OpenAI model disproves ErdΕ‘s unit distance conjecture

+++ OpenAI's general-purpose reasoning model found a counterexample to the ErdΕ‘s unit-distance conjecture, a foundational discrete geometry problem that has stumped mathematicians since 1946, proving once again that brute computational power occasionally accomplishes what decades of human intuition could not. +++

An OpenAI model has disproved a central conjecture in discrete geometry
