OpenAI claims three major breakthroughs in physics, mathematics and computer science, including resolving two mathematical conjectures and challenging ETH. OpenAI has claimed a major breakthrough on the Navier-Stokes existence and smoothness problem, a mathematical challenge that has remained unresolved for about 90 years. OpenAI has announced that one of its AI models has solved a long-standing mathematics problem first posed by mathematician Paul Erdős in 1946.
