arXiv, the world's largest preprint server, announced a new submission limit of two papers per author per month, effective October 2026. The decision comes after monthly submissions across the platform doubled in just two years, with the cs.AI category experiencing growth of more than sixfold.
According to arXiv, a small fraction of authors are responsible for flooding the platform with low-quality or repetitive submissions, straining moderation resources and degrading the signal-to-noise ratio for researchers trying to stay current.
The cap is likely to be welcomed by many researchers who have struggled to keep up with the sheer volume of AI preprints. It may also discourage mass submission strategies where authors upload numerous minor variations of the same work to game visibility.
However, the policy could also raise concerns about fairness, particularly for prolific researchers or teams working across multiple subfields. Critics may argue that a blanket cap does not distinguish between legitimate high-output groups and spam generators, and that moderation improvements might be a more targeted solution.
The move underscores a broader challenge facing AI research infrastructure: the pace of output has outstripped the capacity of traditional curation and review systems, forcing institutions to adopt new guardrails.
