MiniMax H3 Highspeed

MiniMax H3 Highspeed is a faster version of minimax/h3, the multimodal video model from MiniMax. It balances quality and speed, which makes it a good fit for everyday content creation where you don’t need 2K output.

What it does

• Text-to-video: describe a scene and get a video back.
• Image-to-video: give it a first frame, a last frame, or both, to control how the video starts and ends.
• Reference generation: give it reference images, videos, or audio to guide the character, motion, camera, style, voice, or editing rhythm.

Videos can be 4 to 15 seconds long, at 768P.
