Meituan launches LongCat-2.5 with 1M context, multimodal capabilities

Meituan has released LongCat-2.5, a 1.6 trillion parameter Mixture-of-Experts model designed for long-horizon agentic tasks. The model boasts native multimodality, processing both text and visual information through a unified token stream. Key features include OpenAI and Anthropic-compatible API endpoints, a unique 'thinking' object that controls temperature settings, and a 1 million token context window. Meituan claims its benchmarks place LongCat-2.5 between Anthropic's Claude Opus 4.8 and Opus 5, with introductory pricing set at $0.30 per 1 million tokens. AI
