MiniMax-H3 is MiniMax's omni-modal video generation model (the Hailuo 3 generation), released July 31, 2026. It reads text, image, video and audio references as one unified context and generates 4-15 second videos at 768P or 2K with native stereo audio. Billed per second of generated output: $0.08/s at 768P, $0.13/s at 2K.

Duration: 4-15 seconds, integer values. Resolution: 768P or 2K. Aspect ratios: adaptive (default), 21:9, 16:9, 4:3, 1:1, 3:4, 9:16. Prompt: up to 7000 characters. References: images (first/last frame or subject), one video, one audio track. Output: video with native stereo audio.
Billed per second of generated video rather than per request: $0.08 per second at 768P, $0.13 per second at 2K — a 10-second 2K clip is $1.30. Input materials are metered on top: 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. The final charge settles from the task's actual usage when it completes.
Generation is an asynchronous task API. Submit with POST /v1/video/generations (model minimax/minimax-h3, prompt, optional duration/size/metadata references), poll GET /v1/video/generations/{task_id}, then download the finished clip from the returned URL.
