MiniMax Releases Open-Source Omni-modal Model H3 with Native 2K Stereo Video
MiniMax has officially released the omni-modal generation system MiniMax-H3. The 33B parameter model features open weights on Hugging Face and is adapted for 🧨 Diffusers. It unifies multimodal context across text, image, video, and audio, supporting diverse inputs like text-to-video, image-to-video, and reference-image-to-video. Users can even combine video, image, text, and audio as reference materials in a single generation. For outputs, H3 natively generates end-to-end videos up to 2K resolution and 15 seconds long with native stereo sound, eliminating the need for post-dubbing.
Confirmed
- Model Specs & Open Source: MiniMax-H3 has 33B parameters. Its weights are publicly available on Hugging Face, adapted for 🧨 Diffusers, with deployment solutions jointly launched by the vLLM project and MiniMax.
- Generation Capabilities: Supports generating videos up to 2K resolution and 15 seconds long. It natively supports text/image-to-audio, achieving synchronized audio and video generation.
- Leaderboard Performance: According to @NerdyRodent, H3 ranks first on the Artificial Analysis video editing leaderboard and second on the text-to-video leaderboard.
Why it matters
- Audio-Visual Integration: H3 achieves coherent end-to-end generation of audio-visual content without post-dubbing, significantly lowering the barrier and complexity of video creation.
- Open Source Ecosystem: As a rare and powerful open-source video model, H3 offers open weights and actively adapts to mainstream inference tools, providing the community with a highly competitive multimodal foundational solution.
