Fields Medallists’ open letter ‘A Severe Misalignment of AI in Mathematics’ criticises labs’ race for famous problems
Result confirmed
The takeaway
On 11 Sep 2026 about 25 Fields Medallists, including Terence Tao, Peter Scholze, Maryna Viazovska and Pierre Deligne, published an open letter criticising AI labs for treating famous open problems as marketing targets.

- GPT-6 Astra134 days after its cutoff
- Claude Opus 5.573 days after its cutoff
- Gemini 4 Hydrogen164 days after its cutoff
- Grok 4.7103 days after its cutoff
None of these four assistants can know about it. The closest, Claude Opus 5.5, stops 73 days before it.
Key facts
- Signatories: 25 Fields Medallists per Scientific American (Wikipedia lists 26)
- Concerns: announcement by press release or tweet, credit to prior human work, data provenance, and incentives distorting mathematics
- Signatures grew to 7,000+ by 19 Sep 2026 (Po-Shen Loh); the separate Leiden Declaration (June 2026) had 4,000+
- Context: an Aug 2026 arXiv essay ‘The crisis of AI-generated mathematics’ (2608.02859) argued for total opposition; the letter is more moderate
What happened
Three days after OpenAI’s Navier–Stokes announcement, the mathematical establishment’s most decorated members publicly objected to how AI companies pursue and publicise famous problems.
Why it matters
It marked open tension between AI labs and the mathematical community at the moment AI began producing major results, and shaped norms for credit and verification.
