Fundamentals of Retrieval Augmented Generation

Learn what RAG is, why it's crucial for grounding LLMs, and its role in enhancing factual accuracy and reducing hallucinations.

What is RAG?

How do chatbots answer accurately about niche or fresh info? Retrieval Augmented Generation (RAG) — it gives the LLM an open-book test by looking up extra context.

LLMs & Their Limits

Plain LLMs have known limits: they hallucinate facts, their knowledge is frozen at training time, and they struggle with niche or private data.
