OpenAI makes breakthrough on 80-year-old maths problem

OpenAI's AI model has made progress on the planar unit distance problem, a math question posed 80 years ago asking how many pairs of dots on a sheet can be the same distance apart. The AI disproved the long-standing assumption that square grids provided the best solution by discovering a new family of mathematical arrangements that perform better, though the broader problem remains unsolved. While mathematicians have validated this work, humans were significantly involved in improving and refining the AI's original proof.
