Not evaluated
A counterexample to Pixton's original completeness conjecture (family 053)
The gist
In its release of October 6, 2026, OpenAI presents a manuscript, from an unreleased internal model, that would give a counterexample to Pixton's completeness conjecture.
DiscoverIA status on October 12, 2026: not evaluated, meaning no third-party evaluation found.

What it changes
If the manuscript were correct, Pixton's original completeness conjecture would be false. The manuscript's title speaks of a "high-arity" counterexample in the Chow setting.
What remains unclear
No third-party assessment is recorded, and OpenAI supplies no Lean proof (checkable by computer) for this family. The sources read do not say where the question stood before the announcement.

Method
The openai/math repository attaches a single manuscript to family 053, "A high-arity counterexample to Pixton completeness in Chow", dated September 24, 2026. The absence of Lean is inferred from the absence of lean/docs/053.md; history.md reports no revision. DiscoverIA status: not evaluated, meaning that no third-party evaluation has been found in the sources read. Set on October 12, 2026 from github.com (page read, quotation checked word for word: “Not all have accompanying Lean formalizations.”).
