OpenAI Pulls Caltech Mathathon Sponsorship After Mathematicians' Open Letter
On September 11, OpenAI officially announced it would withdraw its sponsorship of Caltech's Mathathon competition after considering concerns raised by members of the mathematics community, and notified the organizers. The decision followed an open letter by mathematicians criticizing AI-generated math content as "slop," signed by several prominent scholars including Fields Medalists.
Confirmed
- Per Business Insider (relayed by @exophades), mathematicians published an open letter criticizing AI-generated mathematical content as slop, citing concerns about AI eroding the mathematical research ecosystem.
- Per a Reddit post (@YakFull8300), the letter was signed by leading figures including 2018 Fields Medalists Peter Scholze and Alessio Figalli, and 2022 winner Hugo (post truncated; see original letter for the full list).
- Per @ns123abc, the Mathathon had participants use large models on research-level math problems and was sponsored by multiple AI companies; the letter was signed by current and former Caltech mathematicians.
- OpenAI (via @danintheory) confirmed the withdrawal, acknowledging that rapid AI progress in math is disruptive and expressing a desire for further dialogue with the community.
- Background: per @soumitrashukla9, Caltech undergraduates had planned to use OpenAI-provided AI credits to attack open math problems — a generational clash that sparked the protest.
- Comments under @TinfoilTricorn noted the event lacked remote participation options, excluding those unable to attend in person.
Why it matters
- This is a landmark case of an AI company withdrawing sponsorship after collective community pushback, with Fields Medalists among the protesters — revealing a generational split in mathematics over AI's role: younger researchers want AI-assisted breakthroughs while senior mathematicians fear low-quality AI content polluting the field.
- OpenAI's choice to withdraw and engage in dialogue offers a template for how AI companies and academia may interact going forward.
