OpenAI says a new internal artificial-intelligence model has resolved more than 100 long-standing open problems across multiple areas of mathematics, a claim that, if independently verified, would mark one of the most significant developments in the use of AI for fundamental research.
The company, in announcements reported on 22 September 2026, has also claimed that the system solved the Navier-Stokes problem, one of the seven Millennium Prize Problems designated by the Clay Mathematics Institute. OpenAI said training of the model began on 28 August.
However, the company has not yet publicly released the broader set of more than 100 claimed solutions for independent verification. Alongside the announcement, a new Advisory Group on Mathematics and Artificial Intelligence has been established to help evaluate and communicate such results.
An independent group of mathematicians
The advisory group, made up of prominent mathematicians, says it operates independently from AI companies, does not accept payment for its work and intends to publish its recommendations publicly. Its remit includes advising AI developers on how to interact with mathematical researchers and how to present and release potentially significant results responsibly.
The creation of such a group reflects the unusual challenges posed by AI-generated mathematical claims. Traditionally, new mathematical results are developed by researchers, written up in papers, circulated among experts and subjected to peer review before being accepted. The process can take months or years, particularly for complex proofs.
AI systems capable of producing large numbers of claimed proofs could overwhelm that process. Verification requires expert time, and the mathematical community must decide how to handle results produced by machines, how to attribute credit and how to ensure errors are detected.
Why Navier-Stokes matters
The Navier-Stokes equations describe the motion of fluids, from air flowing over an aircraft wing to water moving through pipes and blood circulating in the body. They are fundamental to physics and engineering, and are used extensively in simulations.
The Millennium Prize problem concerns whether smooth, physically reasonable solutions to these equations always exist in three dimensions, or whether they can develop singularities, points where the solution breaks down. Despite decades of effort by leading mathematicians, the question has remained open. The Clay Mathematics Institute offers a $1 million prize for a solution.
A claimed solution to a Millennium Prize problem is an extraordinary assertion. Only one of the original seven problems, the Poincaré conjecture, has been solved, by Grigori Perelman, whose work was verified by the mathematical community over several years. Clay's rules require that a proposed solution be published in a qualifying outlet and gain general acceptance in the mathematical community over time before a prize can be considered.
Caution is warranted
The history of AI in mathematics offers reasons for both excitement and caution. In 2025, AI systems from OpenAI and Google DeepMind achieved gold-medal-level performance at the International Mathematical Olympiad, demonstrating rapid progress in mathematical reasoning. AI tools have also assisted mathematicians in discovering new patterns and constructions.
At the same time, there have been episodes in which claims of AI-driven breakthroughs were overstated. In 2025, claims that an AI model had solved several open Erdős problems drew criticism after mathematicians pointed out that solutions already existed in the published literature, illustrating how easily apparent discoveries can turn out to be rediscoveries or errors.
Those experiences underline why independent verification is essential. Until the claimed solutions are published and scrutinised by experts, they should be treated as claims rather than established results.
