LangChain moves agent operations into LangSmith: semantic trace search and red teaming before production
LangChain released a set of LangSmith features at Interrupt NYC and London so teams can own their intelligence in production. Previously, finding conversations meant relying on traditional filters; AI Search now retrieves traces by semantic understanding, so a team can ask whether a user got frustrated or whether PII leaked. The same update adds Managed Deep Agents v0.9, Engine v2 with red teaming, Trajectories, Custom Apps, and Fine-Tuning, covering how agents are built, understood, and improved.
