Full pricing →02How it runs
A private endpoint, not a shared API.
Launching MiniMax H3 runs the model on your own instance and gives you a private /v1 video endpoint and API key. Post a prompt (plus optional reference images, clips, or audio) as multipart form data to /v1/videos/sync and get back an MP4 with stereo audio; /v1/videos is the async job-polling variant. The endpoint is yours alone — terminate the instance and it goes away with it.
Billing is by the second on the 4× 141 GB shape the launcher enforces, from boot to terminate. No commitment and no tier gates.
