Naive RAG: Basic Retrieve-Then-Generate

~10 min read

The baseline RAG architecture: embed the query, retrieve by vector similarity, stuff the results into the prompt, generate once. Simple, fast, and the right starting point before reaching for anything fancier.

Key points

  • Naive RAG: embed the query, retrieve by vector similarity, generate once — no validation, no iteration, no adaptability
  • Works best for simple, fact-based queries where the question and answer are semantically close
  • Weaknesses: retrieve-once/generate-once means no recovery if context is insufficient, and irrelevant chunks get used without checking
  • Every other RAG architecture in this taxonomy is a targeted fix for one of Naive RAG's specific weaknesses
  • The right default: start with Naive RAG, and move to something fancier only once you hit a specific, documented failure it can't handle
