MiniMax H3 Max is a hosted, post-trained video model built on top of MiniMax's open-weights MiniMax H3. It is an independent browser workspace, not a MiniMax official product, and the Max weights are not public. The site's core claim is speed: a published demo generated a 15-second clip in about 5 seconds.
Key Features

- Prompt follow: Tuned for stronger adherence to detailed briefs than the base MiniMax H3 model.
- Hosted access: Runs in the browser with no desktop app; sign in with Google, no API key required.
