ComfyUI: A Powerful GUI for Stable Diffusion Workflows

Are you interested in creating advanced stable diffusion workflows without needing to code? Look no further than ComfyUI, a powerful and modular stable diffusion GUI and backend. With its intuitive graph/nodes/flowchart based interface, ComfyUI allows you to design and execute complex stable diffusion pipelines with ease.


ComfyUI comes with a wide range of features that make it a versatile tool for stable diffusion workflows. Here are some of its key features:

  • Nodes/Graph/Flowchart Interface: Experiment and create complex stable diffusion workflows without the need for coding.
  • Support for SD1.x, SD2.x, and SDXL: ComfyUI fully supports different versions of Stable Diffusion.
  • Asynchronous Queue System: Execute workflows efficiently with ComfyUI's asynchronous queue system.
  • Optimizations: ComfyUI only re-executes the parts of the workflow that have changed, saving time and resources.
  • Compatibility with GPUs: ComfyUI can work on GPUs with less than 3GB VRAM using the --lowvram command line option. It also works on CPUs with the --cpu option.
  • Model/Checkpoint Loading: Load ckpt, safetensors, diffusers models/checkpoints, standalone VAEs, and CLIP models.
  • Embeddings/Textual Inversion: Use embeddings and textual inversion in your workflows.
  • Wide Range of Workflow Examples: ComfyUI comes with various workflow examples, including Loras, Hypernetworks, Area Composition, Inpainting, ControlNet and T2I-Adapter, Upscale Models, unCLIP Models, GLIGEN, and Model Merging.
