Meituan releases LongCat-2.0, China's largest AI model trained entirely on domestic chips

Beijing-based food delivery giant Meituan Inc. has open-sourced LongCat-2.0, a massive 1.6 trillion-parameter AI model. The release marks a significant milestone as the model was trained entirely from scratch on a domestic Chinese cluster of 50,000 ASIC chips, bypassing Nvidia hardware. This development comes amid tightening U.S. export controls that have restricted China's access to advanced American processors. Prior to its official launch, Meituan successfully tested the model in stealth as Owl Alpha on OpenRouter, where it reached the global top three by daily volume.

LongCat-2.0 model specifications

• ▪LongCat-2.0 scored 59.5 on SWE-bench Pro and 77.3 on SWE-bench Multilingual, outperforming Gemini 3.1 Pro and GPT-5.5 on those benchmarks
• ▪LongCat-2.0 is a sparse mixture-of-experts model that activates approximately 48 billion parameters per token
• ▪Meituan Inc. released LongCat-2.0, an open-source large language model boasting 1.6 trillion parameters and a 1 million-token context window
• ▪LongCat-2.0 scored 90.0 on IFEval, 81.8 on IMO-AnswerBench, and 88.9 on GPQA-diamond, trailing Gemini and GPT-5.5 on those tests

Domestic Chinese chip training infrastructure

• ▪The full pretraining run and deployment validation of LongCat-2.0 consumed more than 35 trillion tokens on domestic Chinese chips
• ▪Meituan Inc. has not publicly disclosed the specific chip manufacturer or model used to train LongCat-2.0
• ▪Meituan Inc. trained LongCat-2.0 entirely on a domestic Chinese computing cluster consisting of 50,000 application-specific integrated circuit cards

Owl Alpha stealth deployment strategy

• ▪Owl Alpha reached the global top three by daily volume on OpenRouter, ranking first on Hermes Agent and second on Claude Code
• ▪Meituan Inc. deployed LongCat-2.0 anonymously as Owl Alpha on OpenRouter to test the model before its official public announcement

U.S. export control implications

• ▪U.S. export controls since 2022 have restricted Chinese access to advanced Nvidia graphics processing units, prompting China to develop domestic alternatives
• ▪Bernstein estimated that Nvidia's market share for AI chips in China was roughly 40% in 2025, matching Huawei Technologies Co., Ltd.
• ▪The Trump administration's export control directives forced Anthropic to temporarily shut down and limit the release of its Mythos 5 model

Meituan investor reassurance efforts

• ▪Meituan Inc. Chief Executive Officer Wang Xing acknowledged at the annual shareholders' meeting that the company's stock performance was unsatisfactory
• ▪Meituan Inc. Chief Financial Officer Chen Shaohui stated the company is significantly undervalued and plans to resume share buybacks
