A nighttime science-fiction scene shows a researcher surrounded by papers, equations and books, facing a massive technological structure that pulls information into a blue vortex.

An artificial intelligence system can produce an extraordinary mathematical proof and, at the same time, trigger a crisis over the data that may have made it possible: the controversy between OpenAI and the mathematicians Tristan Buckmaster and Levent Alpöge forces us to look beyond the result: what happens when the tool that receives unpublished research also belongs to a company capable of competing with its author?


The announcement that a “millennium problem” had been solved

On September 8, 2026, OpenAI claimed to have solved the “Navier-Stokes” problem through an AI model that is not yet public. It is not important for us to understand exactly what the “Navier-Stokes” problem means, but it is important to know that it is one of the millennium problems, seven major mathematical challenges selected in 2000 by the Clay Mathematics Institute that pose fundamental questions in mathematics that remain unresolved, and whose solution would have major consequences.

Of those seven problems, one, the Poincaré conjecture, was solved by the Russian mathematician Grigori Perelman, who presented his proof between 2002 and 2003.

The Navier-Stokes equations are another problem on that list (the Clay Mathematics Institute continues to classify the problem as unresolved, which is why I use the present tense): they are equations used to describe how liquids and gases move, from water flowing through a pipe, to air around an airplane, to blood flow. The problem to be solved is not whether those equations work in ordinary situations, but whether they always produce stable solutions or whether, under certain conditions, they can produce infinite values and, therefore, what is known as a singularity.

On September 8, OpenAI announced that it had solved them by deploying close to 10,000 agents. This means that thousands of instances of the same model worked in parallel and, while some tested strategies, others checked steps, tried to correct errors, or carried out whatever other process emerged as necessary as the attempted proof advanced. This is a computing capacity completely beyond the reach of any individual researcher.

As a result, OpenAI published a proof accompanied by a formalization in Lean, an automated verifier: it checks each logical step of a proof without relying on a human reviewer. That work is now entering a process of verification by specialists, but it has already set off several alarms.

The coincidence that gives rise to suspicion

Even before the announcement, Buckmaster, a professor at New York University, and Alpöge, a mathematician at Anthropic who was working on the project in a personal capacity, had been working on a solution to Navier-Stokes and were using several AI models in their work, including Claude and Codex.

Here is where the central problem begins: Buckmaster says that all drafts of the project had gone through his OpenAI Codex sessions, and that OpenAI’s system ultimately arrived at the same kind of proof problem on which Buckmaster and Alpöge had focused their efforts.

That “coincidence” does not prove that the data used by the researchers was used by the OpenAI agents that achieved the solution, but it is far from harmless: the company had potential technical access to a platform where those researchers’ unpublished work was stored. This led Buckmaster to ask OpenAI whether the model had been trained on his sessions or could access them, and he says the answer he received was that the system did not consult user data, but that he did not receive a direct answer about its training.

To complicate things even further, OpenAI accepted that it could not rule out that anonymized data derived from the use of its products had contributed to improving the models.

Privacy is not protection of ideas

The word anonymized often creates a false sense of calm; removing names, email addresses or other identifiers protects a person’s identity only partially, but it does not necessarily remove their work or their ideas. For a researcher, then, the main harm may not be that the system reveals who they are, but that it appropriates confidential work that improves its capacity to compete with the very research being developed, taking over the researcher’s intellectual effort.

This forces us to separate what is legal from what is private and from scientific integrity, because a generic clause authorizing the use of conversations to improve models is not the same as informed consent to turn unpublished research into a corporate commercial advantage.

Buckmaster wrote that he did not know whether his data had been used and that he was not accusing anyone of having done so, because there is not enough evidence to sustain the claim that OpenAI appropriated his work, but there is also no independent audit mechanism that would allow that possibility to be ruled out, and presenting the company’s denial as the end of the matter is unacceptable.

When cases like this appear, the researcher is usually asked to prove from the outside what happened inside a closed model, but that is an impossible burden for the researchers involved, because it is OpenAI that controls the training records, retrievals, internal prompts, model versions and communications of its team.

The absence of public proof of appropriation is not equivalent to proof of non-appropriation either: the company should affirmatively demonstrate that the process was isolated, which requires an external audit with confidential access to relevant records, the capacity to trace the first appearance of the central ideas, and the authority to verify whether materials from Buckmaster, Alpöge or their collaborators entered, through any channel, into training, product memory or the research process.

The dispute over credit makes the problem worse. Buckmaster says that OpenAI proposed that he present the company’s result without Alpöge (let us remember that he works at Anthropic) and that, when he announced that he would make the situation public, he received statements that he interpreted as a threat to his career.

The company responded through Sébastien Bubeck, a French-American mathematician and researcher specializing in artificial intelligence, who has worked at OpenAI since 2024 and was part of the team that produced the proof and held direct conversations with Buckmaster about publication, coordination and the allocation of credit for the mathematical finding. Bubeck maintains that he merely told Buckmaster that he considered it “improper” for an Anthropic employee to sign an OpenAI paper.

Conclusion: a red line for all human intellectual work

Navier-Stokes is an exceptional case because of the prestige of the problem, and two questions converge in it: the first is whether OpenAI researchers or its agents directly consulted Buckmaster and Alpöge’s conversations. The company denies this. The second is whether those conversations may previously have been used to train or improve the model, something OpenAI acknowledges it cannot rule out.

The conflict it raises extends to researchers, journalists, programmers, lawyers and even companies that upload sensitive documents into AI systems every day: if the platform is taking the information they produce to train models, it can appropriate their knowledge and experience and then compete with those who produced it, even if no record of who they were actually remains.

The underlying problem is not that a company deliberately “reads” other people’s sessions, but the absence of a verifiable technical separation between the use of a product and the training of models that compete in the same field as their users.

Neither the researcher nor an external regulator can currently audit whether anonymized data from a work session entered a training pipeline or not. This creates a vacuum that different regulatory frameworks, such as the European Union’s AI Act, have begun to address through transparency requirements for training data in general-purpose models, but without reaching the structural conflict of interest produced by the presence of a company that is, at the same time, the source of the tools and a competitor of its own users.

Systems intended for intellectual work should offer confidentiality by default, verifiable separation from training, records of provenance, understandable opt-out mechanisms and real avenues for redress. In high-impact scientific results, data and attribution audits should be as normal as the review of the actual proofs behind a finding.

The question of which human ideas entered the system, under what conditions and who has the right to benefit from them needs an answer based on verifiable actions, in which AI companies do not seem especially interested.

And, by the way, acceptance of authorship for the solution of a millennium problem represents, for its author, one of the greatest intellectual recognitions possible within mathematics and, as a detail, solving one of these problems means gaining access to a one-million-dollar prize and is, in this case, a door to the Nobel Prize in Physics, which grants just as much recognition and financial reward.
