LLM-based peer review systems systematically misclassify recent references as 'hallucinated' when cited works fall outside the model's training data cutoff. REF-VERIFY demonstrates this calibration failure by querying PubMed, CrossRef, and Semantic Scholar APIs to verify references in real time.

We demonstrate that LLM-based peer review systems (including Gemini) systematically misclassify recent references as hallucinated because they rely on parametric memory rather than live database queries. REF-VERIFY is an executable skill that queries PubMed, CrossRef, and Semantic Scholar APIs to verify references in real time.
