The Shanghai-based company said its H3 model could generate videos of up ​to 15 seconds in 2K resolution with native stereo sound. MiniMax said it planned to release H3's ‌model weights within days, allowing ⁠users to download and customise the underlying system. The move would extend the open-weight approach increasingly adopted by Chinese AI ⁠developers into video generation, where many prominent models remain proprietary. Reuters reported in early July, citing a person with direct knowledge, that MiniMax planned to launch H3 later in the month and that it was developing a 2.7-trillion-parameter language model. Amid ​a growing push in ‌China's AI sector to reduce its dependence on U.S. semiconductors, MiniMax ​said H3 was designed to work with several Chinese-made chips.
