In their own words
InvokeAI
InvokeAI is a free, open-source creative engine for AI image generation. It runs on Linux, macOS, and Windows, or through self-hosted and API setups. A layer-based canvas supports drawing, painting, sketching, and image editing, while a visual node editor builds repeatable workflows. Listed model support includes Flux, SDXL, and SD 1.5, with Model Manager handling checkpoints, LoRAs, Textual Inversions, and ControlNets. Tools include ControlNet guidance, batch generation, prompt wildcards, and high-resolution upscaling. InvokeAI supports text-to-image generation, reference images, API access, and PNG output. External integrations include Google Gemini, OpenAI, BytePlus Seedream, and Alibaba Cloud DashScope; those providers bill usage separately. Local operation keeps data, prompts, and creations under the user's control. The former hosted Invoke.ai platform has shut down.
