MiniMax launches H3 video model with open weights, undercutting rivals on price
Chinese startup MiniMax released H3, a video-generation model that processes text, images, video and audio, generating clips up to 15 seconds in 2K resolution with native stereo sound.
H3 can edit existing footage and transfer motion from one video to another using instructions or reference material in different formats.
MiniMax plans to release H3's model weights within days, extending China's open-weight approach into video generation, an area where most leading models stay proprietary.
MiniMax says generating 2K video with H3 costs less than one-third of mainstream rival products, and the model is built to run on several Chinese-made chips as part of a push away from U.S. semiconductors.
The launch intensifies competition among Chinese video-model makers following ByteDance's Seedance 2.0 and Kuaishou's Kling 3.0; MiniMax is also reportedly developing a 2.7-trillion-parameter language model.
