Drama/accusation summary:

  • Aug 15th: Tristan Buckmaster & Levent Alpöge make progress on a few important math problems, "finite-time blowup with smooth forcing for incompressible porous media, for Boussinesq, and for 3d incompressible Euler."

  • they do NOT have a proof for the $1,000,000 Millenium Prize problem. BUT, they do claim to have a proof for a similar (non-Millenium) Navier Stokes problem that could help lead the way there

  • Levent works at Anthropic, but this research was independent of his work there, with a mix of GPT and Claude models. Tristan is not related to Anthropic.

  • Early Sep: Rumor spreads to OpenAI that Anthropic solved a major problem. Tristan emails OpenAI to clarify, without revealing the problem they solved or how they did it.

  • After hearing of the rumor, OpenAI started researching Navier Stokes with a new internal model.

  • Sep 6th: OpenAI's Sebastien Bubeck tells Tristan that they solved the $1,000,000 Millenium Prize Navier Stokes problem. The approach is very similar to Tristan & Levent's approach to the non-Millenium problem.

  • Tristan is suspicious of the timing, as only few others were trying this approach. OpenAI says the model didn't access his user data directly, but leaves unanswered whether Tristan's chat conversations were part of the training.

  • OpenAI says they would partially credit Tristan for the $1,000,000 discovery (even though Tristan did not solve the $1,000,000 problem) — but only if they remove Levent as an author, as he works for Anthropic.

  • Sep 8th: Tristan refuses to remove Levent, and rushes to publish their results independently.

"OpenAI says they would partially credit Tristan for the $1,000,000 discovery (even though Tristan did not solve the $1,000,000 problem) — but only if they remove Levent as an author, as he works for Anthropic."

This says it all. OpenAI knows their "proof" relied on Tristan's work via his conversations with their models.

u/SimiKusoni Sep 08 '26

Reading between the lines the model had been actively trained after the work had been added to Codex and OpenAI "cannot rule out that de-identified data derived from their usage of our products helped improve our models⁠."

Ignoring that it's pretty awful that they can't tell what the training corpus was for a specific model I think it's a fairly safe bet that the user's work was in that training data. The conversations described also portray them as being pretty desperate to downplay any human involvement in the work, even on their side and ignoring the question of provenance.

It seems like a pretty sad state of affairs either way that could have been trivially avoided by OpenAI keeping track of training data.

u/THE_FUZBALL Sep 08 '26

If they can’t tell what the corpus was and they are also training models based on user chats, doesn’t this open up the models to massive poisoning vulnerabilities? That’s like rudimentary security 101. It appears that either they would be vulnerable to such attacks, or they do have measures in place to control what is contained in corpus.

26

u/nonotan Sep 09 '26

You do realize pretty much all major LLMs are essentially trained on any and all data they can physically get their hands on? You can already poison the data by posting bullshit on here. It's possible that some sort of crude filter is in place to reject obviously malicious text, but as long as you keep it sounding loosely plausible and target something niche enough that it won't be overwhelmed by tons of inputs saying otherwise, it's going to work. They are vulnerable to such attacks, and will continue being vulnerable probably for as long as "LLMs trained on astronomical amounts of data" remains the approach of choice.

u/biscuitchan Sep 08 '26

but then it wouldn't be anonymized, no? a bigger problem

21

u/lauradorbee Sep 08 '26

It doesn’t de-anonymize anyone to be able to tell “were this user’s conversations in the set of data used to train this model?” - you know that it’s in there, not what part of it originated from what user. It would only be de-anonymizing if they had metadata attributing each message/conversation back to the user, i.e if they could answer “which user (in particular) did this piece of the training data originate from”.

32

u/SimiKusoni Sep 08 '26

Data being anonymised doesn't prevent it from being found after the fact. In this specific instance for example they know the user's working title for the paper, they could just search their dataset for it and find the training data. Or they could use any other uncommon strings from the work they put into codex.

Also as an aside de-identified data is not anonymised, it has an explicit meaning and they didn't just choose the unusual wording randomly. Genuinely anonymised data falls outside regulatory frameworks like GDPR or various state laws entirely, de-identified data does not because re-identification remains possible.

Given that OpenAI don't specify anywhere (in this blog post or other articles) exactly what they do to "de-identify" training data they may well have a hashed user ID sitting alongside the data to verify the source if they ever need it.

14

u/silva_p Sep 08 '26

It can be anonimized only one way, i.e. can't know who the data belongs to from the data alone but probably can see his chat history and confirm if it is there

u/TwistedBrother Sep 09 '26

It’s more that imagine there’s an idea that fits, like learning planes rise because of faster air on the top of a wing. A model doesn’t have to learn that more than a handful of times because it’s reinforced by all the other corroborating evidence.

Models don’t “average out” the things they learn, they built semantic structures topologically (as in shapes of ideas that work together). Some fragile ideas that aren’t (wait for it) load bearing might get forgotten way too quickly but some ideas that just settle all the others can persist through a lot of training.

If this idea was in a few conversations, and it fit (the forced Euler version) that might be the sort of thing that once exposed it settles many other uncertainties in the model such that any downstream model could draw upon that coherent ensemble of ideas.

u/usefulidiotsavant Sep 08 '26

The claim that a singe conversation (which, let's suppose, might have even contained the solution) in the training data latter allowed the model to reconstitute the proof is highly dubious.

A model the size of Astra trains on millions of curated conversations, billions of pages and trillions of tokens. A single conversation with the correct answer is essentially quantization noise and should have no measurable effect in any practical scenario where that same problem is involved.

On the other hand, OpenAI could be doing something much smarter that could affect the result, say, a RAG over similar conversations in the past, a self-evaluation of remarkable results that are marked or boosted etc.

If I had the smartest model in the world, as well as a database of the problems and approaches the smartest people in the world are playing with, it would be foolish not to connect the former with the latter and mine the dataset for low hanging fruits in scientific discovery. It's such an unfair advantage that the firm doing it will win in any area, forever.

In theory I agree, but in practice I've had an experience that made me doubt theory here. I asked Sonnet 5 about my own work, and it was able to pull the title and core idea of a petty little publication of mine with almost-zero citations, from model weights. That's something I very much did not expect. Granted, it's different from pulling a proof idea from a single conversation, but I would've expected it'd need a few orders of magnitude more training data.

16

u/Stock-Self-4028 Sep 08 '26

The same goes for my (currently unpublished as a paper yet) but not very significant result which I've fed to some of the previous GPT-5 series models (I don't remember if it was GPT 5.3/5.4 series or a newer GPT-5.5).

Anyways what I have been working on was least-squares fitting of trigonometric least squares method through Levinson recursion and NuFFT-1. Nothing groundbreaking, but it's a new computational complexity floor (more precisely superfast Toellitz solvers give the complexity floor, but Levinson recursion happens to be the most practical silver here) for that exact problem. Also I have code using that algorithm in four different public GitHub repositories to be clear.

Either way - older GPT models failed to derive that despite being relatively straightforward, new ones give you the right solution with absolutely no issues just as you ask them for the lowest computational complexity for that exact problem.

And now I am aware that the models are getting smarter, but I also see that as a clear training set "contamination".

And now I am not sure if either my chat with ChatGPT somehow got into training dataset, or if that exact solution got scraped from one of the GitHub repos I have uploaded the algorithm to.

Either way I am practically certain, that that exact algorithm somehow got into OpenAI's training dataset and GPT 5.6 has remembered it flawlessly.

u/usefulidiotsavant Sep 09 '26

Frontier models overtrain to the tune of 1000 tokens per parameter. So, while it's not implausible for certain pieces of training to have an outsized effect (perhaps, deliberately so), its impossible that the average recall for random piece of training material to be this good. Even the best imaginable compression can't recover hundreds of tokens from a single scalar.

5

u/faustianredditor Sep 09 '26

Right, but a single conversation can easily have thousands of tokens, recurring conversations even more. So you could easily have an allocation of a few tokens to the researchers' conversations, or similarly a token or three for my paper. Theoretically, of course.

u/MathAddict95 Sep 09 '26 edited Sep 09 '26

I think you would be surprised as to how good these LLMs are at learning even from a single data point. A document containing say a proof of NS is not a random piece of training material, rather its a data point of a very narrow domain in the corpus (not many data points would be discussions involving NS). As an extreme example, if your data was a collection of documents filled with random words (essentially noise), except for one special document containing "The proof of NS is" followed by random words, its plausible that the neural net would memorize the random words for the special document, simply because its likely the only document starting with "The proof of NS is", and so conditioning on this prior isolates the document precisely.

I got curious and tested this: I asked ChatGPT to recall a somewhat obscure paper from 2006. It could not recall exactly the algorithm used in the paper, but it was able to recall an important idea in its analysis. I know for a fact that this idea was used only once in literature (since I work in the field), and its also a niche topic, so it really should be the case that this idea appears once in the training data (or at the very least, a single digit number of times).

In contrast, Gemini 3.5 completely failed at recalling the paper. The gap is probably because ChatGPT is on a larger pre-train than Gemini.

We don't really know exactly how these LLMs learn, so it is really hard to rule out whether the independent researcher's data affected the model's trajectory significantly, even if it was one data point.

1

u/usefulidiotsavant Sep 10 '26

I'm not disputing the effects you mention, just raise the fundamental Shannon informational limit against verbatim recall, there is no mathematical way that a single 16 bit parameter could compress hundreds of tokens and allow perfect recall in the average case, as some commenters claim.

In your particular case, was that a paper with zero citations, or did maybe some of the citers rephrase the main approach in their introduction? Could we perhaps imagine a rational path to that approach with the vectors of related research aligning towards it, so that the model makes a "happy hallucination" that happens to match the actual approach, without actually encoding it? maybe aided by a few parameters the training did nudge in the right direction based on that paper? Was COT used, allowing some rational recreation? This would also explain the inconsistencies between models. Could we imagine quality research papers from this field be boosted somewhat in the training, in a way random conversations with customers would not be?

So not disputing it could happen, just questioning the fundamental information limits in the average case.

u/THE_FUZBALL Sep 08 '26

They will win until the community gets wise to it and stops leaking secrets to their service if they want to avoid their research being leaked.

I don’t understand how OpenAI could think this is a good move. If they are stealing IP from chats then it will eventually become clear that using their service is akin to pasting your solution to a public forum and expecting it not to be stolen. In fact that’s almost a better idea because then you have some kind of paper trail to prove your authorship. The only explanation is they think their product is so good that people will have no better option, but this is very short term gain pre-IPO strategy.

OpenAI specifically denied the RAG accusation.

I also agree with the others that the recall of minor details for these models is remarkable and we can’t rule it out.

3

u/ScottBurson Sep 09 '26

I think you're mistaken. I've seen another case where a single short piece of text in the training data popped out under the correct conditions.

It's true that a single update doesn't change any weight very much — but it can change many of them slightly.

1

u/amebix1221 Sep 10 '26

How so? Models have been shown to reproduce training data verbatim. And did OpenAI rule out the possibility that the data could have been available to the model in other ways?

1

u/redditter208475093 Sep 12 '26

Why? If the conversation is very niche and that's the only data relevant to the input, it will use that data. LLM are just very advanced autocomplete and it's not clear how much entropy is lost between the training data and the model. Frontier models are trillions of parameters.

118

u/purplebrown_updown Sep 08 '26 edited Sep 08 '26

Exactly. Not to mention OpenAI responded with threats like "Why would you ruin your career". Nobody who knows they're on the up and up would do that. What I believe actually happened is that OpenAI was aware of Buckmaster's progress and direction, got backdoor access to the conversations to get a preprint, and then used that information to claim they solved the problem on their own. It's the equivalent of stealing someone's manuscript and publishing before them and claiming credit or shared credit.

u/ImNotAWhaleBiologist Sep 08 '26

It’s just as impressive, if not more so, that someone used their model for such a solution and wasn’t affiliated. Seems appropriate to include all as authors, and can credit contributions accordingly.

Update from NYTimes:

The Wednesday evening statement from OpenAI was more emphatic: “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 statement added, “After investigating, we can say with full confidence that no user inputs past July 3rd could have influenced this system in any way.”

And also from Tristan Buckmaster that most of their work was also produced by AI models:

In their collaboration, Dr. Buckmaster set up the problem, and then Dr. Alpöge fed that into an A.I. model at Anthropic. Based on what came out, they provided further input and repeated the steps. The process worked well, but for Dr. Buckmaster, it became discouraging. “On one side it’s, like, super exciting to be part of this,” he said. “On the other side, this is frightening, because I felt like the A.I. had overtaken me.” Was he now an interpreter of A.I. slop and no longer the discoverer of new mathematical insights? “What’s the human part of it?” he said.

This is something I am really curious about: is OpenAI (and other AI providers) training their models on theirs users private and potentially unpublished work?

I am working on image generation using procedural algorithns in a somewhat novel way. I have been using ChatGPT for development. It's fairly low stakes, but the images look very different than pretty everything else. I tried getting a friend to see if he could get ChatGPT to guess how the image was produced and we did the same test with Claude as well.

ChatGPT knew pretty accurately how it was made. Claude had no clue. It's not a smoking gun, but pretty worrying if your private stuff is being made public through training before you get a chance to release it.

u/dramatic_typing_____ Sep 08 '26 edited Sep 09 '26

I've had this same experience with something 'novel' I did for rendering to a depth buffer with 3DGS scenes.

I HIGHLY suspect OpenAI does something shady such as creating derived data from your conversations and using it for training; that way they can still claim they don't directly use your data.

EDIT: Someone with access to a lawyer, please check me on this-
https://openai.com/policies/row-privacy-policy/

1. The Opt-Out is Specifically for Model Training The privacy settings allow you to opt out of having your content (like your ChatGPT conversations) used to "train the models." The policy states:

"As noted above, we may use Content you provide us to improve our Services, for example to train the models that power ChatGPT. Read our instructions on how you can opt out of our use of your Content to train our models."

2. Aggregated and De-Identified Data is Still Created and Used Even if you opt out of model training, OpenAI reserves the right to create derived, anonymized data from your personal data (which includes your User Content and conversations). The policy clearly states:

"We also aggregate or de-identify Personal Data so that it no longer identifies you and use this information for the purposes described above, such as to analyze the way our Services are being used, to improve and add features to them, and to conduct research."

Because this data is stripped of personally identifiable information (de-identified), OpenAI treats it as derived data and can use it to research how people use the tool and to develop new features, regardless of your model-training opt-out status.

3. "De-identified" removes who you are, not what you said When OpenAI (or almost any tech company) de-identifies data, they strip away Personally Identifiable Information (PII) like your name, account details, email, and IP address. However, the actual text of your prompt - the sentences describing your novel idea, business plan, or code - is the core data being processed. The de-identification process disconnects the idea from your identity, but the text containing the idea itself remains in their system logs.

did openai think this would be a win for them? seems like a lot of users of their products will now be more aware of how vulnerable their data is if not already aware. if ZDR gets called into question that must be bad for potential enterprise customers and another firm could capitalize and offer better guarantees

u/sciphilliac Sep 10 '26

Maybe I'm misreading the chatGPT TOS, but they are clear to collect the data you put in your prompts. From https://openai.com/policies/privacy-policy/:

> User Content: We collect Personal Data that you provide in the input to our Services (“Content”), including your prompts and other content you upload, such as files⁠(opens in a new window), images⁠(opens in a new window), audio and video⁠(opens in a new window), and data from connected services⁠(opens in a new window), depending on the features you use. Some of our Services allow you to interact with other users, such as post, comment, or send messages, and we treat those interactions as Content, too.

So yes, if you use ChatGPT for personal use, OpenAI keeps that data (mind you, I'm only referring to non-corporate licenses)

u/funky-chipmunk Sep 08 '26

OpenAI Employee

To truly prove some incidental usage data made no difference we'd have to (a) identify any of their de-identified data that came from their usage of ChatGPT, (b) train a bunch of expensive giant models, and (c) ask them all to solve the Navier-Stokes Millenium problem until hitting some level of statistical significance. It's just not feasible to run experiments like this to prove whether a piece of data has an effect on model behavior.

As a parallel example, can we prove the phase of the moon had no impact on the NS solution? No, not without a bunch experiments run at different phases of the moon.

There's no reason to believe that anything they did in ChatGPT led to our solution; it's just impossible for us to truly prove it. And knowing most of the recipes we use, there's really no reason to think such contamination is possible. I've asked the team to make a clearer, less-lawyerly statement here - let's see what happens.

My opinion: I think they are being needlessly obtuse and evading more. My guess is they shouldn't have to train models to check for contamination - just clarify what they were fed.

Why would it be impossible to prove it? Their conversation data is either in the training set or it's not. The model solution tokens can be gone through as well to see what it accessed and how it came at its solution

u/muntoo Researcher Sep 09 '26 edited Sep 09 '26

... can we prove the phase of the moon had no impact on the NS solution?

Experimental particle physicists cannot "prove" with 100% certainty that the discovery of the NS solution in 2026 had no impact CERN's discovery in 2012.

Nothing can be proven.

But, with some agreed upon prior model about how reality tends to work, scientists can come to a reasonable consensus that what I had for lunch today had no effect on the NS solution yesterday, which in turn had no effect on CERN's discovery in 2012.


it's just impossible for us to truly prove it.

Sure. But there is still evidence one can present. Preferably evidence that is statistically meaningful. Unless the solution to NS was once-in-a-lifetime fluke, which cannot be replicated with any significant probability, which would raise questions about the generalizability of LLMs being able to solve other problems in mathematics. (Which I don't believe is the case.)

You took the one sentence that sounds like they admitted they were wrong out of context. While I’m personally inclined to believe OpenAI stole the result, they certainly have not revoked their claim of original discovery, pretending otherwise only minimizes their attempts at stealing the spotlight.

> We (the researchers and the agents) did not see any of their work through any means until they released it publicly — in particular, no specific user data was accessed in order to solve this problem.

> While unlikely, we cannot rule out that de-identified data derived from their usage of our products helped improve our models⁠.

> However, our proofs differ significantly and even the precise results proved are different in the Euler case (forced vs unforced).

They even have an entire section titled “How we found the proof,” so I believe it’s fair to say they have not yet revoked their claim of original discovery, even though it’s dubious at best.

u/purplebrown_updown Sep 08 '26

The fact that OpenAI tried to offer shared ownership, but wanted to leave out Levent because he worked at Anthropic, reveals the whole game. They knew they stole the work, offered a compromise, threatened Brubeck - not something an ethical person would do.

u/funky-chipmunk Sep 08 '26

My point stands above yours - They would have outright been screaming at top of their lungs if there was no leakage.

Edit: They should use Astra to audit - It shouldn't be that hard.

u/Shizuka_Kuze Student Sep 08 '26

Actually, our points are orthogonal. I’m not denying leakage, in-fact I think it’s likely! I’m denying the fact they’ve revoked their claim, which is simply untrue.

1

u/elsjpq Sep 09 '26

I feel like this should be possible for OpenAI to test: take an older model with only data acquired before Tristan & Levent started working on it. Then try to solve Navier Stokes again with the old model. If it can't be solved with the old model, then OpenAI's result depended on Tristan's result.

3

u/MuonManLaserJab Sep 09 '26

That assumes incorrectly that Tristan's result is the only difference between the model they used and the previous one.

There were probably many small algorithmic differences, maybe some big ones, and of course different random starting weights resulting in entirely different final weights.

u/G_fucking_G Sep 10 '26

OpenAI has now completely dismissed the claims (NYTimes):

The Wednesday evening statement from OpenAI was more emphatic: “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 statement added, “After investigating, we can say with full confidence that no user inputs past July 3rd could have influenced this system in any way.”

To clarify, no "solution" to the equations has been found. The millenium problem is to prove or disprove the existence of smooth solutions. Open AI has found a counter example of initial conditions that don't have a smooth solution, i.e. they have disproven the existence problem.

36

u/moschles Sep 09 '26 edited Sep 09 '26

Correct. What had occurred over the course of several weeks (days?) is that Terry Tao said that there was nothing stopping the Euler trick from being extended all the way to Navier-Stokes. OpenAI simply had 10,000 agents fill in that extension and bridge the gap.

It is important to note here that the human mathematicians working in this space were already copiously utilizing AI-assisted technologies and AI proof systems -- including in particular NYU's Tristan Buckmaster.

Certain weird cases in fluid mechanics become solvable which probably would make engineers happy in a couple years.

u/srpulga Sep 08 '26

This is not what happened. No analytical solution has been found to the equations. The solution found is for the millenium problem which is to either prove a smooth solution always exists, or to provide a counter example disproving it. Open AI has provided the counter example: there are initial smooth conditions that can be proven to not have smooth solutions.

This doesn't make any fluid dynamics problem more solvable.

No there is no practical advantages.

Navier stokes dont apply to real life liquids at scales which blowups can occur.

As real life liquids are made of atoms. This in a way, requires infinitely many infinitely small atoms, which does not exist.

This is purely for the sake of better understanding of numeric techniques.

2

u/moschles Sep 09 '26

People who work in physics and the theoretical side of mechanical engineering know this is huge. The question is to what extent these idealized mathematical models to fluids stop extending to the real world. It is -- of course -- physically impossible for a fluid to have an infinite velocity. Navier-Stokes is a question about whether under well-behaved conditions the equations will spit infinities at you. It turns out they do.

Ok it seems this is what happened. Tristan and Levent (anthropic employee) solved the Euler problem which makes it easy to solve the NS problem. Before Tristan and Levent publish their euler and NS work, rumors spread that Anthropic solved the problem.

OpenAI heard the rumors and got scared that they were beaten by anthropic, so they assembled a team and put their strongest model with most comoute and possibly training on the most recent deidentified user data. OpenAI model then came up with a solution and the solution costed 20-30 millions.

What really worries me is how much did their model depend on the users data. As we all know, LLMs are insane in compressing data. It's really possible that their model attempted many attempts and one attempt was inspired by Tristan's work which he used chatgpt.

u/KiddWantidd Sep 09 '26

yes, per my understanding this is reasonably accurate to say. and the "team" literally consisted of tens of thousands of such mathematicians. the amount of compute they've thrown at this is just ridiculous, especially considering that it seems likely that they had a "good lead" regarding "in which direction" to look.

u/moschles Sep 09 '26

You need to consider what LLMs were doing with math 4 years ago. Struggling with high school problems, really. The progress is astounding.

Isn’t it just brute force search and wouldn’t we expect LLMs to be good at that (if you are willing to simulate thousands of examples to test)?

Yep. They used 10 thousand simultaneous agents to brute-force it.

Isn’t this in line with the previous result we have seen?

It is. LLMs are really good at finding counter-examples.

What is so special with this one?

In previous results, we could imagine that the particular conjectures were being berry-picked because they admitted some rare structure that made them extra-easy tasks for LLMs .

That dismissal is violently wiped off the table. Navier-Stokes is a Millennium Prize conjecture.
