To understand

Analogy

Like a candidate who sits the paper at home and has it marked by former prize-winners of their own choosing, outside the official jury.

What it changes

If the score holds, a language model would have reached gold-medal level at the international mathematics olympiad (IMO). The proofs written by the model are published, so they can be read and checked.

What remains unclear

According to Euronews, OpenAI evaluated its model on the 2025 problems and published its results before any official verification: the grading came from three former IMO medallists not named in the announcement. A Google researcher disputes the marking scheme applied to OpenAI; this is not confirmed.

Method

According to Alexander Wei's announcement, quoted by Simon Willison, three former IMO medallists graded each proof independently, and the marks were settled unanimously. The model's proofs are in the aw31/openai-imo-2025-proofs repository. Status “not evaluated” recorded on 11 October 2026 from euronews.com (seen only in a search engine snippet).
