美团发布开源编码模型LongCat-2.0,采用1.6T参数MoE架构(活跃参数33B-56B),支持1M tokens上下文窗口。该模型在5万块国产芯片上从头训练,使用华为HCCL通信库,验证国内算力集群可胜任大模型预训练。已开源至longcat[.]ai和OpenRouter,调用量全球前三。与DeepSeek-V4-pro仅推理使用国产硬件不同,LongCat-2.0预训练和推理均依赖国产芯片。
🇨🇳China claims a new milestone in locally trained AI, as Meituan rolls out LongCat-2.0.
Meituan, China's food delivery giant, just released LongCat-2.0, an open-source 1.6T-parameter MoE (33B–56B parameters) coding model. 1M tokens context window.
Open-source: Available on longcat[.]ai and OpenRouter, top 3 globally by call volume.
LongCat-2.0 was trained from scratch on 50,000 Chinese domestic chips and Meituan said this proves large-scale model training can now be done on domestic compute clusters.
Shows again the rising push for self-reliance in China’s AI market, as DeepSeek, Alibaba, ByteDance, and others try to depend less on U.S. chips for model training after Washington’s export controls since 2022.
While DeepSeek-V4-pro relied on home-grown chips only for inference, LongCat-2.0 used domestic hardware for both inference and pre-training, according to Meituan.
Meituan did not directly identify its hardware supplier, but said in a WeChat post on Tuesday that it used Huawei Collective Communication Library (HCCL) to make training more stable. HCCL is a chip-to-chip communication system like Nvidia Collective Communication Library (NCCL).
This removed doubts that Atlas-950 SuperPoDs could not train large LLMs for Zhipu AI and DeepSeek.
