The company claims it is the industry's first trillion-parameter model to complete end-to-end training and inference on Chinese-made processors, though it did not disclose the chip supplier.", "body_md": "Industry context: Demonstrations of end-to-end training on home-grown hardware affect how practitioners assess supply-chain risk, performance trade-offs, and reproducibility. Reuters reports Meituan released and open-sourced a new large language model, LongCat-2.0, which multiple outlets report carries **1.6 trillion parameters** and a **1 million-token** context window. The Next Web quotes Meituan describing LongCat-2.0 as \"the industry's first trillion-parameter model to complete end-to-end training and inference on a 50,000-chip domestic compute cluster.\" Reuters and SCMP report the model was trained from scratch on a **50,000-chip** cluster powered by Chinese-made processors and that Meituan published the weights. CNA and SCMP note Meituan did not disclose which domestic chipmaker supplied the hardware.", "url": "https://wpnews.pro/news/meituan-trains-longcat-2-0-on-domestic-50000-chip-cluster", "canonical_source": "https://letsdatascience.com/news/meituan-trains-longcat-20-on-domestic-50000-chip-cluster-9e94573c", "published_at": "2026-06-30 12:42:44+00:00", "updated_at": "2026-06-30 13:54:21.790435+00:00", "lang": "en", "topics": ["large-language-models", "ai-research", "ai-infrastructure", "ai-chips", "ai-policy"], "entities": ["Meituan", "LongCat-2.0", "Reuters", "The Next Web", "SCMP", "CNA"], "alternates": {"html": "https://wpnews.pro/news/meituan-trains-longcat-2-0-on-domestic-50000-chip-cluster", "markdown": "https://wpnews.pro/news/meituan-trains-longcat-2-0-on-domestic-50000-chip-cluster.md", "text": "https://wpnews.pro/news/meituan-trains-longcat-2-0-on-domestic-50000-chip-cluster.txt", "jsonld": "https://wpnews.pro/news/meituan-trains-longcat-2-0-on-domestic-50000-chip-cluster.jsonld"}}
