MiniMax H3 Model Announced with Open-Source Weights and Early Tests

MiniMax has officially announced the upcoming release of its next-generation model, H3, confirming that the model weights will be open-sourced soon. Early tests indicate exceptional performance in video generation and multimodal understanding, sparking intense interest and discussion within the community.

已确认

• MiniMax revealed on Hugging Face that the H3 model is coming soon and its weights will be open-sourced shortly.
• The official account showcased actual generation results using the H3 model on the Hailuo AI platform, stunning the community.
• Information regarding the MiniMax M3 model was also disclosed, highlighting its capabilities in sparse attention and mathematical proof generation.

尚未确认

• Video model specs: According to early feedback, the H3 video model supports a native resolution of 2560 × 1440 (2K) and can generate videos up to 15 seconds long, entirely raw output without post-editing.
• Native multimodal capabilities: Developer tests suggest H3 focuses on native multimodal understanding, allowing users to freely combine up to 12 reference materials (mixing video, text, image, and audio).
• Generation quality: Testers generated cinematic visuals using minimalist prompts, with stunning performances in anime-style animation generation.

为什么重要

• If H3 can run locally in environments like ComfyUI using an RTX 3060 level GPU, it will greatly benefit developers with limited compute power and lower technical barriers.
• Its robust multimodal mixed-input capability is regarded as a major step toward rivaling industry frontiers in the multimodal domain.
