Why Naive RAG Fails in Production
Naive RAG (what it usually is)
Index chunks, retrieve top-K, and prompt the LLM. It works in demos — then breaks under real traffic, messy documents, and ambiguous questions.
- Chunking based only on tokens, not meaning.
- No evaluation loop.
- No grounding guarantees.
Production-grade RAG checklist
If you implement only a few things, start here:
- Query understanding and routing (FAQ vs exploratory vs lookup).
- Better segmentation (semantic chunks, headers, tables).
- Retrieval diagnostics (why did we pick these passages?).
- Answer verification (citations, confidence, refusals when needed).
Evaluation loops you actually need
RAG is a retrieval system plus a generation system. Measure both.
- Retrieval: recall@K on a labeled set.
- Generation: faithfulness/grounding + helpfulness.
- End-to-end: task success rate.
Where agents help
Agents are useful when the workflow requires tool use, iterative retrieval, or validation — not just a longer prompt.
- Multi-hop retrieval.
- Structured extraction from documents.
- Compare/contrast across sources with verification.
