Meituan’s LongCat-2.5 API is live, but public weights and independent evaluations remain absent

LongCat-2.5 is presented as a 1.6T-parameter native multimodal model for long-horizon agent tasks. New launch details confirm live API access with OpenAI- and Anthropic-compatible formats and stated context/output limits, but demos are not benchmarks and public weights and independent results remain unavailable.
