In mid-May, OpenAI announced that an internal AI model had disproved the Erdős unit distance conjecture, a famous problem in discrete geometry that had stumped mathematicians for 80 years. The AI model cleverly applied existing ideas from several subfields of mathematics to create a full proof, though it did not pioneer any genuinely new techniques. The result has since been cleaned up and extended by human mathematicians. OpenAI gave several mathematicians early access to the result and published their reactions. Tim Gowers, a Fields Medal winner, called the solution a milestone in AI mathematics. Daniel Litt, a professor at the University of Toronto, noted that this was the first example of a result produced autonomously by an AI that he found exciting in itself. OpenAI’s new result is the next step in the progression of AI contributing to mathematical research, which has been limited to constrained settings until now. *Source: [arstechnica](https://arstechnica.com/ai/2026/06/openais-math-breakthrough-played-to-ais-strengths/)*
