LangSmith now supports OpenTelemetry, bringing distributed tracing and end-to-end visibility to your LLM observability workflow.

Ingest traces in OpenLLMetry format to unify LLM monitoring and system telemetry data. You can identify errors and bottlenecks, track key metrics, and gain deeper insights across your stack of programming languages, frameworks, and monitoring tools.

There's multiple ways to get started, including with an OpenTelemetry based client, with Traceloop SDK, or with the Vercel AI SDK.
