InvokeAI: A Stable Diffusion Toolkit

Note: The UI is not fully functional on main. If you need a stable UI based on main, use the pre-nodes tag while we migrate to a new backend.

InvokeAI is a leading creative engine built to empower professionals and enthusiasts alike. Generate and create stunning visual media using the latest AI-driven technologies. InvokeAI offers an industry leading Web Interface, interactive Command Line Interface, and also serves as the foundation for multiple commercial products.

FOR DEVELOPERS - MIGRATING TO THE 3.0.0 MODELS FORMAT

The models directory and models.yaml have changed. To migrate to the new layout, please follow this recipe:

1. Run `python scripts/migrate_models_to_3.0.py <path_to_root_directory>

2. This will create a new models directory named models-3.0 and a new config directory named models.yaml-3.0, both in the current working directory. If you prefer to name them something else, pass the --dest-directory and/or --dest-yaml arguments.

3. Check that the new models directory and yaml file look ok.

4. Replace the existing directory and file, keeping backup copies just in case.

Getting Started with InvokeAI

For full installation and upgrade instructions, please see: InvokeAI Installation Overview

Automatic Installer (suggested for 1st time users)

1. Go to the bottom of the Latest Release Page

2. Download the .zip file for your OS (Windows/macOS/Linux).

3. Unzip the file.

4. If you are on Windows, double-click on the install.bat script. On macOS, open a Terminal window, drag the file install.sh from Finder into the Terminal, and press return. On Linux, run install.sh.

5. You'll be asked to confirm the location of the folder in which to install InvokeAI and its image generation model files. Pick a location with at least 15 GB of free memory. More if you plan on installing lots of models.

6. Wait while the installer does its thing. After installing the software, the installer will launch a script that lets you configure InvokeAI and select a set of starting image generation models.

7. Find the folder that InvokeAI was installed into (it is not the same as the unpacked zip file directory!) The default location of this folder (if you didn't change it in step 5) is ~/invokeai on Linux/Mac systems, and C:\Users\YourName\invokeai on Windows. This directory will contain launcher scripts named invoke.sh and invoke.bat.

8. On Windows systems, double-click on the invoke.bat file. On macOS, open a Terminal window, drag invoke.sh from the folder into the Terminal, and press return. On Linux, run invoke.sh

9. Press 2 to open the "browser-based UI", press enter/return, wait a minute or two for Stable Diffusion to start up, then open your browser and go to http://localhost:9090.

10. Type banana sushi in the box on the top left and click Invoke

Command-Line Installation (for users familiar with Terminals)

You must have Python 3.9 or 3.10 installed on your machine. Earlier or later versions are not supported.

1. Open a command-line window on your machine. The PowerShell is recommended for Windows.

2. Create a directory to install InvokeAI into. You'll need at least 15 GB of free space:

   mkdir invokeai
   

3. Create a virtual environment named .venv inside this directory and activate it:

   cd invokeai
   python -m venv .venv --prompt InvokeAI
   

4. Activate the virtual environment (do it every time you run InvokeAI)

   For Linux/Mac users:

   source .venv/bin/activate
   

   For Windows users:

   .venv\Scripts\activate
   

5. Install the InvokeAI module and its dependencies. Choose the command suited for your platform & GPU.

   For Windows/Linux with an NVIDIA GPU:

   pip install "InvokeAI[xformers]" --use-pep517 --extra-index-url https://download.pytorch.org/whl/cu117
   

   For Linux with an AMD GPU:

   pip install InvokeAI --use-pep517 --extra-index-url https://download.pytorch.org/whl/rocm5.4.2
   

   For non-GPU systems:

   pip install InvokeAI --use-pep517 --extra-index-url https://download.pytorch.org/whl/cpu
   

   For Macintoshes, either Intel or M1/M2:

   pip install InvokeAI --use-pep517
   

6. Configure InvokeAI and install a starting set of image generation models (you only need to do this once):

   invokeai-configure
   

7. Launch the web server (do it every time you run InvokeAI):

   invokeai --web
   

8. Point your browser to http://localhost:9090 to bring up the web interface.

9. Type banana sushi in the box on the top left and click Invoke.

Be sure to activate the virtual environment each time before re-launching InvokeAI, using source .venv/bin/activate or .venv\Scripts\activate.

Detailed Installation Instructions

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). For full installation and upgrade instructions, please see: InvokeAI Installation Overview

Hardware Requirements

InvokeAI is supported across Linux, Windows and macOS. Linux users can use either an Nvidia-based card (with CUDA support) or an AMD card (using the ROCm driver).

System
