ComfyUI

概述

ComfyUI is an open-source, node-based interface for building and running image and video generation workflows with diffusion models such as Stable Diffusion and Flux. Users compose pipelines visually from nodes, save and share workflow graphs, and extend the system with a large ecosystem of custom nodes. The software is free and runs locally, with optional paid API access to hosted frontier models.
