Meituan said it expanded training on long task sequences and used large-scale reinforcement learning to improve work on complex codebases and complete software projects, and it converts failures encountered by real agents into reproducible training tasks. LongCat-2.5 processes visual and text inputs in a unified token framework for visual coding, creative design and 3D tasks, and is available through Meituan's online chat service and API platform, with GitHub and Hugging Face releases planned to follow.", "body_md": "Meituan released LongCat-2.5 on November 2, adding stronger visual understanding and coding capabilities to its AI model lineup.
