Question 1

How do you evaluate RAG quality?

Accepted Answer

By measuring Retrieval Recall (did you get the right context?) and Generation Faithfulness (did the LLM answer match the context?).

Question 2

Why use RAG instead of fine-tuning?

Accepted Answer

RAG is cheaper, faster, allows real-time data updates, and provides clear citations for answers without risk of hallucination.

Question 3

What is the role of the LLM in RAG?

Accepted Answer

The LLM does not search for information; it only reads the retrieved paragraphs and summarizes them into a clean answer.

Question 4

Does RAG work for private internal datasets?

Accepted Answer
