Straight answers about using the MiniMax H3 model inside ComfyUI and getting the most from your setup.
What does the comfyui minimax h3 workflow do?
It is ComfyUI's native integration of MiniMax H3, MiniMax's general-purpose omni-modal generation model released as open weights. The flow creates video with native stereo audio from text, images, video, and audio references in a single forward pass.
