Udemy – The Complete LangChain, LangGraph, & LangSmith Course (2026)

Welcome to the most complete, up-to-date guide on the modern AI stack: LangChain, LangGraph, and LangSmith. In 2026, building a simple wrapper around an LLM is no longer enough. To create applications that are truly useful, they must be reliable, stateful, and observable. This course is designed to take you from a beginner to a professional AI Engineer by mastering the three pillars of the LangChain ecosystem.

We begin with LangChain, where you will learn to move beyond basic API calls using the LangChain Expression Language (LCEL). You’ll master the art of orchestration, building “Runnable Chains” that are efficient, asynchronous, and production-ready. From there, we transition into LangGraph, the industry standard for building agentic workflows. You will learn to move away from linear chains and into cyclic state machines, implementing persistence with Checkpointers so your agents never “forget” a conversation or lose their place during a crash.

Finally, we bridge the gap between development and production with LangSmith. You will learn how to monitor your applications in real-time, debug complex reasoning paths with detailed traces, and use evaluation suites to ensure your AI behaves exactly as intended. This isn’t just a coding course; it’s a blueprint for building enterprise-grade AI systems that are as robust as they are intelligent.
