Wikipedia's Jacobian conjecture article now describes it as 'a disproved conjecture... discovered by Anthropic's large language model Claude Fable 5' — a remarkably rapid update for a peer-edited encyclopedia. The speed suggests either pre-existing community awareness of the counterexample verification process, or a deliberate editorial decision to acknowledge AI mathematical contributions without the extended deliberation typical of Wikipedia consensus-building. This sets a precedent for how Wikipedia handles AI-generated mathematical results going forward.
