Hailuo

MiniMax-H3 Reference to Video

MiniMax-H3 reference-to-video: drive generation with reference images, videos and audio. Output is 768P or 2K — 768P is the cheaper tier.

At least one ref_imgs or ref_videos item is required — audio alone is not accepted. First/last frames are not supported here; use the hailuo_h3 model for those.

Pricing — per second of generated video, in tokens (USD at $0.02/token):

resolution	tokens/s	USD/s
768P	4.95	$0.099
2K	7.15	$0.143

Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the generated video.
