[counterintuitive] Does RAG eliminate LLM hallucinations

Implement explicit verification steps \(e.g., asking the model to cite sources, or using a separate model to verify claims against the retrieved context\) because RAG introduces new failure modes like context ignorance or conflicting context.

Journey Context:
The belief is that giving the model the right facts prevents it from making up facts. In reality, LLMs still hallucinate within the context \(e.g., combining two retrieved chunks incorrectly\) or ignore the context entirely if it conflicts with pre-trained weights. RAG shifts the problem from 'no knowledge' to 'unreliable context adherence'.
