LangSmith Engine v2 adds agent red teaming and automated fix validation
LangChain · x · 2026-09-24
LangChain announced LangSmith Engine v2 at Interrupt. Engine, an in-platform agent that has analyzed 70M+ traces and diagnosed tens of thousands of issues since May, now red-teams your agent to proactively find bugs and prompt issues before production, detects subtler problems like inefficient paths and trends in error rate, latency, and cost, and automatically tests and validates proposed prompt/code fixes before human review.
