MiniMax H3 Day-0 Support in ComfyUI: Open Weights, Native Audio, and 2K Video

MiniMax released its third-generation video model, H3, with open weights and native stereo audio support. Integrated into ComfyUI, H3 generates up to 2K resolution videos up to 15 seconds long from text, images, video, or audio inputs. Optimizations reduce memory use by 66%, enabling local runs on GPUs like the RTX 3060.
