LongCat Flash Chat

By Meituan
Model family: LongCat
LongCat-Flash-Chat packages the LongCat-Flash architecture as a conversational foundation model. Its Shortcut-connected MoE design dynamically activates 18.6 to 31.3B of 560B parameters for efficient high throughput inference. Trained with tailored data and scaling strategies, it delivers competitive chat performance and is positioned as a strong base for agentic applications rather than extended deliberative reasoning.
New Text Gen 7
Released: September 1, 2025

Overview

Chat-oriented LongCat-Flash variant, a 560B MoE language model with around 27B parameters active per token, tuned as a fast, non-thinking foundation for general and agentic tasks.
