Overview

Grounded in available product and source data

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.

Features

Nodes/graph/flowchart interface to experiment and create complex Stable Diffusion workflows without needing to code anything.
NOTE: There are many more models supported than the list below, if you want to see what is supported see our templates list inside ComfyUI.
Image Models
- SD1.x, SD2.x (unCLIP)
- SDXL, SDXL Turbo
- Stable Cascade
- SD3 and SD3.5
- Pixart Alpha and Sigma
- AuraFlow
- HunyuanDiT
- Flux
- Lumina Image 2.0
- HiDream
- Qwen Image
- Hunyuan Image 2.1
- Flux 2
- Z Image

- Wan 2.1
- Wan 2.2
- Hunyuan Video 1.5
Audio Models
- Stable Audio
- ACE Step
3D Models
- Hunyuan3D 2.0
Asynchronous Queue system
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.

Workflow examples can be found on the Examples page

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

Installing

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 on the releases page.

Direct link to download

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.
