LangChain FAQs
LangChain vs Anthropic Agent SDK vs custom?
LangChain wins for complex multi-agent + RAG. Anthropic Agent SDK wins for simpler agent loops on Claude. Custom code wins for highly specialized requirements.
Does it work with Claude?
Yes. LangChain has first-class Claude support. We commonly build LangChain orchestration on top of Claude's reasoning.
Observability story?
LangSmith is the production observability tool. We set up traces, evals, and monitoring as part of every build.
