FAQ

How is MiniMax-H3 billed?
Per second of generated video: $0.08 per second at 768P and $0.13 per second at 2K, for the duration you declare (4-15 seconds, integers). Input materials add to that: audio references are free, images beyond the first five cost $0.04 each, and a reference video is billed by its own duration at the same per-second rate.
How do I call MiniMax-H3?
Submit a task with POST /v1/video/generations using model minimax/minimax-h3, a prompt, and optionally duration (4-15), size (768P or 2K) and reference inputs via metadata. Poll GET /v1/video/generations/{task_id} until it succeeds, then download the video from the returned URL.
What inputs does it accept?
A text prompt (required, up to 7000 characters), plus optional image references (including first/last frame), a reference video, and a reference audio track.
What does it output?
A single video of 4 to 15 seconds at 768P or 2K, with stereo audio generated natively alongside the visuals — no separate audio pass needed.
