A Third of arXiv Papers Read as AI-Written. Research Agents Go Further
A new measurement of 12,750 arXiv papers finds that about a third of recent submissions read as machine-written, up from near zero before ChatGPT, with computer science at 65% and mathematics at 0.7%. The number measures writing style, not who did the research. That gap matters more now that agents like Sakana’s AI Scientist and AutoResearchClaw can go from idea to finished paper on their own.
