Not evaluated
Classification of finite Euclidean Ramsey configurations (family 172)
The gist
On October 6, 2026, OpenAI announced a manuscript claiming a classification of finite Euclidean Ramsey configurations, 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?

To understand ≈ 20 s reading time, estimated
What it changes
A finite configuration is called Euclidean Ramsey if, for any finite number of colours, every colouring of a space of large enough dimension contains a congruent copy of it in a single colour. If the manuscript were correct, it would provide a classification of these finite configurations.
What remains unclear
The Lean (a language in which a computer checks every step of a proof) is supplied by OpenAI itself and marked “unchecked” in formalization.yaml. No third-party verification is recorded. 7 Comparator statements accompany a single manuscript, and the sources read do not say what they cover.

Method
The openai/math repository contains one manuscript, “A classification of finite Euclidean Ramsey configurations”, dated September 23, 2026. OpenAI attaches lean/docs/172.md and 7 files in lean/ComparatorChallenges, including EuclideanRamsey.lean and GrahamSpherical.lean. According to history.md, no revision is reported. 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.
