OpenAI claims new model solved 100+ open math problems and Navier–Stokes

On September 22, an OpenAI announcement quickly spread through the AI and math communities: according to circulating information, a new internal model that only began training on August 28 has already solved more than 100 long-standing open problems spanning most fields of mathematics, and claims to have cracked the Navier–Stokes Millennium Prize problem. The model's pace of mathematical progress reportedly surprised even OpenAI's in-house mathematicians. The claim has not been peer-reviewed or independently verified, various retellings differ in the details, and it should currently be treated as an unverified OpenAI assertion.

Confirmed

• OpenAI released an announcement related to frontier mathematical capabilities, relayed by multiple accounts including @DrSingularity and @gaganghotra.
• The announcement involved a new internal model that started training on August 28 and claims to have solved over 100 open math problems plus the Navier–Stokes problem.

Unconfirmed

• The "100+ open math problems solved" claim first surfaced via third-party accounts; @Polymarket noted the details remain to be verified, and some posts (such as the Reddit post shared by @filterdust) suggest the announcement itself focused on mechanisms like forming an advisory group, so the "100 problems" claim should be treated with caution.
• Whether the Navier–Stokes Millennium Prize problem has truly been solved has no independent verification; even @DrSingularity's post labeled it only as "claimed" and "circulating."
• Multiple posts give inconsistent timelines such as "24 days" vs. "28 days."

Why it matters

• If true, AI's capability in pure mathematics research would take a qualitative leap; @DrSingularity even called it a "singularity moment" for mathematics.
• The math community expressed concern over the development, and OpenAI subsequently announced an independent math advisory group, showing that trust between frontier AI capabilities and the academic community is becoming a governance focal point.
