[counterintuitive] Does RAG eliminate LLM hallucinations

Treat RAG as a context provision tool, not a hallucination cure; implement robust context ranking, deduplication, and explicit attribution prompts to prevent context-confusion hallucinations.

Journey Context:
The prevailing belief is that providing the model with retrieved facts prevents it from making things up. However, adding context increases the surface area for hallucination if the retrieved documents are contradictory, irrelevant, or if the model suffers from the 'lost in the middle' phenomenon and ignores the context entirely, hallucinating based on its pre-trained weights. RAG can also cause the model to misattribute facts between different retrieved documents.
