LangChain Courses

LangChain courses help software developers, data scientists, and AI engineers understand how to build context-aware, reasoning-driven applications using Large Language Models (LLMs). These programs teach the principles of prompt engineering, retrieval-augmented generation (RAG), and building complex autonomous agents. They cover everything from basic memory and chains to advanced concepts like LangGraph, MLOps, vector databases, and integrating open-source models like Transformers.
