For decades, solving the world’s hardest mathematical problems has been considered a uniquely human pursuit, requiring imagination, persistence and the ability to explore ideas beyond established methods. Artificial intelligence, meanwhile, has largely been viewed as a tool for computation and analysis.

Mathematicians have been trying to prove the Jacobian conjecture for nearly a century, but now the Claude Fable 5 AI has apparently found a counterexample that disproves it

An 87-year-old mathematical puzzle was solved using AI, surprising experts and marking the most complex problem yet tackled by artificial intelligence.
