Foreign Media: On September 2, 2025, Meituan announced the launch and open-sourcing of its self-developed large language model LongCat-Flash-Chat, with release channels including Hugging Face, GitHub, and its official website. This is an important achievement in the field of artificial intelligence for Meituan since its acquisition of AI startup Light Year for $281 million in 2023.
The model has 560 billion parameters and uses a Mixture-of-Experts (MoE) architecture, which collaborates through multiple "expert sub-networks" to handle tasks. In technical evaluations, its performance is comparable to DeepSeek V3.1, Alibaba Cloud Qwen3 series, Moonshot AI's Kimi K2, as well as American models such as Anthropic Claude Sonnet and Google Gemini 2.5 Flash.
As the long-term leader in China's food delivery market, Meituan is entering the AI arena through an open-source model, narrowing the gap with international giants, and promoting the development of the third-party developer ecosystem.
