LongCat-2.5 is Meituan's natively multimodal agentic model: a sparse mixture-of-experts with 1.6T total parameters and about 48B active, over a 1M-token context window. It takes text and image input and returns text. It is built for long-horizon agentic work, agentic coding, and visual coding such as creative design and 3D tasks, and has a `thinking` toggle. Served over the OpenAI-compatible and Anthropic-compatible APIs.
