Testing & Evaluating Your RAG App
Build confidence in your first RAG application by creating a test set and measuring retrieval and answer quality with practical metrics before you ship.
Why Evaluate RAG
A RAG app can look fine on a few queries and fail badly on others. Without measurement you cannot tell if a change helped or hurt.
Evaluation gives you a repeatable score to guide improvements.
Two Things to Measure
RAG quality has two parts:
- Retrieval: did we fetch the right documents?
- Generation: did the answer use them correctly?
A bad answer can come from either, so measure both.
