Meituan Open-Sources LongCat-2.0, a 1.6T Agentic Coding Model Trained Entirely on Chinese Chips
Meituan open-sourced LongCat-2.0, a 1.6-trillion-parameter mixture-of-experts coding model with a one-million-token context window, releasing it under the permissive MIT license on GitHub and Hugging Face. The release unmasked 'Owl Alpha,' the anonymous stealth model that had quietly topped global developer charts on OpenRouter for two months -- and revealed that the entire system was trained and served on a 50,000-card domestic compute cluster with no Nvidia or AMD accelerators. It is the clearest evidence yet that China can build a near-frontier AI stack end to end despite US export controls.
