· 3 pulledMeituan is a household name to me — I use it almost every week for food delivery and local services.
It's honestly a bit surprising, in a good way, to see the same company open-source a 1.6T MoE model under MIT.
The combination of open weights, 1M context, and post-training for coding/agentic workflows really stands out.
LongCat is the AI model series from Meituan, featuring powerful, efficient, and open-source models for complex tasks. Its latest release, LongCat-Flash-Thinking, is a 560B parameter MoE reasoning model that sets a new standard for speed and performance.
