RAG Explained in 12 Minutes

If you've been wondering what RAG (Retrieval-Augmented Generation) is and why everyone in AI is talking about it, this video is for you! In this video, I'm going to be doing a complete, no-fluff deep dive into the world of RAG.

We break down the foundational concepts using simple analogies, debunk the biggest myths (no, RAG is not dead, and massive context windows won't replace it!), and explore the actual architecture behind successful enterprise AI systems. Finally, I'll walk you through the 10 essential RAG patterns you need to master in 2026 to build smarter, faster, and more accurate AI applications.

I am launching Mastering Agentic AI, a 6-week intensive, technical, and project-based bootcamp starting May 30th. And for my YouTube family, I am giving an exclusive 10% discount. Link is in the description.

This is not just for software engineers and AI engineers. If you are an AI PM, a PMM, a go-to-market expert, or in any adjacent role building AI products, this is for you too. Being technical is no longer only an engineer's thing. Every week you will be working on real projects in two flavors: coding and SDK-based for engineers, and no-code or low-code for tech leads, PMs, and everyone else.
