Understanding modern RAG
Finally understand how an AI answers from YOUR documents. Chunking, embeddings, vector databases, hybrid search, reranking, hallucinations, GraphRAG, agents, evaluation and production architecture. 26 lessons guided by a concrete end-to-end example, without writing a single line of code.

In short
What you actually get
Everyone talks about RAG, very few people know what actually happens between an uploaded document and a displayed answer. This course opens the black box, step by step, in plain language. You understand why a language model generates instead of searching, how a machine represents meaning, why chunking decides everything, what a vector database is for, and what a similarity score really measures. You then discover the techniques that separate a prototype from a reliable system: hybrid search to also retrieve exact codes and references, query transformation, reranking, context compression, strict prompting, permissions applied before retrieval, hallucination detection. Then the advanced architectures (Corrective, Adaptive and Self-RAG, GraphRAG, Agentic RAG), measurable evaluation, cost and latency control, and the full production architecture. All illustrated by an end-to-end example project: the document assistant of Camille, who runs a forty-person Swiss company. No code to write: technical details live in optional collapsible boxes you open only out of curiosity.

Introduction
An LLM doesn't search, it generatesIf there is one single idea to take away from this whole course, it is this one: a language model does not search for information, it produces text. That sentence sounds harmless. Yet it explains almost every limitation you have observed while using a conversational AI.7 minPreview
How a machine represents meaningWe now know why RAG exists. One unsettling question remains: how can a computer "understand" a sentence? The answer is surprising. It does not understand it. It transforms it.7 minPreview
