Meituan open sources LongCat-2.0, the 1.6T, near-frontier agentic coding model trained entirely on Chinese chips

Meituan open-sourced LongCat-2.0, a 1.6-trillion-parameter Mixture-of-Experts coding model trained entirely on a cluster of more than 50,000 Chinese-made ASIC chips, with no Nvidia hardware involved. Released under the MIT license with a 1-million-token context window, the model scored 59.5 on SWE-bench Pro, edging out GPT-5.5's 58.6, and had already topped OpenRouter's rankings under the codename Owl Alpha before its identity was disclosed.
