[counterintuitive] Does RAG eliminate LLM hallucinations

Implement RAG with robust citation enforcement, retrieval relevance scoring, and explicit 'answer from context or say I don't know' prompting. RAG shifts the problem from parametric hallucination to retrieval failure and context-ignoring hallucination.

Journey Context:
RAG provides external context, but models still hallucinate by contradicting the provided context \(faithfulness hallucination\) or by retrieving irrelevant documents and hallucinating based on them. RAG is a retrieval augmentation, not a truth-enforcement mechanism. If the retriever fails, the generator will confidently hallucinate based on the wrong context, sometimes with higher confidence than a parametric answer.
