Chinese AI startup MiniMax to open-source 2.7 trillion parameter model

MiniMax's plan to release a 2.7 trillion parameter open-source model reflects a shift in the Chinese AI market toward larger, publicly available models. The company competes directly with DeepSeek, Zhipu, and Moonshot AI, all of which have seen developer interest in their open-source offerings, particularly for organizations seeking economical solutions for high-volume, lower-stakes applications. The model's size—substantially larger than MiniMax's current M3—suggests the company is pursuing performance gains in complex reasoning tasks to match or exceed rival offerings.

However, the release timeline and scope may face headwinds. Recent reports indicate the Chinese government is considering stricter controls on future open-source model releases, which could affect when and how MiniMax distributes the new model. The name M3 Pro remains internal and may change before launch, leaving room for adjustments to the final product. For developers outside China, the release could widen access to large open-source alternatives, though regulatory constraints on the developer side may ultimately shape adoption.
