MiniMax Releases 33B Open-Weight Multimodal Model H3 with Local Deployment

MiniMax officially released MiniMax-H3, a 33B-parameter all-round multimodal generation system, with open weights. The model supports local deployment on consumer GPUs, significantly lowering the hardware barrier for multimodal video generation, and is natively integrated into the ComfyUI ecosystem.

Confirmed

• Model parameters and deployment: MiniMax-H3 is a 33B-parameter model released with open weights, available on Hugging Face and GitHub. With dynamic memory optimization and pruning, consumer GPUs (e.g., 4070ti/5070ti) can generate videos with audio in under 2 minutes.
• Multimodal capabilities: The model natively supports unified understanding and generation of text, image, video, and audio, and can follow complex multimodal instructions. In a single generation, it can output up to 15 seconds of 2K-resolution video with native stereo audio.
• Ecosystem and skills support: ComfyUI officially announced integrated nodes for MiniMax-H3, enabling custom workflows such as Blender scene integration. Additionally, the official release includes 9 skills to assist prompt writing, covering specific video scenarios like minimalist product ads and 3D animation shorts.

Unconfirmed

• Cost comparison: According to @PrajwalTomar, the model's running cost is roughly one-third of Seedance 2.0, but this comparison is only community-reported.

Why it matters

• It lowers the barrier to multimodal video generation, allowing creators and developers to test and deploy high-quality audio-video generation workflows on local consumer hardware, while native ComfyUI support further integrates into the creative ecosystem.
