Hugging Face paper reveals RAG systems misattribute claims to memory

A new paper from Hugging Face investigates the accuracy of citations in retrieval-augmented generation (RAG) systems, finding that a significant percentage of claims are attributed to parametric memory rather than the retrieved context. The study employed a counterfactual value substitution method, replacing facts in retrieved passages with false variants to test model attribution. Results showed that between 1.2% and 15.7% of citable claims were derived from the model's internal memory, with this rate increasing with model size. Standard verification methods like natural language inference proved ineffective, yielding results indistinguishable from chance. AI

IMPACT Highlights a critical flaw in RAG systems that could impact the reliability of AI-generated information and citations.

    Cited but Unused: Parametric Provenance in Retrieval-Augmented Generation

    Retrieval-augmented generation systems attach citations to attribute claims to their sources. These citations frequently misstate provenance, and standard verification cannot detect this. We measure provenance by counterfactual value substitution: a fact in the retrieved passages…
