Claude Fable 5 generated the polynomial map used as the 2026 Jacobian conjecture counterexample
Without evidence. The post is first-party testimony: it thanks "fable" for working during the match and gives the polynomial, but offers no transcript, no model version and no description of the prompting. The text was read through several sources that quote the post in full; the post itself could not be opened directly. Sep 13, 2026

hello there the jacobian conjecture is false thanx to my close friend akhil for asking about it and my other close friend fable for working during the world cup final ((1+xy)^3 z + y^2 (1+xy) (4+3xy), y + 3 x (1+xy)^2 z + 3 x y^2 (4+3xy), 2 x - 3 x^2 y - x^3 z): \C^3\to \C^3
