RAG

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.
