ComfyUI

The most powerful and modular AI engine for content creation.

ComfyUI is the AI creation engine for visual professionals who demand control over every model, every parameter, and every output. Its powerful and modular node graph interface empowers creatives to generate images, videos, 3D models, audio, and more... - ComfyUI natively supports the latest open-source state of the art models. - API nodes provide access to the best closed source models such as Nano Banana, Seedance, Hunyuan3D, etc. - It is available on Windows, Linux, and macOS, locally with our desktop application, our portable install or on our cloud. - The most sophisticated workflows can be exposed through a simple UI thanks to App Mode. - It integrates seamlessly into production pipelines with our API endpoints.

• Many optimizations: Only re-executes the parts of the workflow that changes between executions.
• Smart memory management: can automatically run large models on GPUs with as low as 1GB vram with smart offloading.
• Works even if you don't have a GPU with: --cpu (slow)
• Can load ckpt and safetensors: All in one checkpoints or standalone diffusion models, VAEs and CLIP models.
• Safe loading of ckpt, pt, pth, etc.. files.
• Embeddings/Textual inversion
• Loras (regular, locon and loha)
• Hypernetworks
• Loading full workflows (with seeds) from generated PNG, WebP and FLAC files.
• Saving/Loading workflows as Json files.
• Nodes interface can be used to create complex workflows like one for Hires fix or much more advanced ones.
• Area Composition
• Inpainting with both regular and inpainting models.
• ControlNet and T2I-Adapter
• Upscale Models (ESRGAN, ESRGAN variants, SwinIR, Swin2SR, etc...)
• GLIGEN
• Model Merging
• LCM models and Loras
• Latent previews with TAESD
• Works fully offline: core will never download anything unless you want to.
• Optional API nodes to use paid models from external providers through the online Comfy API disable with: --disable-api-nodes
• Config file to set the search paths for models.

Release Process

ComfyUI follows a weekly release cycle targeting Monday but this regularly changes because of model releases or large changes to the codebase. There are three interconnected repositories:

1. ComfyUI Core
2. Releases a new major stable version (e.g., v0.7.0) roughly every 2 weeks.
3. Starting from v0.4.0 patch versions will be used for fixes backported onto the current stable release.
4. Minor versions will be used for releases off the master branch.
5. Patch versions may still be used for releases on the master branch in cases where a backport would not make sense.
6. Commits outside of the stable release tags may be very unstable and break many custom nodes.

7. Serves as the foundation for the desktop release

8. Comfy Desktop

9. Builds a new release using the latest stable core version

10. ComfyUI Frontend

11. Every 2+ weeks frontend updates are merged into the core repository
12. Features are frozen for the upcoming core release
13. Development continues for the next release cycle
