Evaluating RAG systems: Key metrics for retrieval and generation quality

This article discusses the critical importance of evaluating retrieval-augmented generation (RAG) systems, focusing on metrics that address both retrieval and generation quality. It highlights that RAG systems often fail silently in the retrieval layer, leading to subtly incorrect answers that can go unnoticed. The piece introduces key metrics such as Precision@K, Recall@K, and Mean Reciprocal Rank (MRR), providing Python code examples and explaining their specific use cases for identifying and preventing regressions before deployment.

    Evaluating RAG — retrieval + generation metrics that matter

    <p>Most RAG systems that silently decay in production decay in the retrieval layer. The LLM output still looks fluent, so the surface tests pass. Users just notice that the answers get subtly wrong — citing the wrong clause, mixing up two customers, giving an outdated version of …
