Meituan Ships LongCat-2.5-Preview: 1.6T MoE Multimodal Agent Model With 1M Context

Why we picked it

A food-delivery giant shipping a frontier-scale agent model shows how far Chinese consumer tech firms now push into foundation models, though the lack of published benchmarks makes real capability hard to judge. Developers building long-context or agentic workflows should track when independent evals and API access appear, since LongCat competes with open-weight MoE releases from Alibaba's Qwen and DeepSeek. Its 1M-token window targets codebase-scale agent tasks directly.

Meituan released LongCat-2.5-Preview on 25 Sep 2026, a 1.

Body

6T-parameter mixture-of-experts model with roughly 48B active parameters per forward pass.The model offers native 1M-token multimodal context and is aimed at long-horizon software agents.

Meituan did not publish benchmark results in this preview round.
