OpenAI says 10,000 AI agents cracked a 90-year-old fluid dynamics puzzle in 88 hours

Summary:
  • OpenAI says it is sharing a solution to the Navier-Stokes problem using a new in-house model and a system of coordinated software agents.
  • The team says the winning group ran at about 10,000 agents concurrently and produced its result on Saturday, September 5, roughly 88 hours after the first agents launched.
  • NYU mathematician Tristan Buckmaster questioned the path to the result and potential data exposure, while the Clay Mathematics Institute has not yet commented.

What OpenAI announced

OpenAI, the company behind ChatGPT, said Tuesday it is sharing a solution to the Navier-Stokes problem, a famously hard question about how fluids behave. The company credited an internal AI model working through a network of coordinated agents. These agents could read from a cached snapshot of the internet and execute code, and they were split into teams that could communicate within each group.

How it worked and when it happened

OpenAI said it organized agents into groups of varying sizes, and the group that ultimately produced the Navier-Stokes result ran with roughly 10,000 agents working at the same time. According to the company, the agents reached their conclusion on Saturday, September 5, approximately 88 hours after the first agents started running.

The push began on Sept. 1 after the company heard a rumor that someone had made headway on the problem, which it later learned referred to work by Levent Alpöge and Tristan Buckmaster. OpenAI said neither its researchers nor its agents saw any of that work before it was made public, and that no specific user data was accessed to solve the problem. It added that, while it considers it unlikely, de-identified data derived from their use of OpenAI products may have helped improve its models.

Pushback from mathematicians

Tristan Buckmaster, a mathematics professor at New York University, said he and Levent Alpöge of Anthropic have been collaborating personally on several math problems, including Navier-Stokes. Buckmaster wrote that Alpöge received tips suggesting information about their progress had been relayed to OpenAI, and he argued the path OpenAI described resembled their own, which he said is not a direction one reaches in just a few days by handing the problem statement to a model. He also raised the possibility that OpenAI's systems might have been trained using their Codex sessions or permitted to access them, noting they used several large language models during their work.

"I would like to be clear about what I am not claiming. I have not seen OpenAI's proof. I do not know what their model did, or how. I do not know whether our data was used," he added.

Why the prize context matters and what it means for your money

The Clay Mathematics Institute designated Navier-Stokes as one of the seven Millennium Prize Problems in 2000, with each offering a $1 million reward. The institute says the prizes were conceived "to elevate in the consciousness of the general public the fact that in mathematics, the frontier is still open and abounds in important unsolved problems; to emphasize the importance of working towards a solution of the deepest, most difficult problems; and to recognize achievement in mathematics of historical magnitude." Other headline problems on the list include the Birch and Swinnerton-Dyer Conjecture and the Riemann Hypothesis. The institute has not yet weighed in on OpenAI's claim.

For your wallet, here is the practical bit: frontier AI is moving fast, and breakthroughs can show up before the referees have blown the whistle. That mix often means sharp swings in sentiment and a lot of chatter before clarity arrives.

Are We in a Recession? 5 Threats to the Economy and Where the Money Is Moving
  • The S&P 500 is up about 13% this year, but without AI it's in a bear market, with nearly 40% of its companies down more than 20% for four months or longer.
  • Jackson, Briefs Finance's head of investing research, sees five threats: rising interest rates, sticky inflation, an economy propped up by AI, a struggling UK, and high oil prices.
  • The opportunities he's watching mostly sit outside the dollar: rising economies like Brazil and Indonesia, US-backed emerging market bonds paying 7% to 9%, and the shifts that fear creates.

Common Investing Mistakes: Why a Stock Grade Is One Tool, Not the Whole Toolkit
  • The Briefs Score shows growth, income, and wealth preservation investors how well a stock fits their goal, with a separate letter grade for each one.
  • The most common mistake is treating the letter as an instruction. An A tells you a stock scores well for one goal, not that you should buy today.
  • Research works best as one input in a process you own. The grade shows how a stock stacks up. You supply the goal, the timeline, and the rules for being wrong.

  • The same stock can score an A- for one goal and a D- for another, so picking your goal comes before picking any stock.

Is This Stock a Good Buy? How to Use the Briefs Score to Tell If a Stock Fits the Way You Invest
  • The Briefs Score shows growth, income, and wealth preservation investors how well a stock fits their goal, with a separate letter grade for each one.
  • One stock can score very differently for each. Nvidia showed an A- for growth and a D- for income, because it grows fast and pays almost no dividend.
  • Seven sub scores under each grade show what earned the letter, so you can see exactly where a stock is strong or weak for your goal.

How to Tell an Asset From a Liability: The One Question to Ask Before You Buy Anything
  • The typical American household earned more in 2025 than in any year on record, yet only 30% of Americans say they could pay a surprise $1,000 bill from savings, so the problem isn't income but what the income gets spent on.
  • An asset puts money in your pocket and a liability takes money out, and the wealthy buy assets first, then let the assets pay for the fun stuff.
  • Before you buy anything, ask one question: does this put money in my pocket, or take money out of my pocket? Then you need a plan for the money you keep.

How to Build Your First $2,000 Emergency Fund and Wipe Out Every Debt Over 10%
  • Your first money goal isn't investing, it's $2,000 in its own account named Do Not Touch, built by moving 10% of every paycheck into it automatically.
  • More than a third of American adults couldn't cover a $400 surprise bill with cash or savings, according to the Federal Reserve, and that's how one bad day turns into years of credit card payments.
  • Once the $2,000 is there, attack every debt charging more than 10% interest, highest rate first, because you can't out-invest a 22% credit card so paying it off is the investment.
