OpenAI Reportedly Cracks 80-Year-Old Math Conjecture

OpenAI said the model found an infinite family of point arrangements that beat the classic grid approach, and external mathematicians verified the proof.

  • On Wednesday, OpenAI announced its reasoning model disproved the unit distance problem, solving a famous geometry challenge first posed by Paul Erdős in 1946.
  • For nearly 80 years, mathematicians believed square-grids offered the best solution to the unit distance problem; the model discovered an infinite family of point arrangements performing significantly better.
  • Unlike specialized theorem-proving software, a general-purpose reasoning model generated the proof by connecting the problem to algebraic number theory using Golod-Shafarevich theory, tools rarely applied to geometry.
  • Fields Medal winner Tim Gowers called the achievement a "milestone," while Thomas Bloom suggested the discovery reveals connections between deep number theory and other unsolved geometry problems.
  • Researchers believe systems managing long reasoning chains could assist in biology, physics, and medicine, though the success follows previous inaccurate GPT-5 claims by former VP Kevil Weil.
