Chinese AI developer MiniMax is building a language model with 2.7 trillion parameters, dubbed M3 Pro, with an open source release targeted for the third quarter, according to sources familiar with the project.

The system is the largest open weight model currently available from China, exceeding the parameter size of MiniMax’s existing M3 version by more than six times. Competitors including Kimi and Zhipu have recently expanded their open source capabilities, underscoring a sustained push by Chinese developers to benchmark large foundation models.

Huge: China’s MiniMax Plans to Launch 2.7-Trillion Parameter Model (MiniMax Pro) tl;dr MiniMax is preparing a 2.7T parameter open-source model, potentially launching as early as Q3. That would make it far larger than any Chinese model cur

@teortaxestex

Minimax needs to flip the narrative. With 2.7T it should be possible. Go on, surprise me. Kimi did it, Zhipu did it. Can you?

Why it matters: An open-weight 2.7T-parameter frontier model from a capable Chinese lab (MiniMax) is a DeepSeek-style threat to closed-lab margins and the AI-capex return thesis, pressuring NVDA/closed-lab proxies while lifting China AI names.

At publish time: Headline states a 2.7T-parameter open-source model, 6x larger than MiniMax's prior open weight and the largest from China, targeted for Q3 release — an open-weight frontier competitive threat is flaggable from the facts alone.

Open-weight frontier wave intensified (Soofi, Inkling, Moonshot Kimi K3 2.8T) plus China/US model curbs, confirming DeepSeek-style threat thesis; no clear NVDA/closed-lab price hit.
