Meituan has restricted access to the Doubao large model, requiring all business teams to inspect usage and justify any remaining external model calls. This follows an earlier ban on Alibaba's Qwen model. The company is shifting to its in-house LongCat model, which has been integrated into AI assistants and merchant tools. Meituan recently released LongCat-2.0 with trillion parameters and open-sourced it, supporting ultra-long context and domestic computing clusters, signaling a strategic focus on AI technology sovereignty.
