OpenAI solves geometric problem dating back to 1946
OpenAI's latest reasoning model claims to have disproven a geometric hypothesis that has remained unsolved since 1946. This has been confirmed by the same mathematicians who previously challenged OpenAI's claims.

What happened?
With its latest reasoning model, OpenAI has succeeded in disproving a geometric hypothesis that has remained unsolved for 80 years. The hypothesis, formulated in 1946, has previously challenged mathematicians globally. This was announced on 20 May 2026 in TechCrunch AI.

”OpenAI claims its reasoning model disproved a geometry conjecture unsolved since 1946 — and this time, the mathematicians who exposed its last embarrassing claim are backing it up.”
Why it matters
Solving a long-standing mathematical problem, particularly in geometry, indicates progress in AI's ability to perform advanced deductive conclusions and reasoning. It demonstrates the potential for AI to assist or even drive research in complex scientific fields. Previous claims from OpenAI have been criticised, making the current confirmation from independent mathematicians particularly noteworthy.
Who is affected?
This primarily affects mathematicians and researchers in AI and computer science, as it demonstrates new possibilities for AI in scientific discovery. Users and companies relying on advanced AI models can expect future applications that benefit from improved reasoning capabilities. The general public may also be indirectly affected, as breakthroughs in fundamental research often lead to broader technological advancements.
What else you should know
The mathematicians now confirming OpenAI's achievement are the same individuals who previously questioned one of their claims, which strengthens the credibility of the statement.
