Direct answer
What is MiniMax H3?
MiniMax H3 is the newest video model from MiniMax, the maker of Hailuo. MiniMax calls it a general-purpose multimodal generation model: one model makes video from text, from a photo (a first frame, or a first and a last frame) and from reference images, videos and audio. One clip runs 4 to 15 seconds at 768p or 2K.
MiniMax published it on July 31, 2026. Its launch post says H3 makes video with native stereo sound and builds 2K from the same pass instead of a separate upscaling step.

Use it when
Who MiniMax H3 is for
You want a 2K clip of up to 15 seconds with its sound in one take: a fashion walk, a product scene with a person in it, an ad opener.
You have pictures, clips or a voice to steer it: a face, an outfit or a sound can be given as a reference instead of described. On Reviral 768p and 2K cost the same 17.2 credits a second.
