ComfyUI raises $30M at $500M valuation, giving creators manual control over AI-generated images, videos, and audio

ComfyUI, a startup building AI creation tools, closed a $30 million funding round that values the company at $500 million. The platform lets creators adjust every step of how AI generates media — instead of typing a prompt and accepting the output, users can tweak the underlying AI models, settings, and workflow in real time.

Unlike black-box AI tools where you input a prompt and get back an image, ComfyUI shows the entire 'recipe' behind the AI's output (the mathematical instructions that shape each pixel). Creators can swap in different AI models, change quality settings, or chain multiple AI steps together — giving them the same level of control a film director has over lighting and camera angles.

This matters to digital creators, video producers, and designers who found existing AI tools too limited or unpredictable — they can now fine-tune outputs to match a specific style or brand instead of waiting for an AI to guess their intent. It also appeals to studios and agencies building custom AI workflows for clients, since they can now build tools tailored to their exact needs rather than relying on closed platforms.
