[counterintuitive] Does RAG eliminate LLM hallucination

Treat RAG as context injection, not a hallucination cure. Implement robust retrieval evaluation, chunking strategies, and citation verification to prevent the model from ignoring context or hallucinating within the provided context.

Journey Context:
Developers assume giving the model the right data means it will use it. In reality, LLMs suffer from 'lost in the middle' \(ignoring middle context\), 'attention distraction' \(over-prioritizing irrelevant retrieved chunks\), and 'sycophancy' \(agreeing with retrieved text even if wrong, or overriding it with parametric memory\). RAG often just changes the source of hallucination from parametric to contextual.
