About LangSmith

LangSmith provides observability, evaluation, dataset and prompt workflows for AI applications. Its cloud service requires an account and instrumentation; hybrid and self-hosted options have separate enterprise entitlements. A Developer trace allowance does not make all services free: seats, usage, model calls and additional services can be billed. Traces may include sensitive application content, so review data collection and retention before enabling production instrumentation.
