Report #70781
[counterintuitive] Does RAG eliminate LLM hallucination
Implement retrieval validation \(e.g., asking the model to cite sources from the retrieved context\) and position critical information at the beginning or end of the context window.
Journey Context:
The belief is that providing external documents anchors the model to facts. In reality, models suffer from the 'lost in the middle' phenomenon where they ignore context placed in the middle of long prompts. Furthermore, models often hallucinate that the provided context supports a claim when it doesn't, or they rely on their parametric memory over the provided context if the context is weak.
