Chinese AI firm MiniMax launched its H3 multimodal video-generation model on July 31, 2026. The model produces 15-second 2K videos with stereo sound at less than one-third the cost of mainstream rivals. To challenge competitors like ByteDance and Kuaishou, MiniMax plans to release H3's model weights. Additionally, the model is designed to run on Chinese-made chips, supporting domestic efforts to reduce reliance on U.S. semiconductors.
MiniMax H3 model launch
- ▪The MiniMax H3 model can generate videos of up to 15 seconds in 2K resolution with native stereo sound
- ▪Chinese AI firm MiniMax released a new multimodal video-generation model named H3 on July 31, 2026
- ▪MiniMax, founded in 2022, listed publicly in Hong Kong in January 2026, becoming the second of China's "AI tigers" to list
- ▪The MiniMax H3 model can process text, images, video, and audio, as well as edit existing content and transfer movements between videos
Chinese AI video competition
- ▪Competition among Chinese video-model developers intensified following ByteDance's release of Seedance 2.0 and Kuaishou's release of Kling 3.0
- ▪MiniMax's H3 model launch steps up competition in China's fast-growing video-generation market led by rivals ByteDance and Kuaishou
Open-weight model release strategy
- ▪MiniMax plans to release the model weights for H3 within days of its July 31, 2026 launch, allowing users to download and customize the underlying system
- ▪The open-weight release of H3 extends an approach increasingly adopted by Chinese AI developers into video generation, where many prominent models remain proprietary
Commercial applications pricing
- ▪MiniMax stated that generating 2K video using the H3 model would cost less than one-third of mainstream rival products
- ▪MiniMax designed the H3 model for commercial applications including advertising, e-commerce, product design, and games
Chinese semiconductor independence push
- ▪MiniMax designed its H3 video-generation model to work with several Chinese-made chips
- ▪The integration of Chinese-made chips in MiniMax's H3 model comes amid a growing push in China's AI sector to reduce dependence on U.S. semiconductors
