Not evaluated
The weak inhomogeneous Duffin–Schaeffer conjecture (family 022)
The gist
On October 6, 2026, OpenAI announced a result on the “weak inhomogeneous” Duffin–Schaeffer conjecture, from an unreleased internal model.
DiscoverIA status on October 12, 2026: not evaluated, meaning no third-party evaluation found.
AI draft, not reviewedWhat has not been reviewed?

What it changes
The Duffin–Schaeffer conjecture concerns the approximation of real numbers by fractions. If the manuscript were correct, it would bring a new result for this variant.
What remains unclear
No Lean proof (checkable by computer) is supplied for this family, and no third-party assessment is recorded. The sources read do not say which precise statement the manuscript claims.

Method
The openai/math repository contains one manuscript, “The Weak Inhomogeneous Duffin–Schaeffer Conjecture”, dated September 25, 2026. The absence of Lean is inferred from the absence of a lean/docs/022.md file; history.md reports no revision of this manuscript. 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.”).
