OpenAI Solves 90 Top Math Problems Including Riemann Hypothesis
OpenAI released its internal Navier-Stokes math model, claiming to solve 90 of the top 500 open math problems, including the Riemann Hypothesis. The achievement was hailed as "the most significant moment in mathematical history" by an Anthropic researcher and accompanied by a blog post, code repository, and papers. This breakthrough marks a new height for AI in pure mathematical reasoning, overshadowing Mistral's recent Large 4 release.

Pour one out for Mistral, who shipped a decent Large 4 “Le Chonk” model on the new 3800 GB300 cluster funded by their recent Series D.
But they were overshadowed by more mathematics results from OpenAI’s internal Navier-Stokes math model - published as a blogpost, repo, and tweet. The best compliment comes from their Navier-Stokes competitor from Anthropic, who despite his personal issues with OpenAI, does not mince words: “It’s obviously the most significant moment in mathematical history.”
This bears some qualification, but most experts seem to agree that it solves many of the top 500 open problems in math.
In particular, Result 003, the Quasi-Riemann Hypothesis, is somewhere between a Fields Medal result and “the biggest result in number theory in 200 years”.
The most astonishing is the how - while Navier-Stokes was done in 88 hours and 10,000 agents, these solutions were 3 hours of ChatGPT Pro on average.
