MiniMax plans its biggest model yet, a 2.7-trillion-parameter system it intends to open-source, The Information reports. It would be the largest Chinese model on the market, and another squeeze on US labs’ margins.

China’s open-model push has a new heavyweight on the way. MiniMax plans a large language model with 2.7 trillion parameters, The Information reports, citing two people familiar with the effort. It would dwarf the firm’s current flagship and rank as China’s largest model yet.

Inside MiniMax, the model goes by M3 Pro. The final name may change. The company aims to open-source it, and a release could land as early as the third quarter.

The scale of the jump is the headline. MiniMax’s current flagship, M3, holds 428 billion parameters. The new model runs roughly six times bigger. Bigger models tend to handle complex reasoning and multi-step tasks better, which is exactly where the frontier race now sits.
