[counterintuitive] Does RAG eliminate LLM hallucinations

Treat RAG as context augmentation, not a hallucination cure. Implement robust retrieval evaluation, chunking strategies, and explicitly instruct the model on how to handle conflicting or insufficient context \(e.g., 'Answer based only on the provided context. If the answer is not contained, say I don't know'\).

Journey Context:
The belief is that giving the model the right facts prevents it from making up facts. In reality, RAG introduces new failure modes: retrieval failures \(wrong chunks\), attention failures \(model ignores the context\), and conflict resolution failures \(model trusts its parametric memory over the retrieved context\). If the retrieved context is irrelevant or contradictory, the model might hallucinate more confidently.
