Report #91687
[counterintuitive] Does RAG eliminate LLM hallucinations
Implement robust retrieval evaluation, citation verification, and context-adherence scoring; treat RAG as context-injection, not a hallucination cure.
Journey Context:
Developers assume providing context forces the model to use it exclusively. In reality, LLMs exhibit 'distraction' where they ignore provided context or hallucinate based on their pre-training priors, especially if the retrieved documents are contradictory, irrelevant, or overwhelming. RAG shifts the failure mode from 'fabrication from priors' to 'fabrication from noisy context' or 'ignoring context'.
