MiniMax H3, a cutting-edge open-weights video model, is now supported in ComfyUI and offers a range of innovative features for video generation, including native stereo sound and 2K resolution outputs. This third-generation model from MiniMax allows for text-to-video, image-to-video, and reference-to-video capabilities, seamlessly integrating audio and visual elements to produce up to 15-second clips. Notably, it supports multimodal context understanding, allowing users to input text, images, audio, and video, which the model interprets to create cohesive outputs. The model's architectural advancements include significant memory optimization, enabling it to run efficiently on consumer-level hardware such as an RTX 3060 GPU. These enhancements are achieved by pruning modulation weights and utilizing int8 convrot quantization, reducing the memory footprint by 66%. Users can access MiniMax H3 through ComfyUI’s latest version, where they can download various workflows and templates to begin creating content.
