 The Docker daemon on the system must be already set up to use the GPU. In case of Linux, this involves installing `nvidia-docker-runtime` and configuring the `nvidia` runtime as default. Steps will be different for AMD. Please see Docker documentation for the most up-to-date instructions for using your GPU with Docker.
 
+To use an AMD GPU, set `GPU_DRIVER=rocm` in your `.env` file.

+
+##  The API
+
+The default download queue is `DownloadQueueService`, an
+implementation of ABC `DownloadQueueServiceBase`. It juggles multiple
+background download requests and provides facilities for interrogating
+and cancelling the requests. Access to a current or past download task
+is mediated via `DownloadJob` objects which report the current status
+of a job request
+
+### The Queue Object
+
+A default download queue is located in
+`ApiDependencies.invoker.services.download_queue`. However, you can
+create additional instances if you need to isolate your queue from the
+main one.
+
+```
+queue = DownloadQueueService(event_bus=events)
+```
+
+`DownloadQueueService()` takes three optional arguments:
+
+| **Argument** | **Type**          |  **Default**  | **Description** |
+|----------------|-----------------|---------------|-----------------|
+| `max_parallel_dl`  | int                         | 5    | Maximum number of simultaneous downloads allowed |
+| `event_bus` | EventServiceBase   | None | System-wide FastAPI event bus for reporting download events |
+| `requests_session` | requests.sessions.Session   | None | An alternative requests Session object to use for the download |
+
+`max_parallel_dl` specifies how many download jobs are allowed to run
+simultaneously. Each will run in a different thread of execution.
+
+`event_bus` is an EventServiceBase, typically the one created at
+InvokeAI startup. If present, download events are periodically emitted

+
+### The Job object
+
+The queue operates on a series of download job objects. These objects
+specify the source and destination of the download, and keep track of
+the progress of the download.
+
+The only job type currently implemented is `DownloadJob`, a pydantic object with the
+following fields:
+
+| **Field**      | **Type**        |  **Default**  | **Description** |
+|----------------|-----------------|---------------|-----------------|
+| _Fields passed in at job creation time_                               |
+| `source`         | AnyHttpUrl      |               | Where to download from |
+| `dest`           | Path            |               | Where to download to              |
+| `access_token`   | str             |               | [optional] string containing authentication token for access |
+| `on_start`       | Callable        |               | [optional] callback when the download starts |
+| `on_progress`    | Callable        |               | [optional] callback called at intervals during download progress |
+| `on_complete`    | Callable        |               | [optional] callback called after successful download completion |
+| `on_error`       | Callable        |               | [optional] callback called after an error occurs  |
+| `id`             | int             | auto assigned | Job ID, an integer >= 0           |
+| `priority`       | int             | 10            | Job priority. Lower priorities run before higher priorities |
+|                                                                                                        |
+| _Fields updated over the course of the download task_
+| `status`         | DownloadJobStatus|              | Status code                                |
+| `download_path`  | Path |              | Path to the location of the downloaded file |
+| `job_started`    | float            |              | Timestamp for when the job started running |
+| `job_ended`      | float            |              | Timestamp for when the job completed or errored out |
+| `job_sequence`   | int              |              | A counter that is incremented each time a model is dequeued |
+| `bytes`          | int              | 0            | Bytes downloaded so far   |
+| `total_bytes`    | int              | 0            | Total size of the file at the remote site  |
+| `error_type`     | str              |              | String version of the exception that caused an error during download |
+| `error`          | str              |              | String version of the traceback associated with an error |
+| `cancelled`      | bool             | False        | Set to true if the job was cancelled by the caller|
+
+When you create a job, you can assign it a `priority`. If multiple
+jobs are queued, the job with the lowest priority runs first.
+
+Every job has a `source` and a `dest`. `source` is a pydantic.networks AnyHttpUrl object.
+The `dest` is a path on the local filesystem that specifies the
+destination for the downloaded object. Its semantics are
+described below.
+
+When the job is submitted, it is assigned a numeric `id`. The id can
+then be used to fetch the job object from the queue.
+
+The `status` field is updated by the queue to indicate where the job
+is in its lifecycle. Values are defined in the string enum
+`DownloadJobStatus`, a symbol available from
+`invokeai.app.services.download_manager`. Possible values are:
+
+| **Value**    |   **String Value**  | ** Description ** |
+|--------------|---------------------|-------------------|
+| `WAITING`      | waiting           | Job is on the queue but not yet running|
+| `RUNNING`      | running           | The download is started                |
+| `COMPLETED`    | completed         | Job has finished its work without an error |
+| `ERROR`        | error             | Job encountered an error and will not run again|
+
+`job_started` and `job_ended` indicate when the job
+was started (using a python timestamp) and when it completed.
+
+In case of an error, the job's status will be set to `DownloadJobStatus.ERROR`, the text of the
+Exception that caused the error will be placed in the `error_type`
+field and the traceback that led to the error will be in `error`.
+
+A cancelled job will have status `DownloadJobStatus.ERROR` and an
+`error_type` field of "DownloadJobCancelledException". In addition,
+the job's `cancelled` property will be set to True.
+
+### Callbacks
+
+Download jobs can be associated with a series of callbacks, each with
+the signature `Callable[["DownloadJob"], None]`. The callbacks are assigned
+using optional arguments `on_start`, `on_progress`, `on_complete` and
+`on_error`. When the corresponding event occurs, the callback wil be
+invoked and passed the job. The callback will be run in a `try:`
+context in the same thread as the download job. Any exceptions that
+occur during execution of the callback will be caught and converted
+into a log error message, thereby allowing the download to continue.
+
+#### `TqdmProgress`
+
+The `invokeai.app.services.download.download_default` module defines a
+class named `TqdmProgress` which can be used as an `on_progress`
+handler to display a completion bar in the console. Use as follows:
+
+```
+from invokeai.app.services.download import TqdmProgress
+
+download_queue.download(source='http://some.server.somewhere/some_file',
+                        dest='/tmp/downloads',
+                        on_progress=TqdmProgress().update
+                        )
+
+```
+
+### Events
+
+If the queue was initialized with the InvokeAI event bus (the case
+when using `ApiDependencies.invoker.services.download_queue`), then
+download events will also be issued on the bus. The events are:
+
+* `download_started` -- This is issued when a job is taken off the
+queue and a request is made to the remote server for the URL headers, but before any data
+has been downloaded. The event payload will contain the keys `source`
+and `download_path`. The latter contains the path that the URL will be
+downloaded to.
+
+* `download_progress -- This is issued periodically as the download
+runs. The payload contains the keys `source`, `download_path`,
+`current_bytes` and `total_bytes`. The latter two fields can be
+used to display the percent complete.
+
+* `download_complete` -- This is issued when the download completes
+successfully. The payload contains the keys `source`, `download_path`
+and `total_bytes`.
+
+* `download_error` -- This is issued when the download stops because
+of an error condition. The payload contains the fields `error_type`
+and `error`. The former is the text representation of the exception,
+and the latter is a traceback showing where the error occurred.
+
+### Job control
+
+To create a job call the queue's `download()` method. You can list all
+jobs using `list_jobs()`, fetch a single job by its with
+`id_to_job()`, cancel a running job with `cancel_job()`, cancel all
+running jobs with `cancel_all_jobs()`, and wait for all jobs to finish
+with `join()`.
+
+#### job = queue.download(source, dest, priority, access_token)
+
+Create a new download job and put it on the queue, returning the
+DownloadJob object.
+
+#### jobs = queue.list_jobs()
+
+Return a list of all active and inactive `DownloadJob`s.
+
+#### job = queue.id_to_job(id)
+
+Return the job corresponding to given ID.
+
+Return a list of all active and inactive `DownloadJob`s.
+
+#### queue.prune_jobs()
+
+Remove inactive (complete or errored) jobs from the listing returned
+by `list_jobs()`.
+
+#### queue.join()
+
+Block until all pending jobs have run to completion or errored out.

+## Model installation
+
+The `ModelInstallService` class implements the
+`ModelInstallServiceBase` abstract base class, and provides a one-stop
+shop for all your model install needs. It provides the following
+functionality:
+
+- Registering a model config record for a model already located on the
+  local filesystem, without moving it or changing its path.
+  
+- Installing a model alreadiy located on the local filesystem, by
+  moving it into the InvokeAI root directory under the
+  `models` folder (or wherever config parameter `models_dir`
+  specifies).
+	
+- Probing of models to determine their type, base type and other key
+  information.
+  
+- Interface with the InvokeAI event bus to provide status updates on
+  the download, installation and registration process.
+  
+- Downloading a model from an arbitrary URL and installing it in
+  `models_dir` (_implementation pending_).
+  
+- Special handling for Civitai model URLs which allow the user to
+  paste in a model page's URL or download link (_implementation pending_).
+
+  
+- Special handling for HuggingFace repo_ids to recursively download
+  the contents of the repository, paying attention to alternative
+  variants such as fp16. (_implementation pending_)
+  
+### Initializing the installer
+
+A default installer is created at InvokeAI api startup time and stored
+in `ApiDependencies.invoker.services.model_install` and can
+also be retrieved from an invocation's `context` argument with
+`context.services.model_install`.
+
+In the event you wish to create a new installer, you may use the
+following initialization pattern:
+
+```
+from invokeai.app.services.config import InvokeAIAppConfig
+from invokeai.app.services.model_records import ModelRecordServiceSQL
+from invokeai.app.services.model_install import ModelInstallService
+from invokeai.app.services.shared.sqlite import SqliteDatabase
+from invokeai.backend.util.logging import InvokeAILogger
+
+config = InvokeAIAppConfig.get_config()
+config.parse_args()
+logger = InvokeAILogger.get_logger(config=config)
+db = SqliteDatabase(config, logger)
+
+store = ModelRecordServiceSQL(db)
+installer = ModelInstallService(config, store)
+```
+
+The full form of `ModelInstallService()` takes the following
+required parameters:
+
+| **Argument**     | **Type**                     | **Description**              |
+|------------------|------------------------------|------------------------------|
+| `config`         | InvokeAIAppConfig       | InvokeAI app configuration object |
+| `record_store`   | ModelRecordServiceBase  | Config record storage database |
+| `event_bus`      | EventServiceBase        | Optional event bus to send download/install progress events to |
+
+Once initialized, the installer will provide the following methods:
+
+#### install_job = installer.import_model()
+
+The `import_model()` method is the core of the installer. The
+following illustrates basic usage:
+
+```
+from invokeai.app.services.model_install import (
+	LocalModelSource,
+	HFModelSource,
+	URLModelSource,
+)
+
+source1 = LocalModelSource(path='/opt/models/sushi.safetensors')   # a local safetensors file
+source2 = LocalModelSource(path='/opt/models/sushi_diffusers')     # a local diffusers folder
+
+source3 = HFModelSource(repo_id='runwayml/stable-diffusion-v1-5')  # a repo_id
+source4 = HFModelSource(repo_id='runwayml/stable-diffusion-v1-5', subfolder='vae')  # a subfolder within a repo_id
+source5 = HFModelSource(repo_id='runwayml/stable-diffusion-v1-5', variant='fp16')   # a named variant of a HF model
+
+source6 = URLModelSource(url='https://civitai.com/api/download/models/63006')       # model located at a URL
+source7 = URLModelSource(url='https://civitai.com/api/download/models/63006', access_token='letmein') # with an access token
+
+for source in [source1, source2, source3, source4, source5, source6, source7]:
+   install_job = installer.install_model(source)
+   
+source2job = installer.wait_for_installs()
+for source in sources:
+    job = source2job[source]
+	if job.status == "completed":
+		model_config = job.config_out
+		model_key = model_config.key
+		print(f"{source} installed as {model_key}")
+	elif job.status == "error":
+	    print(f"{source}: {job.error_type}.\nStack trace:\n{job.error}")
+	
+```
+
+As shown here, the `import_model()` method accepts a variety of
+sources, including local safetensors files, local diffusers folders,
+HuggingFace repo_ids with and without a subfolder designation,
+Civitai model URLs and arbitrary URLs that point to checkpoint files
+(but not to folders).
+
+Each call to `import_model()` return a `ModelInstallJob` job, 
+an object which tracks the progress of the install.
+
+If a remote model is requested, the model's files are downloaded in
+parallel across a multiple set of threads using the download
+queue. During the download process, the `ModelInstallJob` is updated
+to provide status and progress information. After the files (if any)
+are downloaded, the remainder of the installation runs in a single
+serialized background thread. These are the model probing, file
+copying, and config record database update steps.
+
+Multiple install jobs can be queued up. You may block until all
+install jobs are completed (or errored) by calling the
+`wait_for_installs()` method as shown in the code
+example. `wait_for_installs()` will return a `dict` that maps the
+requested source to its job. This object can be interrogated
+to determine its status. If the job errored out, then the error type
+and details can be recovered from `job.error_type` and `job.error`.
+
+The full list of arguments to `import_model()` is as follows:
+
+| **Argument**     | **Type**                     | **Default** | **Description**                           |
+|------------------|------------------------------|-------------|-------------------------------------------|
+| `source`         | Union[str, Path, AnyHttpUrl] |             | The source of the model, Path, URL or repo_id |
+| `inplace`        | bool                         | True        | Leave a local model in its current location |
+| `variant`        | str                          | None        | Desired variant, such as 'fp16' or 'onnx' (HuggingFace only) |
+| `subfolder`      | str                          | None        | Repository subfolder (HuggingFace only)   |
+| `config`         | Dict[str, Any]               | None        | Override all or a portion of model's probed attributes |
+| `access_token`   | str                          | None        | Provide authorization information needed to download |
+
+
+The `inplace` field controls how local model Paths are handled. If
+True (the default), then the model is simply registered in its current
+location by the installer's `ModelConfigRecordService`. Otherwise, a
+copy of the model put into the location specified by the `models_dir`
+application configuration parameter.
+
+The `variant` field is used for HuggingFace repo_ids only. If
+provided, the repo_id download handler will look for and download
+tensors files that follow the convention for the selected variant:
+
+- "fp16" will select files named "*model.fp16.{safetensors,bin}"
+- "onnx" will select files ending with the suffix ".onnx"
+- "openvino" will select files beginning with "openvino_model"
+
+In the special case of the "fp16" variant, the installer will select
+the 32-bit version of the files if the 16-bit version is unavailable.
+
+`subfolder` is used for HuggingFace repo_ids only. If provided, the
+model will be downloaded from the designated subfolder rather than the
+top-level repository folder. If a subfolder is attached to the repo_id
+using the format `repo_owner/repo_name:subfolder`, then the subfolder
+specified by the repo_id will override the subfolder argument.
+
+`config` can be used to override all or a portion of the configuration
+attributes returned by the model prober. See the section below for
+details.
+
+`access_token` is passed to the download queue and used to access
+repositories that require it.
+
+#### Monitoring the install job process
+
+When you create an install job with `import_model()`, it launches the
+download and installation process in the background and returns a
+`ModelInstallJob` object for monitoring the process.
+
+The `ModelInstallJob` class has the following structure:
+
+| **Attribute** | **Type**        |  **Description** |
+|----------------|-----------------|------------------|
+| `status`       | `InstallStatus`  | An enum of ["waiting", "running", "completed" and "error" |
+| `config_in`    | `dict`          | Overriding configuration values provided by the caller |
+| `config_out`   | `AnyModelConfig`| After successful completion, contains the configuration record written to the database | 
+| `inplace`      | `boolean`       | True if the caller asked to install the model in place using its local path | 
+| `source`       | `ModelSource`   | The local path, remote URL or repo_id of the model to be installed | 
+| `local_path`   | `Path`          | If a remote model, holds the path of the model after it is downloaded; if a local model, same as `source` |
+| `error_type`   | `str`           | Name of the exception that led to an error status |
+| `error`        | `str`           | Traceback of the error |
+
+
+If the `event_bus` argument was provided, events will also be
+broadcast to the InvokeAI event bus. The events will appear on the bus
+as an event of type `EventServiceBase.model_event`, a timestamp and
+the following event names:
+
+- `model_install_started`
+
+The payload will contain the keys `timestamp` and `source`. The latter
+indicates the requested model source for installation.
+
+- `model_install_progress`
+
+Emitted at regular intervals when downloading a remote model, the
+payload will contain the keys `timestamp`, `source`, `current_bytes`
+and `total_bytes`. These events are _not_ emitted when a local model
+already on the filesystem is imported.
+
+- `model_install_completed`
+
+Issued once at the end of a successful installation. The payload will
+contain the keys `timestamp`, `source` and `key`, where `key` is the
+ID under which the model has been registered.
+
+- `model_install_error`
+
+Emitted if the installation process fails for some reason. The payload
+will contain the keys `timestamp`, `source`, `error_type` and
+`error`. `error_type` is a short message indicating the nature of the
+error, and `error` is the long traceback to help debug the problem.
+
+#### Model confguration and probing
+
+The install service uses the `invokeai.backend.model_manager.probe`
+module during import to determine the model's type, base type, and
+other configuration parameters. Among other things, it assigns a
+default name and description for the model based on probed
+fields. 
+
+When downloading remote models is implemented, additional
+configuration information, such as list of trigger terms, will be
+retrieved from the HuggingFace and Civitai model repositories.
+
+The probed values can be overriden by providing a dictionary in the
+optional `config` argument passed to `import_model()`. You may provide
+overriding values for any of the model's configuration
+attributes. Here is an example of setting the
+`SchedulerPredictionType` and `name` for an sd-2 model:
+
+This is typically used to set
+the model's name and description, but can also be used to overcome
+cases in which automatic probing is unable to (correctly) determine
+the model's attribute. The most common situation is the
+`prediction_type` field for sd-2 (and rare sd-1) models. Here is an
+example of how it works:
+
+```
+install_job = installer.import_model(
+               source='stabilityai/stable-diffusion-2-1',
+			   variant='fp16',
+			   config=dict(
+			         prediction_type=SchedulerPredictionType('v_prediction')
+					 name='stable diffusion 2 base model',
+	           )
+	      )
+```
+
+### Other installer methods
+
+This section describes additional methods provided by the installer class.
+
+#### jobs = installer.wait_for_installs()
+
+Block until all pending installs are completed or errored and then
+returns a list of completed jobs.
+
+#### jobs = installer.list_jobs([source])
+
+Return a list of all active and complete `ModelInstallJobs`. An
+optional `source` argument allows you to filter the returned list by a
+model source string pattern using a partial string match.
+
+#### jobs = installer.get_job(source)
+
+Return a list of `ModelInstallJob` corresponding to the indicated
+model source.
+
+#### installer.prune_jobs
+
+Remove non-pending jobs (completed or errored) from the job list
+returned by `list_jobs()` and `get_job()`.
+
+#### installer.app_config, installer.record_store,
+installer.event_bus
+
+Properties that provide access to the installer's `InvokeAIAppConfig`,
+`ModelRecordServiceBase` and `EventServiceBase` objects.
+
+#### key = installer.register_path(model_path, config), key = installer.install_path(model_path, config)
+
+These methods bypass the download queue and directly register or
+install the model at the indicated path, returning the unique ID for
+the installed model.
+
+Both methods accept a Path object corresponding to a checkpoint or
+diffusers folder, and an optional dict of config attributes to use to
+override the values derived from model probing.
+
+The difference between `register_path()` and `install_path()` is that
+the former creates a model configuration record without changing the
+location of the model in the filesystem. The latter makes a copy of
+the model inside the InvokeAI models directory before registering
+it.
+
+#### installer.unregister(key)
+
+This will remove the model config record for the model at key, and is
+equivalent to `installer.record_store.del_model(key)`
+
+#### installer.delete(key)
+
+This is similar to `unregister()` but has the additional effect of
+conditionally deleting the underlying model file(s) if they reside
+within the InvokeAI models directory
+
+#### installer.unconditionally_delete(key)
+
+This method is similar to `unregister()`, but also unconditionally
+deletes the corresponding model weights file(s), regardless of whether
+they are inside or outside the InvokeAI models hierarchy.
+
+#### List[str]=installer.scan_directory(scan_dir: Path, install: bool)
+
+This method will recursively scan the directory indicated in
+`scan_dir` for new models and either install them in the models
+directory or register them in place, depending on the setting of
+`install` (default False).
+
+The return value is the list of keys of the new installed/registered
+models.
+
+#### installer.sync_to_config()
+
+This method synchronizes models in the models directory and autoimport
+directory to those in the `ModelConfigRecordService` database. New
+models are registered and orphan models are unregistered.
+
+#### installer.start(invoker)
+
+The `start` method is called by the API intialization routines when
+the API starts up. Its effect is to call `sync_to_config()` to
+synchronize the model record store database with what's currently on
+disk.

-## Model installation
-
-The `ModelInstallService` class implements the
-`ModelInstallServiceBase` abstract base class, and provides a one-stop
-shop for all your model install needs. It provides the following
-functionality:
-
-- Registering a model config record for a model already located on the
-  local filesystem, without moving it or changing its path.
-  
-- Installing a model alreadiy located on the local filesystem, by
-  moving it into the InvokeAI root directory under the
-  `models` folder (or wherever config parameter `models_dir`
-  specifies).
-	
-- Downloading a model from an arbitrary URL and installing it in
-  `models_dir`.
-  
-- Special handling for Civitai model URLs which allow the user to
-  paste in a model page's URL or download link. Any metadata provided
-  by Civitai, such as trigger terms, are captured and placed in the
-  model config record.
-  
-- Special handling for HuggingFace repo_ids to recursively download
-  the contents of the repository, paying attention to alternative
-  variants such as fp16.
-  
-- Probing of models to determine their type, base type and other key
-  information.
-  
-- Interface with the InvokeAI event bus to provide status updates on
-  the download, installation and registration process.
-  
-### Initializing the installer
-
-A default installer is created at InvokeAI api startup time and stored
-in `ApiDependencies.invoker.services.model_install_service` and can
-also be retrieved from an invocation's `context` argument with
-`context.services.model_install_service`.
-
-In the event you wish to create a new installer, you may use the
-following initialization pattern:
-
-```
-from invokeai.app.services.config import InvokeAIAppConfig
-from invokeai.app.services.download_manager import DownloadQueueServive
-from invokeai.app.services.model_record_service import ModelRecordServiceBase
-
-config = InvokeAI.get_config()
-queue = DownloadQueueService()
-store = ModelRecordServiceBase.open(config)
-installer = ModelInstallService(config=config, queue=queue, store=store)
-```
-
-The full form of `ModelInstallService()` takes the following
-parameters. Each parameter will default to a reasonable value, but it
-is recommended that you set them explicitly as shown in the above example.
-
-| **Argument**     | **Type**                     | **Default** | **Description**                           |
-|------------------|------------------------------|-------------|-------------------------------------------|
-| `config`         | InvokeAIAppConfig        | Use system-wide config  | InvokeAI app configuration object |
-| `queue`          | DownloadQueueServiceBase  | Create a new download queue for internal use  | Download queue |
-| `store`          | ModelRecordServiceBase  | Use config to select the database to open  | Config storage database |
-| `event_bus`      | EventServiceBase        | None | An event bus to send download/install progress events to |
-| `event_handlers` | List[DownloadEventHandler]  | None | Event handlers for the download queue |
-
-Note that if `store` is not provided, then the class will use
-`ModelRecordServiceBase.open(config)` to select the database to use.
-
-Once initialized, the installer will provide the following methods:
-
-#### install_job = installer.install_model()
-
-The `install_model()` method is the core of the installer. The
-following illustrates basic usage:
-
-```
-sources = [
-	Path('/opt/models/sushi.safetensors'),   # a local safetensors file
-	Path('/opt/models/sushi_diffusers/'),    # a local diffusers folder
-	'runwayml/stable-diffusion-v1-5',        # a repo_id
-    'runwayml/stable-diffusion-v1-5:vae',    # a subfolder within a repo_id
-	'https://civitai.com/api/download/models/63006', # a civitai direct download link
-	'https://civitai.com/models/8765?modelVersionId=10638',  # civitai model page
-	'https://s3.amazon.com/fjacks/sd-3.safetensors', # arbitrary URL
-]
-
-for source in sources:
-   install_job = installer.install_model(source)
-   
-source2key = installer.wait_for_installs()
-for source in sources:
-    model_key = source2key[source]
-	print(f"{source} installed as {model_key}")
-```
-
-As shown here, the `install_model()` method accepts a variety of
-sources, including local safetensors files, local diffusers folders,
-HuggingFace repo_ids with and without a subfolder designation,
-Civitai model URLs and arbitrary URLs that point to checkpoint files
-(but not to folders).
-
-Each call to `install_model()` will return a `ModelInstallJob` job, a
-subclass of `DownloadJobBase`. The install job has additional
-install-specific fields described in the next section.
-
-Each install job will run in a series of background threads using
-the object's download queue. You may block until all install jobs are
-completed (or errored) by calling the `wait_for_installs()` method as
-shown in the code example. `wait_for_installs()` will return a `dict`
-that maps the requested source to the key of the installed model. In
-the case that a model fails to download or install, its value in the
-dict will be None. The actual cause of the error will be reported in
-the corresponding job's `error` field.
-
-Alternatively you may install event handlers and/or listen for events
-on the InvokeAI event bus in order to monitor the progress of the
-requested installs.
-
-The full list of arguments to `model_install()` is as follows:
-
-| **Argument**     | **Type**                     | **Default** | **Description**                           |
-|------------------|------------------------------|-------------|-------------------------------------------|
-| `source`         | Union[str, Path, AnyHttpUrl] |             | The source of the model, Path, URL or repo_id |
-| `inplace`        | bool                         | True        | Leave a local model in its current location |
-| `variant`        | str                          | None        | Desired variant, such as 'fp16' or 'onnx' (HuggingFace only) |
-| `subfolder`      | str                          | None        | Repository subfolder (HuggingFace only)   |
-| `probe_override` | Dict[str, Any]               | None        | Override all or a portion of model's probed attributes |
-| `metadata`       | ModelSourceMetadata          | None        | Provide metadata that will be added to model's config |
-| `access_token`   | str                          | None        | Provide authorization information needed to download |
-| `priority`       | int                          | 10          | Download queue priority for the job       |
-
-
-The `inplace` field controls how local model Paths are handled. If
-True (the default), then the model is simply registered in its current
-location by the installer's `ModelConfigRecordService`. Otherwise, the
-model will be moved into the location specified by the  `models_dir`
-application configuration parameter. 
-
-The `variant` field is used for HuggingFace repo_ids only. If
-provided, the repo_id download handler will look for and download
-tensors files that follow the convention for the selected variant:
-
-- "fp16" will select files named "*model.fp16.{safetensors,bin}"
-- "onnx" will select files ending with the suffix ".onnx"
-- "openvino" will select files beginning with "openvino_model"
-
-In the special case of the "fp16" variant, the installer will select
-the 32-bit version of the files if the 16-bit version is unavailable.
-
-`subfolder` is used for HuggingFace repo_ids only. If provided, the
-model will be downloaded from the designated subfolder rather than the
-top-level repository folder. If a subfolder is attached to the repo_id
-using the format `repo_owner/repo_name:subfolder`, then the subfolder
-specified by the repo_id will override the subfolder argument.
-
-`probe_override` can be used to override all or a portion of the
-attributes returned by the model prober. This can be used to overcome
-cases in which automatic probing is unable to (correctly) determine
-the model's attribute. The most common situation is the
-`prediction_type` field for sd-2 (and rare sd-1) models. Here is an
-example of how it works:
-
-```
-install_job = installer.install_model(
-               source='stabilityai/stable-diffusion-2-1',
-			   variant='fp16',
-			   probe_override=dict(
-			         prediction_type=SchedulerPredictionType('v_prediction')
-	           )
-	      )
-```
-
-`metadata` allows you to attach custom metadata to the installed
-model. See the next section for details.
-
-`priority` and `access_token` are passed to the download queue and
-have the same effect as they do for the DownloadQueueServiceBase.
-
-#### Monitoring the install job process
-
-When you create an install job with `model_install()`, events will be
-passed to the list of `DownloadEventHandlers` provided at installer
-initialization time. Event handlers can also be added to individual
-model install jobs by calling their `add_handler()` method as
-described earlier for the `DownloadQueueService`.
-
-If the `event_bus` argument was provided, events will also be
-broadcast to the InvokeAI event bus. The events will appear on the bus
-as a singular event type named `model_event` with a payload of
-`job`. You can then retrieve the job and check its status.
-
-** TO DO: ** consider breaking `model_event` into
-`model_install_started`, `model_install_completed`, etc. The event bus
-features have not yet been tested with FastAPI/websockets, and it may
-turn out that the job object is not serializable.
-
-#### Model metadata and probing
-
-The install service has special handling for HuggingFace and Civitai
-URLs that capture metadata from the source and include it in the model
-configuration record. For example, fetching the Civitai model 8765
-will produce a config record similar to this (using YAML
-representation):
-
-```
-5abc3ef8600b6c1cc058480eaae3091e:
-  path: sd-1/lora/to8contrast-1-5.safetensors
-  name: to8contrast-1-5
-  base_model: sd-1
-  model_type: lora
-  model_format: lycoris
-  key: 5abc3ef8600b6c1cc058480eaae3091e
-  hash: 5abc3ef8600b6c1cc058480eaae3091e
-  description: 'Trigger terms: to8contrast style'
-  author: theovercomer8
-  license: allowCommercialUse=Sell; allowDerivatives=True; allowNoCredit=True
-  source: https://civitai.com/models/8765?modelVersionId=10638
-  thumbnail_url: null
-  tags:
-  - model
-  - style
-  - portraits
-```
-
-For sources that do not provide model metadata, you can attach custom
-fields by providing a `metadata` argument to `model_install()` using
-an initialized `ModelSourceMetadata` object (available for import from
-`model_install_service.py`):
-
-```
-from invokeai.app.services.model_install_service import ModelSourceMetadata
-meta = ModelSourceMetadata(
-                name="my model",
-				author="Sushi Chef",
-				description="Highly customized model; trigger with 'sushi',"
-				license="mit",
-				thumbnail_url="http://s3.amazon.com/ljack/pics/sushi.png",
-				tags=list('sfw', 'food')
-			)
-install_job = installer.install_model(
-               source='sushi_chef/model3',
-			   variant='fp16',
-			   metadata=meta,
-	      )
-```
-
-It is not currently recommended to provide custom metadata when
-installing from Civitai or HuggingFace source, as the metadata
-provided by the source will overwrite the fields you provide. Instead,
-after the model is installed you can use
-`ModelRecordService.update_model()` to change the desired fields.
-
-** TO DO: ** Change the logic so that the caller's metadata fields take
-precedence over those provided by the source.
-
-
-#### Other installer methods
-
-This section describes additional, less-frequently-used attributes and
-methods provided by the installer class.
-
-##### installer.wait_for_installs()
-
-This is equivalent to the `DownloadQueue` `join()` method. It will
-block until all the active jobs in the install queue have reached a
-terminal state (completed, errored or cancelled).
-
-##### installer.queue, installer.store, installer.config
-
-These attributes provide access to the `DownloadQueueServiceBase`,
-`ModelConfigRecordServiceBase`, and `InvokeAIAppConfig` objects that
-the installer uses.
-
-For example, to temporarily pause all pending installations, you can
-do this:
-
-```
-installer.queue.pause_all_jobs()
-```
-##### key = installer.register_path(model_path, overrides), key = installer.install_path(model_path, overrides)
-
-These methods bypass the download queue and directly register or
-install the model at the indicated path, returning the unique ID for
-the installed model.
-
-Both methods accept a Path object corresponding to a checkpoint or
-diffusers folder, and an optional dict of attributes to use to
-override the values derived from model probing.
-
-The difference between `register_path()` and `install_path()` is that
-the former will not move the model from its current position, while
-the latter will move it into the `models_dir` hierarchy.
-
-##### installer.unregister(key)
-
-This will remove the model config record for the model at key, and is
-equivalent to `installer.store.unregister(key)`
-
-##### installer.delete(key)
-
-This is similar to `unregister()` but has the additional effect of
-deleting the underlying model file(s) -- even if they were outside the
-`models_dir` directory!
-
-##### installer.conditionally_delete(key)
-
-This method will call `unregister()` if the model identified by `key`
-is outside the `models_dir` hierarchy, and call `delete()` if the
-model is inside.
-
-#### List[str]=installer.scan_directory(scan_dir: Path, install: bool)
-
-This method will recursively scan the directory indicated in
-`scan_dir` for new models and either install them in the models
-directory or register them in place, depending on the setting of
-`install` (default False).
-
-The return value is the list of keys of the new installed/registered
-models.
-
-#### installer.scan_models_directory()
-
-This method scans the models directory for new models and registers
-them in place. Models that are present in the
-`ModelConfigRecordService` database whose paths are not found will be
-unregistered.
-
-#### installer.sync_to_config()
-
-This method synchronizes models in the models directory and autoimport
-directory to those in the `ModelConfigRecordService` database. New
-models are registered and orphan models are unregistered.
-
-#### hash=installer.hash(model_path)
-
-This method is calls the fasthash algorithm on a model's Path
-(either a file or a folder) to generate a unique ID based on the
-contents of the model.
-
-##### installer.start(invoker)
-
-The `start` method is called by the API intialization routines when
-the API starts up. Its effect is to call `sync_to_config()` to
-synchronize the model record store database with what's currently on
-disk.
-
-This method should not ordinarily be called manually.

+# :material-library-shelves: LoRAs & LCM-LoRAs
+
+With the advances in research, many new capabilities are available to customize the knowledge and understanding of novel concepts not originally contained in the base model. 
+
+## LoRAs
+
+Low-Rank Adaptation (LoRA) files are models that customize the output of Stable Diffusion
+image generation.  Larger than embeddings, but much smaller than full
+models, they augment SD with improved understanding of subjects and
+artistic styles.
+
+Unlike TI files, LoRAs do not introduce novel vocabulary into the
+model's known tokens. Instead, LoRAs augment the model's weights that
+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.
+
+LoRAs are typically stored in .safetensors files, which are the most
+secure way to store and transmit these types of weights. You may
+install any number of `.safetensors` LoRA files simply by copying them
+into the `autoimport/lora` directory of the corresponding InvokeAI models
+directory (usually `invokeai` in your home directory).
+
+To use these when generating, open the LoRA menu item in the options
+panel, select the LoRAs you want to apply and ensure that they have
+the appropriate weight recommended by the model provider. Typically,
+most LoRAs perform best at a weight of .75-1.
+
+
+## LCM-LoRAs
+Latent Consistency Models (LCMs) allowed a reduced number of steps to be used to generate images with Stable Diffusion. These are created by distilling base models, creating models that only require a small number of steps to generate images. However, LCMs require that any fine-tune of a base model be distilled to be used as an LCM. 
+
+LCM-LoRAs are models that provide the benefit of LCMs but are able to be used as LoRAs and applied to any fine tune of a base model. LCM-LoRAs are created by training a small number of adapters, rather than distilling the entire fine-tuned base model. The resulting LoRA can be used the same way as a standard LoRA, but with a greatly reduced step count. This enables SDXL images to be generated up to 10x faster than without the use of LCM-LoRAs. 
+
+
+**Using LCM-LoRAs**
+
+LCM-LoRAs are natively supported in InvokeAI throughout the application. To get started, install any diffusers format LCM-LoRAs using the model manager and select it in the LoRA field.
+
+There are a number parameter differences when using LCM-LoRAs and standard generation: 
+
+- When using LCM-LoRAs, the LoRA strength should be lower than if using a standard LoRA, with 0.35 recommended as a starting point.  
+- The LCM scheduler should be used for generation
+- CFG-Scale should be reduced to ~1
+- Steps should be reduced in the range of 4-8
+
+Standard LoRAs can also be used alongside LCM-LoRAs, but will also require a lower strength, with 0.45 being recommended as a starting point.

+# FAQs
+
+**Where do I get started? How can I install Invoke?**
+
+- You can download the latest installers [here](https://github.com/invoke-ai/InvokeAI/releases) - Note that any releases marked as *pre-release* are in a beta state. You may experience some issues, but we appreciate your help testing those! For stable/reliable installations, please install the **[Latest Release](https://github.com/invoke-ai/InvokeAI/releases/latest)**
+
+**How can I download models? Can I use models I already have downloaded?**
+
+- Models can be downloaded through the model manager, or through option [4] in the invoke.bat/invoke.sh launcher script. To download a model through the Model Manager, use the HuggingFace Repo ID by pressing the “Copy” button next to the repository name. Alternatively, to download a model from CivitAi, use the download link in the Model Manager.
+- Models that are already downloaded can be used by creating a symlink to the model location in the `autoimport` folder or by using the Model Manger’s “Scan for Models” function.
+
+**My images are taking a long time to generate. How can I speed up generation?** 
+
+- A common solution is to reduce the size of your RAM & VRAM cache to 0.25. This ensures your system has enough memory to generate images.
+- Additionally, check the [hardware requirements](https://invoke-ai.github.io/InvokeAI/#hardware-requirements) to ensure that your system is capable of generating images.
+- Lastly, double check your generations are happening on your GPU (if you have one). InvokeAI will log what is being used for generation upon startup. 
+
+**I’ve installed Python on Windows but the installer says it can’t find it?**
+
+- Then ensure that you checked  **'Add python.exe to PATH'** when installing Python. This can be found at the bottom of the Python Installer window. If you already have Python installed, this can be done with the modify / repair feature of the installer.
+
+**I’ve installed everything successfully but I still get an error about Triton when starting Invoke?**
+
+- This can be safely ignored. InvokeAI doesn't use Triton, but if you are on Linux and wish to dismiss the error, you can install Triton.
+
+**I updated to 3.4.0 and now xFormers can’t load C++/CUDA?**
+
+- An issue occurred with your PyTorch update. Follow these steps to fix :
+    1. Launch your invoke.bat / invoke.sh and select the option to open the developer console
+    2. Run:`pip install ".[xformers]" --upgrade --force-reinstall --extra-index-url https://download.pytorch.org/whl/cu121`
+    - If you run into an error with `typing_extensions`, re-open the developer console and run:  `pip install -U typing-extensions`
+
+**It says my pip is out of date - is that why my install isn't working?**
+- An out of date won't cause an installation to fail. The cause of the error can likely be found above the message that says pip is out of date.
+- If you saw that warning but the install went well, don't worry about it (but you can update pip afterwards if you'd like).   
+
+**How can I generate the exact same that I found on the internet?**
+Most example images with prompts that you'll find on the internet have been generated using different software, so you can't expect to get identical results. In order to reproduce an image, you need to replicate the exact settings and processing steps, including (but not limited to) the model, the positive and negative prompts, the seed, the sampler, the exact image size, any upscaling steps, etc.

 ### XY Image to Grid and Images to Grids nodes
 
-**Description:** Image to grid nodes and supporting tools.
+**Description:** These nodes add the following to InvokeAI:
+- Generate grids of images from multiple input images
+- Create XY grid images with labels from parameters
+- Split images into overlapping tiles for processing (for super-resolution workflows)
+- Recombine image tiles into a single output image blending the seams 
 
-1. "Images To Grids" node - Takes a collection of images and creates a grid(s) of images. If there are more images than the size of a single grid then multiple grids will be created until it runs out of images.
-2. "XYImage To Grid" node - Converts a collection of XYImages into a labeled Grid of images. The XYImages collection has to be built using the supporting nodes. See example node setups for more details.
+The nodes include:
+1. `Images To Grids` - Combine multiple images into a grid of images
+2. `XYImage To Grid` - Take X & Y params and creates a labeled image grid.
+3. `XYImage Tiles` - Super-resolution (embiggen) style tiled resizing
+4. `Image Tot XYImages` - Takes an image and cuts it up into a number of columns and rows.
+5. Multiple supporting nodes - Helper nodes for data wrangling and building `XYImage` collections
