AI Agents & LLMs 2026: RAG Architectures

This course contains the use of artificial intelligence.

That is not a disclaimer — it is part of the point. The slides and the voice narrating the lectures were produced with AI tools, but every script was written and fact-checked by a human instructor with real hands-on experience. Think of the AI as the production crew; the teaching is human.

Anyone can build a "chat with your documents" demo in an afternoon.

And then you put it in front of real users, on real messy data, and it falls apart. Vague answers. Confident mistakes. "I don't know" when the answer was right there.

Closing that gap is a real engineering discipline. And it has a playbook.

What you will learn:

RAG Architectures is a clear guide to how retrieval systems actually work.

You'll understand the whole pipeline — chunking, embeddings, vector search, hybrid search, reranking, query transformation, and grounding. For each stage: how it works, where it breaks, and the trade-off.

And you'll learn the one thing that matters most: almost every RAG problem is a retrieval problem. Vendor-neutral, no fluff.

What this course covers, module by module:

Why RAG?; The RAG Pipeline; Chunking; Embeddings; Vector Databases; Retrieval; Why Naive RAG Fails; Hybrid Search; Reranking; Query Transformation; Advanced Indexing; Generation & Grounding; Evaluating RAG; Production RAG.

Who this is for:

This is for builders — anyone who has used a language model and now wants retrieval done right, for production.

Let's build retrieval that works.

By the end, you'll understand how a real RAG system is built, debugged, and improved, and know exactly which stage to fix.

Please read — what this course is (and isn't): This is a theoretical, concept-first course. It gives you the mental models and the big picture — the what and the why — in plain language, so that even complete beginners can follow. The lessons are clear slides with narration, not hands-on labs: there are no coding exercises or step-by-step build-alongs, and each topic is a general overview rather than a deep technical dive. If you're looking for hands-on practice or an advanced, in-depth implementation course, this isn't the right fit — and that's by design. Start here to build the understanding; go hands-on elsewhere once the mental model clicks.
