, and will put GFPGAN into a
subdirectory of "src" in the InvokeAI directory. Upscaling with Real-ESRGAN
should "just work" without further intervention. Simply indicate the desired scale on
the popup in the Web GUI.
**GFPGAN** requires a series of downloadable model files to work. These are
loaded when you run `invokeai-configure`. If GFPAN is failing with an
error, please run the following from the InvokeAI directory:
```bash
invokeai-configure
```
If you do not run this script in advance, the GFPGAN module will attempt to
download the models files the first time you try to perform facial
reconstruction.
### Upscaling
Open the upscaling dialog by clicking on the "expand" icon located
above the image display area in the Web UI:
@ -19,23 +41,82 @@ above the image display area in the Web UI:
![upscale1](../assets/features/upscale-dialog.png)
</figure>
The default upscaling option is Real-ESRGAN x2 Plus, which will scale your image by a factor of two. This means upscaling a 512x512 image will result in a new 1024x1024 image.
There are three different upscaling parameters that you can
adjust. The first is the scale itself, either 2x or 4x.
Other options are the x4 upscalers, which will scale your image by a factor of 4.
The second is the "Denoising Strength." Higher values will smooth out
the image and remove digital chatter, but may lose fine detail at
higher values.
Third, "Upscale Strength" allows you to adjust how the You can set the
scaling stength between `0` and `1.0` to control the intensity of the
scaling. AI upscalers generally tend to smooth out texture details. If
you wish to retain some of those for natural looking results, we
recommend using values between `0.5 to 0.8`.
[This figure](../assets/features/upscaling-montage.png) illustrates
the effects of denoising and strength. The original image was 512x512,
4x scaled to 2048x2048. The "original" version on the upper left was
scaled using simple pixel averaging. The remainder use the ESRGAN
upscaling algorithm at different levels of denoising and strength.
<figure markdown>
![upscaling](../assets/features/upscaling-montage.png){ width=720 }
</figure>
Both denoising and strength default to 0.75.
### Face Restoration
InvokeAI offers alternative two face restoration algorithms,
[GFPGAN](https://github.com/TencentARC/GFPGAN) and
[CodeFormer](https://huggingface.co/spaces/sczhou/CodeFormer). These
algorithms improve the appearance of faces, particularly eyes and
mouths. Issues with faces are less common with the latest set of
Stable Diffusion models than with the original 1.4 release, but the
restoration algorithms can still make a noticeable improvement in
certain cases. You can also apply restoration to old photographs you
upload.
To access face restoration, click the "smiley face" icon in the
toolbar above the InvokeAI image panel. You will be presented with a
dialog that offers a choice between the two algorithm and sliders that
allow you to adjust their parameters. Alternatively, you may open the
left-hand accordion panel labeled "Face Restoration" and have the
restoration algorithm of your choice applied to generated images
automatically.
Like upscaling, there are a number of parameters that adjust the face
restoration output. GFPGAN has a single parameter, `strength`, which
controls how much the algorithm is allowed to adjust the
image. CodeFormer has two parameters, `strength`, and `fidelity`,
which together control the quality of the output image as described in
the [CodeFormer project
page](https://shangchenzhou.com/projects/CodeFormer/). Default values
are 0.75 for both parameters, which achieves a reasonable balance
between changing the image too much and not enough.
[This figure](../assets/features/restoration-montage.png) illustrates
the effects of adjusting GFPGAN and CodeFormer parameters.
<figure markdown>
![upscaling](../assets/features/restoration-montage.png){ width=720 }

!!! note
Real-ESRGAN is memory intensive. In order to avoid crashes and memory overloads
GFPGAN and Real-ESRGAN are both memory intensive. In order to avoid crashes and memory overloads
during the Stable Diffusion process, these effects are applied after Stable Diffusion has completed
its work.
In single image generations, you will see the output right away but when you are using multiple
iterations, the images will first be generated and then upscaled after that
iterations, the images will first be generated and then upscaled and face restored after that
process is complete. While the image generation is taking place, you will still be able to preview
the base images.

you can disable them on the invoke.py command line with the `--no_esrgan` options.

## Quick guided walkthrough of the WebUI's features
While most of the WebUI's features are intuitive, here is a guided walkthrough
through its various components.
![Invoke Web Server - Major Components](../assets/invoke-web-server-1.png){:width="640px"}
The screenshot above shows the Text to Image tab of the WebUI. There are three
main sections:
1. A **control panel** on the left, which contains various settings
for text to image generation. The most important part is the text
field (currently showing `fantasy painting, horned demon`) for
entering the positive text prompt, another text field right below it for an
optional negative text prompt (concepts to exclude), and a _Invoke_ button
to begin the image rendering process.
1. A **control panel** on the left, which contains various settings for text to
image generation. The most important part is the text field (currently
showing `strawberry sushi`) for entering the text prompt, and the camera icon
directly underneath that will render the image. We'll call this the _Invoke_
button from now on.
2. The **current image** section in the middle, which shows a large
format version of the image you are currently working on. A series
of buttons at the top lets you modify and manipulate the image in
various ways.

Camera icon). After a short wait, you'll see a large image of sushi in the
image panel, and a new thumbnail in the gallery on the right.
If you need more room on the screen, you can turn the gallery off
by typing the **g** hotkey. You can turn it back on later by clicking the
image icon that appears in the gallery's place. The list of hotkeys can
be found by clicking on the keyboard icon above the image gallery.
If you need more room on the screen, you can turn the gallery off by
clicking on the **x** to the right of "Your Invocations". You can turn it
back on later by clicking the image icon that appears in the gallery's
place.

The images are written into the directory indicated by the `--outdir` option
provided at script launch time. By default, this is `outputs/img-samples`
under the InvokeAI directory.
2. Generate a bunch of strawberry sushi images by increasing the number of
requested images by adjusting the Images counter just below the Camera
button. As each is generated, it will be added to the gallery. You can
switch the active image by clicking on the gallery thumbnails.
If you'd like to watch the image generation progress, click the hourglass
icon above the main image area. As generation progresses, you'll see
increasingly detailed versions of the ultimate image.
3. Try playing with different settings, including changing the main
model, the image width and height, the Scheduler, the Steps and
the CFG scale.
The _Model_ changes the main model. Thousands of custom models are
now available, which generate a variety of image styles and
subjects. While InvokeAI comes with a few starter models, it is
easy to import new models into the application. See [Installing
Models](../installation/050_INSTALLING_MODELS.md) for more details.

image. To regenerate a previous image, simply use the original image's
seed value. A slider to the right of the _Seed_ field will change the
seed each time an image is generated.

#### Upscaling
#### Variations on a theme
![Invoke Web Server - Upscaling](../assets/upscaling.png){ align=right width=400px }
1. Let's try generating some variations. Select your favorite sushi image from
the gallery to load it. Then select "Use All" from the list of buttons
above. This will load up all the settings used to generate this image,
including its unique seed.
"Upscaling" is the process of increasing the size of an image while
retaining the sharpness. InvokeAI uses an external library called
"ESRGAN" to do this. To invoke upscaling, simply select an image
and press the "expanding arrows" button above it. You can select
between 2X and 4X upscaling, and adjust the upscaling strength,
which has much the same meaning as in facial reconstruction. Try
running this on one of your previously-generated images.
Go down to the Variations section of the Control Panel and set the button to
On. Set Variation Amount to 0.2 to generate a modest number of variations on
the image, and also set the Image counter to `4`. Press the `invoke` button.
This will generate a series of related images. To obtain smaller variations,
just lower the Variation Amount. You may also experiment with changing the
Sampler. Some samplers generate more variability than others. _k_euler_a_ is
particularly creative, while _ddim_ is pretty conservative.
2. For even more variations, experiment with increasing the setting for
_Perlin_. This adds a bit of noise to the image generation process. Note
that values of Perlin noise greater than 0.15 produce poor images for
several of the samplers.
#### Facial reconstruction and upscaling
Stable Diffusion frequently produces mangled faces, particularly when there are
multiple figures in the same scene. Stable Diffusion has particular issues with
generating reallistic eyes. InvokeAI provides the ability to reconstruct faces
using either the GFPGAN or CodeFormer libraries. For more information see
[POSTPROCESS](POSTPROCESS.md).
1. Invoke a prompt that generates a mangled face. A prompt that often gives
this is "portrait of a lawyer, 3/4 shot" (this is not intended as a slur
against lawyers!) Once you have an image that needs some touching up, load
it into the Image panel, and press the button with the face icon
(highlighted in the first screenshot below). A dialog box will appear. Leave
_Strength_ at 0.8 and press \*Restore Faces". If all goes well, the eyes and
other aspects of the face will be improved (see the second screenshot)
![Invoke Web Server - Original Image](../assets/invoke-web-server-3.png)
![Invoke Web Server - Retouched Image](../assets/invoke-web-server-4.png)
The facial reconstruction _Strength_ field adjusts how aggressively the face
library will try to alter the face. It can be as high as 1.0, but be aware
that this often softens the face airbrush style, losing some details. The
default 0.8 is usually sufficient.
2. "Upscaling" is the process of increasing the size of an image while
retaining the sharpness. InvokeAI uses an external library called "ESRGAN"
to do this. To invoke upscaling, simply select an image and press the _HD_
button above it. You can select between 2X and 4X upscaling, and adjust the
upscaling strength, which has much the same meaning as in facial
reconstruction. Try running this on one of your previously-generated images.
3. Finally, you can run facial reconstruction and/or upscaling automatically
after each Invocation. Go to the Advanced Options section of the Control
Panel and turn on _Restore Face_ and/or _Upscale_.

it in the [Unified Canvas](UNIFIED_CANVAS.md). The Unified Canvas
also allows you to extend borders of the image and fill in the
blank areas, a process called outpainting.

rest intact? This is called Inpainting, and a future version of the InvokeAI
web server will provide an interactive painting canvas on which you can
directly draw the areas you wish to Inpaint into. For now, you can achieve
this effect by using an external photoeditor tool to make one or more
regions of the image transparent as described in [INPAINTING.md] and
uploading that.

the parrot will be replaced, leaving the rest of the original image intact:

### Textual Inversion, LoRA and ControlNet
You can do the same from the Text to Image tab by clicking on the picture icon
above the central image panel. The screenshot below shows where the "use as
initial image" icons are located.
InvokeAI supports several different types of model files that
extending the capabilities of the main model by adding artistic
styles, special effects, or subjects. By mixing and matching textual
inversion, LoRA and ControlNet models, you can achieve many
interesting and beautiful effects.
![Invoke Web Server - Use as Image Links](../assets/invoke-web-server-9.png){:width="640px"}
We will give an example using a LoRA model named "Ink Scenery". This
LoRA, which can be downloaded from Civitai (civitai.com), is
specialized to paint landscapes that look like they were made with
dripping india ink. To install this LoRA, we first download it and
put it into the `autoimport/lora` folder located inside the
`invokeai` root directory. After restarting the web server, the
LoRA will now become available for use.
### Unified Canvas
To see this LoRA at work, we'll first generate an image without it
using the standard `stable-diffusion-v1-5` model. Choose this
model and enter the prompt "mountains, ink". Here is a typical
generated image, a mountain range rendered in ink and watercolor
wash:
See the [Unified Canvas Guide](UNIFIED_CANVAS.md)
![Ink Scenery without LoRA](../assets/lora-example-0.png){ width=512px }
## Reference
Now let's install and activate the Ink Scenery LoRA. Go to
https://civitai.com/models/78605/ink-scenery-or and download the LoRA
model file to `invokeai/autoimport/lora` and restart the web
server. (Alternatively, you can use [InvokeAI's Web Model
Manager](../installation/050_INSTALLING_MODELS.md) to download and
install the LoRA directly by typing its URL into the _Import
Models_->_Location_ field).
### Additional Options
Scroll down the control panel until you get to the LoRA accordion
section, and open it:
| parameter <img width=160 align="right"> | effect |
| --------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------ |
| `--web_develop` | Starts the web server in development mode. |
| `--web_verbose` | Enables verbose logging |
| `--cors [CORS ...]` | Additional allowed origins, comma-separated |
| `--host HOST` | Web server: Host or IP to listen on. Set to 0.0.0.0 to accept traffic from other devices on your network. |

### Web Specific Features
Click the popup menu and select "Ink scenery". (If it isn't there, then
the model wasn't installed to the right place, or perhaps you forgot
to restart the web server.) The LoRA section will change to look like this:
The web experience offers an incredibly easy-to-use experience for interacting
with the InvokeAI toolkit. For detailed guidance on individual features, see the
Feature-specific help documents available in this directory. Note that the
latest functionality available in the CLI may not always be available in the Web
interface.
![LoRA Section Loaded](../assets/lora-example-2.png){ width=512px }
#### Dark Mode & Light Mode
Note that there is now a slider control for _Ink scenery_. The slider
controls how much influence the LoRA model will have on the generated
image.
The InvokeAI interface is available in a nano-carbon black & purple Dark Mode,
and a "burn your eyes out Nosferatu" Light Mode. These can be toggled by
clicking the Sun/Moon icons at the top right of the interface.
Run the "mountains, ink" prompt again and observe the change in style:
![InvokeAI Web Server - Dark Mode](../assets/invoke_web_dark.png)
![Ink Scenery](../assets/lora-example-3.png){ width=512px }
![InvokeAI Web Server - Light Mode](../assets/invoke_web_light.png)
Try adjusting the weight slider for larger and smaller weights and
generate the image after each adjustment. The higher the weight, the
more influence the LoRA will have.
#### Invocation Toolbar
To remove the LoRA completely, just click on its trash can icon.
The left side of the InvokeAI interface is available for customizing the prompt
and the settings used for invoking your new image. Typing your prompt into the
open text field and clicking the Invoke button will produce the image based on
the settings configured in the toolbar.
Multiple LoRAs can be added simultaneously and combined with textual
inversions and ControlNet models. Please see [Textual Inversions and
LoRAs](CONCEPTS.md) and [Using ControlNet](CONTROLNET.md) for details.
See below for additional documentation related to each feature:
## Summary

- [Image to Image](./IMG2IMG.md)
- [Other](./OTHER.md)
This walkthrough just skims the surface of the many things InvokeAI
can do. Please see [Features](index.md) for more detailed reference
guides.
#### Invocation Gallery
The currently selected --outdir (or the default outputs folder) will display all
previously generated files on load. As new invocations are generated, these will
be dynamically added to the gallery, and can be previewed by selecting them.
Each image also has a simple set of actions (e.g., Delete, Use Seed, Use All
Parameters, etc.) that can be accessed by hovering over the image.
#### Image Workspace
When an image from the Invocation Gallery is selected, or is generated, the
image will be displayed within the center of the interface. A quickbar of common
image interactions are displayed along the top of the image, including:
- Use image in the `Image to Image` workflow
- Initialize Face Restoration on the selected file
- Initialize Upscaling on the selected file
- View File metadata and details
- Delete the file

Taking the time to understand the diffusion process will help you to understand how to more effectively use InvokeAI.
There are two main ways Stable Diffusion works - with images, and latents.
Image space represents images in pixel form that you look at. Latent space represents compressed inputs. Its in latent space that Stable Diffusion processes images. A VAE (Variational Auto Encoder) is responsible for compressing and encoding inputs into latent space, as well as decoding outputs back into image space.
To fully understand the diffusion process, we need to understand a few more terms: UNet, CLIP, and conditioning.
A U-Net is a model trained on a large number of latent images with with known amounts of random noise added. This means that the U-Net can be given a slightly noisy image and it will predict the pattern of noise needed to subtract from the image in order to recover the original.
CLIP is a model that tokenizes and encodes text into conditioning. This conditioning guides the model during the denoising steps to produce a new image.
The U-Net and CLIP work together during the image generation process at each denoising step, with the U-Net removing noise in such a way that the result is similar to images in the U-Nets training set, while CLIP guides the U-Net towards creating images that are most similar to the prompt.
When you generate an image using text-to-image, multiple steps occur in latent space:
1. Random noise is generated at the chosen height and width. The noises characteristics are dictated by seed. This noise tensor is passed into latent space. Well call this noise A.
2. Using a models U-Net, a noise predictor examines noise A, and the words tokenized by CLIP from your prompt (conditioning). It generates its own noise tensor to predict what the final image might look like in latent space. Well call this noise B.
3. Noise B is subtracted from noise A in an attempt to create a latent image consistent with the prompt. This step is repeated for the number of sampler steps chosen.
4. The VAE decodes the final latent image from latent space into image space.
Image-to-image is a similar process, with only step 1 being different:
1. The input image is encoded from image space into latent space by the VAE. Noise is then added to the input latent image. Denoising Strength dictates how may noise steps are added, and the amount of noise added at each step. A Denoising Strength of 0 means there are 0 steps and no noise added, resulting in an unchanged image, while a Denoising Strength of 1 results in the image being completely replaced with noise and a full set of denoising steps are performance. The process is then the same as steps 2-4 in the text-to-image process.
Furthermore, a model provides the CLIP prompt tokenizer, the VAE, and a U-Net (where noise prediction occurs given a prompt and initial noise tensor).
A noise scheduler (eg. DPM++ 2M Karras) schedules the subtraction of noise from the latent image across the sampler steps chosen (step 3 above). Less noise is usually subtracted at higher sampler steps.

# Getting Started with AI Image Generation
New to image generation with AI? Youre in the right place!
This is a high level walkthrough of some of the concepts and terms youll see as you start using InvokeAI. Please note, this is not an exhaustive guide and may be out of date due to the rapidly changing nature of the space.
## Using InvokeAI
### **Prompt Crafting**
- Prompts are the basis of using InvokeAI, providing the models directions on what to generate. As a general rule of thumb, the more detailed your prompt is, the better your result will be.
*To get started, heres an easy template to use for structuring your prompts:*
- Subject, Style, Quality, Aesthetic
- **Subject:** What your image will be about. E.g. “a futuristic city with trains”, “penguins floating on icebergs”, “friends sharing beers”
- **Style:** The style or medium in which your image will be in. E.g. “photograph”, “pencil sketch”, “oil paints”, or “pop art”, “cubism”, “abstract”
- **Quality:** A particular aspect or trait that you would like to see emphasized in your image. E.g. "award-winning", "featured in {relevant set of high quality works}", "professionally acclaimed". Many people often use "masterpiece".
- **Aesthetics:** The visual impact and design of the artwork. This can be colors, mood, lighting, setting, etc.
- There are two prompt boxes: *Positive Prompt* & *Negative Prompt*.
- A **Positive** Prompt includes words you want the model to reference when creating an image.
- Negative Prompt is for anything you want the model to eliminate when creating an image. It doesnt always interpret things exactly the way you would, but helps control the generation process. Always try to include a few terms - you can typically use lower quality image terms like “blurry” or “distorted” with good success.
- Some examples prompts you can try on your own:
- A detailed oil painting of a tranquil forest at sunset with vibrant+ colors and soft, golden light filtering through the trees
- friends sharing beers in a busy city, realistic colored pencil sketch, twilight, masterpiece, bright, lively
### Generation Workflows
- Invoke offers a number of different workflows for interacting with models to produce images. Each is extremely powerful on its own, but together provide you an unparalleled way of producing high quality creative outputs that align with your vision.
- **Text to Image:** The text to image tab focuses on the key workflow of using a prompt to generate a new image. It includes other features that help control the generation process as well.
- **Image to Image:** With image to image, you provide an image as a reference (called the “initial image”), which provides more guidance around color and structure to the AI as it generates a new image. This is provided alongside the same features as Text to Image.
- **Unified Canvas:** The Unified Canvas is an advanced AI-first image editing tool that is easy to use, but hard to master. Drag an image onto the canvas from your gallery in order to regenerate certain elements, edit content or colors (known as inpainting), or extend the image with an exceptional degree of consistency and clarity (called outpainting).
### Improving Image Quality
- Fine tuning your prompt - the more specific you are, the closer the image will turn out to what is in your head! Adding more details in the Positive Prompt or Negative Prompt can help add / remove pieces of your image to improve it - You can also use advanced techniques like upweighting and downweighting to control the influence of certain words. [Learn more here](https://invoke-ai.github.io/InvokeAI/features/PROMPTS/#prompt-syntax-features).
- **Tip: If youre seeing poor results, try adding the things you dont like about the image to your negative prompt may help. E.g. distorted, low quality, unrealistic, etc.**
- Explore different models - Other models can produce different results due to the data theyve been trained on. Each model has specific language and settings it works best with; a models documentation is your friend here. Play around with some and see what works best for you!
- Increasing Steps - The number of steps used controls how much time the model is given to produce an image, and depends on the “Scheduler” used. The schedule controls how each step is processed by the model. More steps tends to mean better results, but will take longer - We recommend at least 30 steps for most
- Tweak and Iterate - Remember, its best to change one thing at a time so you know what is working and what isn't. Sometimes you just need to try a new image, and other times using a new prompt might be the ticket. For testing, consider turning off the “random” Seed - Using the same seed with the same settings will produce the same image, which makes it the perfect way to learn exactly what your changes are doing.
- Explore Advanced Settings - InvokeAI has a full suite of tools available to allow you complete control over your image creation process - Check out our [docs if you want to learn more](https://invoke-ai.github.io/InvokeAI/features/).
## Terms & Concepts
If you're interested in learning more, check out [this presentation](https://docs.google.com/presentation/d/1IO78i8oEXFTZ5peuHHYkVF-Y3e2M6iM5tCnc-YBfcCM/edit?usp=sharing) from one of our maintainers (@lstein).
### Stable Diffusion
Stable Diffusion is deep learning, text-to-image model that is the foundation of the capabilities found in InvokeAI. Since the release of Stable Diffusion, there have been many subsequent models created based on Stable Diffusion that are designed to generate specific types of images.
### Prompts
Prompts provide the models directions on what to generate. As a general rule of thumb, the more detailed your prompt is, the better your result will be.
### Models
Models are the magic that power InvokeAI. These files represent the output of training a machine on understanding massive amounts of images - providing them with the capability to generate new images using just a text description of what youd like to see. (Like Stable Diffusion!)
Invoke offers a simple way to download several different models upon installation, but many more can be discovered online, including at ****. Each model can produce a unique style of output, based on the images it was trained on - Try out different models to see which best fits your creative vision!
- *Models that contain “inpainting” in the name are designed for use with the inpainting feature of the Unified Canvas*
### Scheduler
Schedulers guide the process of removing noise (de-noising) from data. They determine:
1. The number of steps to take to remove the noise.
2. Whether the steps are random (stochastic) or predictable (deterministic).
3. The specific method (algorithm) used for de-noising.
Experimenting with different schedulers is recommended as each will produce different outputs!
### Steps
The number of de-noising steps each generation through.
Schedulers can be intricate and there's often a balance to strike between how quickly they can de-noise data and how well they can do it. It's typically advised to experiment with different schedulers to see which one gives the best results. There has been a lot written on the internet about different schedulers, as well as exploring what the right level of "steps" are for each. You can save generation time by reducing the number of steps used, but you'll want to make sure that you are satisfied with the quality of images produced!
### Low-Rank Adaptations / LoRAs
Low-Rank Adaptations (LoRAs) are like a smaller, more focused version of models, intended to focus on training a better understanding of how a specific character, style, or concept looks.
### Textual Inversion Embeddings
Textual Inversion Embeddings, like LoRAs, assist with more easily prompting for certain characters, styles, or concepts. However, embeddings are trained to update the relationship between a specific word (known as the “trigger”) and the intended output.
### ControlNet
ControlNets are neural network models that are able to extract key features from an existing image and use these features to guide the output of the image generation model.
### VAE
Variational auto-encoder (VAE) is a encode/decode model that translates the "latents" image produced during the image generation procees to the large pixel images that we see.

## Troubleshooting
### _OSErrors on Windows while installing dependencies_
During a zip file installation or an online update, installation stops
with an error like this:
![broken-dependency-screenshot](../assets/troubleshooting/broken-dependency.png){:width="800px"}
This seems to happen particularly often with the `pydantic` and
`numpy` packages. The most reliable solution requires several manual
steps to complete installation.
Open up a Powershell window and navigate to the `invokeai` directory
created by the installer. Then give the following series of commands:
```cmd
rm .\.venv -r -force
python -mvenv .venv
.\.venv\Scripts\activate
pip install invokeai
invokeai-configure --yes --root .
```
If you see anything marked as an error during this process please stop
and seek help on the Discord [installation support
channel](https://discord.com/channels/1020123559063990373/1041391462190956654). A
few warning messages are OK.
If you are updating from a previous version, this should restore your
system to a working state. If you are installing from scratch, there
is one additional command to give:
```cmd
wget -O invoke.bat https://raw.githubusercontent.com/invoke-ai/InvokeAI/main/installer/templates/invoke.bat.in
```
This will create the `invoke.bat` script needed to launch InvokeAI and
its related programs.
### _Stable Diffusion XL Generation Fails after Trying to Load unet_
InvokeAI is working in other respects, but when trying to generate
images with Stable Diffusion XL you get a "Server Error". The text log
in the launch window contains this log line above several more lines of
error messages:
```INFO --> Loading model:D:\LONG\PATH\TO\MODEL, type sdxl:main:unet```
This failure mode occurs when there is a network glitch during
downloading the very large SDXL model.
To address this, first go to the Web Model Manager and delete the
Stable-Diffusion-XL-base-1.X model. Then navigate to HuggingFace and
manually download the .safetensors version of the model. The 1.0
version is located at
https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/tree/main
and the file is named `sd_xl_base_1.0.safetensors`.
Save this file to disk and then reenter the Model Manager. Navigate to

.safetensors file. Press "Add Model".

* This optimization is intended for the newer version of graphics card (40/30 series) but results have been seen with older graphics card.
### Torch Installation
When installing torch and torchvision manually with `pip`, remember to provide
the argument `--extra-index-url

## Installation
There are two ways to install and manage models:
There are multiple ways to install and manage models:
1. The `invokeai-model-install` script which will download and install
them for you. In addition to supporting main models, you can install
ControlNet, LoRA and Textual Inversion models.
1. The `invokeai-configure` script which will download and install them for you.
2. The web interface (WebUI) has a GUI for importing and managing
2. The command-line tool (CLI) has commands that allows you to import, configure and modify
models files.
3. The web interface (WebUI) has a GUI for importing and managing
models.
3. By placing models (or symbolic links to models) inside one of the
InvokeAI root directory's `autoimport` folder.
### Installation via `invokeai-configure`
### Installation via `invokeai-model-install`
From the `invoke` launcher, choose option (6) "re-run the configure
script to download new models." This will launch the same script that
prompted you to select models at install time. You can use this to add
models that you skipped the first time around. It is all right to
specify a model that was previously downloaded; the script will just
confirm that the files are complete.
From the `invoke` launcher, choose option [5] "Download and install

skipped the first time around. It is all right to specify a model that
was previously downloaded; the script will just confirm that the files
are complete.
### Installation via the CLI
The installer has different panels for installing main models from
HuggingFace, models from Civitai and other arbitrary web sites,
ControlNet models, LoRA/LyCORIS models, and Textual Inversion
embeddings. Each section has a text box in which you can enter a new
model to install. You can refer to a model using its:
You can install a new model, including any of the community-supported ones, via
the command-line client's `!import_model` command.
1. Local path to the .ckpt, .safetensors or diffusers folder on your local machine
2. A directory on your machine that contains multiple models
3. A URL that points to a downloadable model
4. A HuggingFace repo id
#### Installing individual `.ckpt` and `.safetensors` models
Previously-installed models are shown with checkboxes. Uncheck a box
to unregister the model from InvokeAI. Models that are physically
installed inside the InvokeAI root directory will be deleted and
purged (after a confirmation warning). Models that are located outside
the InvokeAI root directory will be unregistered but not deleted.
If the model is already downloaded to your local disk, use
`!import_model /path/to/file.ckpt` to load it. For example:
Note: The installer script uses a console-based text interface that requires
significant amounts of horizontal and vertical space. If the display
looks messed up, just enlarge the terminal window and/or relaunch the
script.
If you wish you can script model addition and deletion, as well as
listing installed models. Start the "developer's console" and give the
command `invokeai-model-install --help`. This will give you a series
of command-line parameters that will let you control model
installation. Examples:
```
# (list all controlnet models)
invokeai-model-install --list controlnet
# (install the model at the indicated URL)
invokeai-model-install --add https://civitai.com/api/download/models/128713
# (delete the named model)
invokeai-model-install --delete sd-1/main/analog-diffusion
```bash
invoke> !import_model C:/Users/fred/Downloads/martians.safetensors
```
### Installation via the Web GUI
!!! tip "Forward Slashes"
On Windows systems, use forward slashes rather than backslashes
in your file paths.
If you do use backslashes,
you must double them like this:
`C:\\Users\\fred\\Downloads\\martians.safetensors`
To install a new model using the Web GUI, do the following:
Alternatively you can directly import the file using its URL:
1. Open the InvokeAI Model Manager (cube at the bottom of the
left-hand panel) and navigate to *Import Models*
```bash
invoke> !import_model https://example.org/sd_models/martians.safetensors
```
2. In the field labeled *Location* type in the path to the model you
wish to install. You may use a URL, HuggingFace repo id, or a path on
your local disk.
For this to work, the URL must not be password-protected. Otherwise
you will receive a 404 error.
3. Alternatively, the *Scan for Models* button allows you to paste in
the path to a folder somewhere on your machine. It will be scanned for
importable models and prompt you to add the ones of your choice.
When you import a legacy model, the CLI will first ask you what type
of model this is. You can indicate whether it is a model based on
Stable Diffusion 1.x (1.4 or 1.5), one based on Stable Diffusion 2.x,
or a 1.x inpainting model. Be careful to indicate the correct model
type, or it will not load correctly. You can correct the model type
after the fact using the `!edit_model` command.
4. Press *Add Model* and wait for confirmation that the model
was added.
The system will then ask you a few other questions about the model,
including what size image it was trained on (usually 512x512), what
name and description you wish to use for it, and whether you would
like to install a custom VAE (variable autoencoder) file for the
model. For recent models, the answer to the VAE question is usually
"no," but it won't hurt to answer "yes".
To delete a model, Select *Model Manager* to list all the currently
installed models. Press the trash can icons to delete any models you
wish to get rid of. Models whose weights are located inside the
InvokeAI `models` directory will be purged from disk, while those
located outside will be unregistered from InvokeAI, but not deleted.
After importing, the model will load. If this is successful, you will
be asked if you want to keep the model loaded in memory to start
generating immediately. You'll also be asked if you wish to make this
the default model on startup. You can change this later using
`!edit_model`.
You can see where model weights are located by clicking on the model name.
This will bring up an editable info panel showing the model's characteristics,
including the `Model Location` of its files.
#### Importing a batch of `.ckpt` and `.safetensors` models from a directory
### Installation via the `autoimport` function
You may also point `!import_model` to a directory containing a set of
`.ckpt` or `.safetensors` files. They will be imported _en masse_.
In the InvokeAI root directory you will find a series of folders under
`autoimport`, one each for main models, controlnets, embeddings and
Loras. Any models that you add to these directories will be scanned
at startup time and registered automatically.
!!! example
You may create symbolic links from these folders to models located
elsewhere on disk and they will be autoimported. You can also create
subfolders and organize them as you wish.
```console
invoke> !import_model C:/Users/fred/Downloads/civitai_models/
```
The location of the autoimport directories are controlled by settings
in `invokeai.yaml`. See [Configuration](../features/CONFIGURATION.md).
You will be given the option to import all models found in the
directory, or select which ones to import. If there are subfolders
within the directory, they will be searched for models to import.
#### Installing `diffusers` models
You can install a `diffusers` model from the HuggingFace site using
`!import_model` and the HuggingFace repo_id for the model:
```bash
invoke> !import_model andite/anything-v4.0
```
Alternatively, you can download the model to disk and import it from
there. The model may be distributed as a ZIP file, or as a Git
repository:
```bash
invoke> !import_model C:/Users/fred/Downloads/andite--anything-v4.0
```
!!! tip "The CLI supports file path autocompletion"
Type a bit of the path name and hit ++tab++ in order to get a choice of
possible completions.
!!! tip "On Windows, you can drag model files onto the command-line"
Once you have typed in `!import_model `, you can drag the
model file or directory onto the command-line to insert the model path. This way, you don't need to
type it or copy/paste. However, you will need to reverse or
double backslashes as noted above.
Before installing, the CLI will ask you for a short name and
description for the model, whether to make this the default model that
is loaded at InvokeAI startup time, and whether to replace its
VAE. Generally the answer to the latter question is "no".
### Converting legacy models into `diffusers`
The CLI `!convert_model` will convert a `.safetensors` or `.ckpt`
models file into `diffusers` and install it.This will enable the model
to load and run faster without loss of image quality.
The usage is identical to `!import_model`. You may point the command
to either a downloaded model file on disk, or to a (non-password
protected) URL:
```bash
invoke> !convert_model C:/Users/fred/Downloads/martians.safetensors
```
After a successful conversion, the CLI will offer you the option of
deleting the original `.ckpt` or `.safetensors` file.
### Optimizing a previously-installed model
Lastly, if you have previously installed a `.ckpt` or `.safetensors`
file and wish to convert it into a `diffusers` model, you can do this
without re-downloading and converting the original file using the
`!optimize_model` command. Simply pass the short name of an existing
installed model:
```bash
invoke> !optimize_model martians-v1.0
```
The model will be converted into `diffusers` format and replace the
previously installed version. You will again be offered the
opportunity to delete the original `.ckpt` or `.safetensors` file.
### Related CLI Commands
There are a whole series of additional model management commands in
the CLI that you can read about in [Command-Line
Interface](../features/CLI.md). These include:
* `!models` - List all installed models
* `!switch <model name>` - Switch to the indicated model
* `!edit_model <model name>` - Edit the indicated model to change its name, description or other properties
* `!del_model <model name>` - Delete the indicated model
### Manually editing `configs/models.yaml`
If you are comfortable with a text editor then you may simply edit `models.yaml`
directly.
You will need to download the desired `.ckpt/.safetensors` file and
place it somewhere on your machine's filesystem. Alternatively, for a
`diffusers` model, record the repo_id or download the whole model
directory. Then using a **text** editor (e.g. the Windows Notepad
application), open the file `configs/models.yaml`, and add a new
stanza that follows this model:
#### A legacy model
A legacy `.ckpt` or `.safetensors` entry will look like this:
```yaml
arabian-nights-1.0:
description: A great fine-tune in Arabian Nights style
weights: ./path/to/arabian-nights-1.0.ckpt
config: ./configs/stable-diffusion/v1-inference.yaml
format: ckpt
width: 512
height: 512
default: false
```
Note that `format` is `ckpt` for both `.ckpt` and `.safetensors` files.
#### A diffusers model
A stanza for a `diffusers` model will look like this for a HuggingFace
model with a repository ID:
```yaml
arabian-nights-1.1:
description: An even better fine-tune of the Arabian Nights
repo_id: captahab/arabian-nights-1.1
format: diffusers
default: true
```
And for a downloaded directory:
```yaml
arabian-nights-1.1:
description: An even better fine-tune of the Arabian Nights
path: /path/to/captahab-arabian-nights-1.1
format: diffusers
default: true
```
There is additional syntax for indicating an external VAE to use with
this model. See `INITIAL_MODELS.yaml` and `models.yaml` for examples.
After you save the modified `models.yaml` file relaunch
`invokeai`. The new model will now be available for your use.
### Installation via the WebUI
To access the WebUI Model Manager, click on the button that looks like
a cube in the upper right side of the browser screen. This will bring
up a dialogue that lists the models you have already installed, and
allows you to load, delete or edit them:
<figure markdown>
![model-manager](../assets/installing-models/webui-models-1.png)
</figure>
To add a new model, click on **+ Add New** and select to either a
checkpoint/safetensors model, or a diffusers model:
<figure markdown>
![model-manager-add-new](../assets/installing-models/webui-models-2.png)
</figure>
In this example, we chose **Add Diffusers**. As shown in the figure
below, a new dialogue prompts you to enter the name to use for the
model, its description, and either the location of the `diffusers`
model on disk, or its Repo ID on the HuggingFace web site. If you
choose to enter a path to disk, the system will autocomplete for you
as you type:
<figure markdown>
![model-manager-add-diffusers](../assets/installing-models/webui-models-3.png)
</figure>
Press **Add Model** at the bottom of the dialogue (scrolled out of
site in the figure), and the model will be downloaded, imported, and
registered in `models.yaml`.
The **Add Checkpoint/Safetensor Model** option is similar, except that
in this case you can choose to scan an entire folder for
checkpoint/safetensors files to import. Simply type in the path of the
directory and press the "Search" icon. This will display the
`.ckpt` and `.safetensors` found inside the directory and its
subfolders, and allow you to choose which ones to import:
<figure markdown>
![model-manager-add-checkpoint](../assets/installing-models/webui-models-4.png)
</figure>
## Model Management Startup Options
The `invoke` launcher and the `invokeai` script accept a series of
command-line arguments that modify InvokeAI's behavior when loading
models. These can be provided on the command line, or added to the
InvokeAI root directory's `invokeai.init` initialization file.
The arguments are:
* `--model <model name>` -- Start up with the indicated model loaded
* `--ckpt_convert` -- When a checkpoint/safetensors model is loaded, convert it into a `diffusers` model in memory. This does not permanently save the converted model to disk.
* `--autoconvert <path/to/directory>` -- Scan the indicated directory path for new checkpoint/safetensors files, convert them into `diffusers` models, and import them into InvokeAI.
Here is an example of providing an argument on the command line using
the `invoke.sh` launch script:
```bash
invoke.sh --autoconvert /home/fred/stable-diffusion-checkpoints
```
And here is what the same argument looks like in `invokeai.init`:
```bash
--outdir="/home/fred/invokeai/outputs
--no-nsfw_checker
--autoconvert /home/fred/stable-diffusion-checkpoints
```

# Overview
We offer several ways to install InvokeAI, each one suited to your
experience and preferences. We suggest that everyone start by
reviewing the
[hardware](010_INSTALL_AUTOMATED.md#hardware_requirements) and
[software](010_INSTALL_AUTOMATED.md#software_requirements)
requirements, as they are the same across each install method. Then
pick the install method most suitable to your level of experience and
needs.
See the [troubleshooting
section](010_INSTALL_AUTOMATED.md#troubleshooting) of the automated
install guide for frequently-encountered installation issues.
This fork is supported across Linux, Windows and Macintosh. Linux users can use
either an Nvidia-based card (with CUDA support) or an AMD card (using the ROCm
driver).
## **[Automated Installer](010_INSTALL_AUTOMATED.md)**
✅ This is the recommended installation method for first-time users.
This is a script that will install all of InvokeAI's essential
third party libraries and InvokeAI itself. It includes access to a
"developer console" which will help us debug problems with you and
give you to access experimental features.
## **[Manual Installation](020_INSTALL_MANUAL.md)**
This method is recommended for experienced users and developers.
In this method you will manually run the commands needed to install
InvokeAI and its dependencies. We offer two recipes: one suited to
those who prefer the `conda` tool, and one suited to those who prefer
`pip` and Python virtual environments. In our hands the pip install
is faster and more reliable, but your mileage may vary.
Note that the conda installation method is currently deprecated and
will not be supported at some point in the future.
## **[Docker Installation](040_INSTALL_DOCKER.md)**
This method is recommended for those familiar with running Docker containers.
We offer a method for creating Docker containers containing InvokeAI and its dependencies. This method is recommended for individuals with experience with Docker containers and understand the pluses and minuses of a container-based install.

title: Overview
---
We offer several ways to install InvokeAI, each one suited to your
experience and preferences. We suggest that everyone start by
reviewing the
[hardware](010_INSTALL_AUTOMATED.md#hardware_requirements) and
[software](010_INSTALL_AUTOMATED.md#software_requirements)
requirements, as they are the same across each install method. Then
pick the install method most suitable to your level of experience and
needs.
See the [troubleshooting
section](010_INSTALL_AUTOMATED.md#troubleshooting) of the automated
install guide for frequently-encountered installation issues.
## Main Application
1. [Automated Installer](010_INSTALL_AUTOMATED.md)
This is a script that will install all of InvokeAI's essential
third party libraries and InvokeAI itself. It includes access to a
"developer console" which will help us debug problems with you and
give you to access experimental features.
2. [Manual Installation](020_INSTALL_MANUAL.md)
In this method you will manually run the commands needed to install
InvokeAI and its dependencies. We offer two recipes: one suited to
those who prefer the `conda` tool, and one suited to those who prefer
`pip` and Python virtual environments. In our hands the pip install
is faster and more reliable, but your mileage may vary.
Note that the conda installation method is currently deprecated and
will not be supported at some point in the future.
This method is recommended for users who have previously used `conda`
or `pip` in the past, developers, and anyone who wishes to remain on
the cutting edge of future InvokeAI development and is willing to put
up with occasional glitches and breakage.
3. [Docker Installation](040_INSTALL_DOCKER.md)
We also offer a method for creating Docker containers containing
InvokeAI and its dependencies. This method is recommended for
individuals with experience with Docker containers and understand
the pluses and minuses of a container-based install.

# Using the Workflow Editor
The workflow editor is a blank canvas allowing for the use of individual functions and image transformations to control the image generation workflow. Nodes take in inputs on the left side of the node, and return an output on the right side of the node. A node graph is composed of multiple nodes that are connected together to create a workflow. Nodes' inputs and outputs are connected by dragging connectors from node to node. Inputs and outputs are color coded for ease of use.
If you're not familiar with Diffusion, take a look at our [Diffusion Overview.](../help/diffusion.md) Understanding how diffusion works will enable you to more easily use the Workflow Editor and build workflows to suit your needs.
## UI Features
### Linear View
The Workflow Editor allows you to create a UI for your workflow, to make it easier to iterate on your generations.
To add an input to the Linear UI, right click on the input and select "Add to Linear View".
The Linear UI View will also be part of the saved workflow, allowing you share workflows and enable other to use them, regardless of complexity.
![linearview](../assets/nodes/linearview.png)
### Renaming Fields and Nodes
Any node or input field can be renamed in the workflow editor. If the input field you have renamed has been added to the Linear View, the changed name will be reflected in the Linear View and the node.
### Managing Nodes
* Ctrl+C to copy a node
* Ctrl+V to paste a node
* Backspace/Delete to delete a node
* Shift+Click to drag and select multiple nodes
## Important Concepts
There are several node grouping concepts that can be examined with a narrow focus. These (and other) groupings can be pieced together to make up functional graph setups, and are important to understanding how groups of nodes work together as part of a whole. Note that the screenshots below aren't examples of complete functioning node graphs (see Examples).
### Noise
An initial noise tensor is necessary for the latent diffusion process. As a result, the Denoising node requires a noise node input.
![groupsnoise](../assets/nodes/groupsnoise.png)
### Text Prompt Conditioning
Conditioning is necessary for the latent diffusion process, whether empty or not. As a result, the Denoising node requires positive and negative conditioning inputs. Conditioning is reliant on a CLIP text encoder provided by the Model Loader node.
![groupsconditioning](../assets/nodes/groupsconditioning.png)
### Image to Latents & VAE
The ImageToLatents node takes in a pixel image and a VAE and outputs a latents. The LatentsToImage node does the opposite, taking in a latents and a VAE and outpus a pixel image.
![groupsimgvae](../assets/nodes/groupsimgvae.png)
### Defined & Random Seeds
It is common to want to use both the same seed (for continuity) and random seeds (for variety). To define a seed, simply enter it into the 'Seed' field on a noise node. Conversely, the RandomInt node generates a random integer between 'Low' and 'High', and can be used as input to the 'Seed' edge point on a noise node to randomize your seed.
![groupsrandseed](../assets/nodes/groupsrandseed.png)
### ControlNet
The ControlNet node outputs a Control, which can be provided as input to a Denoise Latents node. Depending on the type of ControlNet desired, ControlNet nodes usually require an image processor node, such as a Canny Processor or Depth Processor, which prepares an input image for use with ControlNet.
![groupscontrol](../assets/nodes/groupscontrol.png)
### LoRA
The Lora Loader node lets you load a LoRA and pass it as output.A LoRA provides fine-tunes to the UNet and text encoder weights that augment the base models image and text vocabularies.
![groupslora](../assets/nodes/groupslora.png)
### Scaling
Use the ImageScale, ScaleLatents, and Upscale nodes to upscale images and/or latent images. Upscaling is the process of enlarging an image and adding more detail. The chosen method differs across contexts. However, be aware that latents are already noisy and compressed at their original resolution; scaling an image could produce more detailed results.
![groupsallscale](../assets/nodes/groupsallscale.png)
### Iteration + Multiple Images as Input
Iteration is a common concept in any processing, and means to repeat a process with given input. In nodes, you're able to use the Iterate node to iterate through collections usually gathered by the Collect node. The Iterate node has many potential uses, from processing a collection of images one after another, to varying seeds across multiple image generations and more. This screenshot demonstrates how to collect several images and use them in an image generation workflow.
![groupsiterate](../assets/nodes/groupsiterate.png)
### Batch / Multiple Image Generation + Random Seeds
Batch or multiple image generation in the workflow editor is done using the RandomRange node. In this case, the 'Size' field represents the number of images to generate, meaning this example will generate 4 images. As RandomRange produces a collection of integers, we need to add the Iterate node to iterate through the collection. This noise can then be fed to the Denoise Latents node for it to iterate through the denoising process with the different seeds provided.

# ComfyUI to InvokeAI
If you're coming to InvokeAI from ComfyUI, welcome! You'll find things are similar but different - the good news is that you already know how things should work, and it's just a matter of wiring them up!
Some things to note:
- InvokeAI's nodes tend to be more granular than default nodes in Comfy. This means each node in Invoke will do a specific task and you might need to use multiple nodes to achieve the same result. The added granularity improves the control you have have over your workflows.
- InvokeAI's backend and ComfyUI's backend are very different which means Comfy workflows are not able to be imported into InvokeAI. However, we have created a [list of popular workflows](exampleWorkflows.md) for you to get started with Nodes in InvokeAI!

# Community Nodes
These are nodes that have been developed by the community, for the community. If you're not sure what a node is, you can learn more about nodes [here](overview.md).
If you'd like to submit a node for the community, please refer to the [node creation overview](contributingNodes.md).
To download a node, simply download the `.py` node file from the link and add it to the `invokeai/app/invocations` folder in your Invoke AI install location. If you used the automated installation, this can be found inside the `.venv` folder. Along with the node, an example node graph should be provided to help you get started with the node.
To use a community workflow, download the the `.json` node graph file and load it into Invoke AI via the **Load Workflow** button in the Workflow Editor.
## Community Nodes
### FaceTools
**Description:** FaceTools is a collection of nodes created to manipulate faces as you would in Unified Canvas. It includes FaceMask, FaceOff, and FacePlace. FaceMask autodetects a face in the image using MediaPipe and creates a mask from it. FaceOff similarly detects a face, then takes the face off of the image by adding a square bounding box around it and cropping/scaling it. FacePlace puts the bounded face image from FaceOff back onto the original image. Using these nodes with other inpainting node(s), you can put new faces on existing things, put new things around existing faces, and work closer with a face as a bounded image. Additionally, you can supply X and Y offset values to scale/change the shape of the mask for finer control on FaceMask and FaceOff. See GitHub repository below for usage examples.
**Node Link:** https://github.com/ymgenesis/FaceTools/
**FaceMask Output Examples**

--------------------------------
### Oobabooga
**Description:** asks a local LLM running in Oobabooga's Text-Generation-Webui to write a prompt based on the user input.
**Link:** https://github.com/sammyf/oobabooga-node
**Example:**
"describe a new mystical creature in its natural environment"
*can return*
"The mystical creature I am describing to you is called the "Glimmerwing". It is a majestic, iridescent being that inhabits the depths of the most enchanted forests and glimmering lakes. Its body is covered in shimmering scales that reflect every color of the rainbow, and it has delicate, translucent wings that sparkle like diamonds in the sunlight. The Glimmerwing's home is a crystal-clear lake, surrounded by towering trees with leaves that shimmer like jewels. In this serene environment, the Glimmerwing spends its days swimming gracefully through the water, chasing schools of glittering fish and playing with the gentle ripples of the lake's surface.
As the sun sets, the Glimmerwing perches on a branch of one of the trees, spreading its wings to catch the last rays of light. The creature's scales glow softly, casting a rainbow of colors across the forest floor. The Glimmerwing sings a haunting melody, its voice echoing through the stillness of the night air. Its song is said to have the power to heal the sick and bring peace to troubled souls. Those who are lucky enough to hear the Glimmerwing's song are forever changed by its beauty and grace."
![glimmerwing_small](https://github.com/sammyf/oobabooga-node/assets/42468608/cecdd820-93dd-4c35-abbf-607e001fb2ed)
**Requirement**
a Text-Generation-Webui instance (might work remotely too, but I never tried it) and obviously InvokeAI 3.x
**Note**
This node works best with SDXL models, especially as the style can be described independantly of the LLM's output.
--------------------------------
### Depth Map from Wavefront OBJ
**Description:** Render depth maps from Wavefront .obj files (triangulated) using this simple 3D renderer utilizing numpy and matplotlib to compute and color the scene. There are simple parameters to change the FOV, camera position, and model orientation.
To be imported, an .obj must use triangulated meshes, so make sure to enable that option if exporting from a 3D modeling program. This renderer makes each triangle a solid color based on its average depth, so it will cause anomalies if your .obj has large triangles. In Blender, the Remesh modifier can be helpful to subdivide a mesh into small pieces that work well given these limitations.
**Node Link:** https://github.com/dwringer/depth-from-obj-node
**Example Usage:**
![depth from obj usage graph](https://raw.githubusercontent.com/dwringer/depth-from-obj-node/main/depth_from_obj_usage.jpg)
--------------------------------
### Enhance Image (simple adjustments)
**Description:** Boost or reduce color saturation, contrast, brightness, sharpness, or invert colors of any image at any stage with this simple wrapper for pillow [PIL]'s ImageEnhance module.
Color inversion is toggled with a simple switch, while each of the four enhancer modes are activated by entering a value other than 1 in each corresponding input field. Values less than 1 will reduce the corresponding property, while values greater than 1 will enhance it.
**Node Link:** https://github.com/dwringer/image-enhance-node
**Example Usage:**
![enhance image usage graph](https://raw.githubusercontent.com/dwringer/image-enhance-node/main/image_enhance_usage.jpg)
--------------------------------
### Generative Grammar-Based Prompt Nodes
**Description:** This set of 3 nodes generates prompts from simple user-defined grammar rules (loaded from custom files - examples provided below). The prompts are made by recursively expanding a special template string, replacing nonterminal "parts-of-speech" until no more nonterminal terms remain in the string.
This includes 3 Nodes:
- *Lookup Table from File* - loads a YAML file "prompt" section (or of a whole folder of YAML's) into a JSON-ified dictionary (Lookups output)
- *Lookups Entry from Prompt* - places a single entry in a new Lookups output under the specified heading
- *Prompt from Lookup Table* - uses a Collection of Lookups as grammar rules from which to randomly generate prompts.
**Node Link:** https://github.com/dwringer/generative-grammar-prompt-nodes
**Example Usage:**
![lookups usage example graph](https://raw.githubusercontent.com/dwringer/generative-grammar-prompt-nodes/main/lookuptables_usage.jpg)
--------------------------------
### Image and Mask Composition Pack
**Description:** This is a pack of nodes for composing masks and images, including a simple text mask creator and both image and latent offset nodes. The offsets wrap around, so these can be used in conjunction with the Seamless node to progressively generate centered on different parts of the seamless tiling.
This includes 4 Nodes:
- *Text Mask (simple 2D)* - create and position a white on black (or black on white) line of text using any font locally available to Invoke.
- *Image Compositor* - Take a subject from an image with a flat backdrop and layer it on another image using a chroma key or flood select background removal.
- *Offset Latents* - Offset a latents tensor in the vertical and/or horizontal dimensions, wrapping it around.
- *Offset Image* - Offset an image in the vertical and/or horizontal dimensions, wrapping it around.
**Node Link:** https://github.com/dwringer/composition-nodes
**Example Usage:**
![composition nodes usage graph](https://raw.githubusercontent.com/dwringer/composition-nodes/main/composition_nodes_usage.jpg)
--------------------------------
### Size Stepper Nodes
**Description:** This is a set of nodes for calculating the necessary size increments for doing upscaling workflows. Use the *Final Size & Orientation* node to enter your full size dimensions and orientation (portrait/landscape/random), then plug that and your initial generation dimensions into the *Ideal Size Stepper* and get 1, 2, or 3 intermediate pairs of dimensions for upscaling. Note this does not output the initial size or full size dimensions: the 1, 2, or 3 outputs of this node are only the intermediate sizes.
A third node is included, *Random Switch (Integers)*, which is just a generic version of Final Size with no orientation selection.
**Node Link:** https://github.com/dwringer/size-stepper-nodes
**Example Usage:**
![size stepper usage graph](https://raw.githubusercontent.com/dwringer/size-stepper-nodes/main/size_nodes_usage.jpg)
--------------------------------
### Text font to Image
**Description:** text font to text image node for InvokeAI, download a font to use (or if in font cache uses it from there), the text is always resized to the image size, but can control that with padding, optional 2nd line
**Node Link:** https://github.com/mickr777/textfontimage

# Example Workflows
We've curated some example workflows for you to get started with Workflows in InvokeAI
To use them, right click on your desired workflow, press "Download Linked File". You can then use the "Load Workflow" functionality in InvokeAI to load the workflow and start generating images!
If you're interested in finding more workflows, checkout the [#share-your-workflows](https://discord.com/channels/1020123559063990373/1130291608097661000) channel in the InvokeAI Discord.

# Nodes
## What are Nodes?
An Node is simply a single operation that takes in inputs and returns
out outputs. Multiple nodes can be linked together to create more
complex functionality. All InvokeAI features are added through nodes.
### Anatomy of a Node
Individual nodes are made up of the following:
- Inputs: Edge points on the left side of the node window where you connect outputs from other nodes.
- Outputs: Edge points on the right side of the node window where you connect to inputs on other nodes.
- Options: Various options which are either manually configured, or overridden by connecting an output from another node to the input.
With nodes, you can can easily extend the image generation capabilities of InvokeAI, and allow you build workflows that suit your needs.
You can read more about nodes and the node editor [here](../nodes/NODES.md).
To get started with nodes, take a look at some of our examples for [common workflows](../nodes/exampleWorkflows.md)
## Downloading New Nodes
To download a new node, visit our list of [Community Nodes](../nodes/communityNodes.md). These are nodes that have been created by the community, for the community.
