MiniMax, which was founded in 2022, is one of China's "AI tigers," a group of well-funded start-ups competing with domestic tech giants and US leaders in the foundation models market.

The company went public in Hong Kong earlier this year.

The H3 model is targeted at commercial applications such as advertising, e-commerce, product design, and gaming.

MiniMax claims that generating 2K video with its new model would cost less than a third of mainstream rival products.
