[counterintuitive] Does RAG eliminate LLM hallucinations

Implement robust retrieval evaluation, chunking strategies, and citation verification; RAG grounds the model but does not eliminate its tendency to hallucinate from or ignore the provided context.

Journey Context:
Developers assume providing context forces the model to be truthful. In reality, models can still ignore the context \(context neglect\), hallucinate facts not present in the context, or the retrieval system itself can fetch irrelevant context that the model then confidently uses. Furthermore, the 'lost in the middle' phenomenon means models often ignore context placed in the middle of long prompts, leading to confabulation.
