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

The Jacobian conjecture has bedeviled math experts for nearly 90 years.

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

An AI called Claude Fable 5 has produced a counterexample that appears to disprove the Jacobian conjecture, open since 1939. The maths is short enough to check by hand. The story…

Anthropic’s Fable 5 found a 216-character counterexample to the Jacobian conjecture, an 87-year-old maths problem. Experts are split on what it means.

Anthropic's Levant Alpöge, a former Harvard valedictorian, used Claude's Fable 5 to find something that mathematicians have failed to since 1939.

Claude Fabel 5 disproved the Jacobian conjecture over the weekend, landing days after the capabilities of China's Kimi AI became the biggest force moving bitcoin markets.
