Chinese AI startup MiniMax is developing a 2.7 trillion parameter language model planned for open-source release as early as Q3. The model would surpass any existing Chinese AI model in size and compete directly with other open-source offerings, though emerging government controls on such releases may affect the timeline.

MiniMax, a Chinese AI developer, is working on a new large language model called M3 Pro with 2.7 trillion parameters and plans to release it as open source, potentially as early as Q3. The model would be larger than any other Chinese AI model currently on the market.
Why it matters
Open-source models from Chinese developers have gained traction with engineers seeking cost-effective options for high-volume, less critical tasks. MiniMax's release would expand competition in this space alongside rivals like Zhipu, DeepSeek, and Moonshot AI, though the Chinese government appears to be considering tighter controls on future open-source model releases.
What to watch
The release could come as early as Q3, though the internal name M3 Pro may change before launch. MiniMax's current top model, M3, has 428 billion parameters, making the new model substantially larger.
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.
