LongCat 2.5 now available on AI Gateway

Meituan's LongCat 2.5 model is now available on Vercel's AI Gateway under the model name `meituan/longcat-2.5`, adding native visual understanding, coding and multi-step tool use for agents working across complex codebases and full-project builds. The model accepts text and image inputs with a 1M-token context window covering code, documents and extended task histories, and Meituan highlights improvements in visual programming, creative design and 3D tasks alongside longer agent workflows that carry engineering work from planning through execution. Vercel said AI Gateway reflects provider pricing with no markup and charges no platform fee on inference, including on Bring Your Own Key requests.
