LangSmith- AI Observability

Description

LangSmith serves as a specialized management and observability platform designed to refine the development of sophisticated AI applications. Developed by LangChain, the software allows teams to trace execution steps, manage custom datasets, and conduct A/B testing to optimize model performance. It provides a robust framework for evaluating non-deterministic outputs through a variety of metrics, including accuracy-based scoring, LLM-as-a-judge qualitative assessments, and safety checks. The platform is particularly essential for monitoring RAG pipelines and agentic workflows, ensuring that tools are used correctly and responses remain grounded in factual context. Ultimately, it functions as a continuous improvement layer that tracks operational costs, latency, and reliability for production-grade artificial intelligence.
