[counterintuitive] Does implementing RAG eliminate LLM hallucinations

Treat RAG as a context provision mechanism, not a hallucination cure; implement citation verification and self-correction loops to ensure the model actually uses the retrieved context.

Journey Context:
The belief is that if the model has the right document, it won't hallucinate. In reality, LLMs can still hallucinate with context, either by ignoring the retrieved text \(relying on pre-trained weights\) or by blending the context with parametric knowledge. RAG increases the probability of a grounded answer but does not guarantee it. Models must be explicitly prompted to cite sources, and those citations must be programmatically verified.
