Large language models do not know your private company data. They are trained on public information, not your internal documents. That is where RAG (Retrieval Augmented Generation) comes in. In this video, I break down how production-ready RAG systems are actually built, beyond simple demos and tutorials. You will learn how real companies design RAG systems that scale, stay accurate, and work reliably in production. We also look at how serverless Postgres with vector support (like Neon) fits into modern AI architectures.
