[counterintuitive] Does RAG eliminate LLM hallucinations

Treat RAG as a context expansion tool, not a hallucination cure. Implement strict relevance scoring, contradiction detection, and force the model to cite sources. If retrieved documents conflict or are irrelevant, instruct the model to explicitly state it lacks sufficient information rather than synthesizing an answer.

Journey Context:
Developers assume giving the model the 'right answer' in context stops it from making things up. In reality, irrelevant context distracts the model, and conflicting contexts cause it to blend facts. The model can also hallucinate that a retrieved document supports a claim when it does not \(sycophancy\), or confidently rely on a retrieved document that is itself factually incorrect.
