LangChain 完成 3 亿美元 C 轮融资，估值达 30 亿美元
LangChain 拿了 3 亿美元，估值 30 亿，钱主要砸向 LangSmith 这个智能体运维平台。如果你在用 LangGraph 搭智能体，下周的批量发布和周五研讨会值得蹲一下，能看清他们要往平台化走多远。
LangChain 宣布完成 3 亿美元 C 轮融资，估值 30 亿美元。公司判断智能体将改变经济结构，认为掌握自身智能体系的企业才能建立长期竞争壁垒。
这笔资金的核心用途是 LangSmith——一个与框架无关的平台，用于运行、改进和治理智能体，覆盖从开发到生产运维再到合规管控的完整链路。创始人 Harrison Chase 表示还有大量功能待建设。
公司已预告下周将集中发布多款产品，并在周五举办网络研讨会收尾。对开发者而言，LangSmith 与 LangGraph 构成的工具链正从开源框架转向商业化平台，与 Langfuse、Arize 等智能体可观测性产品的竞争会进一步加剧。
we're celebrating this fundraise with a ton of product launches next week, and then a webinar on friday to wrap it all up come join us! events.langchain.com/webinar/future… Harrison Chase @hwchase17 Today we announced that LangChain raised $300M at a $3B valuation. We think agents will transform the economy, and the companies that own their intelligence will build lasting competitive advantages. That's why we're building LangSmith, the framework-agnostic platform to run, improve, and govern agents. Still so much left to build! More on what’s next: langchain.com/blog/series-c
