OpenAI's internal reasoning model has disproved the 80-year-old planar unit distance conjecture, originally proposed by mathematician Paul Erdős in 1946. The conjecture questioned the maximum number of pairs of points exactly one unit apart in a plane, with Erdős suggesting a growth rate of n raised to the power of 1 plus a constant divided by log log n. OpenAI's model discovered configurations achieving approximately n^(1+0.014) unit distances, surpassing previous constructions based on square grids. The AI's breakthrough was validated by Fields Medalist Tim Gowers and formalized by Princeton mathematician Will Sawin, confirming its academic rigor. This development not only challenges a longstanding mathematical assumption but also highlights the AI's ability to connect geometry with algebraic number theory, potentially impacting fields like computational geometry and network design.
