Meituan’s LongCat API platform launches LongCat-2.5-Preview with 1.6T parameters
Meituan listed LongCat-2.5-Preview with 1.6 trillion parameters on its LongCat API platform on September 25, targeting long-horizon tasks and multimodality.
On September 25, Meituan listed LongCat-2.5-Preview — a 1.6-trillion-parameter model targeting long-horizon tasks and multimodality — on its LongCat API open platform, opening both API and web experience endpoints simultaneously. The model is being released in Preview form pending validation.
For Meituan, model capability maps directly onto complex scheduling, multi-turn interaction, and content understanding in local-life services. Long-horizon tasks in particular fit the multi-step decision chains of food delivery and in-store merchant workflows. Whether LongCat-2.5-Preview can translate into measurable business outcomes — beyond leaderboard and parameter headlines — will be the key indicator going forward.
