GPTZero finds 100 new hallucinations in NeurIPS 2025 accepted papers (gptzero.me)

GPTZero has identified over 100 hallucinated citations in 53 papers accepted at NeurIPS 2025 using its Hallucination Check tool, which scrutinizes citations for accuracy. This finding follows a similar investigation into ICLR 2026 submissions, reflecting a broader concern in the AI/ML academic community about the increasing prevalence of citation inaccuracies fueled by generative AI. As the volume of submissions to major conferences like NeurIPS has surged—growing by over 220% from 2020 to 2025—peer review processes are becoming overwhelmed, leading to oversight issues even among multiple reviewers. The significance of these findings is substantial, highlighting vulnerabilities in the peer review system that are exacerbated by the pressures of publication. Papers with hallucinated citations, which could be grounds for rejection under the NeurIPS LLM policy, raise questions about the rigor and reliability of accepted research. GPTZero's Hallucination Check not only flags potential citation inaccuracies but also aids authors and reviewers alike, promoting transparency and efficiency in the evaluation process. By bringing these issues to light, GPTZero aims to improve the integrity of academic publishing amidst the challenges posed by AI technologies.
