A Harvard mathematician and an AI model may have cracked an 87-year-old math problem

A young mathematician teamed up with a new AI model to tackle one of the hardest open problems in mathematics, and the result is causing a stir among mathematicians and AI researchers on X. Levent Alpöge, a 33-year-old researcher at Harvard University, spent Sunday working with Anthropic’s Fable model to defeat the “Jacobian conjecture,” a notoriously difficult problem proposed by German mathematician Eduard Ott-Heinrich Keller in 1939. The challenge for Alpöge and Fable was to find a counterexample proving the conjecture false (a single verified counterexample would be enough). Alpöge casu...
