Why production RAG fails — and the boring metrics that fix it
The article discusses the common failures in production RAG (Retrieval-Augmented Generation) systems and how to address them. It emphasizes the importance of measuring specific metrics to identify whether issues arise from the retriever or the generator. By implementing a structured approach to evaluation, teams can improve their RAG pipelines effectively.
- ▪Most production RAG pipelines underperform because teams treat retrieval as a solved problem and blame the generator for incorrect answers.
- ▪To diagnose issues, teams should measure retrieval recall, faithfulness, and answer relevance separately.
- ▪The article outlines four main failure modes in RAG systems and provides strategies for fixing them.

The "RAG is dead, long context replaces it" framing is the wrong fight.
