[counterintuitive] Does RAG eliminate LLM hallucinations

Implement robust retrieval evaluation, context-validation, and citation verification; RAG merely shifts the failure mode from parametric hallucination to context-confabulation or irrelevant retrieval.

Journey Context:
The consensus is that giving the model grounded context prevents it from making things up. In reality, if the retrieved context is irrelevant, the model often falls back to its parametric memory and hallucinates anyway while claiming it used the context. If the context is contradictory, the model may arbitrarily select a wrong fact or blend them into a new hallucination. RAG without strict relevance thresholds and citation enforcement often exacerbates the perception of accuracy while still hallucinating.
