  "account": "Anthropic researcher Levent Alpöge has claimed that the company's AI model Claude Fable 5 assisted in disproving the 87-year-old Jacobian conjecture. On X (formerly known as Twitter), Alpöge announced, \"Hello there, the Jacobian conjecture is false.\" If verified by the broader mathematical community, this discovery would overturn the longstanding conjecture, which has eluded proof or disproof for decades. The AI-assisted breakthrough demonstrates how artificial intelligence is increasingly being employed to make novel mathematical discoveries, rather than merely aiding in proofs.",
  "summary": "An Anthropic researcher used the AI model Claude Fable 5 to find a counterexample. This discovery challenges the 87-year-old Jacobian conjecture in mathematics. The AI-assisted finding reportedly offers a simple counterexample for verification. The conjecture, proposed in two dimensions, was extended to all dimensions later. This AI breakthrough highlights its growing role in mathematical…",
