[counterintuitive] Does RAG eliminate LLM hallucinations
Treat RAG as context injection, not a hallucination cure. Implement robust chunking, hybrid search, and an LLM-as-a-judge verification step, because overloaded or conflicting context can actually increase hallucination rates.
Journey Context:
The consensus is that giving the model the right documents forces it to use them, curing hallucinations. In reality, models suffer from 'lost in the middle' attention dilution and can be distracted by irrelevant retrieved chunks. If the retrieved context conflicts with the model's parametric memory, the model often hallucinates a blend of both. RAG shifts the failure mode from 'making things up' to 'misinterpreting provided context'.
