Briefings

arXiv implemented a rate limit to combat AI-generated spam submissions, restricting new authors to two papers per month and allowing only three active submissions simultaneously. This policy follows a long-term effort to reduce low-effort content, including bans on AI slop and removal of review articles. The archive cites a surge in narrow-scope and salami papers driven by AI tools, noting that while AI is permitted as a research tool, many submissions now fail to meet scholarly standards. Key statistics show submission volume grew from 9,869 in September 2016 to 40,363 in September 2026, with submissions doubling in the last two years. The specific number of active submissions allowed per author remains a fixed policy limit rather than a dynamic threshold.

Key points

• arXiv restricts new authors to a maximum of two papers per calendar month and allows only three active submissions simultaneously to manage AI-generated spam.
• The policy update was implemented after a year-long effort to ban AI slop and remove review articles, citing the inability to keep up with submissions.

Context and limitations

Data reflects September 2016, September 2024, and September 2026 submissions; specific submission counts for other months are unavailable. The exact number of active submissions allowed per author is a fixed policy limit rather than a dynamic threshold. Some submissions may have been rejected before reaching the rate limit threshold.
