ComfyUI is the leading open-source node-based AI image, video, audio, and 3D generation platform that gives artists, developers, and researchers full visual control over every step of the AI generation pipeline through an infinitely flexible node graph interface.
Rather than presenting AI generation as a black box with simple prompt-in, image-out interactions, ComfyUI exposes every model, parameter, sampler, scheduler, and processing node as a visible, connectable element on a canvasenabling users to build, share, and reproduce complex AI workflows with complete transparency and reproducibility.
The platform supports virtually every major generative AI model released in recent years, including the full Stable Diffusion family (SD1.x, SD2.x, SDXL, SD3/3.5), Stable Cascade, Flux and Flux 2, Pixart, AuraFlow, HunyuanDiT, Lumina 2.0, HiDream, and Qwen Image for still image generation, alongside video generation models including Mochi and Hunyuan Video, audio generation models, and emerging 3D generation pipelines.
This breadth of model support means ComfyUI serves as a unified workspace for the full spectrum of generative AI media creation.
ComfyUI's node-based architecture enables workflow modularity and shareability that is impossible with prompt-based interfaces.
A complex multi-step pipelinesuch as a workflow that applies ControlNet-guided generation, upscales with a dedicated model, applies style transfer, and outputs to a specific formatcan be saved as a single workflow file, shared with the community, and reproduced by anyone with the same model checkpoints.
The Subgraph feature, introduced in 2025, allows complex node combinations to be packaged into single reusable nodes, dramatically improving workflow manageability for advanced users.
NVIDIA has partnered with ComfyUI to optimize the platform's weight streaming (RAM offload) feature, ensuring that even the largest generation models like Flux 2 with its multi-reference capability are accessible on consumer-grade GeForce RTX GPUs rather than requiring expensive professional hardware.
