OpenAI says an internal model resolved 100+ long-standing open problems in 24 days of training; no list released
On 21 Sep 2026 OpenAI said an unnamed internal model had resolved more than 100 long-standing open problems during about 24 days of training (28 Aug – 21 Sep). It released no list and no proofs, and did not define 'resolved'. It also formed a 9-member Advisory Group on Mathematics and AI at IAS Princeton, including Timothy Gowers, Edward Witten and Martin Hairer.
Key facts
- Claim: 100+ open problems resolved in ~24 days of training; no evidence released as of 29 Sep 2026
- Advisory Group on Mathematics and AI (9 members) at the Institute for Advanced Study; per its own announcement (Tao blog) it formed after OpenAI approached members, but it is independent of any AI company and unpaid
- Sober counterpoint: Epoch's 'FrontierMath Erdős' benchmark (68 open Erdős problems, Lean, $300/problem): GPT-6 Astra 3%, all others 0% (arXiv 2609.25050)
- OEIS Open benchmark: models resolved 147 of 492 formalised open OEIS conjectures (30%) at $50/attempt (arXiv 2608.11941)

What happened
OpenAI made a sweeping claim about a model still in training while announcing an advisory body of leading mathematicians.
Why it matters
If substantiated, it would mean open problems are being resolved at industrial scale. Until a list and proofs appear it is an unverified claim, and it contrasts with independent benchmarks where most open Erdős problems still resist all models.
