LangSmith Engine Automates Failure Detection and Remediation for Agent Workflows
Share the canonical public link.
Ben Tannyhill announced LangSmith Engine on May 13, 2026. LangSmith Engine watches production traces, clusters failures into named issues, and proposes targeted fixes and eval coverage, replacing the prior manual process of reading traces, looking for patterns, writing evals and creating fixes. Users review and merge improvements proposed by the agent. LangSmith Engine is available today in public beta on smith.langchain.com.
