MiniMax officially releases MiniMax H3
MiniMax officially releases MiniMax H3 on July 31, 2026, and opens the H3-Base weights on August 3.
What happened
Event details
MiniMax H3 is an audiovisual generation system that accepts a context composed of text, images, video and audio, and can generate videos up to 15 seconds at 2K with native stereo audio. The official repository provides two H3-Base checkpoints and deployment materials, while the full 2K workflow still relies on hosted modules.
Assessment
Why it matters
The model unifies text, image, video and audio context for audiovisual generation and publishes H3-Base weights and deployment materials, giving it high technical and ecosystem impact. Hosted modules and usage restrictions remain, so its openness and long-term impact are assessed cautiously.
Availability
Access notes
Available through the MiniMax API and apps. The public weights do not include H3-Context-IR or H3-Regenerate-2K.
