Not evaluated
Erdős’s short Egyptian-fraction conjecture (family 025)
The gist
On October 6, 2026, OpenAI published a manuscript, from an unreleased internal model, on Erdős’s short Egyptian-fraction conjecture.
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
An Egyptian fraction is a sum of fractions with numerator 1 whose denominators are all different; Erdős’s conjecture in the title concerns so-called “short” expressions of this kind. If the manuscript were correct, it would provide a result on this conjecture.
What remains unclear
The Lean (a language in which a computer checks every step of a proof) is supplied by OpenAI alone, and no verification by a third party is recorded. The sources read do not say where the question stood before the announcement.

The result is declared neither right nor wrong.
To move to “Under review”: a public review under way. To “Peer reviewed”: a journal publication or a review by named experts.

Method
The manuscript “Short Egyptian fractions” is dated September 25, 2026. OpenAI supplies lean/docs/025.md, which describes the scope of the Lean formalisation, and two Comparator statements (lean/ComparatorChallenges/EgyptianFractions.lean and lean/ComparatorChallenges/ShortEgyptianFractions.lean); formalization.yaml carries “review: status: unchecked”. history.md reports no revision of the 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: “describes the scope of the Lean formalization”).
Limits
No named third party: the recorded checks come from the claimant or from a platform tool. The claimant supplies a Lean proof; as of this date, DiscoverIA has found no independent verification of this proof or of the result.
