arXiv Restricts Academic Paper Submissions to Combat AI-Generated Content Surge
The scientific preprint repository arXiv has implemented a strict limit of two submissions per researcher per month, effective immediately, in response to a dramatic surge in low-quality submissions generated or assisted by artificial intelligence tools. Submission volume has increased 309 percent over the past decade, with September alone receiving 40,363 submissions compared to 9,869 a decade earlier. The rate limit applies per individual submitter rather than per paper, allowing large collaborative research teams to continue their work with minimal disruption.
arXiv transitioned to independent nonprofit status this summer after operating under Cornell University for 25 years. Previously, the repository relied on moderator judgment to manage submission rates, but the explosion of AI-generated content made manual oversight unsustainable. The organization's editorial leadership noted that a small number of authors account for disproportionate volumes of low-quality submissions, creating bottlenecks that delay review of legitimate research papers by weeks.
The submission cap applies individually rather than per institution, meaning collaborative teams across universities can continue functioning with minimal impact. Notably, rejected papers count toward monthly quotas, and papers must remain under active review status to count against limits.
This restriction could reshape how researchers approach preprint dissemination and may incentivize more careful submission vetting before publication. Legitimate researchers might face temporary delays in sharing work, while institutions coordinating large projects could adapt by staggering individual submissions. The policy may also influence academic hiring and funding decisions that traditionally weight preprint output. However, the measure's temporary nature suggests arXiv is still determining long-term solutions, leaving uncertainty about whether stricter or alternative approaches will eventually emerge.
