MiniMax launches H3 video model with 2K resolution, open weights coming

MiniMax released its H3 video-generation model on Friday, capable of processing text, images, video and audio inputs together.
H3 generates videos up to 15 seconds at 2K resolution with native stereo sound, and can edit existing footage or transfer motion between clips.
MiniMax plans to release H3's model weights within days, extending China's open-weight approach into video generation where many top models stay proprietary.
The company 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.
H3 arrives after ByteDance's Seedance 2.0 and Kuaishou's Kling 3.0, intensifying competition among Chinese video-model developers; Reuters had reported in early July that MiniMax was also developing a 2.7-trillion-parameter language model.
