OpenAI reports an autonomous disproof of Erdős's unit-distance growth conjecture

The model found a construction using tools from algebraic number theory; OpenAI released the proof and a companion paper by external mathematicians who checked and contextualized the argument.

What happened?

OpenAI reported that an internal general reasoning model disproved the longstanding conjectured n^(1+o(1)) upper-growth behavior for planar unit distances by constructing infinitely many configurations with at least n^(1+delta) unit distances for fixed delta>0.

Why it matters

Unlike benchmark progress, the event concerns a longstanding open problem in active mathematics and an AI-generated argument judged substantive by independent experts.

Significance rationale: A substantive AI-generated disproof of a longstanding Erdős conjecture is a historical AI4Math milestone because the central contribution is new mathematics rather than benchmark performance or a general model release; the H1 designation does not itself assert independent verification.

Sources & artifacts

Verification history

  • 2026-05-20 · Partially verified · E3 · Inspectable artifact

    The Chronicle records this event from the cited primary or official source; the status does not imply independent Chronicle verification.

  • 2026-05-20 · Partially verified · E3 · Inspectable artifact

    OpenAI released the AI-generated proof together with a companion paper by nine external mathematicians describing a human-verified, digested version of the argument. Will Sawin independently published a stronger explicit lower bound building on the new construction. These sources materially strengthen the mathematical evidence while the Chronicle retains the human editorial gate for `independently_verified`.

  • 2026-09-10 · Independently corroborated · E3 · Inspectable artifact

    Under the Chronicle's event-level verification semantics, the nine-mathematician human-verified companion paper and Will Sawin's independent follow-up work substantively corroborate the core event description. This label records independent corroboration of the event and its public evidence trail rather than a Chronicle adjudication of ultimate mathematical correctness.
