What this story says
- OpenAI claims an internal AI model has solved the Navier-Stokes existence and smoothness problem, a Millennium Prize Problem with a $1 million reward.
- The company stated that around 10,000 AI agents worked for 88 hours to produce the solution.
- Mathematicians are reportedly skeptical of the claim, citing the absence of a publicly available proof.
- Some reports suggest a dispute over credit and potential impropriety involving mathematicians Tristan Buckmaster and Levent Alpöge.

Artificial intelligence company OpenAI announced on 5 September 2026 that an internal, unreleased AI model has produced a solution to the Navier-Stokes existence and smoothness problem. This is one of the seven Millennium Prize Problems, established by the Clay Mathematics Institute, with a $1 million prize for a confirmed solution. OpenAI stated that approximately 10,000 AI agents worked in parallel for 88 hours to generate the solution. The problem, which has remained unsolved for about 90 years, concerns the behaviour of fluids and gases.
Disagreement over proof and prior work
Mathematicians have raised questions and expressed skepticism regarding OpenAI's claim, primarily because a proof has not been publicly disclosed. Some reports indicate that mathematicians Tristan Buckmaster and Levent Alpöge were working on similar research with AI assistance. According to some accounts, OpenAI's team became aware of this work and raced to complete their own solution. UOL reported that Buckmaster alleged OpenAI's internal team used a company model to solve the full Navier-Stokes equations, possibly after learning of his team's methods. UOL also reported Buckmaster's claim that OpenAI pressured him to remove Alpöge, who works for a competitor, as a co-author. OpenAI denies having had contact with Buckmaster and Alpöge's work before its own public announcement.

How each side covered it
Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.
Left
10 rated outlets
- Left-rated reports led with the potential controversy and accusations of impropriety surrounding OpenAI's announcement. Axios reported that OpenAI's "historic math solution overshadowed by credit controversy" and that "the company denies any ties to other research." Wired stated that the "landmark announcement by the frontier AI lab has been overshadowed by accusations of impropriety." Scientific American noted that "AI may have just solved a million-dollar math problem" and compared the feat to IBM's Deep Blue beating Garry Kasparov in chess, suggesting the field "will never be the same." Newser reported that the problem "may have just met its match, and the solver apps to be artificial intelligence."
Centre
9 rated outlets
- Centre-rated reports focused on OpenAI's claim of solving the problem and the scale of the AI effort involved, while also acknowledging the lack of public proof and the existence of prior research. NewScientist reported that "OpenAI has solved the Navier-Stokes Millennium problem using $15m of AI effort," noting that the result was announced amid rumours of similar, less complete work. Nature stated that "OpenAI claims huge maths breakthrough on a famed ‘Millennium Problem’," but added that the company "says it has cracked the physics of fluids using AI." Quartz reported that "OpenAI AI solves Navier-Stokes Millennium Prize Problem" and that "rivals contested OpenAI's account of events before the proof was published." Yle reported that "Open AI Claims to Have Solved One of the Mathematical Mysteries of the Millennium" but stressed that "the solution is only a proposal and has not been confirmed by the mathematical scientific community."

10 rated outlets
- Right-rated reports highlighted OpenAI's claim of a breakthrough and the technical details of the AI's involvement, with some noting skepticism. Anadolu Ajansı reported that "OpenAI says AI model solved one of mathematics' Millennium Prize Problems," adding that the "unreleased model took 88 hours, used up to 10,000 AI agents to solve Navier-Stokes problem." Firstpost News asked, "Has OpenAI model solved 80-year-old Navier-Stokes problem? Mathematician raises questions," and noted that "the underlying proof has not been made public." Latestly reported that "OpenAI AI Agents Solve Navier-Stokes Problem? AI System Claims Breakthrough in Mathematics," and that the proof "reportedly used around 10,000 AI agents over 88 hours." BioBioChile reported that "The AI Solved in 80 Minutes an Ancient Mathematical Problem that Expert Failed to Solve in 7 Years," though this appears to refer to a different problem than Navier-Stokes.
Questions about this coverage
- How did the left and right cover OpenAI claims AI solved Millennium Prize math problem?
- Of the 29 outlets on this story carrying a published leaning rating, 35% are rated left, 30% are rated centre, 35% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 61. The sections above set out what each side emphasised, in its own terms.
- Is OpenAI claims AI solved Millennium Prize math problem left or right?
- Neither side dominates it. Of the 29 rated outlets on this story, 35% are rated left, 30% are rated centre, 35% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
- Is the coverage of OpenAI claims AI solved Millennium Prize math problem biased?
- OpenAI claims AI solved Millennium Prize math problem is one event reported by 61 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
- Which outlets covered OpenAI claims AI solved Millennium Prize math problem?
- 61 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
- What is the Navier-Stokes existence and smoothness problem?
- The Navier-Stokes existence and smoothness problem is one of the seven Millennium Prize Problems, with a $1 million prize offered for its solution. It concerns the mathematical description of the movement of fluids and gases, and has remained unsolved for approximately 90 years.
- What does OpenAI claim to have achieved?
- OpenAI claims that an internal, unreleased AI model has produced a solution to the Navier-Stokes existence and smoothness problem. The company stated that around 10,000 AI agents worked for 88 hours to generate this solution, which it announced on 5 September 2026.
- Why are mathematicians skeptical of OpenAI's claim?
- Mathematicians are reportedly skeptical because OpenAI has not publicly disclosed the proof of its claimed solution. This lack of verifiable evidence has led to questions about the validity of the announcement, especially given the problem's significance and the substantial prize money involved.
- Is there a dispute over credit for the solution?
- Yes, some reports suggest a dispute over credit. Mathematicians Tristan Buckmaster and Levent Alpöge were reportedly working on similar AI-assisted research. One account claims OpenAI's team learned of their progress and raced to complete their own solution, with allegations of pressure to alter co-authorship.
