Retrieval-augmented generation (RAG) systems often fail due to poor retrieval rather than generation issues. To improve RAG performance, developers should focus on chunking documents at semantic boundaries, using hybrid search (combining keyword and vector search), and reranking retrieved documents for precision. Implementing metadata filters and ensuring the system can refuse to answer when context is insufficient are also critical for reliable RAG. AI
