AI tool Fable 5 allegedly disproves the Jacobian conjecture
A mathematician, Levent Alpöge, used Anthropic’s Fable 5 to claim a counterexample to the Jacobian conjecture, a nearly 90-year open problem in algebraic geometry. Experts warn that a single counterexample, while notable, is not equivalent to a full proof and may offer limited insight, though the episode underscores AI’s potential in assisting mathematical research and discovery, with discussions also touching on OpenAI’s related progress.
