How to test RAG

RAG systems answer queries by retrieving relevant information and then feeding it in a prompt to an LLM.

AI developers constantly ask how to test their RAG system to systematically make it better.

So, I wrote a post to share best practices we see from research and customers.

Key takeaways: • Get a test query set with "good" answers, automate running queries through the system, and then grade with an LLM on factualness • Enhance by grading on more dimensions / individual steps from there
