What you'll learn

LangChain agents that work perfectly in a notebook routinely fall apart the moment they meet real production traffic — a tool call fails silently, a bad-faith question slips through, or the bill quietly climbs with nobody watching. In this course, Production Deployment and Advanced Topics in LangChain, you'll gain the ability to take a working LangChain agent from notebook to production-grade. First, you'll explore how to deploy it and observe what it's actually doing using LangSmith Deployment and LangSmith's tracing tools. Next, you'll discover how to evaluate it systematically and optimize its latency and cost instead of guessing at both. Finally, you'll learn how to secure it against bad input and design it to fail safely when a dependency goes down. When you're finished with this course, you'll have the skills and knowledge of production LangChain deployment needed to take any LangChain agent live with confidence.
