Retrieval-Augmented Generation Failures

Researchers identified a critical flaw in large-scale RAG architectures where system confidence inversely correlates with accuracy as memory context expands, a failure often missed by standard monitoring tools 1. This effect manifests as the system providing increasingly incorrect answers while reporting higher certainty scores, necessitating the development of novel internal memory layers to mitigate these hidden degradations 1.
