[counterintuitive] Does RAG eliminate hallucination?

Implement RAG with output validation and source attribution checks; treat RAG as a context grounding mechanism, not a hallucination cure.

Journey Context:
Developers assume providing external documents stops the LLM from fabricating facts. In reality, RAG shifts the failure mode from fabrication to misattribution or context-conflict. The model might still hallucinate by combining two contradictory retrieved documents, or by misinterpreting the retrieved text. RAG reduces ungrounded hallucinations but introduces grounded hallucinations where the model confidently misreads the provided context.
