Comfy and MiniMax are running a two-week H3 Sync Challenge (Aug 20–Sep 1): create a piece up to 90 seconds where sound and motion are inseparable, built mainly in ComfyUI with H3. Winners announced via livestream on Sep 2.
Prizes (four ways to win):
- Best Overall: RTX 5090
- Best Creative / Best Technical / Built with MCP: RTX 5060 Ti each
Judging covers audio-sync realism, creative execution, workflow quality (annotated, replicable), and community value; the MCP track requires an agent to meaningfully drive the process via Comfy MCP. Free to enter with Comfy Local or Comfy Cloud (5 free runs for new users, no credit card).
