Releases

InvokeAI v3.5.0

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 and also serves as the foundation for multiple commercial products.

To learn more about InvokeAI, please visit our Documentation or join our Discord server!

🌟 What’s New in 3.5.0:

Workflow Library

Until now, a workflow could only be associated with an image, or be downloaded as JSON. The Workflow Library allows workflows to be saved independently to the database. The UI provides sorting and filtering options to manage them.

With the Workflow Library, we can now ship default workflows directly in the app. You’ll see a couple on the Default tab. As the InvokeAI application evolves we will keep these workflows up-to-date, and regularly add more.

Other Enhancements

  • More capable node updating
  • Better errors when your workflow doesn’t match your installed nodes
  • Community node packs auto-report their name, so if your workflow needs nodes you don’t have installed, you’ll see what’s missing
  • Custom field types for nodes
  • Tiled upscaling nodes (BETA)
  • Added many missing translation strings
  • Gallery auto-scroll

‼️ Things to Know:

Invoke might revert to CPU (NVIDA GPU only)

  • Some users have experienced torch reverting to the CPU rather than their GPU. To fix this follow these steps:
  1. Launch your invoke.bat / invoke.sh and select the option to open the developer console
  2. Run: pip install --force-reinstall torch==2.1.2 --index-url https://download.pytorch.org/whl/cu121
  3. If you run into an error with typing_extensions, run: pip install -U typing-extensions
  4. If there is an error with fsspec, run pip install -U fsspec==2023.5.0

Database Migrations

As the app evolves and our database usage gets a bit more complex, we need a way to safely update it. This release introduces a database migration utility and versions the database.

The first time you run v3.5.0, the migrator will set up the database versioning and, for this particular release, updates the images table to flag if an image has a workflow embedded or not. You’ll see a progress bar as it checks each image - it should be pretty quick.

The migration utility rolls back changes if anything goes wrong, is covered by our test suite and has proved itself with manual testing.

Custom Field Types in Nodes

Previously, node authors had to use built-in field types for inputs and outputs of their nodes. While this covered many use-cases, we recognized the need for “custom” field types. This is now fully supported, and any pydantic model can be used as a field type.

💿 Installation and Upgrading:

To install version 3.5.0, please download the zip file at the bottom of the release notes (under “Assets”), unpack it, and then double-click to launch the script install.sh (Macintosh, Linux) or install.bat (Windows). Alternatively, you can open a command-line window and execute the installation script directly.

If you already have InvokeAI version 3.x installed, you can update by running invoke.sh / invoke.bat and selecting “Updated InvokeAI” to upgrade, or you can download and run the installer in your existing InvokeAI installation location.

🚨 Please ensure your generation queue has no pending items before upgrading. Pending generations may fail after an upgrade. 🚨

Download the installer: InvokeAI-installer-v3.5.0.zip

💻 Developer Changes

There are a number of important changes for contributors in this release.

Frontend/UI

The biggest change is that the frontend build is no longer included in main. If you run the app off a clone of the repo, you’ll need to build the frontend to use the UI. See the “Impact to Contributors” section on this PR https://github.com/invoke-ai/InvokeAI/pull/5253.

Other changes:

  • Moved from yarn to pnpm for package management
  • Updated many packages
  • Refactored all workflow schemas and types
  • Workflow migration logic implemented
  • Changes to release process

Backend Changes

This release includes feature-flagged changes to the model manager and a new database migration utility.

Model Manager

The Model Manager is partway through a redesign, to make it more capable and maintainable. The redesign will support a much better user experience for downloading, installing and managing models. The changes are in the repo, but implemented separately from the user-facing app.

InvokeAI v3.2.0

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 and also serves as the foundation for multiple commercial products.

To learn more about InvokeAI, please see our Documentation or join the Discord!

What’s New in 3.2.0:

  • Queueing
    • This is a powerful new feature that allows you to queue multiple image generations, create batches, manage the queue, and gain insight into generations.
  • IP-Adapter is now supported
    • Instructions on getting started with IP-Adapter are located in the “Things to Know” section below
  • TAESD is now supported. You can download TAESD or TAESDXL through the model manager UI
  • LoRAs and ControlNets are now able to be recalled with the “Use All” function
  • New nodes! Load prompts from a file, string manipulation, and expanded math functions
  • Node caching - improve performance by using previously cached generation values
  • V-prediction for SD1.5 is now supported
  • Importing images from previous versions of InvokeAI has been fixed
  • Database maintenance script can be run with invokeai-db-maintenance
  • View image metadata with the invokeai-metadata command
  • Workflow Editor UI/UX improvements
  • Unified Canvas improvements & bug fixes

Things to Know:

  • If you experience the server error, TypeError: Invoker.create_execution_state() got an unexpected keyword argument 'queue_id', try clearing your local browser cache or resetting the InvokAI UI (Settings -> Reset UI) before running a generation.

  • You might see a red alert icon on your nodes after loading a workflow. This indicates that the node in the workflow is from an older version of InvokeAI, or the node doesn’t have a version. If your workflow runs, you may safely ignore this, and we will add functionality to “upgrade” the un-versioned nodes in a future update. If the workflow does not work, you will need to delete and add the nodes.

  • To get started with IP-Adapter, you’ll need to download the image encoder and IP-Adapter for the desired based model. Once the models are installed, IP-Adapter is able to be used under the “Control Adapters” options.

    Image Encoders:

    IP-Adapter Models:

    These can be installed from the Model Manager by choosing “Import Models” and pasting in the repoIDs of the desired model. Remember to install the model and the image encoder! For example to get started with IP-Adapter for SD1.5 these are the repo IDs:

    • InvokeAI/ip_adapter_plus_sd15
    • InvokeAI/ip_adapter_sd_image_encoder

    or from the command line by starting the “Developer’s Console” from the invoke.bat launcher and pasting this command:

    invokeai-model-install --add InvokeAI/ip_adapter_sd_image_encoder InvokeAI/ip_adapter_sdxl_image_encoder InvokeAI/ip_adapter_sd15 InvokeAI/ip_adapter_plus_sd15 InvokeAI/ip_adapter_plus_face_sd15 InvokeAI/ip_adapter_sdxl

Installation and Upgrading:

To install v3.2.0, please download the zip file at the bottom of the release notes (under “Assets”), unpack it, and then double-click to launch the script install.sh (Macintosh, Linux) or install.bat (Windows). Alternatively, you can open a command-line window and execute the installation script directly.

What’s New in v3.1.0

Workflows

InvokeAI 3.1.0 introduces a new powerful tool to aide the image generation process in the Workflow Builder. Workflows combine the power of nodes-based software with the ease of use of a GUI to deliver the best of both worlds.

The Node Editor allows you to build the custom image generation workflows you need, as well as enables you to create and use custom nodes, making InvokeAI a fully extensible platform.

To get started with nodes in InvokeAI, take a look at our example workflows, or some of the custom Community Nodes.

A zip file of example workflows can be found at the bottom of this page under Assets.

Other New Features

  • Expanded SDXL support across all areas of InvokeAI.
  • Enhanced In-painting & Out-painting capabilities.
  • Improved Control Asset Usage, including from the Unified Canvas.
  • Newly added nodes for better functionality.
  • Seamless Tiling is back, with SDXL support!
  • Improved In-inpainting & Out-painting
  • Generation statistics can be viewed from the command line after generation
  • Hot-reloading is now available for python files in the application
  • LoRAs are sorted alphabetically
  • Symbolic links to directories in the autoimport folder are now supported
  • UI/UX Improvements
  • Interactively configure image generation options, the attention system, and the VRAM cache
  • …and so much more! You can view the full change log here

Installation / Upgrading

Installing using the InvokeAI zip file installer

To install v3.1.0 please download the zip file at the bottom of the release notes (under “Assets”), unpack it, and then double-click to launch the script install.sh (Macintosh, Linux) or install.bat (Windows). Alternatively, you can open a command-line window and execute the installation script directly.

If you have InvokeAI 2.3.5 or older installed, we recommend that you install into a new directory, such as invokeai-3 instead of the previously-used invokeai directory. We provide a script that will let you migrate your old models and settings into the new directory, described below.

In the event of an aborted install that has left the invokeai directory unusable, you may be able to recover it by asking the installer to install on top of the existing directory. This is a non-destructive operation that will not affect existing models or images.

All users can upgrade from 3.0.2 using the launcher’s “upgrade” facility. If you are on a Linux or Macintosh, you may also upgrade a 2.3.2 or higher version of InvokeAI to 3.1 using this recipe, but upgrading from 2.3 will not work on Windows due to a 2.3.5 bug (see workaround below):

  1. Enter the root directory you wish to upgrade
  2. Launch invoke.sh or invoke.bat
  3. Select the upgrade menu option [9]
  4. Select “Manually enter the tag name for the version you wish to update to” option [3]
  5. Select option [1] to upgrade to the latest version.
  6. When the upgrade is complete, the main menu will reappear. Choose “rerun the configure script to fix a broken install” option [7]

Windows users can instead follow this recipe:

  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/v3.1.0.zip" --use-pep517 --upgrade
invokeai-configure --root .

This will produce a working 3.1.0 directory. You may now launch the WebUI in the usual way, by selecting option [1] from the launcher script

After you have confirmed everything is working, you may remove the following backup directories and files:

  • invokeai.init.orig
  • models.orig
  • configs/models.yaml.orig
  • embeddings
  • loras

To get back to a working 2.3 directory, rename all the ‘*.orig” files and directories to their original names (without the .orig), run the update script again, and select [1] “Update to the latest official release”.

Note:

  • If you had issues with inpainting on a previous InvokeAI 3.0 version, delete your models/.cache folder before proceeding.

What to do if problems occur during the install

Due to the large number of Python libraries that InvokeAI requires, as well as the large size of the newer SDXL models, you may experience glitches during the install process. This particularly affects Windows users. Please see the Installation Troubleshooting Guide for solutions.

In the event that an update makes your environment unusable, you may use the zip installer to reinstall on top of your existing root directory. Models and generated images already in the directory will not be affected.

Migrating images from a 2.3 InvokeAI root directory to a 3.0 directory

We provide a script, invokeai-import-images, which will copy images from any previous version of InvokeAI to a new 3.0 directory. To run it, execute the launcher and select option [8] “Developer’s console”. This will take you to a new command line interface. On the command line, type:

invokeai-import-images

This will prompt you to select the destination and source directories, and allow you to select which image gallery board to import into.

Migrating models and settings from an old InvokeAI root directory to a 3.0 directory

We provide a script, invokeai-migrate3, which will copy your models and settings from a 2.3-format root directory to a new 3.0 directory. To run it, execute the launcher and select option [8] “Developer’s console”. This will take you to a new command line interface. On the command line, type:

invokeai-migrate3 --from <path to 2.3 directory> --to <path to 3.0 directory>

Provide the old and new directory names with the --from and --to arguments respectively. This will migrate your models as well as the settings inside invokeai.init. You may provide the same --from and --to directories in order ot upgrade a 2.3 root directory in place. (The original models and configuration files will be backed up.)

Upgrading using pip

Developers and power users can upgrade to the current version by activating the InvokeAI environment and then using:

pip install --use-pep517 --upgrade InvokeAI
invokeai-configure --yes --skip-sd-weights

You may specify a particular version by adding the version number to the command, as in:

pip install --use-pep517 --upgrade  InvokeAI==3.1.0
invokeai-configure --yes --skip-sd-weights

Important: After doing the pip install, it is necessary to invokeai-configure in order to download new core models needed to load and convert Stable Diffusion XL .safetensors files. The web server will refuse to start if you do not do so.

Getting Started with SDXL

Stable Diffusion XL (SDXL) is the latest generation of StabilityAI’s image generation models, capable of producing high quality 1024x1024 photorealistic images as well as many other visual styles. SDXL comes with two models, a “base” model that generates the initial image, and a “refiner” model that takes the initial image and improves on it in an img2img manner. In many cases, just the base model will give satisfactory results.

To download the base and refiner SDXL models, you have several options:

  1. Select option [5] from the invoke.bat launcher script, and select the base model, and optionally the refiner, from the checkbox list of “starter” models.
  2. Use the Web’s Model Manager to select “Import Models” and when prompted provide the HuggingFace repo_ids for the two models:
    • stabilityai/stable-diffusion-xl-base-1.0
    • stabilityai/stable-diffusion-xl-refiner-1.0
  3. Download the models manually and cut and paste their paths into the Location field in “Import Models”

Also be aware that SDXL requires at 6-8 GB of VRAM in order to render 1024x1024 images and a minimum of 16 GB of RAM. For best performance, we recommend the following settings in invokeai.yaml:

precision: float16
ram: 12.0
vram: 0.5

Known Issues in 3.1

This is a list of known issues in 3.1.0 as well as features that are planned for inclusion in later releases:

  • The max_vram_cache and ram_cache settings in invokeai.yaml have been deprecated and renamed to vram and ram. To adjust cache size, we recommend using the configure script (option [6] in the launcher) to adjust them.
  • Variation generation was not fully functional and did not make it into the release.
  • High-res optimization has been removed from the basic user interface as we experiment with better ways to achieve good results with nodes. However, you will find a high-res optimization workflows attached and in the Community Nodes Discord channel at https://discord.com/channels/1020123559063990373/1130291608097661000 for use with the Workflow tool.
