It seems like they threw it a decently large battery of open math problems and probably limited it to something like $200-500 per problem:

As a complete guess, it seems like they tested hundreds to thousands of problems with a relatively low per-problem budget

I believe we're seeing a new kind of mathematics that will require completely new formats for publication, a bit similar to those used in experimental sciences. AI-powered mathematics should be fully reproducible, so it's the authors' responsibility to disclose the exact model type, inference settings/seeds and the full prompt history leading to the result. Of course that would ideally require open weights models.

It's not just about requiring to disclose AI use. AI-powered mathematics is a completely valid discipline that doesn't need to be shy, but it should develop its own publication culture.

reply
I can see this being important if you only care about the results as evaluations of AI progress, but if what you care about is the math itself why should you care about the prompt or anything other than the proof?
reply
Understanding the process that led to the proof helps to understand how to do further work on top of it, which is the goal of most mathematical research. It's not as though mathematicians are going to go launch a startup operationalizing their knowledge of how densely hyperspheres may be packed.

Because the math isn't solely about the proof being correct. You don't need to take my word for it, here's one of the most famous living mathematicians' take on it: https://teorth.github.io/tao-web/slides/age-of-ai-icm-2026.p...
reply
I don’t see Tao suggesting what you have suggested there. Instead he suggests that humans responsibly disclose AI use, and that mathematicians develop a set of norms to deal with an overabundance of AI generated results. For example, he suggests that authors should be able to discuss their results in detail to demonstrate understanding before publication.
reply
I agree with your reading of the presentation and I mostly agree with the presentation - but I believe the recommendations should go a bit further than they do there.
reply
I can't help but wonder about the human motivation there though. For instance as it became increasingly clear that LLMs were capable (and becoming ever more capable) of competently solving meaningfully complex software development tasks, suddenly then there came to be a lot of talk of 'prompt engineering' as a skill. The chronology doesn't make a ton of sense unless you consider that the main motivation may have been simply looking for a way to keep software engineers in the loop.

Pure math is relatively outside my domain, so I find it difficult to grok the exact relevance of the various published discoveries beyond that they are not insignificant, and LLM competence is expanding quite steadily across the field. If this trend continues to the point of LLMs being able to competently expand pure math, it seems somewhat predictable to expect there to be a number of people aiming to find ways to try to keep human mathematicians in the loop.

I've no idea what I think about this one way or the other, beyond that it's certainly a phenomena and one that's going to drive motivated reasoning that may not be entirely sound.

reply
I think those concerned about ensuring a place for human mathematicians usually go in different directions than my suggestion, at least those I've seen so far. Like this post that was recently featured on HN: https://kirwinhampshire.substack.com/p/the-dark-night-of-mat...

My perspective is more like a FOSS philosophy for math. Even if a closed version has the same immediate effect, it's just better for everyone if everyone can look under the hood and tinker with it.

reply
> suddenly then there came to be a lot of talk of 'prompt engineering' as a skill.

I would've thought pretty much the exact opposite. "Prompt engineering" was somewhat important in 2023/2024 when the models were much weaker, it doesn't seem at all necessary anymore (unless just "clearly stating your requirements" counts as prompt engineering). Most of the discussion I've seen seems consistent with this?

reply
The reason it's a meme right now is because there were a lot of people taking it seriously even when it was completely obvious nonsense. And one can argue it always was. There was some good advice that was mostly self evident, like having the most relevant instructions near the end of your context, but there was never a time when a 'prompt engineer' would produce dramatically better output than a random guy just clearly stating what he wants.
reply
While you may want AI results to somehow "not count" if the methods weren't disclosed, that doesn't present these results from poisoning the well for others. Once a result (with verifiable proof object) is delivered, the problem is solved, regardless of whether methods were disclosed.

Methods are only really necessary for results at a meta level, about the design amd evaluation of AI math systems.

reply
why is reproduceability the thing?

shouldnt the paper be the math of the argument? the reproduction is reading the following the proof

reply
I think this is a bit optimistic compared to my view (wrt portability). There's a large stack of software that is involved in training and probably less so in inference. I'm not saying it's impossible but there are definitely different levels of reproducibility and the academic incentive structure doesn't really prioritize reproducibility in my experience. I'm sure it varies quite a bit, I'd be curious to know how those in this problem space are thinking about reproducibility and at what level.
reply
I know it sounds unrealistic and not aligned with academic incentive structures. But those are the exact structures that gave us a lot of headaches in the experimental sciences. I think it would be a good north star to aim for something that resembles how those are trying to address the reproducibility crisis. Better than to embrace the most black-box version of math that AI systems can produce (million-line proofs without context). Even if a reproducibility crisis is seemingly impossible (although agents so far have also been pretty good at finding compiler bugs).
reply
If the proofs are formally verified by a proof assistant (Agda, Roq, Lean, ⋯), I see no reason we would need to know how these came about. All the information needed is in the proof.
reply
Unfortunately, we seem to already have an example of an LLM producing a proof in a week known open problem (the Collatz conjecture) in which it looks like it was sneaking a flawed proof through bugs in the proof checker. https://infosec.exchange/@0xabad1dea/117002106099986943
reply
Exactly, this is an example of "Reward Hacking", that is too common in a lot of cases.

Another case I want to highlight is writing GPU kernels as illustrated by the following example: Say I want to generate random number with Normal (0, 1) distribution. Often times the AI written kernel will just generate the number 0. The tests often fail to catch these errors.

reply
What if the AI has discovered some new function F that allows it to generate (insanely large) proofs for a ton of theorems in a ton of different fields. Wouldn't you like to know more about this `F`? That seems to be the real innovation in this case. How much about it could be gleaned from the individual proofs themselves? What if this `F` is actually simple enough to be digestible by humans?
reply
Yeah I remember reading about something along the lines of Mathematics is now about the scaffolding around you find the problems/solutions not just the problems and solutions. For teaching purposes. This was before this ai craze
reply
I don't think you want to bring cost into this argument.

Even if the cost was $1 mil for these 10 problems, that's maybe 10-20 math researchers for a year.

Do you really think that if you paid that to humans, they will deliver the same results?

reply
It is comical at this point. Some people just can not stand the thought of AI actually delivering and are trying to find whatever ways to discredit it.
reply
This isn't really about delivering - it's more about helping to understand the shape of problems that AI can solve right now. If they took 1000 problems and threw the model at it and it solved these ten, is there something we learn about these ten problems and the kinds of things that current AI is good at? That's very different from picking ten problems _at random_ and solving all of them successfully, which would suggest a much less bumpy capability surface. It's interesting and it would be good science to release it.
reply
That's totally disjointed from anything in this thread. The main accusation is that openai is cherrypicking math problems and we should be against these results. As if a mathematical proof stops being provably correct because it was cherry picked

And frankly these "concerns" ignore reality. In any research phd course you're actively told to bite off something small and likely to be provable so that you can prove it (and publish it). Openai telling its computer to do that is no different that your phd advisor telling you that.

reply
It's disjointed?

The post that started this sub-thread asked:

> 1. How many total problems were given to the model, and what percent were left unsolved at what cost before giving up? 2. How many attempts did you give the model at solving these problems? 3. How expensive was the harness, e.g. did the model have access to a job cluster?

I think it's an extremely relevant question to ask, because it helps us better understand the current state of AI being able to handle math, for exactly the reasons I outlined. I was arguing against the idea this is just a reactionary anti-AI kind of question to ask. It's not! You can be very impressed by what AI is capable of in math (I am) and still think those are really interesting things for OpenAI to disclose (I do).

OpenAI specifically called out a $2000 per problem average, which implies something that's probably not true ("if you throw $2k at us we'll solve an open problem for you"). It would be cool to know what the actual number is.

reply
It just feels silly to haggle about the price here. It doesn't even matter because it's going to drop by an OOM quickly.

If these 10 problems were solved by humans, it would be pretty impressive, even if it took a large number of researchers! Yet when AI does it, HN commenters suddenly feel the urge to play accountant.

reply
> In any research phd course you're actively told to bite off something small and likely to be provable so that you can prove it (and publish it).

But that's the start of math research, not the end.

The point is to get practice and experience doing research.

Did ChatGPT learn anything from these proofs, that it can build on?

Part of what's annoying people is that ChatGPT is churning though problems that are meant to be motivating. They are problems that aren't worth the effort of human professionals (usually because they are incredibly computation-hevy, so better suited for a computer than a human), so they are good for students to work on.

reply
It's not about discrediting AI. We know LLM is a commodity technology like electricity at this point. If somebody in 1900 claimed they had a setup at home where they feed in electricity and cool air comes out the other end (meaning they invented AC), obviously people would want to know what the setup is, so everybody can have AC.
reply
Entirely comical too that some people can not stand the thought of people poking very big comulent holes in the claims of AI delivering what it claims to deliver. As if having skepticism is some how a way to discredit a person.
reply
Sure, but I don't really understand what the argument is to _not_ be transparent about methodology, since if the models are so powerful, then doing so would easily support the claims and put these concerns to rest. People are right to be skeptical given what is being implied and the orientation of the narrative

I know it's more exciting to say "AI disproved a longstanding conjecture" vs to say "it did so AND it took several PhD specialists in the field this many attempts to even produce a prompt that got the model spitting out something useful under some configurations, and many iterations to optimize the configurations, and the prompt itself, and many trials with that configuration to solve the problem. All told we spent more than a typical math academic can hope make in their career."

By not being transparent, they invite skepticism and cynical takes, like maybe it's just that tempered and qualified claims are an existential threat to companies that are fully subsidized by the hype train?

I don't know. Either way, it seems like it would be easy to address these, so why should they not do it?

To be clear, even if that tempered version is close to reality, it doesn't make the models not useful! It just forces a certain calibration of expectations

I say this btw as someone who uses these things extensively, including to disprove an old conjecture my advisor and I were stuck on recently. I know they are powerful and that everything is different now because of them. Let's be sober when discussing them though

reply
You need to bring both cost and benefit into the argument, and it's not necessarily an obvious win for either side. There are a few complicating factors here.

The cost of running a model is not only $/token, but the salaries of the people managing/orchestrating the models, deciding what theorems to try, etc. Once we factor that in, how much are we really paying per theorem?

The other factor is the subjective component of the value of a theorem. Not all theorems are created equal, and the only way to really measure the value is to ask professional mathematicians for their opinion, or publish the results and look at citations over months/years.

Once we have both of these nailed down, then we can start to do the cost/benefit analysis. To be fair, we should actually compare three groups: human experts, hybrid agent/human expert teams, and fully autonomous agents.

It's a marketing post from a huge company. Only the naive would view it uncritically without assuming it's been written carefully to present the results in the best possible light while skirting the boundaries of outright lying.

reply
The results speak for themselves.

Imagine 2 years from now: "yes, GPT solved the Riemann Hypothesis, but cmon, it's just a marketing stunt to hype their stuff, it was probably Terence Tao doing the work but he's so obsessed with hyping AI that he doesn't want to take credit"

reply
Nobody is claiming the results are false.

We're saying look critically at the claims for how it was done, that it only cost $2000, etc. it would be extremely easy to run 100 sessions that failed, each costing ~$2000, and then just publishing an article about the one that succeeded, for example.

This goes double since it's an internal secret model (Astra) so nobody else can verify the results.

reply
Would this be your reaction if OpenAI also solved millennium problems? The point we are trying to make is that the significance of this news is much larger than the skepticism you are providing.
reply
If OpenAI resolved the Riemann hypothesis by finding a nontrivial zero at 0.50000003 + 3531696584231.17843174i, that would be very cool and probably very impactful. But it might not necessarily demonstrate model capabilities beyond those which have already been demonstrated, especially if the session that found it was one of a thousand launched to explore different areas of the problem space.

More generally, do you expect that there's some capability threshold where people will no longer study or analyze AI model outputs, and instead just sit there slack jawed saying "so cool!" every time OpenAI announces novel ones? I don't really understand why that would be or why someone would want that. If you're interested in the pure experience of a complex machine outputting satisfying results, I'd recommend getting into sports cars.

reply
Ok are you one of those people whose first reaction to such a news is “this is just marketing for OpenAI and we need transparency”? In that case you are just interested in culture wars and not results.
reply
It would be my reaction if we're discussing a blog post from OpenAI, yes. I would be looking at it extremely critically, wondering what they're misrepresenting to make it look cheaper, easier, and why they're trying to make it look like only their model could possibly do this.

Look at their recent claims about their model "escaping" - there was literally a Guardian article calling them out for being hyperbolic! Again, it wasn't that they lied, their marketing department is too savvy for that. They just present it in way that's, well, marketing.

As for the actual result, I'll look for secondary posts by actual mathematicians and draw my conclusions there, not from this marketing blog post about results from a secret model.

reply
Hmm. But this level of skepticism looks performative and seems to serve as a signalling thing rather than a functional thing. You do you though. If OpenAI solves the millenial problems, my skepticism will only be restricted to the correctness of proof. Not that it was "marketing" haha

Company X does not make money from proving theorems but does make money from selling you a service which supposedly proves theorems. Company X then proves some theorems and explicitly calls out they were very cheap to prove using its service.

Brother I already conceded that money is somewhat important but it is missing forest for the trees.

If OpenAI solved Reimanns hypothesis and the first comment is says something about lack of transparency and marketing, i would say it’s ignorant.

reply
To "solve it" would require either a single counter example disproving the claim, or a proof that the conjecture about the Riemann zeta function is true.

If OpenAI claimed the conjecture to be true but provided no details about the proof then the first comment should absolutely be about lack of transparency.

reply
> no details about the proof

do you really imagine a scenario where OpenAI would claim to solve it and not give details about the proof? how is this even possible? why would anyone believe them?

reply
> looks performative

That's one of those phrases you can use to dismiss opposing viewpoints without actually engaging with them.

reply
No, this is valid criticism. Oai gives the impression anybody could get similar results at a similar price, but that’s very likely not true. This is marketing first, then mathematics.
reply
> therefore the $2000 number could be completely misleading, similar to P-value hacking by not disclosing the total experimental setup.

I don't think that comparison to p-hacking is fair. I mean not reporting price of all run is nothing like committing scientific fraud and fake results.

reply
Also, have there been examples of researchers not affiliated with OpenAI (or another LLM creator), who have done something similar?

Another question I have is whether or not OpenAI 'simply' hired capable combinatorics researchers to work on problems, and they have, and the use of the model is incidental / secondary to their work.

A couple small ones that I've seen (example here [0]), but not anything of the magnitude that OpenAI and Anthropic have put out. Likely just related to token limits.

> Another question I have is whether or not OpenAI 'simply' hired capable combinatorics researchers to work on problems, and they have, and the use of the model is incidental / secondary to their work.

I think their output has reached a level that precludes this possibility, but I of course don't have any hard proof.
