A mathematician at Anthropic used its large language model Fable 5 to find a counterexample to the Jacobian conjecture, a longstanding problem in algebraic geometry.

This simple yet groundbreaking result challenges the conjecture for dimensions greater than two and highlights AI's potential to revolutionize mathematical discovery.

The counterexample, fitting into a single social media post, was quickly verified by peers, marking a significant shift in how mathematicians approach complex problems.The incident underscores AI's growing role in academia, prompting reevaluation of traditional methods in fields like mathematics.
