- Two researchers reviewed 22 submissions across NeurIPS, WACV, and TerraBytes, finding that 68% had fabricated citations or author lists.
- An analysis indicated that tens of thousands of publications in 2025 likely contained invalid AI-generated references.
- An audit of various preprint archives estimated around 146,900 hallucinated citations in 2025, with early-career researchers being the most affected.
- A study found that 85.3% of hallucinated references in bioRxiv preprints remained uncorrected in published versions.
- The share of biomedical papers with at least one fabricated reference increased significantly, from one in 2828 in 2023 to one in 277 in early 2026.
- Some papers were accepted for oral presentations despite containing hallucinated references, with reviewers expressing frustration over the time wasted on such submissions.
- AI-generated reviews are also on the rise, with one analysis showing that 21% of reviews at ICLR 2026 were fully AI-generated.
- The increase in AI involvement in peer reviews raises concerns about the reliability of the review process and the potential for manipulation by authors.
- Reviewers are adapting their workflows to identify AI-generated content, focusing on bibliographies and specific writing patterns indicative of LLM use.
