What Happened
OpenAI claimed this week to have solved the Navier-Stokes problem using AI tools. The problem is one of seven Millennium Prize problems, each carrying a US$1 million reward for a verified solution, and had gone unsolved for decades.
Melbourne-born Tristan Buckmaster, a professor at New York University, found himself at the centre of the dispute that followed. Speaking to the ABC, he was direct about what the development means for academic mathematics: "I think it's pointless. Like, I think the game is up."
OpenAI pushed back on suggestions that Buckmaster's prior work had fed into the result. The company said: "We can say categorically that it is impossible for Dr Buckmaster's Codex prompts over the last two months to have influenced the system in any way, including training."
The company also disclosed further work in progress. In a statement, OpenAI said: "In addition, since the completion of Navier-Stokes we have made substantial progress on another Millennium Prize problem. We are working through how to share these results thoughtfully."
Buckmaster did not hold back on his view of how OpenAI handled the announcement. "They have zero respect for the scientific community. I mean, it's appalling, honestly," he told the ABC.
Why It Matters
The dispute cuts to questions that the academic community has not yet resolved. As Buckmaster put it: "What do we do about credit? What do we do about hiring? What do we do about PhDs?"
Those are not abstract concerns. If AI systems can now work through problems that have stumped researchers for decades, the structures that organise mathematical careers, from PhD programmes to publication credit, face pressure that existing norms were not built to handle.
Buckmaster also raised a concern specific to Australia. "Australia needs to think about protecting our own national interests in this world where the resources are so skewed," he said. His point was that the capacity to solve these problems now sits inside a small number of privately owned foreign companies, not in public institutions or universities.
Key Details
Buckmaster described the AI's capacity in terms that capture why he sees the race as over: a "whole team of PhD students that don't need to eat and don't need to sleep." That framing points to a straightforward resource asymmetry. No university department can match the compute and iteration speed that a large AI lab can bring to a problem.
His response is not to compete but to reconsider the field itself. "I think it's more important to re-evaluate what math is," he said.
OpenAI's disclosure that it has already made "substantial progress on another Millennium Prize problem" suggests the Navier-Stokes result was not a one-off. The company said it is working through how to share those results, though it gave no timeline.
Background and Context
The Navier-Stokes equations describe how fluids move. A formal proof of the existence and smoothness of solutions in three dimensions has been an open problem in mathematics for decades and sits on the Clay Mathematics Institute's list of Millennium Prize problems. Each problem on that list carries a US$1 million prize for a verified solution.
Buckmaster's own research has been in the area of fluid dynamics and partial differential equations, which placed him directly in the path of OpenAI's claim and the scrutiny that followed.
The Guardian reported on OpenAI's initial claim on 8 September 2026, before Buckmaster gave his account to the ABC three days later.
What Comes Next
Buckmaster said he intends to step back from the race to publish breakthroughs. Whether the broader mathematics community follows that lead, or whether institutions find ways to adapt credit and hiring structures, remains to be seen.
OpenAI has indicated further Millennium Prize announcements are coming. The company said only that it is "working through how to share these results thoughtfully," without specifying which problem it has made progress on or when it will publish.
For Australian universities and research funders, Buckmaster's warning about national interests and skewed resources is now on the public record. Whether policymakers respond is a separate question.
