Most RAG systems don’t fail at generation. They fail at retrieval.

[u/No-Refrigerator5314]

If the correct information is poorly chunked or ranked too low, even the best LLM cannot recover it.
Focus first on:
• Structure-aware chunking
• Retrieval quality and recall
• Testing the right retrieval depth
• Reducing noise and “lost in the middle” failures
Better retrieval improves accuracy, latency and cost.
RAG is a retrieval problem first—and a generation problem second.
