ComfyUI is an extremely popular graphical user interface for Stable Diffusion that’s shared freely on Github, making it easier for users to generate images and modify their image generation models. ComfyUI_LLMVISION, the extension that was compromised to hack users, is a ComfyUI extension that allowed users to integrate large language models GPT-4 and Claude 3 into the same interface.

That is likely a small group of people. I have never used proprietary AI and never plan to do so. A feature to run these is already a stalkerware corporate hack IMO.
