[counterintuitive] Does RAG eliminate LLM hallucination

Treat RAG as a context-awareness tool, not a hallucination cure. Deduplicate, rank, and strictly limit retrieved chunks to only highly relevant information to prevent context confusion.

Journey Context:
The belief is that giving the model the 'right answer' in context stops it from making things up. In reality, noisy or conflicting retrieved documents cause the model to hallucinate by blending unrelated facts \(context confusion\) or ignoring context entirely. Less is often more in RAG; irrelevant context degrades the model's ability to ground its response.
