Overview

What is MiniMax-H3?

MiniMax-H3 is an open video model that generates video and stereo audio together, hosted on Mage's GPUs. Mage runs it as MiniMax-H3 Turbo, the default, and the base MiniMax-H3, which makes shorter clips.

It takes a first and a last frame, or saved Characters with their voices, reference images, and reference videos.

Strengths

What MiniMax-H3 does best

Best at

  • Video with sound generated alongside it
  • Long clips at a low price on MiniMax-H3 Turbo
  • Character video with a consistent voice
  • Street, music, and crowd scenes where audio matters

Trade-offs

  • One clip uses frames or references, not both
  • References share a time budget with the clip, so many references mean a shorter clip
  • Tops out at 768p
