Node-based visual AI studio for images, video, 3D and audio
Connect models, samplers, conditioning, LoRAs and output nodes on an infinite canvas where every step is visible and adjustable.
One interface for image generation, video, 3D assets and audio or music workflows, with support for leading open and partner models.
Run ComfyUI locally on your own GPU, or open the same workflows in the cloud when you don't have the hardware.
Deploy any workflow as a production API so your own app or agent can generate outputs on demand.
Open generative models for image, video, audio, and 3D
Generate and edit high-quality images for marketing, product visuals, and creative work, using the model family that made Stable Diffusion widely known.
Create and edit video, including 3D and 4D video models designed for immersive worlds in gaming and entertainment.
Work with the Stable Audio model family for music, soundscapes, and sound effects, with open-weight releases trained on licensed data.
Integrate production-ready media generation into your own products via a hosted API, with no infrastructure to manage.
