Meituan Open-Sources 1.6T LongCat-2.0 Trained on Chinese Chips

Meituan has open-sourced LongCat-2.0, a 1.6-trillion-parameter agentic coding model trained end-to-end on a 50,000-chip domestic accelerator cluster, and posted top-tier scores on SWE-bench Pro.

Chinese food-delivery and services giant Meituan has open-sourced LongCat-2.0, a 1.6-trillion-parameter Mixture-of-Experts model built for agentic coding. Released on June 30 and published under an MIT license on Hugging Face, it is the first frontier-scale Chinese model to complete both training and inference end-to-end on a 50,000-chip cluster of domestic accelerators - without Nvidia hardware in the loop.

A trillion-parameter model that fits on domestic silicon

LongCat-2.0 activates only about 48 billion parameters per token on average - dynamically 33B to 56B depending on the input - through Meituan's "Zero-Computation Experts" and ScMoE routing. It supports a native 1 million token context via Long-Cat Sparse Attention (LSA), a linear-complexity sparse attention scheme.

Benchmarks: agentic coding leadership

The team reports 59.5 on SWE-bench Pro and 70.8 on Terminal-Bench, which it says leads Google Gemini 3.1 Pro, OpenAI's GPT-5.5 and Anthropic's Claude Opus 4.6 on deep software-engineering tasks. LongCat-2.0 is available on OpenRouter and has already climbed into the platform's global top three by call volume.

The chip story is the real story

Meituan trained the model on a 50,000-card cluster of domestic ASICs - a milestone in China's push to build frontier AI capacity without US chips. The move follows recent Chinese open-source releases from X Square Robot and comes as Washington tightens export controls on Western frontier models and considers offering a 5% equity stake to the US government.

Positioning against the West

Meituan is also undercutting Western frontier models on pricing, according to reporting from Crypto Briefing, positioning LongCat-2.0 as a cost-competitive agentic-coding alternative to OpenAI, Anthropic and Google offerings.
