ArXiv caps submissions at two per month as AI paper flood overwhelms the preprint server
ArXiv is implementing a two-submission-per-month limit to combat a surge in AI-generated papers that has overwhelmed volunteer moderators.
Starting October 1, 2026, ArXiv will restrict users to two submissions per calendar month. The platform has seen monthly submissions exceed 40,000, with the cs.AI category growing sixfold in two years. The policy aims to reduce low-quality volume while maintaining the existing cap of three active submissions at any given time.
