ComfyUI (Core Repository)
The core open-source ComfyUI engine — a modular node-based interface for generating images, video, 3D, and audio using diffusion models.
ComfyUI is the core open-source node-based engine for generative AI, developed by Comfy Org. It provides a modular graph interface where users can build custom pipelines by connecting nodes for model loading, sampling, image processing, video generation, 3D creation, and audio production.
The repository is the primary development hub for the ComfyUI ecosystem, with contributions from the community and active daily development by the core team. It supports a vast library of custom nodes via the ComfyUI-Manager and the official Registry.
