AsianFin -- Meituan on Monday launched LongCat-Flash-Thinking, a high-efficiency reasoning large language model that integrates both “deep thinking + tool use” and “informal + formal” reasoning capabilities.
According to the company, it is the first of its kind in China and has achieved state-of-the-art performance among open-source models worldwide in logic, mathematics, coding, and agent-based reasoning tasks. In some benchmarks, its performance approaches that of the closed-source GPT-5-Thinking. The model is now available for trial on Meituan’s official website.
