[counterintuitive] Does RAG eliminate LLM hallucinations

Treat RAG as a context-shaping tool, not a hallucination cure. Implement robust retrieval evaluation, chunking strategies, and citation verification, because LLMs will confidently hallucinate within the provided context or ignore it entirely.

Journey Context:
The belief is that if the model has the right document, it will just extract the answer. In reality, models suffer from 'lost in the middle' \(ignoring relevant context placed in the center of the prompt\) and 'attention siphoning' \(over-weighting the prompt format over the retrieved text\). RAG often increases hallucination if the retrieved context is noisy or contradictory, as the model attempts to reconcile the prompt and the conflicting documents.
