Quick Start

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

If upgrading from version 2.3, please read Migrating a 2.3 root directory to 3.0 first.

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. Windows: double-click on the install.bat script. macOS: Open a Terminal window, drag the file install.sh from Finder into the Terminal, and press return. 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 developers and users familiar with Terminals)

You must have Python 3.10 through 3.11 installed on your machine. Earlier or later versions are not supported. Node.js also needs to be installed along with yarn (can be installed with the command npm install -g yarn if needed)

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/cu118
   

   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 --root .
   

   Don't miss the dot at the end!

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

Migrating a v2.3 InvokeAI root directory

The InvokeAI root directory is where the InvokeAI startup file, installed models, and generated images are stored. It is ordinarily named invokeai and located in your home directory. The contents and layout of this directory has changed between versions 2.3 and 3.0 and cannot be used directly.

We currently recommend that you use the installer to create a new root directory named differently from the 2.3 one, e.g. invokeai-3 and then use a migration script to copy your 2.3 models into the new location. However, if you choose, you can upgrade this directory in place. This section gives both recipes.

Creating a new root directory and migrating old models

This is the safer recipe because it leaves your old root directory in place to fall back on.

1. Follow the instructions above to create and install InvokeAI in a directory that has a different name from the 2.3 invokeai directory. In this example, we will use "invokeai-3"

2. When you are prompted to select models to install, select a minimal set of models, such as stable-diffusion-v1.5 only.

3. After installation is complete launch invokeai.sh (Linux/Mac) or invokeai.bat and select option 8 "Open the developers console". This will take you to the command line.

4. Issue the command invokeai-migrate3 --from /path/to/v2.3-root --to /path/to/invokeai-3-root. Provide the correct --from and --to paths for your v2.3 and v3.0 root directories respectively.

This will copy and convert your old models from 2.3 format to 3.0 format and create a new models directory in the 3.0 directory. The old models directory (which contains the models selected at install time) will be renamed models.orig and can be deleted once you have confirmed that the migration was successful.

If you wish, you can pass the 2.3 root directory to both --from and --to in order to update in place. Warning: this directory will no longer be usable with InvokeAI 2.3.

Migrating in place

For the adventurous, you may do an in-place upgrade from 2.3 to 3.0 without touching the command line. *This recipe does not work on Windows platforms due to a bug in the Windows version of the 2.3 upgrade script. See the next section for a Windows recipe.

For Mac and Linux Users:

1. Launch the InvokeAI launcher script in your current v2.3 root directory.

2. Select option [9] "Update InvokeAI" to bring up the updater dialog.

3. Select option [1] to upgrade to the latest release.

4. Once the upgrade is finished you will be returned to the launcher menu. Select option [7] "Re-run the configure script to fix a broken install or to complete a major upgrade".

This will run the configure script against the v2.3 directory and update it to the 3.0 format. The following files will be replaced:

• The invokeai.init file, replaced by invokeai.yaml
• The models directory
• The configs/models.yaml model index

The original versions of these files will be saved with the suffix ".orig" appended to the end. Once you have confirmed that the upgrade worked, you can safely remove these files. Alternatively you can restore a working v2.3 directory by removing the new files and restoring the ".orig" files' original names.

For Windows Users:

Windows Users can upgrade with the

1. Enter the 2.3 root directory you wish to upgrade
2. Launch invoke.sh or invoke.bat
3. Select the "Developer's console" option [8]
4. Type the following commands

pip install "invokeai @ https://github.com/invoke-ai/InvokeAI/archive/refs/tags/v3.0.0" --use-pep517 --upgrade
invokeai-configure --root .

(Replace v3.0.0 with the current release number if this document is out of date).

The first command will install and upgrade new software to run InvokeAI. The second will prepare the 2.3 directory for use with 3.0. You may now launch the WebUI in the usual way, by selecting option [1] from the launcher script

Migrating Images

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:

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.

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

You will need one of the following:

• An NVIDIA-based graphics card with 4 GB or more VRAM memory. 6-8 GB of VRAM is highly recommended for rendering using the Stable Diffusion XL models
• An Apple computer with an M1 chip.
• An AMD-based graphics card with 4GB or more VRAM memory (Linux only), 6-8 GB for XL rendering.

We do not recommend the GTX 1650 or 1660 series video cards. They are unable to run in half-precision mode and do not have sufficient VRAM to render 512x512 images.

Memory - At least 12 GB Main Memory RAM.

Disk - At least 12 GB of free disk space for the machine learning model, Python, and all its dependencies.
