After OpenAI announced its AI disproved an 80-year-old mathematics conjecture, 16 mathematicians published the Leiden Declaration on AI and Mathematics. The statement warns artificial intelligence threatens math as a discipline while acknowledging recent AI breakthroughs in research-level mathematics.

Mathematicians worry about accuracy and reliability, noting editors face a flood of plausible but incorrect AI-generated papers. They question whether AI companies including Google DeepMind and Anthropic prioritize problems amenable to AI methods rather than mathematical significance, potentially distorting research priorities.

The declaration affirms mathematics' values of openness and transparency, contrasting with commercial logic. With the International Mathematical Union's endorsement, mathematicians seek to "recover control of the narrative" about their field's future as AI companies prepare IPOs and shape mathematical research according to business interests.
