美团否认LongCat基础模型负责人裴鹏离职的传言。裴鹏2023年加入美团，主导研发了业界首个全流程国产算力的万亿参数大模型LongCat-2.0，该模型发布尚不足一月。消息传出不到一天即被官方辟谣。
7月27日，美团上线全场景AI Agent平台CatPaw，搭载刚开源的万亿参数大模型LongCat2.0。该模型总参数1.6T，原生支持1M超长上下文，首次在五万张国产算力卡上完成全流程训练与推理。CatPaw将这一底层能力转化为开箱即用的企业级智能工作台与Agent开发托管平台，标志着美团大模型从技术开源全面迈向产业落地。
美团7月27日否认LongCat团队基础模型负责人裴鹏离职传闻，称消息不实。裴鹏毕业于北大，2023年加入美团，先后任基座模型预训练负责人及LongCat基础模型负责人，全面主导大语言模型、多模态模型与Agent智能体的研发，并牵头万亿参数大模型LongCat-2.0的研发与落地。
搜索智能体评测基准BrowseComp短期被“刷爆”，成绩从30%飙到90%而逐渐失效。7月17日，美团LongCat发布新基准LoHoSearch，基于含762万实体的维基百科知识图谱自动生成难题，意图将评测重新推入高难度区，重设搜索智能体能力标尺。
