arXiv caps submissions at two per person per month as papers surge
What happened
arXiv received 40,363 submissions in September 2026, roughly double the volume of two years earlier, with the cs.AI category up more than sixfold over the same period. To ease the surge, partly driven by AI tools, and the review load, the platform imposed a new limit on all categories starting October 1: each submitter can submit at most two papers per calendar month. The October 11 report says co-authors are unaffected, rejected papers still count against the quota, and deleting a paper before publication restores the slot. The existing cap of three simultaneous submissions under review stays in place. arXiv calls the monthly limit a temporary measure until review tools scale up.

arXiv 自 2026 年 10 月 1 日起，将所有类别的投稿限制为每位提交者每个自然月两篇，以缓解部分由 AI 工具推动的投稿激增和审核压力。2026 年 9 月投稿达 40,363 篇，两年间约翻倍，cs.AI 类别同期增长超过六倍。新限额不影响共同作者，被拒论文仍占额度，发表前删除论文可恢复名额；现有同时最多三篇在审投稿的限制继续保留，平台称新规是审核工具扩容前的临时措施。
