LangSmith Engine v2 adds red teaming and automated fix validation for agents

LangChain · x · 2026-10-01

LangChain launched LangSmith Engine v2 with three key upgrades: proactive red teaming that surfaces verified issues like hallucinations and system-prompt violations before production; detection of subtler problems such as inefficient agent paths and trends in error rate, latency and cost; and automated validation of proposed prompt/code fixes before human review. Since its May launch, Engine has analyzed 70M+ traces and diagnosed tens of thousands of issues, grouping related traces with root cause, proposed fix, and eval dataset ground truth.
