# Meituan's LongCat-2.0 Becomes First Trillion-Parameter AI Model Trained Entirely on Chinese Chips

> Meituan says its open-sourced LongCat-2.0 is the first trillion-parameter AI model trained and run entirely on Chinese-made chips, without Nvidia hardware.

Beijing-based Meituan, China's food-delivery and services giant, has open-sourced LongCat-2.0, a 1.6-trillion-parameter language model the company says is the first AI system of its scale to complete both pre-training and inference entirely on domestic Chinese hardware. The model ran on a 50,000-chip cluster of homegrown AI processors, coordinated using Huawei's Collective Communication Library in place of Nvidia's NCCL, and was trained on more than 35 trillion tokens.

The distinction matters because pre-training is the most computationally demanding stage of building an AI model. Rival DeepSeek's V4-pro model used domestic chips only for inference, while relying on more capable hardware for training. LongCat-2.0 also ships with a 1 million-token context window and uses a sparse mixture-of-experts architecture, with only 48 billion of its 1.6 trillion parameters active at any time, designed to power AI coding agents and automated workflows.

The release lands as Washington tightens export controls on advanced semiconductors to China, and as Nvidia and Huawei each hold roughly 40% of the Chinese AI chip market. Meituan's claim signals Beijing's push toward chip self-sufficiency is now reaching the most demanding part of AI development, not just running finished models.
