38%
of 7,899 new arXiv maths papers acknowledged using AI, September 2026 (1.7% a year earlier)
What the chart shows
Epoch AI reads the full text of every new arXiv mathematics paper and records whether the authors acknowledge using AI, and for what. In September 2026, 38% of 7,899 papers did, against 1.7% a year earlier.
Most credit AI with writing and editing (26% of all papers) or research help (19%). 9.0% credit it with a substantial contribution to the research itself, and 1.7% with formal, machine-checked proofs.

How to read it
- A paper can acknowledge several uses, so the categories add up to more than the share using AI at all.
- Acknowledgements are what authors choose to declare; papers that used AI without saying so are not counted.
- For AI use across other fields, see the panel on the AI in Science topic.
