MiniMax H3 Model Coming Soon with Open Weights, Video and Multimodal Capabilities Spark Buzz

MiniMax officially revealed on Hugging Face that its next-generation H3 model is coming soon, with weights to be open-sourced shortly. The official account also showcased generation results on Hailuo AI, impressing the community. Early tests indicate the H3 video model supports native 2560×1440 (2K) resolution and up to 15-second video generation, fully model-generated without post-editing. Additionally, H3 emphasizes native multimodal understanding, allowing users to freely combine up to 12 reference materials (mixing video, text, image, and audio). Community discussions highlight that if H3 can run locally in environments like ComfyUI on an RTX 3060-class GPU, it would greatly benefit developers with limited compute resources. Furthermore, MiniMax's Hugging Face page also updated information on the M3 model, showcasing its capabilities in sparse attention and mathematical proof generation.

Confirmed

• MiniMax officially stated on Hugging Face that the H3 model is coming soon and weights will be open-sourced quickly.
• The official account showcased actual generation results based on the H3 model on the Hailuo AI platform, drawing community amazement.
• Information about the MiniMax M3 model was also revealed, demonstrating its capabilities in sparse attention and mathematical proof generation.

Unconfirmed

• Video model specs: According to early hands-on feedback, the H3 video model supports native 2560×1440 (2K) resolution and up to 15-second video generation, fully model-generated without post-editing.
• Native multimodal capability: Some developers report that H3 focuses on native multimodal understanding, allowing users to freely combine up to 12 reference materials (supporting mixed video, text, image, and audio inputs).
• Generation quality: Testers generated highly cinematic visuals with minimal prompts, and anime-style animation generation was impressive.

Why it matters

• If H3 can run locally in environments like ComfyUI on an RTX 3060-class GPU, it would greatly benefit developers with limited compute resources, lowering the technical barrier.
• Its strong multimodal mixed-input capability is seen as an important step toward benchmarking against industry frontiers in the multimodal domain.
