Retrieval-Augmented Generation (RAG) is a framework specifically designed to mitigate hallucinations in large language models by grounding outputs in external, verified data [1], [2], [3]. While it is a primary strategy for reducing these errors [4], [5], [6], it is also noted that RAG systems themselves can still be susceptible to hallucinations due to poor retrieval quality or irrelevant context [7], [8], [9].
