[counterintuitive] Does RAG eliminate LLM hallucinations

Implement retrieval validation \(e.g., citation verification, self-RAG\) and acknowledge that RAG merely shifts the failure mode from 'fabricating facts' to 'misinterpreting retrieved context' or 'retrieving irrelevant documents'.

Journey Context:
Developers assume providing the model with retrieved documents stops it from making things up. However, LLMs still hallucinate within the context window, often contradicting the provided text or incorrectly combining retrieved chunks. RAG can even increase hallucination if the retrieved context is noisy, conflicting, or irrelevant, as the model feels compelled to use the provided context even if it doesn't contain the answer.
