About Invoke AI

Invoke is an open-source creative engine for Stable Diffusion and related image models. It runs a locally hosted web server with a React-based user interface for generating, refining, and iterating on images. The homepage describes it as free to use under a commercially friendly license and says it serves as the foundation for multiple commercial products. Pricing information is not listed beyond that license description.

The main tools are a unified canvas that supports in- and out-painting and brush tools, a node-based workflow system for building and sharing generation pipelines, and a gallery that keeps image metadata so prompts and settings can be recalled. The model list covers SD 1.5 through SD 3.5, SDXL, several Flux variants, and other models. Some models, including Nano Banana, GPT Image, and Wan, are listed as API-only. Installation requires compatible hardware, and support for gguf models is limited to some formats.
