[counterintuitive] Does RAG eliminate LLM hallucination

Treat RAG as context augmentation, not a hallucination cure. Implement robust retrieval evaluation, chunking strategies, and citation verification, as LLMs can still hallucinate from retrieved context or ignore it.

Journey Context:
The belief is that giving the model the 'right answer' in the prompt stops it from making things up. In reality, models suffer from 'attention dilution' or 'lost in the middle' phenomena, ignoring retrieved context and hallucinating anyway, or hallucinating based on the retrieved text. RAG shifts the failure mode from fabrication from pretraining to fabrication from context or context ignorance.
