CHICAGO: Detecting Errors Early with LangSmith
Join us in Chicago on March 3rd for an evening of LangChain insights, AI talks, and community connections!
What to expect:
A practical, real-world discussion on building and operating production-ready AI applications with LangChain. We’ll walk through a real production incident, what went wrong, and how better evaluation and observability with LangSmith would have surfaced issues earlier.
Whether you’re building RAG pipelines, experimenting with agents, or scaling LLM-powered applications, this session focuses on the lessons that only emerge once systems hit production.
