[counterintuitive] Does RAG eliminate LLM hallucinations

Treat RAG as context injection, not a hallucination cure. Implement robust retrieval evaluation, chunking strategies, and citation verification, as irrelevant or conflicting context increases hallucination rates.

Journey Context:
Developers assume providing retrieved context forces the model to base its answer solely on that context. Research shows LLMs suffer from 'distraction'—if retrieved context is irrelevant, contradictory, or too long, the model falls back to its parametric memory or synthesizes a conflicting answer. RAG shifts the failure mode from 'fabricated knowledge' to 'failed retrieval' or 'failed context adherence'.
