Learn RAG From Scratch – Python AI Tutorial

freeCodeCamp.org

Lance Martin from LangChain details how to architect advanced Retrieval Augmented Generation (RAG) systems. He demonstrates techniques for query translation, routing, and adaptive flow control using LangGraph, enabling systems to intelligently fetch and verify private data.

Key insight: RAG systems are evolving into 'active' pipelines that use LLMs to grade retrieved documents for relevance and hallucination, automatically triggering reruns or web searches if the quality is insufficient.
