:octicons-log-16: Important Changes Since Version 2.3
Nodes
Behind the scenes, InvokeAI has been completely rewritten to support "nodes," small unitary operations that can be combined into graphs to form arbitrary workflows. For example, there is a prompt node that processes the prompt string and feeds it to a text2latent node that generates a latent image. The latents are then fed to a latent2image node that translates the latent image into a PNG.
The WebGUI has a node editor that allows you to graphically design and execute custom node graphs. The ability to save and load graphs is still a work in progress, but coming soon.
Command-Line Interface Retired
All "invokeai" command-line interfaces have been retired as of version 3.4.
To launch the Web GUI from the command-line, use the command
invokeai-web rather than the traditional invokeai --web.
ControlNet
This version of InvokeAI features ControlNet, a system that allows you to achieve exact poses for human and animal figures by providing a model to follow. Full details are found in ControlNet
