Specifically, OpenAI said in an announcement published on its website that its models disproved a central conjecture in an area of discrete geometry tied to Paul Erdős’s planar unit distance problem, a famously stubborn question first posed in 1946. The company said its model found an infinite family of point arrangements that beat the long-favored square-grid intuition. Outside mathematicians checked the results and with one noted researcher calling the result, “a milestone in AI mathematics.”A Novel Approach To Solving A ProblemThe problem begins with a question Erdős posed in 1946: place n points on a plane, then count how many pairs sit exactly one unit apart. For nearly 80 years, mathematicians suspected that the best answers would look roughly like square grids. OpenAI now says one of its internal general-purpose reasoning models has disproved that long-held conjecture by producing an infinite family of examples that have a substantial improvement over the grid-based constructions. After external mathematicians checked the proof, according to OpenAI, they validated the approach. The Guardian reported that mathematicians described t...
