arXiv caps submissions at two per month as AI paper flood overwhelms moderators
Starting October 1, 2026, arXiv limits submissions to two papers per person per calendar month, keeping the existing cap of three active submissions. The platform says AI tools helped push monthly submissions past 40,000, with the cs.AI category growing more than sixfold in two years and nearly 9,000 support tickets generated. Editorial advisory council chair Thomas G. Dietterich calls the rule a temporary fix until moderation tools scale.
