What is RAG?

Retrieve: Understanding RAG fundamentals.

The Problem: LLMs have static knowledge limited to training data, which rapidly becomes outdated.

RAG Solution: Retrieval Augmented Generation tackles two challenges:

1. Keeping knowledge up-to-date: Retrieves current information
2. Providing accurate sources: Supports responses with evidence
