MiniMax H3 weights ship with native ComfyUI nodes on day zero

MiniMax H3 arrived with native support in ComfyUI, the visual workflow application for generative models. Its launch workflows let users connect prompts and reference inputs to video generation. One concrete control is to supply an opening frame, a closing frame or both, then have the model generate the intervening video.

The integration guide supplies downloadable workflows and model-placement instructions. That gives users an existing workflow to adapt when trying the released weights, rather than requiring them to assemble the integration themselves.
