• AI detection company GPTZero found at least 100 hallucinated citations in 51 of 4,841 papers analyzed from the NeurIPS 2025 AI conference – despite the papers passing through peer review.
• Submissions to NeurIPS increased by more than 220 percent between 2020 and 2025, from 9,467 to 21,575, overwhelming the system. Distrust of reviewers is also growing, with some reportedly using AI tools instead of reading papers.
• The findings include papers from top American universities and providers like Google.”
