LangChain announced that LangSmith can now track cache hit rates for agents: view an overall hit-rate stat, break it down thread by thread, and chart it over time with dashboard templates. Engineer Sydney Runkle, sharing from experience, notes it helps catch gnarly — and costly — bugs, since cached LLM calls are cheaper and faster.
