Share the canonical public link.
LangChain launched LangSmith LLM Gateway in private beta on May 13, 2026. LangSmith LLM Gateway adds runtime governance with spend limits, PII redaction, and policy enforcement directly inside the LangSmith agent lifecycle. It connects blocked requests to traces and Engine fixes without separate infrastructure. LangSmith LLM Gateway integrates with existing tracing, evaluation, and production agents at LangChain customers.
