[counterintuitive] Does Retrieval-Augmented Generation \(RAG\) eliminate LLM hallucinations?

Treat RAG as context augmentation, not a hallucination cure. Implement robust retrieval evaluation, chunking strategies, and prompt grounding techniques \(e.g., asking the model to cite sources\) to mitigate, not eliminate, hallucinations.

Journey Context:
The belief is that providing context forces the model to use only the context. In reality, models can still hallucinate within the context \(e.g., combining disjoint facts incorrectly\) or ignore the context entirely if it conflicts with pre-trained weights \(context dismissal\). RAG often increases user trust without proportionally increasing factual accuracy, a phenomenon known as the illusion of grounding.
