Uptime & Health
No uptime data yet

These providers haven't been health-probed for this model yet. The router still routes around upstreams that fail live requests — uptime fills in once probe history accrues.

About

LongCat-2.5-Preview is Meituan's sparse mixture-of-experts frontier model — ~1.6T total parameters with ~48B active — over a 1M-token context window. It adds native multimodal understanding (image input), stronger coding ability, and a `thinking` toggle, and is built for long-horizon agentic work across terminals, browsers, GUIs, spreadsheets, and design tools. Served over the OpenAI-compatible and Anthropic-compatible APIs.
