What is LangSmith?
LangSmith is an observability and evaluation platform built by the LangChain team, designed specifically for LLM applications. It automatically captures traces of LangChain runs and also works with non-LangChain code. It lets you inspect inputs and outputs at every step of a chain or agent, compare prompt versions, and run evals directly on logged traces.
