Comfy-Org/ComfyUI

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. Partner 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. Get Started Local Desktop Application The easiest way to get started. Available on Windows & macOS. Manual Install Supports all operating systems and GPU types (NVIDIA, AMD, Intel, Apple Silicon, Ascend). Cloud Comfy Cloud Our official paid cloud version for those who can't afford local hardware. Examples See what ComfyUI can do with the newer template workflows or old example workflows . Features A visual node graph for building and reusing image, video, audio, 3D, and text workflows without code. Reusable subgraphs, workflow templates, App Mode, and a local API for integrating workflows into applications. Efficient local execution with asynchronous queueing, partial graph re-execution, smart VRAM and RAM management, model offloading, and support for quantized models. Broad native model support. This is a representative list; browse the workflow library for maintained, ready-to-run templates.

Load complete checkpoints or separate diffusion models, VAEs, text encoders, LoRAs, ControlNets, adapters, and upscalers from supported model formats. Built-in tools for inpainting, outpainting, reference conditioning, masks and compositing, model merging, upscaling, frame interpolation, segmentation, depth estimation, and media processing. Save and load workflows as JSON, or recover complete workflows and seeds from supported generated media. Runs fully offline: core does not download anything unless you request it. Use --disable-api-nodes to disable the optional paid Comfy API nodes and force all built-in functionality to stay offline. Extend ComfyUI with custom nodes Configure additional model locations with extra_model_paths.yaml . Support for saving and loading high bit depth images and videos: 16 bit PNG images, 32 bit EXR, 10 bit AVIF are supported and more. Support for saving and loading HDR videos and images in various formats. 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: ComfyUI Core Releases a new major stable version (e.g., v0.7.0) roughly every 2 weeks. Starting from v0.4.0 patch versions will be used for fixes backported onto the current stable release. Minor versions will be used for releases off the master branch. Patch versions may still be used for releases on the master branch in cases where a backport would not make sense. Commits outside of the stable release tags may be very unstable and break many custom nodes. Serves as the foundation for the desktop release Comfy Desktop Builds a new release using the latest stable core version ComfyUI Frontend Every 2+ weeks frontend updates are merged into the core repository Features are frozen for the upcoming core release Development continues for the next release cycle Shortcuts Keybind Explanation Ctrl + Enter Queue up current graph for generation Ctrl + Shift + Enter Queue up current graph as first for generation Ctrl + Alt + Enter Cancel current generation Ctrl + Z / Ctrl + Y Undo/Redo Ctrl + S Save workflow Ctrl + O Load workflow Ctrl + A Select all nodes Alt + C Collapse/uncollapse selected nodes Ctrl + M Mute/unmute selected nodes Ctrl + B Bypass selected nodes (acts like the node was removed from the graph and the wires reconnected through) Delete / Backspace Delete selected nodes Ctrl + Backspace Delete the current graph Space Move the canvas around when held and moving the cursor Ctrl / Shift + Click Add clicked node to selection Ctrl + C / Ctrl + V Copy and paste selected nodes (without maintaining connections to outputs of unselected nodes) Ctrl + C / Ctrl + Shift + V Copy and paste selected nodes (maintaining connections from outputs of unselected nodes to inputs of pasted nodes) Shift + Drag Move multiple selected nodes at the same time Ctrl + D Load default graph Alt + + Canvas Zoom in Alt + - Canvas Zoom out Ctrl + Shift + LMB + Vertical drag Canvas Zoom in/out P Pin/Unpin selected nodes Ctrl + G Group selected nodes Q Toggle visibility of the queue H Toggle visibility of history R Refresh graph F Show/Hide menu .

Windows Portable There is a portable standalone build for Windows that should work for running on Nvidia GPUs or for running on your CPU only. It is not recommended for regular users. Regular users should use the desktop app above. Direct link to download (nvidia) Simply download, extract with 7-Zip or with the windows explorer on recent windows versions and run. For smaller models you normally only need to put the checkpoints (the huge ckpt/safetensors files) in: ComfyUI\models\checkpoints but many of the larger models have multiple files. Make sure to follow the instructions to know which subfolder to put them in ComfyUI\models\ If you have trouble extracting it, right click the file -> properties -> unblock The portable above currently comes with python 3.13 and pytorch cuda 13.0. Update your Nvidia drivers if it doesn't start. All Official Portable Downloads: Portable for AMD GPUs Portable for Intel GPUs Portable for Nvidia GPUs (supports 20 series and above). Portable for Nvidia GPUs with pytorch cuda 12.6 and python 3.12 (Supports Nvidia 10 series and older GPUs, DO NOT USE THIS ON NEWER 20 SERIES AND ABOVE GPUS). How do I share models between another UI and ComfyUI? See the Config file to set the search paths for models. In the standalone windows build you can find this file in the ComfyUI directory. Rename this file to extra_model_paths.yaml and edit it with your favorite text editor. comfy-cli You can install and start ComfyUI using comfy-cli: pip install comfy-cli comfy install Manual Install (Windows, Linux) Python 3.14 works but some custom nodes may have issues. The free threaded variant works but some dependencies will enable the GIL so it's not fully supported. Python 3.13 is very well supported.
