ComfyUI

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. Desktop Application The easiest way to get started. Available on Windows & macOS. Windows Portable Package Get the latest commits and completely portable. Available on Windows. Manual Install Supports all operating systems and GPU types (NVIDIA, AMD, Intel, Apple Silicon, Ascend). 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. 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 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 2. Comfy Desktop Builds a new release using the latest stable core version 3. 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 There is a portable standalone build for Windows that should work for running on Nvidia GPUs or for running on your CPU only on the releases page. 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 The portable above currently comes with python 3.13 and pytorch cuda 13.0. Update your Nvidia drivers if it doesn't start. Portable for Nvidia GPUs with pytorch cuda 12.6 and python 3.12 (Supports Nvidia 10 series and older GPUs). 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. If you have trouble with some custom node dependencies on 3.13 you can try 3.12 torch 2.5 is minimally supported but using a newer version is extremely recommended. Some features and optimizations might only work on newer versions. We generally recommend using the latest major version of pytorch with the latest cuda version unless it is less than 2 weeks old. If your pytorch is more than 6 months old, please update it. This is the command to install the nightly with ROCm 7.2 which might have some performance improvements: AMD GPUs (Experimental: Windows and Linux), RDNA 3, 3.5 and 4 only. These have less hardware support than the builds above but they work on windows. You also need to install the pytorch version specific to your hardware. Intel Arc GPU users can install native PyTorch with torch.xpu support using pip. More information can be found here This is the command to
