MiniMax-H3 is an open video model that generates video and stereo audio together. Mage runs it as MiniMax-H3 Turbo, which runs unlimited from Pro for clips up to 15 seconds, and the base MiniMax-H3, which goes to 8 seconds. Both take Characters, References, Character Voices, audio and video references, and video LoRAs.

Overview

Unlimited generation by plan

Limitations

  • Frame mode and reference mode are separate on this model: one generation uses a first or last frame, or Characters and References, not both.
  • References share a 21 second budget with the clip: each reference image counts as 2 seconds and each reference video as its own length.
  • Up to 2 LoRAs, and only 1 on longer clips. Two LoRAs move a run to Max.
