According to CoinMeta, Meituan has officially open-sourced the LongCat-2.5 model, which uses the MIT protocol and supports commercial inference deployment and retraining without the need for additional authorization. The model has a total of 1.6 trillion parameters and can handle up to one million contexts. It has been deeply optimized to work well with domestic computing chips that have limited video memory and bandwidth. LongCat-2.5 is a native multimodal model designed for long-term intelligent agent tasks, and it offers significant improvements in end-to-end delivery capabilities for complex codebase development, complete project construction, visual, coding, and professional office scenarios.
