ComfyUI is a versatile and modular GUI and backend for Stable Diffusion, enabling users to create and run complex Stable Diffusion pipelines through a graph/nodes/flowchart-based interface. It fully supports a range of models, including SD1.x, SD2.x, SDXL, Stable Video Diffusion, Stable Cascade, and SD3. The system features an asynchronous queue that optimizes performance by only re-executing parts of the workflow that change between runs.
This platform offers extensive functionality, accommodating various model formats such as ckpt, safetensors, and diffusers checkpoints. It supports standalone VAEs and CLIP models, embeddings/textual inversion, loras, hypernetworks, and area composition. Additionally, ComfyUI includes inpainting, ControlNet, T2I-Adapter, upscale models, unCLIP models, GLIGEN, model merging, LCM models, SDXL Turbo, and latent previews with TAESD.
ComfyUI is designed for efficiency, starting up quickly and functioning entirely offline. Users can easily configure model search paths through a config file, enhancing customization and ease of use. With its robust set of features and optimization capabilities, ComfyUI is a powerful tool for designing advanced Stable Diffusion workflows.
