Signal of the Day#
OpenAI’s general-purpose reasoning model autonomously solved the planar unit distance problem, a famous open mathematical question posed by Paul Erdős in 1946. This marks a historic milestone as the first time an AI system has autonomously solved a prominent open problem central to a field of mathematics, signaling a shift toward AI capable of executing long, difficult chains of reasoning.
