The site's wording is Conjecture 1 of Erdős and Simonovits (Combinatorica 2 (1982), p. 276), "For every finite $\mathbf L$ (containing bipartite graphs as well) there exists an $L^*\in\mathbf L$" with display (5), read with its two sides interchanged as the source page records; it states no exception. It fails at the two-member family of the two-edge star $K_{1,2}$ and the two-edge matching $2K_2$: for $n\geq2$ the joint extremal number is $1$, while each member's grows linearly (Known Results gives the check). The defect is already in the printed conjecture, not the site's. The site's curator, Thomas Bloom, reads the conjecture past that family. The commentary (page last edited 31 August 2026) reports Hunter's "folklore counterexample", a star and a matching "both with at least two edges", with $\mathrm{ex}(n;\mathcal{F})\ll1$ and $\mathrm{ex}(n;H_i)\asymp n$, and continues "This conjecture may still hold for all other $\mathcal{F}$"; it then credits the disproof to an internal model at OpenAI, pointing to the remarks under Problem 575, and the label DISPROVED (LEAN) records that disproof, whose family contains neither a star nor a matching. No curator post appears in the thread. The change inserts "other than those of the form $\{H_1,H_2\}$ where $H_1$ is a star and $H_2$ is a matching, both with at least two edges" after "for every $\mathcal{F}$", in the commentary's words; nothing else changes. The printed wording is answered no by the star-and-matching family: post 124 of the thread (19 August 2025, the account zach hunter) and Wigderson's note (p. 1, Observation, crediting Jordan Lefkowitz and reporting Simonovits's private communication that such counterexamples had long been known). That result answers the printed wording (every finite family), not the corrected Statement (every family other than a star with a matching), so it does not count toward the problem's standing; it is recorded as a rejected claim page (Wigderson, 2022). The corrected Statement is answered no by Theorem 1.1 of Chapter 10 of OpenAI's 2026 report, a family of connected bipartite graphs each containing a cycle, on its claim page (OpenAI, 2026). The commentary excludes only the two-member families: a family that adds to such a pair further members with at least two edges still has bounded joint extremal number, while each added member's own is unbounded, so it remains a counterexample. The page's standing judges the corrected Statement.
