Retrieval-augmented generation (RAG) systems often fail in production not due to the language model itself, but due to issues in the underlying infrastructure, data quality, or retrieval logic. Problems with documents, metadata, permissions, and outdated policies can lead to incorrect responses even when the language model performs well. Teams may mistakenly focus on optimizing the model or prompts, wasting time when the root cause lies in pre-model components of the system. AI
