Version InvokeAI Version 2.2.4 - A Stable Diffusion Toolkit

With InvokeAI 2.2, this project now provides enthusiasts and professionals a robust workflow solution for creating AI-generated and human facilitated compositions. Additional enhancements have been made as well, improving safety, ease of use, and installation.

Optimized for efficiency, InvokeAI needs only ~3.5GB of VRAM to generate a 512x768 image (and less for smaller images), and is compatible with Windows/Linux/Mac (M1 & M2).

You can see the release video here, which introduces the main WebUI enhancement for version 2.2 - The Unified Canvas. This new workflow is the biggest enhancement added to the WebUI to date, and unlocks a stunning amount of potential for users to create and iterate on their creations. The following sections describe what’s new for InvokeAI.

Version 2.2.4 is a bugfix release. The major user-visible change is that we have overhauled the installation experience to make it faster and more stable. Please see Installation Overview for instructions on using the new installer, and see the .zip files in the Assets section below for the installer for your preferred platform. Note that you will need to install Python 3.9 or 3.10 to use the new installation method.

The new installers are located here. They have been updated 13 December in order to prevent a segfault crash on certain Macintosh systems.

There are a number of installation-related changes that previous InvokeAI users should be aware of:

Everything now lives in the invokeai directory.

Previously there were two directories to worry about, the directory that contained the InvokeAI source code and the launcher scripts, and the invokeai directory that contained the models files, embeddings, configuration and outputs. With the 2.2.4 release, this dual system is done away with, and everything, including the invoke.bat and invoke.sh launcher scripts, now live in a directory named invokeai. By default this directory is located in your home directory (e.g. \Users\yourname on Windows), but you can select where it goes at install time.

InvokeAI-installer-2.2.4-p5-linux.zip InvokeAI-installer-2.2.4-p5-mac.zip InvokeAI-installer-2.2.4-p5-windows.zip

After installation, you can delete the install directory (the one that the zip file creates when it unpacks). Do not delete or move the invokeai directory!

The .invokeai initialization file has been renamed invokeai/invokeai.init

You can place frequently-used startup options in this file, such as the default number of steps or your preferred sampler. To keep everything in one place, this file has now been moved into the invokeai directory and is named invokeai.init.

To update from Version 2.2.3

The easiest route is to download and unpack one of the 2.2.4 installer files. When it asks you for the location of the invokeai runtime directory, respond with the path to the directory that contains your 2.2.3 invokeai. That is, if invokeai lives at C:\Users\fred\invokeai, then answer with C:\Users\fred and answer “Y” when asked if you want to reuse the directory.

The update.sh (update.bat) script that came with the 2.2.3 source installer does not know about the new directory layout and won’t be fully functional.

To update to 2.2.5 (and beyond) there’s now an update path.

As they become available, you can update to more recent versions of InvokeAI using an update.sh (update.bat) script located in the invokeai directory. Running it without any arguments will install the most recent version of InvokeAI. Alternatively, you can get set releases by running the update.sh script with an argument in the command shell. This syntax accepts the path to the desired release’s zip file, which you can find by clicking on the green “Code” button on this repository’s home page. Here are some examples:
