AI Progress Explained: From Math Olympiads to Navier-Stokes — Transcript
Full transcript
- 0:00AI's progress in mathematics has been
- 0:02remarkably fast. Not too long ago,
- 0:05frontier models struggled with grade
- 0:06school math. Now, they're contributing
- 0:09solutions to problems that have resisted
- 0:11mathematicians for decades, including
- 0:13most recently the Navier-Stokes
- 0:15equations. But, as AI moves from tests
- 0:18we already know the answers to to more
- 0:20open-ended research challenges, it gets
- 0:22harder to understand what these systems
- 0:24are truly capable of and what their
- 0:26progress tells us about where AI is
- 0:28headed. My guest, Greg Burnham, leads
- 0:30capabilities research at Epoch AI, where
- 0:33he and his team are developing new ways
- 0:35to track AI's rapidly evolving strengths
- 0:37and limitations. Here's Greg on why
- 0:40measuring and understanding AI's
- 0:42capabilities matter so much right now.
- 0:44>> AI capabilities writ large have gotten
- 0:48to such a point where
- 0:50what they're good at and bad at is
- 0:52starting to have real impact on the
- 0:54world, like on things we care about for
- 0:56other reasons. We're past the academic
- 0:59exam phase of understanding AI
- 1:02capabilities. And for that, we need
- 1:04high-quality benchmarking, high-quality
- 1:05evaluations. And one of my big questions
- 1:08here is just can AI come up with new
- 1:10ideas? If AI systems get sort of
- 1:12superhuman at this, that's a a big deal
- 1:15for for the world, both in terms of
- 1:17economic and scientific progress, but
- 1:19also in terms of becomes harder to
- 1:22predict what AI systems are capable of.
- 1:25We use math as a testbed for this.
- 1:28>> I'm Sam Charrington, and this is the
- 1:30Foomool AI podcast. For over a decade,
- 1:32I've been exploring the ideas and
- 1:34innovations shaping the future of AI
- 1:36through conversations like [music] this
- 1:37one that help you understand what's
- 1:40real, what's next, and what matters.
- 1:42Let's jump in.
- 1:52Let's talk a little bit about AI
- 1:53capabilities research broadly, how you
- 1:56pursue that research, and why you think
- 1:57it's important.
- 1:58>> We're getting to a point in the in the
- 2:01trajectory of AI overall where
- 2:05AI capabilities can have a real impact
- 2:08on the world. So,
- 2:11maybe the transition could be
- 2:12characterized as school to work.
- 2:17In maybe even up through Yeah, up
- 2:20through 2025 most ways that we tested
- 2:24what AI could do looked more like human
- 2:27exams, like that you might give to, you
- 2:30know, to kids or to maybe advanced
- 2:33graduate students.
- 2:34>> I was going to say.
- 2:36>> Right, right. The The kid exams. It It
- 2:38is remarkable.
- 2:39>> the
- 2:40medical exams.
- 2:42>> And these like AI was perfectly good at
- 2:44these already end of 2024 beginning of
- 2:462025. So, we really saw saw this
- 2:49transition happening over time to to be
- 2:52clear. But, this is This is certainly
- 2:55the year where AI capabilities are
- 2:57impacting
- 3:01work activities that humans were engaged
- 3:04in anyway for, you know, for their own
- 3:07purposes. And so,
- 3:09as these capabilities grow, it's just
- 3:12important for us to keep tabs on them.
- 3:15They grow very rapidly in some
- 3:17qualitative sense. We see no No
- 3:19measurement we have shows any slowdown
- 3:23in what and how AI is getting better and
- 3:26better at any tasks that we're able to
- 3:28measure. And so, we
- 3:31think that just understanding the impact
- 3:33AI will have on the world it's important
- 3:36to know what it can do, what it can't
- 3:37do, and keep it and keep tabs on how
- 3:39that how that trajectory is going.
- 3:41>> I want to push back on one thing you
- 3:43said
- 3:44in terms of we're not seeing any
- 3:47slowdowns
- 3:48that can be looked at broadly like in
- 3:52terms of maybe the number of, you know,
- 3:54benchmark data points that we're looking
- 3:56at. You know, certainly we're seeing
- 3:58this broad performance.
- 4:00But, is it also true that like on a
- 4:03particular
- 4:05I feel like on a particular benchmark we
- 4:07get it like the, you know, for for
- 4:09expected reasons when we went from, you
- 4:12know, GPT-2 to GPT-3 like we're taking
- 4:15these huge steps up these benchmarks and
- 4:18now like there's just
- 4:19a lot less room left and we're making
- 4:21more incremental progress. Do you see
- 4:24that as a a slowdown in AI performance
- 4:26or is would you characterize it
- 4:28differently?
- 4:29>> I would say, well, I'd say there's two
- 4:30issues here. One is on the benchmarks we
- 4:33have, what does performance look like?
- 4:36Two is
- 4:38are there things our benchmarks don't
- 4:40measure that maybe there has been less
- 4:43or could even be negative uh
- 4:46improvement on but because and is there
- 4:48some reason why
- 4:51it's the things that are hard to measure
- 4:53where there's been the least progress.
- 4:54But on the first point, cuz this is a
- 4:56very this is a much more cut-and-dried
- 4:58statistical point. We absolutely see
- 5:01continued progress on benchmarks like
- 5:04a benchmark that was challenging for
- 5:06GPT-3,
- 5:08uh
- 5:08you know, many years whatever, six years
- 5:10ago, uh is now completely, you know,
- 5:14solved, uh aced by GPT-4. Benchmarks
- 5:18challenging for GPT-4, same for GPT-5.
- 5:21Now we've got GPT-6. So, we do some
- 5:23statistical work to try to aggregate
- 5:26benchmarks over time because the
- 5:29benchmarks that people used to track
- 5:32progress years ago, now every AI model
- 5:36off the shelf that you've heard of that
- 5:37you might use is too good at them. Uh
- 5:40so, people make new benchmarks and then
- 5:41you have to sort of do this like
- 5:42stitching of like, okay, well, a model
- 5:45that was pretty darn good at this
- 5:47benchmark, was not so good at this next
- 5:49one. And you can use like a you can
- 5:51stitch those together and get this sort
- 5:53of composite score. We call that we we
- 5:55have a methodology for doing this we
- 5:57call the Epoch Capabilities Index. And
- 6:00that's a unified way of tracking
- 6:02benchmarks over time and and we really
- 6:04do see this thing continuing to go up uh
- 6:07you know, pretty smoothly, linearly. And
- 6:10and that march of progress is uh is is
- 6:13steady. That's an important part. Uh and
- 6:15that that's truly a if
- 6:17>> [clears throat]
- 6:18>> um
- 6:18we we have we've made more benchmarks
- 6:21and AI systems that are harder, that
- 6:23models start off at zero and then within
- 6:26a year or two years they're at 100% and
- 6:29we have to make a new benchmark to keep
- 6:30up. Uh and that's that's really been the
- 6:32story of the last uh certainly the last
- 6:35three years I'll I'll I'll say with
- 6:36confidence there.
- 6:38>> It seems like that like normalizing
- 6:41across different benchmarks to
- 6:44produce a result that is coherent. That
- 6:49sounds like a very challenging problem.
- 6:51Like you
- 6:52you you describe the result as like you
- 6:56know, kind of continued linear
- 6:57improvement and
- 6:59I imagine if
- 7:00that's like a constraint, you can kind
- 7:03of map backwards to you know,
- 7:06uh to factors that will show you that
- 7:09continuous linear improvement, but you
- 7:11know, starting from
- 7:13you know, set of disparate benchmarks
- 7:15that have their own kind of you know,
- 7:17ranges and challenges and you know,
- 7:19where AI you know, and where AI sits in
- 7:22them and and kind of mapping this across
- 7:24different generations of AI and
- 7:27coming up with a you know, something
- 7:29that makes sense
- 7:31you know, objectively at the end and
- 7:32then having that thing show continued
- 7:35linear progress, that sounds like
- 7:38um
- 7:41you know, almost like too to be true and
- 7:44like suspicious that it is true.
- 7:46>> I I
- 7:46Yeah, I I agree. So so let let me go
- 7:49into that a little cuz I think it's a
- 7:51it's a killer point to understand. And
- 7:53it is surprising. So I think you're
- 7:55you're very right to be surprised.
- 7:57In fact, if you look at AI benchmarks,
- 8:01they are all correlated with each other.
- 8:03Even if the benchmark the scores across
- 8:06models are correlated with each other,
- 8:08even if the benchmarks are in nominally
- 8:10different domains. So maybe you don't
- 8:14expect you don't find it so surprising
- 8:16if it's like I've got one benchmark
- 8:18that's, you know, graduate chemistry
- 8:21questions and I've got another one that
- 8:23is coding puzzles. And the models that
- 8:26are good on chemistry are also good on
- 8:28software engineering.
- 8:29>> Well, they should be correlated largely
- 8:32by the the models themselves. Like as
- 8:34the models get better, they're going to
- 8:35get better across these, you know,
- 8:37disparate benchmarks.
- 8:38>> But but this
- 8:39Exactly, but that's that's the
- 8:41surprising point. So all that you need
- 8:43to be true to see this linear trend over
- 8:45time is basically every time, you know,
- 8:49Opus 4.5, Opus 4.6, 4.7, GPT 5.2, 5.4,
- 8:54every time these come out, if they get
- 8:56better on all benchmarks at once, then
- 8:59you're going to see this linear trend
- 9:00this this big over time linear trend.
- 9:03Like that's it's two sides of the same
- 9:05coin statistically. Why does this
- 9:07happen? Like this is a huge question.
- 9:09Like you're right to find that
- 9:11suspicious. And I would say there are
- 9:13two explanations that we see. And it's
- 9:17an important question which of these
- 9:19explanations is more true. And of course
- 9:21the truth is some mix, but but let me
- 9:23let me give the the two explanations.
- 9:26One is
- 9:28the AI companies are making darn sure
- 9:32that their model gets better at all of
- 9:34these benchmarks
- 9:36with each new generation of model. And
- 9:39the main mechanism you might imagine
- 9:40them doing that, if they're like looking
- 9:42around, okay, people care about
- 9:44chemistry, people care about software,
- 9:45people care about operating, but you
- 9:48know, answering my email. Like they they
- 9:50would collect training data one form or
- 9:53another that would help the model learn
- 9:55how to do these how to do these tasks.
- 9:57And that's something of a
- 10:01um that's something of a you know, very
- 10:03manual human in the loop process of just
- 10:05saying, hey, we're doing product
- 10:06development. Like they want this
- 10:07feature, they want that feature. Our
- 10:09users want all these features. And the
- 10:10way you do that in machine learning is
- 10:12you collect training data and throw it
- 10:13in.
- 10:14I'm oversimplifying, but that that's
- 10:16that. Um
- 10:17it's sort of like a shallow way to make
- 10:19it happen. That so call that shallow.
- 10:21The other one is deep. The deep way to
- 10:23make it happen is if the model general
- 10:26is if the AI system can generalize very
- 10:28very well. So yeah, you never trained it
- 10:31on chemistry, but you trained it a lot
- 10:34on math and software engineering, and it
- 10:37just got super smart, and with a modicum
- 10:40of chemistry basics, it was able to
- 10:43derive the rest from first principles so
- 10:45it's sort of thing. This is like a deep
- 10:47form of generalization. Both of these
- 10:49happened to some extent. Like kind of
- 10:51the revolution with GPT even GPT-3
- 10:55around that era, this is like quite a
- 10:56while ago, was oh, if you train it to
- 10:58like predict the next word, then it
- 11:01actually gets better at a wide wide
- 11:03range of language oriented tasks that
- 11:05people had been trying to handle
- 11:07individually, suddenly it just got got
- 11:09good at everything. And that wasn't
- 11:11because anyone was like, oh, let's have
- 11:13data specifically around
- 11:16sentiment analysis or or syntactic
- 11:20structural analysis. Like it wasn't
- 11:21anything like that. It was just give it
- 11:23give it this very general thing. But now
- 11:25we're on to this world where you have to
- 11:27like train it specific Right now,
- 11:28there's a huge industry of collecting
- 11:30all this rich training data, and it's
- 11:32really unclear how much generalization
- 11:34you're getting from, you know, in this
- 11:36deep way.
- 11:38Uh and
- 11:39and if and anyway, that's that's sort of
- 11:41a big question cuz that deep
- 11:43generalization means you could really
- 11:44see if that happened in a in a rich way
- 11:47where you just didn't have to even be
- 11:48trained on something at all to gain
- 11:50capability in that area, then you might
- 11:53have a or like radically superhuman AI
- 11:55that would be um pretty hard to to
- 11:58understand like to to bound its
- 12:00capabilities.
- 12:02>> It's still a little counterintuitive
- 12:03that this would be
- 12:05that this would be linear and maybe
- 12:08yeah, maybe part of the question is like
- 12:10are we talking about
- 12:14you know, linear across generations of
- 12:18of of model releases or linear within
- 12:21some regime like segment, you know,
- 12:23segmentally linear or
- 12:25>> The The thing I can say is
- 12:27we have like a statistical methodol-
- 12:29from a benchmark score. Like what are we
- 12:31talking about here? Our unit here is a
- 12:33score from 0 to 100% and typically the
- 12:37way these scores go just historically
- 12:39empirically is like they follow like an
- 12:41S curve. Like like they start out sort
- 12:43of bad, then they get better, they get
- 12:45better pretty rapidly, and then you can
- 12:47only get up to 100%, so then they sort
- 12:49of level off, takes them a while to get
- 12:50that last, you know, little chunk, and
- 12:53then they're at 100%. So you've you've
- 12:55got these like sigmoids. Uh is is what
- 12:58that S curve is called. We just got a
- 12:59statistical methodology for stitching
- 13:02sigmoids together, and what comes out is
- 13:05a linear function, and this looks like
- 13:07like this is a artifact of the
- 13:08statistics to be clear, but this sure
- 13:11enough looks very regular in its own
- 13:14statistical analysis terms over across
- 13:17generations of of models. Like
- 13:19absolutely, like it's been a
- 13:21if anything it accelerated a little with
- 13:23the development of so-called um
- 13:25reasoning models around late 2024 where
- 13:28the model started to get good at math
- 13:30and and software engineering and things
- 13:33that require lots of logical reasoning.
- 13:35Uh maybe like with a higher linear
- 13:37slope, but uh but this is just like a
- 13:39that's a statistical artifact. You now
- 13:40have to ask, "Okay, well, if your score
- 13:42is like one model score is 150 and the
- 13:45next model score is 152, like what do
- 13:48those two points mean on your benchmark
- 13:51aggregate index?"
- 13:53Now
- 13:54>> part of part of what I'm what I'm asking
- 13:57myself as I hear this
- 13:59described as linear is does it say that
- 14:02in spite of the model the frontier lab
- 14:05vendor claims that, you know, Fable is
- 14:10like dramatically better than Opus or
- 14:12that GPT-6 is like the step function uh
- 14:16you know, improvement over GPT-5.6,
- 14:19you know, linear implies to me that that
- 14:22it's kind of incremental and there's
- 14:23really been no step functions.
- 14:26>> This is um this is a really great
- 14:28question and yeah, the we believe this
- 14:30is one of the big uses of this
- 14:33statsy tool we've got is you can try to
- 14:36find,
- 14:37you know,
- 14:38trend breaks and you can try to find
- 14:40accelerations.
- 14:42Uh and we mostly don't see that. Yeah,
- 14:44like one way to put it that is
- 14:47everything just about is on trend.
- 14:49Fable,
- 14:51uh Astra, whatever is on trend, but the
- 14:54trend is crazy. Like
- 14:56>> [laughter]
- 14:56>> you got to you got to hold both of these
- 14:58together.
- 15:01>> Right. Right. Right. Right. Right.
- 15:03>> This is like this is sort of the zoomed
- 15:04out view Epoch takes with with
- 15:06everything is a lot of this we think the
- 15:09engine of AI progress is heavily
- 15:11mediated by raw inputs like GPUs, the
- 15:16training compute, like training data.
- 15:19Maybe those are the big ones. And then
- 15:20there's this like factor of the labs
- 15:22come up with algorithmic like
- 15:23innovations, like research
- 15:25breakthroughs. But we really think like
- 15:27a lot of it is coming from the scale up
- 15:29in the in the compute and the scale up
- 15:31in the training data.
- 15:32>> So until you see the data and the GP the
- 15:35data and compute supply chain like ramp
- 15:39uh significantly or discontinuously
- 15:42uh to be more precise, you're not going
- 15:44to see
- 15:45you're not likely to see discontinuities
- 15:48on the model side.
- 15:49>> I think that's I think that's right. A
- 15:51big thing we're keeping our eye on to be
- 15:53clear is
- 15:55are there the are AI abilities emerging
- 15:58that could cause a discontinuity on the
- 16:00model side? So this is why people talk
- 16:03about recursive self-improvement or
- 16:05sometimes they call this a software-only
- 16:08intelligence explosion. Uh and the point
- 16:10of these concepts is well, sure right
- 16:14now there's a slow it comparatively slow
- 16:17process for building more micro building
- 16:20more GPUs and collecting more human
- 16:22training data and whatnot. But if an AI
- 16:24system got really good on the
- 16:27algorithmic innovation side, could it do
- 16:30more with less or or do more with the
- 16:32with a fixed uh
- 16:34compute budget? And that could change
- 16:37the dynamics here. So the feedback loop
- 16:39wouldn't might no longer run through the
- 16:41physical world. We don't really it's not
- 16:43clear we see evidence of this yet. I'd
- 16:45say on balance we don't really see
- 16:47evidence of this yet. But it's the sort
- 16:50of thing that has spooked the people
- 16:52inside the labs that the AI companies I
- 16:55mean saying like gosh, this could be
- 16:57right around the corner. That's like a
- 16:58bit of the fear. And if that happens,
- 17:00then the pace we're used to
- 17:02we might get that discontinuity.
- 17:05>> Have you developed a particular
- 17:06benchmark to identify and track this or
- 17:10is it more
- 17:12the way you look at the benchmarks that
- 17:15we've been talking about, the
- 17:16statistical model that we've been
- 17:17talking about for an indication
- 17:20that, you know, there's some kind of,
- 17:23you know, exponential
- 17:25uh in the curve and and that's, you
- 17:27know, probably one of the likely causes,
- 17:29you know, for that kind of
- 17:30exponentiality discontinuity.
- 17:32>> All of the above. Uh we we want as many
- 17:35as many tools in our arsenal as as we
- 17:37can for this. So that to this statsy
- 17:40like acceleration detector is definitely
- 17:44a good uh is definitely a good tool. But
- 17:46we also sort of get, you know, down in
- 17:48the weeds with some of our specific
- 17:51evaluations and benchmarks saying, I'll
- 17:53give you an example.
- 17:55Here, this is some forthcoming work we
- 17:56have uh that that I'm happy to to
- 17:58preview.
- 18:00We take a recent AI research
- 18:03breakthrough or innovation,
- 18:07uh
- 18:07from humans, and we take AI systems, we
- 18:12don't connect them to the internet, and
- 18:13we choose AI systems that uh were
- 18:16developed and released just before this
- 18:18recent cute whatever the recent human
- 18:20innovation is, and we basically say,
- 18:23look, here's the metric that that
- 18:24innovation, the number that it makes go
- 18:26up, it improves this sort of efficiency,
- 18:28what whatever, some some metric. And we
- 18:31say, AI system, your goal is to improve
- 18:32this metric as much as you can.
- 18:34Uh but we don't tell it the innovation.
- 18:37And so we see, is it capable of
- 18:39replicating that human innovation that
- 18:42was highly relevant for AI, you know,
- 18:45research and development.
- 18:47And so far we don't see them able to do
- 18:49this. There's this nebulous idea called
- 18:52research taste, which is like, where's
- 18:55the good idea? Like, what what
- 18:56experiment should I do next? Where
- 18:58should I go hunting for uh big
- 19:00improvements more than the mundane
- 19:03improvements of just more compute, more
- 19:05data? Like, where should I look for for
- 19:07a breakthrough? And AI systems don't
- 19:09seem great at doing this in um at least
- 19:12in an AI
- 19:14R&D context. Uh, but but they're like
- 19:17getting a lot better at a lot of things
- 19:19that are adjacent to this uh, to this
- 19:21area. So, we we really do think this is
- 19:23an important, sometimes I almost call it
- 19:25a tripwire, that where you know, the the
- 19:27future is foggy uh, is some foggy
- 19:29landscape. We want to put a tripwire out
- 19:31there so that if AI ever does cross some
- 19:33threshold where it's able to do rapid
- 19:36improvements in AI algorithms
- 19:39themselves, then uh, we we want that
- 19:41tripwire to sound so we go, "Okay, gosh,
- 19:43watch out. Like maybe maybe something
- 19:45uh, maybe we're about to see a big
- 19:47improvement a big big um, you know,
- 19:49uptick in AI AI capabilities."
- 19:51>> And how does this relate to
- 19:54AI's performance on some of the math
- 19:57challenges? You know, certainly
- 19:59Navier-Stokes has been
- 20:01uh,
- 20:01in the news quite a bit recently. Prior
- 20:04to that, there were some Erdos results
- 20:06uh, and others like
- 20:08how do you think about the role that
- 20:10those math challenges play in this
- 20:12broader
- 20:14view of trying to understand AI's
- 20:16trajectory?
- 20:18>> Yeah, the very good question. Uh,
- 20:20if if I may, I would
- 20:23go rewind history just a just a bit here
- 20:26to um, say some of the say the
- 20:28trajectory we've been on cuz once you
- 20:31you step back, it's um, it's it's wild.
- 20:34Uh,
- 20:35so
- 20:36up until
- 20:40Yeah, up until
- 20:42fall of 2024, so we're talking 2 years
- 20:44ago.
- 20:45Uh,
- 20:46grade school math was still a challenge
- 20:49for these LLM based AI systems, the the
- 20:52kind of AI we're talking about here.
- 20:55And all and the benchmark there was
- 20:56literally a benchmark of 8,000,
- 20:59you know, word problems.
- 21:02So, and so yeah, so has so many apples
- 21:04that sell for this and
- 21:05>> GSM8K.
- 21:06>> GSM8K, that's the one. And
- 21:10GPT-4, which is 2023, had like done
- 21:12pretty well on this. So, people started
- 21:14looking at
- 21:15like adding into the mix a benchmark
- 21:17just called math, like four capital
- 21:19letters,
- 21:20that
- 21:21started pulling from some high school
- 21:23math competitions. And there was like
- 21:25slow progress on this, but but not a
- 21:27lot. And then at the end of fall of
- 21:292024, OpenAI comes out with the 01
- 21:32preview model, full 01 by the end of
- 21:352024. And this showed a huge spike in in
- 21:38math competition capabilities, but we're
- 21:40still just talking like medium hard high
- 21:43school math competitions. Like
- 21:44something, you know, thousands of math
- 21:46nerd nerdy math 16-year-olds were were
- 21:49into
- 21:50across the across the US. And
- 21:54and this became, you know, the new the
- 21:56new territory. My my company, Epoch,
- 21:58around that time released a benchmark
- 22:00called frontier math. At the time,
- 22:03that's all we called it. We now call it
- 22:05tiers 1 through 4 to distinguish from
- 22:08later versions, I'll get to in a bit.
- 22:10But the original frontier math consisted
- 22:13of problems that I would say go from
- 22:15advanced undergraduate to advanced grad
- 22:18student. So, sort of early career
- 22:21research warm-ups almost. These are
- 22:23problems that are no longer thousands of
- 22:28thousands of high schoolers would tackle
- 22:31them. These required deep background
- 22:32knowledge in in various areas that that,
- 22:36you know, niche areas. Like we're
- 22:38talking a a problem from you know,
- 22:41elliptic curves that you'd give to a
- 22:45grad student like shortly before they're
- 22:47going to embark on their novel thesis
- 22:49research. Just to get them familiar with
- 22:50the details of the of the niche that
- 22:52they're going to be trying to work in
- 22:54and make an original contribution to.
- 22:56Over the same period, we also saw high
- 22:58like so over 2025, we also saw high
- 23:00school math contests get completely
- 23:03aced. We got the gold medal on the
- 23:05International Math Olympiad by the um
- 23:09even by the beginning of 2026, we saw
- 23:12most of these frontier math problems
- 23:14solved, though not all of them had had
- 23:16in fact been solved by an AI system uh
- 23:19at that point. And so just like
- 23:22even just here, this is a very rapid
- 23:24trajectory from uh over the course of
- 23:27just a little over a year going from you
- 23:30know, like
- 23:32hobbyist high schooler to graduate
- 23:35student. Like very competent kind of
- 23:38you know,
- 23:39up there graduate student in terms of
- 23:41the problems they could solve. Really
- 23:43rapid AI progress.
- 23:46At the same time, we started to see
- 23:48people test AI systems on
- 23:51unsolved math problems. Uh problem like
- 23:54the the frontier was no longer something
- 23:57This is what I mean with We've gone from
- 23:58exam to on the job uh where it wasn't
- 24:03like here's your qualifying exam as a
- 24:05grad student anymore. It became more
- 24:06interesting to say, "Well, here's a
- 24:08small problem that maybe a mathematician
- 24:10a professional thought about for an
- 24:12hour, didn't solve. AI systems, can you
- 24:14do it?"
- 24:15And at that level, we started This was
- 24:19all just this year, like 2026. At the
- 24:21beginning of the year, there were like
- 24:22starting to be claims of oh, maybe
- 24:24here's a problem that was posed by a
- 24:26famous mathematician. This is maybe the
- 24:28Erdős problems. The This is just for
- 24:30background, there's this very prolific
- 24:32mathematician Paul Erdős
- 24:34who proposed over the course of his life
- 24:36maybe like well over a thousand, maybe a
- 24:39couple thousand problems. Other people
- 24:40still like haven't fully cataloged all
- 24:42the questions he asked. Some of those
- 24:44became central to to whole fields of
- 24:46math. Some of them were, you know, no
- 24:48one really paid much attention to,
- 24:50including Erdős himself. And AI started
- 24:52to notch a few solutions to some of the
- 24:56easier ones of those.
- 24:59Fast forward to May
- 25:01of this year and and an internal model,
- 25:04probably something like the Astra model
- 25:07that we now have publicly available, was
- 25:10able to solve a big one of those. This
- 25:12was sort of a a historic moment. May the
- 25:14so-called unit distance problem
- 25:17from
- 25:18which was a problem about how many
- 25:20points you can fit in the plane that are
- 25:23just one unit distance of one apart from
- 25:25each other. Sort of like very cool that
- 25:27you could frame it such a simple
- 25:28problem, but there hadn't been progress
- 25:30much progress on this problem despite a
- 25:32lot of attempts
- 25:34since Erdos had had posed it, you know,
- 25:36decades and decades before. And it was a
- 25:38serious problem. It wasn't one of these
- 25:39no one had thought about it. It was
- 25:41definitely had received a lot of
- 25:42attention and an AI system solved it and
- 25:44it was really this this was like a
- 25:47aha moment of oh my goodness like AI can
- 25:49solve problems that humans have cared
- 25:52about just independently.
- 25:55And we've seen a lot more of that since
- 25:57and the the you know, with the sort of
- 25:59the the recent wow moment being the
- 26:02solution of the Millennium Prize
- 26:04problem. This was, you know, the
- 26:05Navier-Stokes problem. This was a
- 26:07collection of this these Millennium
- 26:09Prize problems, a collection of seven
- 26:11problems that
- 26:13mathematicians sort of or at least one
- 26:15math institute set as like good goals
- 26:17for the new century. Like they were they
- 26:19were they're much older than
- 26:21the year 2000, but but they were sort of
- 26:23canonized in the year 2000 as hey like
- 26:26these are worthy targets of entire
- 26:28subfields of mathematics and it would be
- 26:30a big deal. And so one of them was
- 26:32solved. So it's been a hell of a hell of
- 26:34a ride.
- 26:35>> The historical context is super
- 26:37interesting. It you know, we're all
- 26:39living through this trajectory, but to
- 26:42step back and see, you know, how much
- 26:44has happened in the past couple of years
- 26:46is pretty pretty nuts.
- 26:49>> Yeah, you you have to as one of my
- 26:51colleagues say, you have to like not get
- 26:52frog boiled by it. Like like the
- 26:55>> [laughter]
- 26:55>> the temperature is rising
- 26:57and it's easy to
- 26:58I don't know. Anyway,
- 27:00so so there is this interesting gap so
- 27:03far. Like you might hear the phrase
- 27:05jagged frontier where the AI
- 27:08capabilities are jagged in the sense
- 27:10that they'll be superhuman in some on
- 27:13some axis and some you know, not
- 27:16superhuman still
- 27:17inferior in capability to human in in
- 27:20other axis on some other axis.
- 27:22And
- 27:24that
- 27:25remains the case so far in math.
- 27:28In particular, there's a couple things.
- 27:30In hindsight, the analysis by
- 27:32mathematicians of the solutions AI has
- 27:35found to these like big important
- 27:37previously unsolved math problems has
- 27:41it's always
- 27:42in first place, it's been nothing too
- 27:45super duper surprising. Maybe there was
- 27:48like a a direction that humans
- 27:52had overlooked or could have invested
- 27:55more in and AI sort of had the
- 27:58persistence. May maybe this is a good a
- 28:00good word or
- 28:02or the bravery or the temerity to like
- 28:04wade into these very in-depth intricate
- 28:07computations and calculations and sure
- 28:10enough came out the other side with with
- 28:12a solution. And humans look back and are
- 28:14like a
- 28:15that's not a crazy direction to try at
- 28:17all and maybe if we'd like gone in that
- 28:21direction, we we we would have come up
- 28:22with this. This isn't something that
- 28:24like would be surprising.
- 28:26>> What I'm curious about is
- 28:30are we seeing the AI systems come up
- 28:33with a solution to the problem or an
- 28:36algorithm to create the solution to the
- 28:40problem? And and
- 28:42I think I'm trying to like ask a lot of
- 28:44different things here. You know, one is
- 28:47like creative creativity, one is maybe
- 28:51levels of abstraction or the way it's
- 28:53like you know, thinking, abstracting,
- 28:55you know, around these problems. Um
- 28:59Yeah, I'll kind of pause and let you
- 29:01react to that.
- 29:02>> Yeah, let let let me let me throw out a
- 29:04couple things there. Let me know if you
- 29:06want me to expand on
- 29:07any of them.
- 29:09When humans solve these math problems,
- 29:11they they write up the solutions in
- 29:13paper and like papers, proofs that you
- 29:16know, this is true or this is not true.
- 29:18And those proofs are are not usually
- 29:21like not exactly algorithms. They're
- 29:22written in natural language. They have
- 29:24sort of
- 29:26They leave the reader to fill in some of
- 29:27the gaps. And
- 29:30AI systems are coming up with just the
- 29:31same kind of thing. Like like it's it's
- 29:34the same product. There's a lot of
- 29:35complaints about the writing style, but
- 29:37like the arguments, the substance of the
- 29:39arguments really are the thing we expect
- 29:42to see from humans such that if a human
- 29:45came up with this and yeah, maybe
- 29:46cleaned it up a little I don't know. Uh
- 29:49Like would be lauded for having like
- 29:51made a very insightful connection
- 29:54between two different areas or having
- 29:57gotten a an intricate
- 30:00argument just right and balanced
- 30:02different considerations to make
- 30:04everything come together to to land the
- 30:06proof. 100% like this is not a this is
- 30:10something where we're past the point
- 30:11where we can say, well, AI systems are
- 30:13sort of like
- 30:15not really doing something that humans
- 30:17would, you know, be impressed by on
- 30:19human terms. Now, AI systems are doing
- 30:21doing things that are
- 30:22>> And is there a way to categorize or
- 30:26qualitatively
- 30:28are we finding that and I think you
- 30:30spoke to this a little bit like are you
- 30:32know, is there a qualitative difference
- 30:34between you know, the best human
- 30:36approach and the AI approach in a sense
- 30:38of like
- 30:40you know, the AI brute forced it. You
- 30:43kind of spoke to this versus like pulled
- 30:45in things from some other domain and
- 30:48like created some elegant solution or
- 30:50are we past that point as well?
- 30:51>> Here I'd I'd give more nuance. Uh we we
- 30:55um
- 30:56there's an emerging sense of at least
- 30:59for the moment what an AI shaped problem
- 31:03looks like. Maybe I could say AI has two
- 31:06big advantages right now. One is it
- 31:08knows everything. Uh like it knows all
- 31:10the prior work. It's got the literature
- 31:12memorized. I'm speaking loosely, but
- 31:14that this is this is basically
- 31:17uh valid. Um
- 31:19the other is it's extremely patient and
- 31:21persistent. So if there is some
- 31:24intricate
- 31:25uh
- 31:26you know, calculation you have to do. I
- 31:28don't mean like numerically or
- 31:29algorithmically. When I say calculation,
- 31:31I just mean lots of equations and you
- 31:34have to make all the pieces work out
- 31:36just as a very high-level conceptual
- 31:38logical kind of computation, but still
- 31:41something very um intricate. Uh
- 31:45they just have the patience to to go for
- 31:47that. And if you take the Navier-Stokes
- 31:49example, I think it's not a coincidence
- 31:51that um OpenAI's reported uh system that
- 31:56that solved it included a swarm of
- 31:59thousands of different instances of AI
- 32:01systems trying lots of different things
- 32:03and sharing ideas where where where
- 32:05clearly it was able to like there is an
- 32:08element of brute force there.
- 32:10So there's degrees of brute force. This
- 32:12is where the nuance is. It wasn't like
- 32:14somehow uh
- 32:16you know,
- 32:17you you you asked it to like it wasn't
- 32:19solving this in by any means in the
- 32:21dumbest, most low-level way. Like we're
- 32:24we're past that point as well.
- 32:26They used to solve some problems in like
- 32:27kind of surprisingly low-level like
- 32:30grind it out kind of ways. Like that's
- 32:32not really what these look like anymore,
- 32:34but like the
- 32:35the high-level ver a higher-level
- 32:37version of that still is maybe what what
- 32:40you might what you might say here. So,
- 32:42and I like the frame of precise and
- 32:44intricate computations here. It's
- 32:47important I'll say one more thing about
- 32:49the Navier-Stokes solution. It's
- 32:51important to recognize that humans sort
- 32:53of put in place a lot of the structure
- 32:55through previous work that AI then went
- 32:58and as far as we can tell and humans are
- 33:00still figuring out exactly what goes
- 33:01into the AI solution, but as far as we
- 33:04can tell it builds on a lot of prior
- 33:07human work. The AI didn't like build it
- 33:08up from the ground. That kind of theory
- 33:11building as mathematicians call it, we
- 33:14still don't see that very much from AI
- 33:16systems.
- 33:17Last point I'll make before pausing on
- 33:19this is just uh
- 33:21remember it's point in time. Like
- 33:23remember that trajectory. We've seen
- 33:25very rapid uh so so mathematicians were
- 33:28saying we have to adapt our profession
- 33:30to the fact that now you can push a
- 33:31button and get what used to have been a
- 33:33career-making result. Like like you
- 33:36know, are also I think cautioning and we
- 33:38can't expect the capabilities will
- 33:40freeze right now. We we see, you know,
- 33:41that that linear whether it's linear or
- 33:44exponential is a matter of perspective,
- 33:46but it's going up.
- 33:47Uh and it's probably like we see no
- 33:49reason to expect it to stop there. So,
- 33:51this is a big thing Epoch is looking
- 33:53for. Can AI move from intricate
- 33:56computations plus lots of background
- 33:58knowledge to more of a
- 34:01developing uh new ideas more from whole
- 34:05cloth. Uh and and if so, and that's a
- 34:08big thing we're watching for in our in
- 34:09our own math benchmarking activities.
- 34:12>> Yeah, it's interesting to think that
- 34:17at least the way I characterize this as
- 34:18brute force versus pulling in things
- 34:21from other domains,
- 34:24those are
- 34:26um
- 34:27you know, those are not mutually
- 34:28exclusive. Like
- 34:30for for AI that has access to, you know
- 34:33all of the research from every domain,
- 34:35you know, an approach that could be very
- 34:38fruitful is to brute force the
- 34:39exploration of adjacent domains and pull
- 34:42that into the solution to a given
- 34:44problem.
- 34:45>> That's it, I think. A lot of what we see
- 34:48and maybe just to say the the other
- 34:50thing that would really supercharge them
- 34:53and bring them closer to full human
- 34:56parity or even human you know dominating
- 34:58human capabilities would be something
- 35:00like coming up with a new idea.
- 35:03And maybe like in calculus the idea of
- 35:07the derivative or the integral of a
- 35:08function. Like that was something that
- 35:10was you know maybe mathematicians in the
- 35:131500s had been like grasping for this
- 35:15idea and then Newton or Leibniz or
- 35:17whomever comes up with like hey, here's
- 35:20like I can I can describe a new thing, a
- 35:23new mathematical concept and that
- 35:25unlocks a lot for us. That lets us solve
- 35:28problems we previously couldn't solve.
- 35:31And so that's the sort of thing we don't
- 35:32yet see AI doing. It's also the sort of
- 35:35thing that's rarer for humans to do.
- 35:37Like a lot of human math progress has
- 35:39been well, I sat down and I put in the
- 35:41work and I did the computation and I
- 35:43worked out which was the dead end and
- 35:45which was the good path and here's the
- 35:46answer. Now XYZ is true. I've proven it.
- 35:50Or I studied one area and I noticed
- 35:52something and I thought it might be
- 35:54applicable to this nominally
- 35:55superficially different area. Like
- 35:56humans do that sort of stuff all the
- 35:58time. It is 90%
- 36:01vaguely speaking of human mathematical
- 36:02work from what I hear from
- 36:04mathematicians. The new idea stuff is
- 36:06rarer. So maybe we should expect it to
- 36:08be not the first thing AI gets good at.
- 36:10But so far we don't see AI really, you
- 36:13know, AI really doing that yet.
- 36:16>> How
- 36:17easy or difficult is it to
- 36:20define
- 36:21a new idea in such a way that
- 36:26you know we can easily distinguish them.
- 36:27Like, it it you know, if we think about
- 36:30kind of the evolution of this discourse
- 36:32around like, is it AI creative? You
- 36:35know, initially it was like, "Yeah, it's
- 36:36very creative. It created this like poem
- 36:38in, you know, in pirate. Like, that's
- 36:41creativity. That's, you know, that was a
- 36:42new idea." Uh but that's certainly not
- 36:45what we're talking about when we're
- 36:46talking about like advancing science,
- 36:49advancing mathematics, etc.
- 36:52Um
- 36:54Yeah, so how
- 36:55A A A how do we like
- 36:57how do we define that? But also, you
- 36:59know,
- 37:01from your perspective as someone who's
- 37:03studying this, is it like you know,
- 37:05we've got this long line of uh folks
- 37:07that are coming that says, "Here's this
- 37:09AI with a new idea." And you're like,
- 37:10"Yeah, well, let me evaluate it against
- 37:12my new idea criteria. No, it's not
- 37:14really that." Or
- 37:17are we actually like, is it pretty clear
- 37:19to everyone that the AI is not having
- 37:20new ideas and like, we're waiting for
- 37:23the first person to come and say that AI
- 37:25has the new idea? Like, how do you think
- 37:27about that whole space?
- 37:29>> Very very challenging nut to crack. Uh
- 37:32so, we, you know, try to approach it
- 37:35from different angles.
- 37:37One thing you can try to say is
- 37:42I've got a problem. I don't know if a
- 37:44new idea will be required to crack it.
- 37:47And this could be a problem in math or
- 37:48in science or or any quantitative area.
- 37:52But, humans have tried to crack it.
- 37:54Humans have tried to make, you know,
- 37:55this number go up, whether that number
- 37:57is the efficacy of some, you know, drug
- 38:00in fighting some disease or something
- 38:01like that. Or some you you know, or it's
- 38:04a math result of some you conjecture
- 38:07that that math have stumped
- 38:08mathematicians for a long time.
- 38:11And you can say, "Okay, well, I don't
- 38:12know if I'm not sure how I'm going to
- 38:14measure a new idea, but I can at least
- 38:16tell if this problem has been solved or
- 38:18this number has been made to go up." Or
- 38:21whatever that the concrete metric is.
- 38:24And you can then then you're you can at
- 38:26least check if that has happened. Now,
- 38:30I was probably a year ago more
- 38:31optimistic that there would be a tighter
- 38:34relationship between math problem that
- 38:37humans have failed to solve and post hoc
- 38:40qualitative assessment of creativity.
- 38:44Uh
- 38:45but uh but you know, that this is so
- 38:47this is sort of the combination that
- 38:49like, you know, double punch we're we're
- 38:51trying here. First you set a target
- 38:53that's hard on human terms that humans
- 38:55care about. The humans have tried to be
- 38:57creative to solve.
- 38:58And then you do post hoc review with
- 39:01experts and say, "What do you make of
- 39:02the solution? Why hadn't you found it?
- 39:05No offense.
- 39:06Uh you know, what what is in the AI
- 39:08solution that humans had missed and so
- 39:10on." And this is risky like risky in
- 39:13terms of humans being honest about it
- 39:15cuz you know, your your ego might be
- 39:17wrapped up in it or you might once you
- 39:19see the solution it feels more obvious
- 39:21in hindsight. So would you have
- 39:22described it like very very very risky
- 39:25uh but but you still you you try your
- 39:27best. And you know, you might say things
- 39:29like, "Well,
- 39:31uh how like here's an interesting
- 39:32approach that that we haven't
- 39:34operationalized in like in detail but
- 39:36it's it's a nice heuristic I think. How
- 39:38big a hint would a human have needed to
- 39:41solve this in in hindsight? Uh
- 39:44So for example, that unit distance a
- 39:47very prominent mathematician Fields
- 39:49medalist Tim Gowers
- 39:51did this sort of exercise on this unit
- 39:53distance problem once AI had solved it
- 39:55saying, "How big a hint and how like
- 39:59specific of a hint would I do I think a
- 40:01mathematician would have needed now in
- 40:03hindsight like to solve this problem?"
- 40:06Uh one one Yeah, and he came away with
- 40:09like an interesting exploration of well,
- 40:10actually AI sort of disproved this
- 40:12conjecture as opposed to proving it
- 40:14true. It said, "Actually, it's false."
- 40:15Even that is a huge hint. Humans had
- 40:17mostly thought it was true. They were
- 40:19wrong, but they've been trying to prove
- 40:20that it was true instead of looking for
- 40:22a counterexample. So, even just the hint
- 40:24of try to find a counterexample is
- 40:26pretty big. And then there was like one
- 40:28more piece and he was like, I think
- 40:30though very hard to say, we can't really
- 40:32do the counterfactual experiment. I
- 40:34think with just that
- 40:35with the like the sort of two-part hint
- 40:37it would have been possible for like a
- 40:39human would be like, oh, oh, okay, I
- 40:40know what to do now, blah, blah, blah,
- 40:41and like probably would have at least
- 40:43hastened a human solution. So, you can
- 40:45do things like that. It may be still
- 40:47very qualitative, but you try to be
- 40:49honest with yourself and be rigorous.
- 40:50And you could imagine doing a more
- 40:52rigorous version of this experiment. Uh
- 40:55and anyway, things like that. But then
- 40:56the the the fact is math is still for
- 40:59the most part a um
- 41:02a sort of discipline removed from
- 41:05physical real-world impact. Uh not
- 41:07always, but in surprise its impact is
- 41:09often hard to predict. There are domains
- 41:11where impact is not at all hard to like
- 41:13I'm in the chemistry lab and I'm trying
- 41:14to improve the yield of my synthesis
- 41:17process. And if AI you know, makes
- 41:19incremental improvements, I expect
- 41:21incremental yield. And if AI suddenly
- 41:22comes and says, "No, no, no, you're
- 41:24doing it all wrong. Let me like redesign
- 41:26your whole thing from scratch. I've got
- 41:27like a you know, maybe creative idea."
- 41:29Well, at some point you don't care if
- 41:30it's creative or not in the qualitative
- 41:32sense. You just care that you had saw a
- 41:34discontinuity in the yield of your
- 41:36chemical substance or whatever. And
- 41:38that's, you know, that's uh
- 41:40that that's a bigger bigger impact for
- 41:43the world anyway.
- 41:44>> What I took from that is that we filter
- 41:46on the problem and how hard humans have
- 41:48kind of banged their head heads against
- 41:50the problem. Then we look at the results
- 41:54that AI has come up with and try to kind
- 41:58of subjectively say, you know, is this
- 42:01based on a new idea or is it, you know,
- 42:03more brute force or something else like
- 42:06um but it's kind of imperfect and messy
- 42:09and like we're
- 42:10not really sure, but we're we don't
- 42:13think that we've come up with, you know,
- 42:15great examples of AIs coming up with
- 42:18uh you know,
- 42:20new quote unquote new ideas.
- 42:23>> W- One That's exactly right. W- One
- 42:25reference point I'd give is way back in
- 42:27uh
- 42:28gosh, well, the
- 42:29the teens. I forget which year the the
- 42:32famous Go playing system, the game of
- 42:34Go, AlphaGo. Uh that played
- 42:36>> had that thought earlier as we were
- 42:38discussing this. Like,
- 42:40if I remember correctly, the
- 42:43the
- 42:44you know, part of the solution was like,
- 42:47"Oh, that was an innovative move that no
- 42:48human ever would have done."
- 42:50>> There was a specific one. Yeah, exactly.
- 42:52>> a very specific move in there, yeah.
- 42:54>> Yeah, they call it move 37 cuz it was
- 42:57the 37th move in this game where uh
- 43:01yeah, apparently this was a very
- 43:03surprising move. Like you said, no human
- 43:05would have done it um in this particular
- 43:08position in this in this game of Go. And
- 43:12I think it's like encouraging for our
- 43:14admittedly quite subjective program here
- 43:17that Go experts looked at and were like,
- 43:19"Oh my goodness, like that's not, you
- 43:20know, that's that's new." And then it
- 43:23also became clear that that was pivotal,
- 43:25that that move gave the AI system
- 43:28playing Go a decisive advantage. And so
- 43:31that's sort of what we're looking for in
- 43:33in math. And at least, you know, maybe
- 43:35we have some hope that humans will be
- 43:37able to spot it when it happens. Uh but
- 43:40but yeah, that's that's what we haven't
- 43:41seen quite yet. And again,
- 43:45the trajectory's fast. The things are
- 43:47always a little more qualitative than y-
- 43:50you know, that you know, than they are
- 43:52or or continuous than discrete.
- 43:55Uh but, you know, so anyway, this is
- 43:56this is where we are now, which is kind
- 43:58of wild in its own right.
- 43:59>> Earlier when we were talking about
- 44:01frontier math, you kind of characterized
- 44:03it as, you know, one to four, I think,
- 44:06and then advanced. and we never circle
- 44:08back to
- 44:09>> Yeah, we we've got a couple we've got a
- 44:11couple uh two new sets of frontier math
- 44:14problems. We ditched the tier system,
- 44:16whatever.
- 44:17>> Okay.
- 44:17>> Uh so so now um these are what
- 44:21I'll lump them together cuz cuz it
- 44:23really is the
- 44:24the this is our our main tool. So we
- 44:26have uh
- 44:28you know, our latest iteration on
- 44:30frontier math uh consists of a bunch of
- 44:32problems that humans have tried and
- 44:34failed to solve. They're curated to be
- 44:36of a special interest to mathematicians
- 44:39where and some of them we've
- 44:41characterized even on a bit of a scale
- 44:43from like this would be moderately
- 44:46interesting or this would be like maybe
- 44:49what that means is
- 44:51two teams of mathematicians have tried
- 44:54this problem. It's at least 10 years
- 44:55old, but it's not central to any
- 44:57research program. It's just something
- 44:59that people would be happy to get an
- 45:00answer to. All the way up to like a
- 45:02major breakthrough.
- 45:04The four tiers here, breakthroughs the
- 45:06highest. Uh none of the breakthroughs
- 45:07have been solved yet, but don't get me
- 45:09wrong. If Navier-Stokes had been in this
- 45:11problem set, it would surely be a
- 45:13breakthrough there. Um regardless of the
- 45:15fact that humans had like done a lot of
- 45:18work and gotten maybe within spitting
- 45:20distance of the of the solution before
- 45:22AI finished it off. Um but yeah, we
- 45:24really view this as just uh a way of
- 45:27finding
- 45:28AI um
- 45:30a way of finding cases where AI might
- 45:33have had a creative idea because we can
- 45:36tell easily whether it solved these
- 45:38problems. This is maybe the the the big
- 45:40piece of work on our side was to make it
- 45:42easy to verify automatically whether an
- 45:45AI system has solved this problem. It's
- 45:47not obvious when you think about it that
- 45:49no human knows the answer. So how do you
- 45:50tell without a human looking if AI has
- 45:53has found the answer? But there's a
- 45:54couple techniques you can use for this
- 45:56and and we employ different techniques
- 45:58for this. Um we can go into that, but
- 46:00it's something of a technical detail.
- 46:02And so [clears throat] when we when a
- 46:04new model comes out, Astra came out, we
- 46:06hit go, and it's like, oh, it solved
- 46:09three new three new problems from our
- 46:10list. Okay, let's go look at the
- 46:11solutions. Let's share them with
- 46:13mathematicians. Let's see what's going
- 46:14on here.
- 46:15And and then we we analyze that. We with
- 46:18the help of mathematicians analyze that
- 46:19for like what kind of qualitatively what
- 46:21kind of solution was this.
- 46:23>> What does it mean when the models are so
- 46:25good that we have to shift from, you
- 46:28know, these benchmarks that we
- 46:29understand to like this collection these
- 46:31collections of problems that we just
- 46:33don't have the answers to?
- 46:34>> It's definitely a phase transition in
- 46:35the
- 46:37the science of AI capabilities
- 46:39measurement, which which is you know,
- 46:41what what I work on. But but it doesn't
- 46:43change the it doesn't change the game
- 46:46all that much. It just means we have to
- 46:48look for harder problems. Uh
- 46:50I think I joke sometimes that even
- 46:52certain forms of
- 46:54optimization problems like
- 46:57allocating scarce resources efficiently,
- 46:59that's a benchmark of sorts that will
- 47:01survive the singularity. Like even if AI
- 47:04is like off going crazy running rampant
- 47:07in the galaxy, it'll still have to you
- 47:08know, it'll still have to decide how to
- 47:11you know, optimize. So optimization is
- 47:14is always going to be a benchmark even
- 47:16if we're superhuman. Basically, it used
- 47:18to just be we knew the answers ahead of
- 47:19time. Now we don't. So it takes this
- 47:22extra trick of, okay, how do we tell
- 47:23when AI has gotten something right? But
- 47:26this isn't this isn't insurmountable.
- 47:29Especially like I would say with um
- 47:31you know, numbers in a scientific
- 47:32context. It's intuitive that okay, the
- 47:34best humans were able to do was, you
- 47:36know, X. But we just say to AI, hey, try
- 47:39to do Y greater than X. And, you know,
- 47:42if it does, that's, you know, those
- 47:44numbers go on and on. So it's it's no
- 47:46problem. But yeah, you're right to sort
- 47:48of note the the phase shift and to be
- 47:51somewhat surprised by it. Yeah.
- 47:53>> And is there a methodology, a concrete
- 47:55methodology for assessing and awarding
- 47:58partial credit. Is that part of the way
- 48:00you think about uh benchmarks in this uh
- 48:04you know, post phase shift?
- 48:06>> Yeah, it's a good question. It depends
- 48:07on the benchmark. So, sometimes it's
- 48:09something like, well, you just want to
- 48:11make this number go up and the higher
- 48:12the better. So, partial credit is very
- 48:14uh continuous and very very natural in
- 48:17those cases. For math problems,
- 48:19sometimes it's just like, well, what we
- 48:20care about is is you know, if X does Y
- 48:24always hold? Like like is this is this
- 48:26always true? And then it's kind of you
- 48:29sometimes humans will find and publish
- 48:31partial results for the AI systems. We
- 48:33usually just say, you know, all or
- 48:35nothing, but we have a large enough
- 48:36collection of such conjectures that, you
- 48:39know, we hope to have some, you know,
- 48:40smooth gradient of, well, okay, this one
- 48:43got two more out of 100 or something.
- 48:45And so so it uh you know, looks like a
- 48:48pretty smooth signal. Um that that's
- 48:50typically how we how we approach these
- 48:52things uh
- 48:53yeah, across benchmarks.
- 48:55>> Yeah, maybe what I was thinking was, you
- 48:57know, once you're in the regime of very
- 49:00challenging unsolved problems, is it
- 49:03possible that AI
- 49:06systems are doing, you know, surprising
- 49:08or novel or creative things, but still
- 49:10not quite getting them to the full uh
- 49:14you know, the full solution? And do we
- 49:15care about that? Do we want to to track
- 49:18that? And is that part of the way you've
- 49:20constructed the benchmark?
- 49:21>> It's a great question. Uh it's not
- 49:23central to how we construct the
- 49:24benchmark. Like it's probably like it's
- 49:26certainly worth tracking. The The
- 49:27problem is it's just a labor intensive.
- 49:29Uh like you could have AI review the AI.
- 49:31We We do this occasionally. Say like,
- 49:34"Which problems did it make partial
- 49:35progress on? What if we let it think for
- 49:37longer on those problems?" And nothing
- 49:40yet. Like it doesn't seem good at
- 49:41understanding how close it is to a
- 49:43solution. Humans aren't necessarily very
- 49:45good at this either.
- 49:47I did want to mention that while we
- 49:49focused on maybe the area where AI is
- 49:53the very best, like has come the
- 49:55farthest, the fastest, math. We do see
- 49:58lots of areas where we also think it's
- 50:01important to measure AI capabilities,
- 50:03where it's um
- 50:06where the progress is somewhat fuzzier,
- 50:08less clear, and certainly less
- 50:10superhuman, or even in even in some,
- 50:13well, may
- 50:14may be still superhuman in some ways,
- 50:16but the ways in which it's not yet are
- 50:19maybe more obvious and feel less
- 50:21rarefied. Uh
- 50:22>> What are some examples?
- 50:23>> A couple couple examples.
- 50:26One area that
- 50:27forthcoming work we're excited about is
- 50:29just
- 50:30it's a question everyone must be
- 50:32wondering, can AI take my job?
- 50:34So, our
- 50:35our job at Epoch often involves many
- 50:38things and
- 50:40all sorts of research, not just AI
- 50:42benchmarking, but other topics about
- 50:44trends in AI and uh writing research
- 50:47reports and doing data analysis, making
- 50:49info graphics that are, you know, make a
- 50:52point in an easy-to-digest way.
- 50:54We've been collecting examples of these
- 50:57from within Epoch, where the judgment at
- 51:02the end of did the AI system manage to
- 51:04do this, you know, Epoch task, um
- 51:08it is too messy for traditional
- 51:10benchmarking.
- 51:11So, it wouldn't be obvious like how to
- 51:14say did it get the right answer or not.
- 51:16It's not about making a number go up.
- 51:18It's not about satisfying some logical
- 51:20chain of deductions. It's like, here's
- 51:22the infographic to go along with this
- 51:24report. Like, does it does it meet our
- 51:26style guide and does it look good and
- 51:29does it, you know, is it better or worse
- 51:31than the
- 51:32the human reference that that we, you
- 51:35know, one of my colleagues did.
- 51:37Um
- 51:38And here we see like an interesting mix
- 51:41of
- 51:41some things I think we we sort of all
- 51:44our experience is like, yeah, if you ask
- 51:45it for a summary of the literature, it's
- 51:47going to do a pretty good job. It's like
- 51:49very good at that." But but there's
- 51:50other tasks where it's um, you know,
- 51:52hard like creating compelling visuals
- 51:55that follow our style guide. Or, this is
- 51:57a good one, coming up with a new um,
- 52:01like
- 52:02uh,
- 52:03short-form data-driven insight. Uh, we
- 52:06call these data insights. You can find
- 52:08them on our website. And uh, these like
- 52:11often we try to boil down a single like
- 52:14important observation into a single
- 52:16chart and a single sentence. Uh, and
- 52:19this is like this is hard. Uh, but we
- 52:21don't see them doing a great job at
- 52:22this.
- 52:23Come up with a new project for Epoch to
- 52:26undertake and do a prototype. Very
- 52:28open-ended. Not so good at this. Like
- 52:31like these more open-ended tasks, we we
- 52:33do see Again, my guess is if we we'll do
- 52:36this, go back in time some and see how
- 52:38models gotten better at this. My guess
- 52:40is we'll see progress. But the level
- 52:42compared to like humans is still a
- 52:44little
- 52:46still a little meh.
- 52:48I want to give one other example, uh,
- 52:50um, which is learning on the fly. This
- 52:53is a case where This is another case
- 52:55relevant for Ken AI take my job, cuz you
- 52:57didn't start you you weren't great at
- 52:59your job on day one, but as you
- 53:02practice, you know, you got better and
- 53:04humans, you know, have this sort of it
- 53:06you know, they learn on the fly. Uh, we
- 53:08take a
- 53:10we like to measure this for AI. We have
- 53:11a a benchmark that's taking a
- 53:13complicated board game. We did a human
- 53:15study for for saying, "How many times do
- 53:17humans have to play this board game in a
- 53:19row before they sort of figure out how
- 53:21it works and can get a very high score
- 53:23on it?" And we do the same with AI. We
- 53:25say, "Play it once, take notes." Same AI
- 53:28instance, like play it again, take
- 53:30notes, play it again, take notes, and
- 53:32see how you can do. AI systems have
- 53:33gotten good at this board game, but not
- 53:36by playing it repeatedly. It's more of a
- 53:38intergenerational thing. Like GPT 5.6
- 53:42scores X out of the box and then stays
- 53:44flat on its play throughs. GPT 6 scores
- 53:47much higher. It's like much better at
- 53:48it, but it's still out of the box and
- 53:50then it stays flat in its play throughs
- 53:52and it's still less than the top human.
- 53:54So, that this kind of on the fly
- 53:56learning is something we also don't see
- 53:57AI systems as being good enough at even
- 54:00to just pick up a board game, let alone
- 54:02a messier
- 54:04job, you know, real world job like that.
- 54:06So, these are sorts of things where we
- 54:08don't see these capabilities and we
- 54:09think it's important to try to catch
- 54:11when they emerge.
- 54:12>> My gut on the the ladder, the AI
- 54:16learning on the fly is that it's maybe a
- 54:19harness solvable challenge versus a
- 54:22model solvable challenge and maybe you
- 54:25know, no one's focused on that.
- 54:27Like
- 54:28with the right set of memory structures
- 54:30and like some kind of side car
- 54:33heuristic-y thing, like
- 54:35you know, we can probably make a big
- 54:37step improvement in
- 54:40an AI's ability to like
- 54:43you know, improve game to game, but it's
- 54:45not
- 54:46uh it might not require dramatic model
- 54:50changes. Do you do you think about that
- 54:53and is is do you have, you know, in this
- 54:57domain or in other domains like
- 55:00formal or structured ways of thinking
- 55:02about you know, what
- 55:05uh you know, model versus harness. You
- 55:07know, granted this whole model versus
- 55:09harness thing in and of itself is, you
- 55:11know, practically brand new,
- 55:13um
- 55:14but it's proving to be important in, you
- 55:17know, distinguishing, you know, where
- 55:19the these improvements come from.
- 55:21>> Uh yeah, definitely. Uh
- 55:25it We've done some experiments on this
- 55:27for the board game case in particular,
- 55:30where we've tried uh
- 55:33uh very simple harness first the first
- 55:35party harnesses like Claude code or code
- 55:37acts. We've tried multi-agent setups.
- 55:40We've tried like we we give them you
- 55:43know, note-taking tools and say you
- 55:45know, make it clear like okay,
- 55:47you you're you're you're goal is to
- 55:48learn the game so you can do really well
- 55:50like in your final plays of the game. So
- 55:52explore, take notes, figure out like we
- 55:54try to prompt them well.
- 55:56I mean we want to find good results if
- 55:58we can cuz it's like that's a big deal
- 56:00for the world.
- 56:01The game is a test bed but real jobs
- 56:04would also you know, benefit
- 56:06significantly. Risks would also go up if
- 56:08this capability, you know, you test in
- 56:10the lab is it a great hacker? You find
- 56:12maybe it is, maybe it isn't but if you
- 56:14find that it isn't and yet it can learn
- 56:15on the fly then okay, once you deploy it
- 56:17like look out. Um
- 56:19So anyway, we we try we've tried pretty
- 56:21hard and have mostly not found anything
- 56:24that cracks this
- 56:26that cracks this on-the-fly learning.
- 56:28There's been some general research about
- 56:29this as well, not just us about
- 56:32you know, people talk like there was a
- 56:34people say it uses these so-called
- 56:36skills where you like just write some
- 56:38notes to an AI system of look, when you
- 56:41do work I ask you to do you're going to
- 56:43need to use this tool or produce this
- 56:45kind of output and like here's my notes
- 56:47on how you could do that well so you
- 56:48don't have to like learn it on the like
- 56:51pick it up fresh every time. So use
- 56:53these skills.
- 56:54And these show some improvement but then
- 56:56there's like a plateau like pretty
- 56:57quickly
- 56:58at least in the the research I'm
- 57:00familiar with of like you can get some
- 57:02improvements. My sense is that this is
- 57:04very loosely speaking
- 57:06it's like low-hanging fruit. Like if
- 57:08you're telling it oh you're going to
- 57:09have to navigate this like finicky
- 57:11website that my company makes me use and
- 57:13like just you're going to get stuck and
- 57:15like you have to look in this menu and
- 57:16that's where the button you're looking
- 57:17for like straightforward advice that's
- 57:20like obviously useful. But when it comes
- 57:22to higher-level strategic
- 57:24thinking kind of hard to bake that into
- 57:26the harness
- 57:28where or or or like where where the the
- 57:31board game plays like like has this um
- 57:34you know sort of brings this out where
- 57:36it's like there's not any perfect advice
- 57:40that like you have to find the advice
- 57:42for yourself in a sense. Like you have
- 57:44to learn the game. Like so I will say if
- 57:46we give it extremely detailed strategy
- 57:48guides for here's how you beat this
- 57:50game. Like here's everything you could
- 57:52possibly like it's a cheat by human like
- 57:54no one would play the game that way.
- 57:56They do very They do very well. They do
- 57:59much better than if they basically have
- 58:01to find that for themselves.
- 58:02>> right creating the strategy guide.
- 58:04>> They can't create the strategy guide for
- 58:06themselves which is like pretty
- 58:07interesting. So so like we do expect
- 58:10eventually they'll get better at this
- 58:12but it's again it's a big deal if that
- 58:14if that happens because now it means
- 58:16okay
- 58:18go back to that first benchmark suite.
- 58:20Okay, they're not great at making charts
- 58:23for us or coming up with data insights
- 58:25for us you know without guidance. But
- 58:29now put them in on the team for a little
- 58:31while and let them learn on the fly and
- 58:34maybe they do become good. So you sort
- 58:36of see these as a combination like if on
- 58:38our board game where it's easy to
- 58:40measure they're not getting better over
- 58:41time then it's okay for us over in the
- 58:43real world like human in the loop
- 58:45evaluation
- 58:47studies for us to just do one try and
- 58:49say okay well they weren't great and we
- 58:51don't think they learn on the so that
- 58:52you know but but really you know those
- 58:54go together.
- 58:55>> And is the board game a synthetic one
- 58:58that you created for this challenge or
- 59:01is it a a real board game that that
- 59:03people play?
- 59:04>> It's a real board game. It's called
- 59:06the first one we did this with we'll do
- 59:07this with more
- 59:08is called Earthborn Rangers.
- 59:10It's fairly obscure. If you go to like
- 59:12boardgamegeek
- 59:14.com it's like 500th most popular or
- 59:17something. So it's not like up there.
- 59:19There's a small devoted community to it
- 59:22and
- 59:23AI systems don't seem to know that much
- 59:25about it. Like they've heard of it. They
- 59:26can give you some facts about it, uh
- 59:28but it doesn't seem like something
- 59:30they've been trained on specifically.
- 59:32It's impossible for us to tell this with
- 59:34with high certainty, with high you know,
- 59:35high confidence, but but that's sort of
- 59:37why we chose it. Um
- 59:39it's just hard to make these things from
- 59:40scratch and know whether they're hard or
- 59:42whether they're broken. Uh you know, so
- 59:44that's why we But but the risk which you
- 59:46might have in mind is what if AI systems
- 59:48like you know, just know about it from
- 59:50their training data. That's a risk on
- 59:52our mind. It's just a risk. One thing we
- 59:54will do in the future is we're moving on
- 59:56to video games. Incidentally, it's
- 59:57another area where AI is like very much
- 1:00:00not like human reaction time and visual
- 1:00:02and spatial reasoning. Again, coming
- 1:00:04along fast, but not uh not really there
- 1:00:07yet. Um
- 1:00:09that So, video games, you can always
- 1:00:11test on a new game, like a a game that
- 1:00:12just came out, uh not in the training
- 1:00:14data probably.
- 1:00:16Um or at least, you know, not as
- 1:00:17robustly in the training data.
- 1:00:20Uh and so we'll be testing can AI
- 1:00:21systems do well on those? Do they do
- 1:00:23better on like, you know, the older
- 1:00:26version of a video game than like, you
- 1:00:28know, Grand Theft Auto 4 vs. 5 or
- 1:00:30whatever. Uh like when GTA 6, whatever
- 1:00:33it is, comes out, like I I don't think
- 1:00:35we'll we'll be doing this one, but but
- 1:00:37you know, are they worse at that?
- 1:00:38>> It's interesting when you when you bring
- 1:00:41up video games, it immediately calls to
- 1:00:43mind kind of the classical reinforcement
- 1:00:46learning approaches, which is kind of
- 1:00:49learning on the fly, but kind of
- 1:00:51different.
- 1:00:51>> Yeah, we we call the second sometimes in
- 1:00:53context learning, where the only like
- 1:00:55lever the AI system really has is
- 1:00:57managing its context. And like look,
- 1:01:00when we give it the strategy guides and
- 1:01:01they do much better, clearly this is a
- 1:01:03powerful lever, but it's not as powerful
- 1:01:06as updating the weights. And like So,
- 1:01:08yeah, I I I mean like what's the big
- 1:01:10picture here? It's it's if you have this
- 1:01:12fast loop of in context on the fly
- 1:01:14learning, uh then AI capabilities might
- 1:01:18sort of improve much more rapidly than
- 1:01:19the slower loop of uh collecting more
- 1:01:23training data, doing more reinforcement
- 1:01:24learning, which which is done on
- 1:01:27language models as well these days.
- 1:01:29Um
- 1:01:30and then deploying a new model. Now, AI
- 1:01:32might automate that whole loop, but
- 1:01:33it'll still be slower than if it can
- 1:01:35just, you know, work out its
- 1:01:37its own context on the fly, yeah.
- 1:01:40>> Yeah, it's interesting when you zoom out
- 1:01:42on some of the the questions that you
- 1:01:45focus on, and we haven't talked
- 1:01:47explicitly about it, but you have a blog
- 1:01:49post where you kind of
- 1:01:52uh write out these nine big hairy
- 1:01:55questions that you're tracking.
- 1:01:57They kind of group into like, how do I
- 1:02:00assess where AI is now? That's like, can
- 1:02:02it do my job? Like, how is it, you know,
- 1:02:05uh competitively?
- 1:02:07Uh and you know, where is the puck
- 1:02:10going? Like, can it learn on the fly?
- 1:02:12You know, can it do research? Can it
- 1:02:14come up with new ideas? These are all
- 1:02:16It's kind of where it is now, but also
- 1:02:18like, what what you know, is it
- 1:02:21positioned to like dramatically
- 1:02:23um
- 1:02:25you know, self-improve or like, you
- 1:02:27know, what's the trajectory?
- 1:02:29>> That's exact That's exactly right.
- 1:02:31The um
- 1:02:33I mean, I think
- 1:02:34for for people thinking more broadly
- 1:02:36about what they need to know about AI,
- 1:02:39that this is the second topic is
- 1:02:43uh
- 1:02:43you know, just as important as the
- 1:02:45first. Uh but
- 1:02:47it's really
- 1:02:49you know, even if you take some of the
- 1:02:50recent incidents like the the hugging
- 1:02:52face incident, like
- 1:02:54the sort of think of two axes.
- 1:02:56Alignment of is the AI doing what I want
- 1:02:59it to do holistically? Obviously,
- 1:03:01hacking into some other company's
- 1:03:03computers is not well aligned. Uh and
- 1:03:05then capabilities, just like, what can
- 1:03:07it get done? Uh can it hack into uh you
- 1:03:10know, reasonably well-secured other
- 1:03:12companies'
- 1:03:13uh computers?
- 1:03:15Um
- 1:03:16what that incident was was like an early
- 1:03:18example, very like, I think pretty
- 1:03:20robust example of well, we don't have
- 1:03:22the alignment thing solved and capab-
- 1:03:25and capabilities are getting so big, so
- 1:03:28strong that this is becoming a problem.
- 1:03:31Uh, and so paying attention to
- 1:03:32capabilities like what we should expect
- 1:03:35is becoming more important sort of
- 1:03:37day-to-day and we're just trying to
- 1:03:38produce benchmarks that both say, where
- 1:03:42are we now? Exactly like you said, like
- 1:03:44what can it do now? Uh,
- 1:03:45this is maybe relevant for more, you
- 1:03:49know, mundane economic utility or
- 1:03:51whatever, as well as, uh,
- 1:03:53you know, do we see the the dynamics of
- 1:03:56the system changing in a way that might
- 1:03:58be alarming, basically.
- 1:04:00>> You're kind of also thinking about it as
- 1:04:01like first and second derivative of
- 1:04:03capability.
- 1:04:04>> Yeah, I think that's right. Uh, some of
- 1:04:06these things make it, uh,
- 1:04:08the slope goes, you know, much, uh, you
- 1:04:11know,
- 1:04:12faster, uh, hyp- hyperbolic growth or
- 1:04:14whatever in some of these cases versus
- 1:04:17merely just like, yep, it's, uh, it's
- 1:04:19growing and it continues to grow. Both
- 1:04:21are important. I mean, I think we've
- 1:04:22seen
- 1:04:23the disruption we've seen to date has
- 1:04:26come from these kind of unpredictable
- 1:04:29thresholds. Like when, you know, GPT-2,
- 1:04:32GPT-3, suddenly you had the ChatGPT
- 1:04:35moment and you're like, oh, this thing,
- 1:04:37I want to talk to this thing. I might
- 1:04:38use this thing instead of a search
- 1:04:39engine. This thing is useful to me for
- 1:04:40finding information. And then sud- and
- 1:04:42then like, you know, a little while,
- 1:04:44years later,
- 1:04:45whatever, 2 years later, you had the
- 1:04:47it's getting better slowly and steadily
- 1:04:49at helping me with coding or with like
- 1:04:51using my computer, but suddenly you have
- 1:04:53>> models.
- 1:04:54>> With the thinking models and then you
- 1:04:55had the Claude code moment where it was
- 1:04:58like, oh, suddenly this thing can
- 1:04:59actually do software projects for me
- 1:05:01even if I'm not a very not an engineer
- 1:05:03myself. Uh, and it's like hard to
- 1:05:05predict when these thresholds will be
- 1:05:07crossed. So, it's useful to still track
- 1:05:09but like the it's useful to track the
- 1:05:11mundane capabilities today and say,
- 1:05:13look, you know, cyber is maybe the
- 1:05:14latest example where it's like, look, we
- 1:05:16see their ability in controlled settings
- 1:05:18to do hacking going up
- 1:05:21smoothly and at some point it's going to
- 1:05:23cross some threshold where, oh shoot, it
- 1:05:25can hack hugging face or whatever. Hard
- 1:05:27to predict where those thresholds are,
- 1:05:29but still very useful to track those
- 1:05:32capabilities. So so even the first
- 1:05:34derivative as as you said version of
- 1:05:36this, we find very useful. We've got
- 1:05:40So a fun benchmark we hope hope to
- 1:05:42release maybe by the time this is
- 1:05:44published. We'll we'll we'll have it out
- 1:05:45on a furniture assembly where we you we
- 1:05:49build some IKEA furniture, make some
- 1:05:50mistakes and see if the AI system can
- 1:05:52like just given photos like say, oh like
- 1:05:55wait, you made a mistake in step back in
- 1:05:56step four like stop, go back.
- 1:05:59Um
- 1:06:00And they've you know, we see the same
- 1:06:01smooth capabilities like Astra GPT-6
- 1:06:04Astra pretty good at this actually.
- 1:06:06Uh and you know, but it wasn't out of
- 1:06:08nowhere. It was like from a smooth and
- 1:06:10this is you know, important because we
- 1:06:12haven't seen AI have much of an impact
- 1:06:14in physical industry yet. Like it's been
- 1:06:16mostly digital.
- 1:06:18Uh and even before robotics hit the
- 1:06:19scene hits the scene, we we might expect
- 1:06:22that you know, Claude in your glasses or
- 1:06:24something is saying like, hey, you know,
- 1:06:26I'm going to guide you through repairing
- 1:06:28your car or whatever. I'm going to help
- 1:06:29you fix this machine in the factory that
- 1:06:31broke. So so you know, we want to track
- 1:06:33those capabilities too just for the
- 1:06:34mundane impact. Anyway, impact all over
- 1:06:37the place coming. Benchmarks help us
- 1:06:39help us say so.
- 1:06:41>> Awesome. Awesome. Well, Greg, thanks so
- 1:06:42much for jumping on and sharing a bit
- 1:06:45about what you're working on. It's super
- 1:06:47interesting stuff and [music]
- 1:06:49very thought-provoking way of
- 1:06:51thinking about you know, AI and where it
- 1:06:53is, where it's going.
- 1:06:55>> Thanks, Sam. Really appreciate it.
- 1:06:57>> Awesome. Thank you.
- 1:07:18>> Mhm.
