[counterintuitive] Does RAG eliminate LLM hallucinations
Implement robust retrieval evaluation, context relevance scoring, and explicit 'insufficient context' fallbacks. Treat RAG as a shift in failure modes—from parametric hallucination to retrieval failure or context-ignoring hallucination—rather than a cure.
Journey Context:
Developers assume giving the model retrieved context means it will use it and stop making things up. In reality, models can still hallucinate by ignoring the retrieved context, or the retrieval system fetches irrelevant or conflicting documents, leading to confused outputs. RAG without retrieval guardrails just gives the model new things to hallucinate about.
