arXiv imposes frequency limits on submissions due to the surge in AI-generated papers

404 Media reports that, starting October 1, arXiv limits each submitter to at most two submissions per calendar month and at most three under review at a time, to ease the burden on volunteer reviewers; co-authors are not counted as submitters. arXiv says submissions have doubled in two years, the cs.AI category has grown more than sixfold, and it has observed an increase in low-value AI-written submissions, but it did not provide an overall share of AI-generated papers. The institution says this is a temporary measure and that the entire growth cannot be attributed to AI, nor should the cs.AI figures be extrapolated to all of computer science.
