Report: Unreleased OpenAI Model Solved 100+ Open Math Problems in 24 Days

Multiple Reddit users (ConfidentSalt8108, BilelKort, haider1) relay a passage from an OpenAI page titled "Advisory Group on Mathematics and AI": an unreleased internal model, which began training on August 28, solved over 100 long-standing open problems across nearly all areas of mathematics within about 24 days. The model was also previously linked to work on the Navier–Stokes Millennium Problem, reportedly surprising even OpenAI internally. DeepMind's Seán Ó hÉigeartaigh cited the same claim twice, noting that mathematics—and soon science itself—is being transformed, and asking when external experts will get access to evaluate the model. All details remain second-hand.

Confirmed

• Posts m1, m2 and m3 consistently relay the original claim: training started August 28; 100+ open problems solved in 24 days.
• DeepMind's Seán Ó hÉigeartaigh (m4, m5) publicly amplified the claim, adding credibility from a leading AI lab.
• The model is internal and unreleased.

Unconfirmed

• The original page content and details are second-hand (acknowledged by m3's author haider1); no direct OpenAI announcement exists.
• The specific problem list, verification methods, and peer-review status of any proofs are unknown.

Why it matters

• If true, it would mark an order-of-magnitude leap in AI capability on frontier mathematics, far beyond public models.
• A DeepMind member's amplification and his question about external evaluation (m5) highlight industry concern over verifiability and open assessment.
• The event may also signal OpenAI assembling a math-and-AI advisory group, paving the way for scientific-reasoning products.
