[counterintuitive] Does RAG eliminate LLM hallucinations
Implement robust citation verification and retrieval evaluation; RAG merely shifts the failure mode from 'hallucinating facts' to 'hallucinating based on irrelevant or noisy retrieved context'.
Journey Context:
Developers assume giving the model context forces it to use only that context. In reality, LLMs will confidently answer from their parametric memory if the retrieved context is confusing, or they will hallucinate connections between disjointed retrieved chunks. RAG without strict grounding and citation enforcement just creates a more convincing, context-justified hallucination.
