Retrieval-Augmented Generation (RAG) Explained: Architecture, Advanced Types & Comparison

What is Retrieval-Augmented Generation (RAG), and why is it the dominant design pattern in modern AI engineering? In this video, we break down RAG completely: from why standard LLMs fall short to real-world architectures, different RAG variations (Naive vs. Advanced vs. Modular), and how to choose the right strategy for your use case.
