What is MiniMax H3 and what is it good for?

H3 is MiniMax's video generation model with native audio, suited to controlled editing, rendering text and branding into video, and building video from several reference images.

How much does H3 cost?

$0.13 per second of output video — a 5-second clip is about $0.65. The first five reference images are free; each one after that adds $0.04.

What happens if I do not specify a duration?

Hormouz reserves credit for the longest clip the model can produce (15 seconds) and releases the difference once the job finishes. Send an explicit `duration` if you want a smaller amount reserved.

How do I access H3 from inside Iran?
