回应撤离中国市场原因,Manus首度披露技术侧经验教训
Di Yi Cai Jing· 2025-07-19 06:17
Manus近期撤出中国市场、清空国内社交账号内容,全力转战海外市场,官方解释原因主要基于经营效率的调整及国际化布局。北京时间7月19日,Manus联 合创始人季逸超发布技术博客,首度从技术角度做出回应,总结创业以来在Agent研发与训练方面的经验教训。 单从技术层面来看,季逸超表示Manus会侧重押注上下文(Context)工程,借助构造"记忆"与流程实现产品快速迭代。主要包括押注上下文、不再训练模 型,强调KV-Cache(Key-Value Cache,一种缓存机制)命中率意义,不动态添加工具,以及用文件系统承载持久上下文等方面。核心即节省底层模型训练 成本,侧重训练效率的提高。 上下文在大模型中通常指模型在处理任务或生成输出内容时所参考的信息集合,能够帮助模型增强理解能力、提高任务性能、增强输出连贯性。此前月之暗 面Kimi创始人杨植麟在采访中强调过上下文的重要性,他称,Ai-native(由AI定义产品形态)产品的终极价值在于提供个性化交互,而无损长上下文 (LosslessLongContext)是达成这一目标的关键。他判断模型的微调长期来看不应存在,用户与模型的交互历史就是最好的个性化过程,而长上 ...
