| description.long | A managed platform for building and deploying AI agents that break down multi-step requests, retrieve information from knowledge bases and data sources, and execute tasks autonomously. Agents use foundation model reasoning to understand intent, gather relevant context, and coordinate actions across company systems. | LangSmith provides observability through tracing to debug agent behavior, evaluation capabilities to test and score agents with human review and automated assessments, and deployment services to run agents at scale. |
