The Complete LangChain & RAG Developer Course 2026

About this course

Build Production-Ready AI Applications with LangChain, OpenAI, FAISS & ChromaDBMaster Retrieval-Augmented Generation (RAG) and Build Real AI Systems from ScratchAre you ready to master one of the most in-demand skills in Generative AI engineering?

Welcome to The Complete LangChain & RAG Developer Course 2026 — a hands-on, beginner-friendly course designed to help you build powerful AI applications using LangChain, OpenAI, FAISS, ChromaDB, and Retrieval-Augmented Generation (RAG).

In this course, you’ll learn how modern AI systems like ChatGPT-style assistants retrieve real-time knowledge from PDFs, documents, databases, and custom data sources to generate accurate, context-aware responses.

This is not just theory.

You will build a complete end-to-end RAG application using real-world workflows and industry-standard tools used by modern AI engineers.
