Ilya Sutskever 離開 OpenAI 後首次深度專訪：人類學得比 AI 快，是因為我們有更好的演算法

You know what's crazy that all of this is real?

>> Yeah. Meaning what?

>> Don't you think so?

>> Meaning what?

>> Like all this AI stuff and all this area. Yeah. That it's happen. Like isn't

area. Yeah. That it's happen. Like isn't

it straight out of science fiction?

>> Yeah. Another thing that's crazy is like how normal the slow takeoff feels. The

idea that we'd be investing 1% of GDP in AI, like I feel like it would have felt like a bigger deal, you know, where right now it just feels like >> we get used to things pretty fast. Turns

out Yeah. But also it's kind of like it's abstract like what does it mean?

What it means that you see it in the news.

>> Yeah.

>> That such and such company announced such and such dollar amount, >> right?

>> That's that's all you see, >> right?

>> It's not really felt in any other way so far.

>> Yeah. Should we actually begin here? I

think this is an interesting discussion.

>> Sure.

>> I think your point about well from the average person's point of view nothing is that different will continue being true even into the singularity.

>> No, I don't think so. Okay. Interesting.

>> So the thing which I was referring to not feeling different is okay. So such and such company

is okay. So such and such company announced some difficult to comprehend dollar amount of investment >> right >> I don't think anyone knows what to do with that.

>> Yeah.

>> But I think that the impact of AI is going to be felt. AI is going to be diffused through the economy. There are

very strong economic forces for this.

And I think the impact is going to be felt very strongly.

>> When do you expect that impact? I think

the models seem smarter than their economic impact would imply.

>> Yeah, this is one of the very confusing things about the models right now. How

to reconcile the fact that they are doing so well on evals.

>> Mhm.

>> And you look at the evals and you go those are pretty hard evals, >> right? They're doing so well,

>> right? They're doing so well, but the economic impact seems to be dramatically behind. And it's almost

dramatically behind. And it's almost like it's it's very difficult to make sense of how can the model on the one hand do these amazing things and then on the

other hand like repeat itself twice in some situation in a kind of a an example would be let's say you use VIP coding to do something and you go to some place

and then you get a bug and then you tell the model can you please fix the bug?

>> Yeah. And the model says, "Oh my god, you're so right. I have a bug. Let me go fix that." And it introduces a second

fix that." And it introduces a second bug.

>> Yeah.

>> And then you tell it you have you have this new the second bug and it tells you, "Oh my god, how could I've done it?

You're so right again."

>> And brings back the first bug and you can alternate between those.

>> Yeah.

>> And it's like how is that possible?

>> Yeah.

>> It's like I'm not sure. But it does suggest that the something strange is going on. I have

two possible explanations. So here this is the more kind of a whimsical explanation is that maybe ARL training makes the models a little bit too single-minded and narrowly focused a

little bit too I don't know unaware even though it also makes them aware in some other ways and because of this they can't do basic

things but there is another explanation which is back when people were doing pre-training the question of what data to train on

was answered because the that answer was everything.

>> Yeah.

>> When you do pre-training, you need all the data.

So you don't have to think is it going to be this data or that data.

>> Yeah.

>> But when people do RL training, they do need to think. They say okay, we want to have this kind of RL training for this thing and that kind of RL training for that thing. And from what I hear, all

that thing. And from what I hear, all the companies have teams that just produce new RL environments and just add it to the training mix. And then the question is, well, what are those? There

are so many degrees of freedom. There is

such a huge variety of real environments you could produce. And one of the one thing you could do and I think that's something that is done inadvertently

is that people take inspiration from the evals. you say, "Hey, I would love our

evals. you say, "Hey, I would love our model to do really well when we release it. I want the evos to look great.

it. I want the evos to look great.

What would be RL training that could help on this task, right?" I think that is something that happens and I think it could explain a lot of what's going on.

If you combine this with generalization of the models actually being inadequate, that has the potential to explain a lot of what we are seeing. this disconnect

between eval performance and actual real real world performance which is something that we don't today exactly even understand what what we mean by that.

>> I I like this idea that the real reward hacking is a human researchers who are too focused on the evals. Um I think there's two ways to understand or to try

to think about what what you have just pointed out. One is look, if it's the

pointed out. One is look, if it's the case that simply by becoming superhuman at a coding competition, a model will not automatically become more tasteful

and exercise better judgment about how to improve your codebase. Well, then you should expand the suite of environments such that you're not just testing it on having the best performance in coding competition. It should also be able to

competition. It should also be able to make the best kind of application for X thing or Y thing or Z thing. And another

maybe this is what you're hinting at is to say why should it be the case in the first place that becoming superhuman at coding competitions doesn't make you a

more tasteful programmer more generally.

Maybe the thing to do is not to keep stacking up the amount of environments and the diversity of environments to figure out approach with let you learn from one environment and improve your

performance on something else.

So I have I have an anal a human analogy which might be helpful. So even the case let's take the case of competitive programming since you mentioned that and

suppose you have two students one of them work decided they want to be the best competitive programmer so they will practice 10,000 hours for that domain

>> they will solve all the problems memorize all the proof techniques and be very very you know be very skilled at quickly and correctly implementing all the algorithms and by

doing by doing so they became the best one of the best. Student number

two thought, oh, competitive programming is school. Maybe they practiced for 100

is school. Maybe they practiced for 100 hours, >> much much less, and they also did really well. Which one do you think is going to

well. Which one do you think is going to do better in their career later on?

>> The second, >> right? And I think that's basically

>> right? And I think that's basically what's going on. The models are much more like the first student, but even more because then we say, okay, so the model should be good at competitive programming. Let's get every single

programming. Let's get every single competitive programming problem ever and then let's do some data augmentation. So

we have even more competitive programming problems. >> Yes.

>> And we train on that. And so now you got this great competitive programmer. And

with this analogy I think it's more intuitive. I think it's more intuitive

intuitive. I think it's more intuitive with this analogy that Yeah. Okay. So if

it's so well trained, okay, it's like all the different algorithms and all the different proof techniques are like right at it at its fingertips.

And it's more intuitive that with this level of preparation, it not would not necessarily generalize to other things.

>> But then what is the um analogy for what the second student is doing before they do the 100 hours of fine-tuning?

>> I think it's like they have it. I think it's the it factor.

>> Yeah.

>> Right. And like I know like when I was in undergrad, I remember there was there was a student like this that studied with me. So I know I know it exists.

with me. So I know I know it exists.

>> Yeah. I think it's interesting to distinguish it from whatever pre-training does. So, one way to

pre-training does. So, one way to understand what you just said about we don't have to choose the data in pre-training is to say actually it's not dissimilar to the 10,000 hours of practice. It's just that you get that

practice. It's just that you get that 10,000 hours of practice for free because it's already somewhere in the pre-training distribution. But it's like

pre-training distribution. But it's like maybe you're suggesting actually there's actually not that much generalization from pre-training. There's just so much

from pre-training. There's just so much data in pre-training. Everybody's like

it's not necessarily generalizing better than RL.

>> Like the main the main strength of pre-training is that there is a so much of it.

>> Yeah.

>> And b you don't have to think hard about what data to put into pre-training >> and it's a very kind of natural data and it does include in it a lot of what

people do.

>> Yeah.

people's thoughts and a lot of the features of you know it's like the whole world as projected by people onto text.

>> Yeah.

>> And pre-training tries to capture that using a huge amount of data.

It's it's very the pre-training is very difficult to reason about because it's so hard to understand the manner in which the model relies on pre-training

data. And whenever the model makes a

data. And whenever the model makes a mistake, could it be because something by chance is not as supported by the pre-training data? You know, and pre

pre-training data? You know, and pre support by pre-training is maybe a loose term.

I I don't know if I can add anything more useful on this, but I don't think there is a human analog to pre-training.

Here's analogies that people have proposed for what the human analogy to pre-training is, and I'm curious to get your thoughts on why they're potentially wrong. One is to think about the first

wrong. One is to think about the first 18 or 15 or 13 years of a person's life when they aren't necessarily economically productive, but they are

doing something that is making them understand the world better and so forth. And the other is to think about

forth. And the other is to think about evolution as doing some kind of search for three billion years which then results in a human lifetime instance.

And then I'm I'm curious if you think either of these are actually analogous to pre-training or how how would you think about at least what lifetime human learning is like if not pre-training. I

think there are some similarities between both of these two pre-training and pre-training tries to play the role of both of these >> but I think there are some big differences as well.

The amount of pre-training data is very very staggering.

>> Yes.

>> And somehow a a human being after even 15 years with a tiny fraction of that pre-training data they know much less.

>> Yeah. But whatever they do know they know much more deeply somehow and the mistakes like like already at that age you would not make mistakes that our eyes make.

>> Yeah. There is another thing you might say could it be something like evolution and the answer is maybe but in this case I think evolution might actually have an

edge like there is this I remember reading about this case where some you know that one thing that neuroscientists do or rather one way in which

neuroscientists can learn about the brain is by studying people with brain damage to different parts of the brain >> and and so and some people have the most strange symptoms you could imagine. It's

actually really really interesting. And

there was one case that comes to mind that's relevant.

I read about this person who had some kind of brain damage that took out I think a stroke or an accident that took out his emotional

processing. So he stopped feeling any

processing. So he stopped feeling any emotion and as a result of that you know he still remained very articulate and he

could solve little puzzles and on tests he seemed to be just fine but he felt no emotion he didn't feel sad he didn't feel angry he didn't feel animated and

he became somehow extremely bad at making any decisions at all it would take him hours to decide on which socks to wear and he would make very bad

financial decisions And that's very does what what does it say about

the role of our built-in emotions in making us like a viable agent essentially >> and I guess to connect to your question about pre-training

>> it's like maybe pre- like maybe if you are good enough at like getting everything out of pre-training you can get you could get that as well but that's the kind of thing which seems

Well, it may or may not be possible to get that from pre-training. What is

that? Clearly not just directly emotion.

It seems like some almost value function like thing which is giving telling you which decision to be like what the end reward for any decision should be and you think that

doesn't sort of implicitly come from >> I think it could I'm just saying it's not one it's not 100% obvious.

>> Yeah. But what what is that like what how do you think about emotions in what is the ML analogy for emotions?

>> It should be some kind of a value function thing.

>> Yeah. But I don't think there is a great ML analogy because right now value functions don't play a very prominent role in uh the things people do.

>> It might be worth defining for the audience what a value function is if if you want to do that.

>> I mean certainly I I'll be very happy to do that. Right. So

do that. Right. So

so when people do reinforcement learning the way reinforcement learning is done right now how does it do how do people train those agents? So you have your neural net and you give it a problem and

then you tell the model go solve it and the model takes maybe thousands hundreds of thousands of actions or thoughts or something and then it produces a solution. The solution is

created and then the score is used to provide a training signal for every single action in your trajectory.

>> Mhm. So that means that if you are doing something that goes for a long time, if you're training a task that takes a long time to solve, you will do no learning at all until you solve the until you

came up with a proposed solution. That's

how reinforcement learning is done naively. That's how 01 R1 ostensibly are

naively. That's how 01 R1 ostensibly are done.

The value function says something like okay look maybe I could sometimes not always could tell you if you're doing well or badly. The notion of a value

function is more useful in some domains than others. So for example when you

than others. So for example when you play chess and you lose a piece you know I messed up. You don't need to play the whole

up. You don't need to play the whole game to know that what I just did was bad and therefore whatever um whatever preceded it was also bad. So the value

function lets you short circuit the weight until the very end. Like let's

suppose that you started to pursue some kind of um okay let's suppose that you are doing some kind of a math thing or a programming thing and you're trying to explore a particular solution direction

and after let's say after a thousand uh steps of thinking you concluded that this direction is unpromising.

As soon as you conclude this, you could already get a reward signal a thousand times steps previously when you decided to pursue down this path. You say, "Oh,

next time I shouldn't pursue this path in a similar situation long before you actually came up with a proposed solution." H this was in the deepcar one

solution." H this was in the deepcar one paper is that the space of trajectories is so wide that

maybe it's hard to learn a mapping from an intermediate trajectory and value and also given that you know in coding for example you'll have the wrong idea then you'll go back then you'll change something

>> this sounds like such lack of faith in deep learning >> like I mean sure it might be difficult but nothing deep learning can't too.

>> Yeah.

>> So my expectation is that like value function should be useful and and I fully I fully expect that they will be used in the future if not

already. What was I alluding to with the

already. What was I alluding to with the person whose emotional center got >> um damaged is more that

maybe what it suggests is that the value function of humans is modulated by emotions in some important way that's hardcoded by evolution

and maybe that is important for people to be effective in the world.

>> That that's the thing I was actually kind of planning on asking you. There's

something really interesting about emotions as a value function, which is that it's impressive that they have this much utility while still being rather

um simple to understand.

So I have two responses. I do agree that compared to the kind of things that we learn and the things we are talking about, the kind of ads we are talking about, emotions are

relatively simple.

They might even be so simple that maybe you could map them out in a human understandable way. I think it would be

understandable way. I think it would be cool to do.

In terms of utility though, I think there is a thing where you know there is this complexity robustness trade-off

where complex things can be very useful but simple things are very useful in very broad range of situations. And so I think what what one way to interpret

what we are seeing is that we've got these emotions that essentially evolved mostly mostly from our mammal ancestors and then fine-tuned a little bit while

we were homminids just a bit. We do have like a decent amount of social emotions though which mammals may lack but they're not very sophisticated

and because they're not sophisticated they serve us so well in this very different world compared to the one that we've been living in. Actually they they also make mistakes for example our emotions well I don't know does hunger

count as an emotion deate it's debatable but I think for example our intuitive feeling of hunger

is not succeeding in guiding us correctly in this world with an abundance of food.

>> Yeah people have been talking about scaling data scaling parameters scaling compute.

Is there a more general way to think about scaling? What are the other

about scaling? What are the other scaling axes?

>> So the thing so so here here is a perspective here's a perspective I think might be might be true.

So the way ML used to work is that people would just think of it with stuff and try to

and try to get interesting results.

That's what's been going on in the past.

Then the scaling insight arrived right scaling laws GPT3 and suddenly everyone realized we should

scale and it's just this this is an example of how language affects thought.

Scaling is what just one word but it's such a powerful word because it informs people what to do. They say okay let's let's try to scale things. And so you say okay so what are we scaling and

pre-training was a thing to scale it was a particular scaling recipe.

>> Yes >> the big breakthrough of pre-training is the realization that this recipe is good. So you say hey if you mix some

good. So you say hey if you mix some compute with some data into a neural net of a certain size you will get results and you will know that it will be better

if you just scale the recipe up. And

this is also great. Companies love this because it gives you a very uh lowrisk way of investing >> your resources.

>> Yeah.

>> Right. It's much harder to invest your resources in research. Compare that. You

know, if you research, you need to have like go forth researchers and research and come up with something versus get more data, get more compute. You know,

you'll get something from pre-training.

And indeed, you know, it looks like I based on various um um things people say on some people say on Twitter, maybe it appears that Gemini have found a way to get more out of

pre-training. At some point though,

pre-training. At some point though, pre-training will run out of data. The

data is very clearly finite. And so

then, okay, what do you do next? Either

you do some kind of a souped-up pre-training, different recipe from the one we've done before, or you're doing a RL, or maybe something else. But now

that comput is big, computer is now very big. In some sense, we are back to the

big. In some sense, we are back to the age of research. So maybe here's another way to put it. Up until 2020, from 2015, from 20 2012 to 2020, it was the age of

research. Now from 2020 to 2025, it was

research. Now from 2020 to 2025, it was the age of scaling or maybe plus minus.

Let's add the arrow bars to those years because people say this is amazing. You

got to scale more. Keep scaling. The one

word scaling. But now the scale is so big. Like is is it is the belief really

big. Like is is it is the belief really that oh it's so big but if you had 100x more everything would be so different.

Like it would be different for sure but like is the belief that if you just 100x the scale everything would be transformed.

I don't think that's true. So it's back to the age of research again just with big computers.

>> That's a very interesting way to put it.

But let me ask you the question you just posed then. what are we scaling and what

posed then. what are we scaling and what what is what would it mean to have a recipe because I guess I'm not aware of a very clean relationship that almost looks like a

law of physics which existed in pre-training that was a power law between data or computer parameters and loss what is the kind of relationship we

should be seeking and how how should we think about what this new recipe might look like >> so we've we've already witnessed a transition from

one type of scaling to a different type of scaling from pre-training to RL.

Now people are scaling RL now based on what people say on Twitter. They spend

more compute on RL than on pre-training at this point because RL can actually consume quite a bit of compute. You

know, you do very very long rollouts.

>> Yes. So it takes a lot of compute to produce those rollouts and then you get relatively small amount of learning per rollout. So you really can spend you

rollout. So you really can spend you really can spend a lot of compute and I could imagine like I wouldn't at this at this st it's it's more like I wouldn't

even call it a scale um scaling I would say hey like what are you doing and is the thing you are doing the the the the most productive thing you could be doing? Yeah.

doing? Yeah.

>> Can you find a most more productive way of using your compute? We've discussed

the value function business earlier and maybe once people get good at value functions they will be using their their um resources more productively

and if you find a whole other way of training models you could say is this scaling or is it just using your resources I think it becomes a little bit ambiguous in a sense that when

people were in the age of research back then it was like people say hey let's try this and this and this let's try that and that and that oh look something interesting is happening and I think there will be a return to that.

>> So if we're back in the era of research, stepping back, what is the part of the recipe that we need to think most about?

When you say value function, people are already trying the current recipe, but then having LLM as a judge and so forth.

You can say that's a value function, but it sounds like you have something much more fundamental in mind. Do we need do we need to go back to should we even rethink pre-training at all and not just add more steps to the end of that

process?

>> Yeah. So the the the the discussion about value function I think it was interesting. I want to like emphasize

interesting. I want to like emphasize that I think the value function is something like it's going to make RL more efficient and I think that makes a difference but

I think that anything you can do with a value function you can do without just more slowly.

>> Mhm.

>> The thing which I think is the most fundamental is that these models somehow just generalize dramatically worse than people.

>> Yes.

>> And it's super obvious.

That's that seems like a very fundamental thing.

>> Okay, so this is the crux to generalization and there's two sub questions.

There's one which is about sample efficiency which is why should it take so much more data for these models to learn than humans. There's a second about even separate from the amount of data it takes. There's a question of why

is it so hard to teach the thing we want to a model than to a human which is to say for to a human we don't necessarily need a verifiable reward to be able to

you're probably mentoring a bunch of researchers right now and you're you know talking with them you're showing them your code and you're showing them how you think and from that they're picking up your way of thinking and how they should do research. You don't have

to set like a verifiable reward for them that's like okay this is the next part of the curriculum and now this is the next part of your curriculum and oh it was this training was unstable and we gota there's not this shley bespoke

process. So perhaps these two issues are

process. So perhaps these two issues are actually related in some way but I'd be curious to explore this this second thing which feels more like continual learning and

this first thing which feels just like um sample efficiency.

>> Yeah. So you know you could actually wonder one one possible explanation for the human sample efficiency that needs

to be considered is evolution and evolution has given us a small amount of the mo the most useful information possible

and for things like vision hearing and locomotion I think there's a pretty strong case that evolution actually has given us a lot. Mhm.

lot. Mhm.

>> So for example, human dexterity far exceeds I mean robots can become dexterous too if you subject them to like a huge amount of training and simulation. But to train a robot in the

simulation. But to train a robot in the real world to quickly like pick up a new skill like a person does seems very out of reach. And here you could say, oh

of reach. And here you could say, oh yeah, like locomotion, all our ancestors needed great locomotion, squirrels like so locomotion

maybe like we've got like some unbelievable prior. You could make the

unbelievable prior. You could make the same case for vision. You know, I I believe Yan Lan made the point, oh like um children learn to drive after 16 hour

after like 10 hours of practice, which is true, but our vision is so good. At

least for me, when I remember myself being five year old, my I was I was very excited about cars back then. And I'm

pretty sure my car recognition was more than adequate for self-driving already as a 5-year-old.

>> You don't get to see that much data as a 5-year-old. You spend most of your time

5-year-old. You spend most of your time in your parents house, >> so you have very low data diversity, but you could say maybe that's evolution, too.

>> But in language and math and coding, probably not.

>> It still seems better than models. I

mean obviously models are better than the average human at language and math and coding but are they better at the average human at learning?

>> Oh yeah. Oh yeah. Absolutely. What I

meant to say is that language, math and coding and especially math and coding suggests that whatever it is that makes people good at learning

is probably not so much a complicated prior but something more some fundamental thing.

>> Wait, I'm not sure I understood. Why

should that be the case? So consider a skill that people exhibit some kind of great reliability or you know um

>> if the skill is one that was very useful to our ancestors for many millions of years, hundreds of millions of years, you could say you could argue that maybe

humans are good at it because of evolution because we have a prior >> an evolutionary prior that's encoded in some very nonobvious way.

>> Yeah.

>> That somehow makes us so good at it.

>> Yeah.

>> But if people exhibit great ability, reliability, robustness, ability to learn in a domain that really did not

exist until recently, then this is more an indication that people might have just better machine learning period.

>> Mhm. But then how should we think about what that is? Is it a matter of Yeah. What is the ML analogy for what?

Yeah. What is the ML analogy for what?

There's a couple interesting things about it. It takes fewer samples. It's

about it. It takes fewer samples. It's

more unsupervised. You don't have to set a ver like a child learning to drive a car. Children are not learning to drive

car. Children are not learning to drive a car. A teenager learning how to drive

a car. A teenager learning how to drive a car is like not exactly getting some pre-built verifiable reward. there

it comes from their interaction with the machine and the with the environment. Um

and yet it takes much fewer samples. It

seems more unsupervised. It seems more robust. Much more robust. The robustness

robust. Much more robust. The robustness

of people is really staggering.

>> Yeah. So is it like Okay. And do you have a unified way of thinking about why are all these things happening at once?

What is the ML analogy that would that could be could realize something like this? So, so, so, um, this is where, you

this? So, so, so, um, this is where, you know, one of the things that you've been asking about is how can, you know, the teenage driver kind of self-correct and learn from their experience without an

external teacher.

>> And the answer is well, they have their value function, >> right? They have a general sense which

>> right? They have a general sense which is also by the way extremely robust in people like whatever it is the human value function whatever the human value function is

with a few exceptions around addiction it's actually very very robust and so for something like a teenager that's learning to drive they start to

drive and they already have a sense of how they're driving immediately how badly they're unconfident and then they see okay and they and then of course the the learning speed of any teenager is so

fast after 10 hours you're good to go.

>> Yeah, it seems like humans have some solution but I'm curious about like well how are they doing it and like why is it so hard to like how do we need to reconceptualize the way we're training models to make something like this

possible? You know that is a great

possible? You know that is a great question to ask and it's a question I have a lot of opinions about

but unfortunately we live in a world where not not all machine learning ideas are discussed freely and this is this is one of them.

So there's probably a way to do it.

I think it can be done. The fact that people are like that I think it's a proof that it can be done. There may be another blocker though which is there is

a possibility that the human neurons actually do more compute than we think. And if that is true and if that plays an important role

then things might be more difficult. But

regardless I do think it points to the existence of some machine learning principle that I have opinions on. But

unfortunately, circumstances make it hard to to discuss in detail. Even

though >> nobody nobody listens to this podcast, Ilia.

>> Yeah.

>> So, I have to say that prepping for Ilia was pretty tough because neither I nor anybody else had any idea what he's working on and what SSI is trying to do.

I had no basis to come up with my questions and the only thing I could go off honestly was trying to think from first principles about what are the bottlenecks to hi because clearly Ilia

is working on them in some way. Part of

this question involved thinking about RL scaling because everybody's asking how well RL will generalize and how we can make it generalize better. As part of this, I was reading this paper that came out recently on RL scaling and it showed

that actually the learning curve on RL looks like a sigmoid. I found this very curious. Why should it be a sigmoid

curious. Why should it be a sigmoid where it learns very little for a long time and then it quickly learns a lot and then it asmmptotes? This is very different from the power law you see in pre-training where the model learns a

bunch at the very beginning and then less and less over time. And it actually reminded me of a note that I had written down after I had a conversation with a researcher friend where he pointed out that the number of samples that you need

to take in order to find a correct answer scales exponentially with how different your current probability distribution is from the target probability distribution. And I was

probability distribution. And I was thinking about how these two ideas are related. I had this vague idea that they

related. I had this vague idea that they should be connected, but I really didn't know how. I don't have a math

know how. I don't have a math background, so I couldn't really formalize it. But I wondered if Gemini 3

formalize it. But I wondered if Gemini 3 could help me out here. And so I took a picture of my notebook and I took the paper and I put them both in the context of Gemini 3 and I asked it to find the

connection. And it thought a bunch and

connection. And it thought a bunch and then it realized that the correct way to model the information you gain from a single yes or no outcome in RL is as the

entropy of a random binary variable. It

made a graph which showed how the bits you gain for a sample in RL versus supervised learning scale as a pass rate increases. And as soon as I saw the

increases. And as soon as I saw the graph that Gemini 3 made, immediately a ton of things started making sense to me. Then I wanted to see if there was

me. Then I wanted to see if there was any empirical basis to this theory. So I

asked Gemini to code on my experiment to show whether the improvement in loss scales in this way with pass rate. I

just took the code that Gemini outputed.

I copy pasted it into a Google Collab notebook and I was able to run this toy ML experiment and visualize its results without a single bug. It's interesting

because the results look similar but not identical to what we should have expected. And so I downloaded this chart

expected. And so I downloaded this chart and I put it into Gemini and I asked it what is going on here and I came up with a hypothesis that I think is actually correct which is that we're capping how much supervised learning can improve in

the beginning by having a fixed learning rate and in fact we should decrease the learning rate over time. It actually

gives us an intuitive understanding for why in practice we have learning rate schedulers that decrease the learning rate over time. I did this entire flow from coming up with this vague initial

question to building a theoretical understanding to running some toy ML experiments all with Gemini 3. This

feels like the first model where it can actually come up with new connections that I wouldn't have anticipated. It's

actually now become the default place I go to when I want to brainstorm new ways to think about a problem. If you want to read more about RL scaling, you can check out the blog post that I wrote with a little help from Gemini 3. And if

you want to check out Gemini 3 yourself, go to gemini.google.

I am curious if you say we are back in an era of research.

You were there from 2012 to 2020.

And do do you have Yeah. What what is now the vibe going to be if we go back to the era of research? For example,

even after Alexet, the amount of compute that was used to run experiments kept increasing and the size of frontier systems kept increasing.

And do you think now that this era of research will still require tremendous amounts of compute? Um, do you think it will require going back into the

archives and reading old papers? What is

maybe what was the vibe of like you were at Google and um OpenAI and Stanford these places when there was like a more of a vibe of research. What what kind of thing should we be expecting in the

community?

>> So one consequence of um the age of scaling is that there was this um scaling sucked out all the air in the room.

>> Yeah.

And so because scaling sucked out all the air in the room, everyone started to do the same thing.

We got to the point where uh we are in a world where there are more companies than ideas by quite a bit >> actually on that you know there is this

Silicon Valley saying that says that ideas are cheap, execution is everything and people say that a lot.

>> Yeah. And there is truth to that. But

then I saw I saw someone say on Twitter um something like if ideas are are so cheap, how come no one's having any ideas?

>> And I think it's true too. I think like if you think about um research progress in terms of bottlenecks, there are several bottlenecks. If you go

back to the if if and um one of them is ideas and one of them is your ability to bring them to life.

>> Yeah. which might be compute but also engineering.

So if you go back to the '9s let's say you had people who had pretty good ideas and if they had much larger computers maybe they could demonstrate that their ideas were viable but they could not. So

they could only have very very small demonstration that did not convince anyone.

>> Yeah.

>> So the bottleneck was compute. Then in

the age of scaling computers increased a lot. And of course there is a question

lot. And of course there is a question of how much comput is needed but compute is large. So compute is large enough

is large. So compute is large enough such that it's like not obvious that you need that

much more compute to prove some idea like I'll give you an analogy. Alexet

was built on two GPUs. That was the total amount of comput use for it. The

transformer was built on 8 to 64 GPUs. No single

transformer paper experiment used more than 64 GPUs of 2017, which would be like what two GPUs of today. So the

ResNet, right? Many like even even the the um

right? Many like even even the the um you could argue that the like 01 reasoning was not the most compute thing

in the world. So there definitely for for research you need like definitely some amount of compute but it's far from obvious that

you need the absolutely largest amount of compute ever for research. M

>> you might argue and I think it is true that if you want to build the absolutely best system, if you want to build the absolutely best system, then it helps to

have much more compute and especially if everyone is within the same paradigm, then compute becomes one of the big differentiators.

>> Yeah, I guess while it was possible to develop these ideas, I'm asking you for the history because you were actually there. I'm not sure what actually

there. I'm not sure what actually happened, but it sounds like it was possible to develop these ideas using minimal amounts of compute, but it wasn't the transformer didn't immediately become famous. It became the

thing everybody started doing and then started experimenting on top of and building on top of because it was validated at higher and higher levels of compute.

>> Correct. And if you at SSI have 50 different ideas, how will you know which one is the next transformer and which

one is you know brittle without having the kinds of compute that other frontier labs have. So I can I can comment on

labs have. So I can I can comment on that which is the short comment is that you know you

mentioned SSI specifically for us the amount of compute that SSI has for research is really not that small and I

want to explain why like a simple math can explain why the amount of compute that we have is actually a lot more comparable for research than one might

think I'll explain. Okay. So,

SSI has raised $3 billion, which is like not small by it's like a lot by any absolute sense, but you could say, but look at the other companies raising much more,

but a lot of what they're a lot of their compute goes for inference.

Like these big numbers, these big loans, it's earmarked for inference. That's

number one. Number two, you need if you want to have a product on which you do inference, you need to have a big staff of engineers of salespeople. A lot of

the research needs to be dedicated for producing all kinds of product related features. So then when you look at

features. So then when you look at what's actually left for research, the difference becomes a lot smaller.

Now the other thing is is that if you are doing something different, do you really need the absolute maximum scale to prove it? I don't think it's true at

all. I think that in our case, we have

all. I think that in our case, we have sufficient compute to prove to convince ourselves and anyone else that what we're doing is correct.

There's been public estimates that you know companies like OpenAI spend on the order of56 billion dollars a year even just so far on experiments.

>> This is separate from the amount of money they're spending on inference and so forth. So seems like they're spending

so forth. So seems like they're spending more a year running exper like research experiments than you guys have in total funding.

>> I think it's a question of what you do with it. It's a question of what you do

with it. It's a question of what you do with it. like they have a like is the

with it. like they have a like is the more I think in in in their case in the case of others I think there's a lot more demand on the training compute there's a lot more different work

streams there is there are different modalities there is just more stuff and so it becomes fragmented >> how will SSI make money >> you know

my answer to this question is something like we just f right now we just focus on the research and then the answer to that question will reveal itself. I think

there will be lots of possible answers.

>> Is SSI's plan still to straightshot super intelligence?

>> Maybe.

I think that there is merit to it.

>> I think there's a lot of merit because I think that it's very nice to not be affected by the day-to-day market competition.

But I think there are two reasons that may cause us to change the plan. one is

pragmatic if timelines turn out to be long which they might and second I think

there is a lot of value in the best and most powerful AI being out there impacting the world >> I think this is a meaningfully valuable thing

>> but then so why is your default plan to straightshot super intelligence because it sounds like you know openai anthropic all these other companies they're explicit thinking is look we have weaker

and weaker intelligences that the public can get used to and prepare for and why is it potentially better to build a super intelligence directly.

>> So I'll make the case for and against.

>> Yeah.

>> The case for is that you are so one of the challenges that people face when they're in the market is that they have to participate

in the rat race. And the rat race is quite difficult in that it exposes you to to to difficult trade-offs which you need to make.

And there is it is it is nice to say we'll insulate ourselves from all this and just focus on the research and come out only when we are ready and not before.

But the counterpoint is valid too. And

those those are opposing forces. The

counterpoint is, hey, it is useful for the world to see powerful AI. It is

useful for the world to see powerful AI because that's the only way you can communicate it.

>> Well, I guess not even just that you can communicate the idea, but >> communicate the AI, not the idea.

Communicate the AI.

>> What do you mean communicate the AI?

>> So, okay. So, let's suppose you read an essay about AI >> and the essay says AI is going to be this and AI is going to be that and it's going to be this. and you read it and you say okay this is an interesting essay

>> right >> now suppose you see an AI doing this an AI doing that it is incomparable like basically I think I think that there is

a big benefit from AI being in the public and that would be a reason for us to not be quite straight shot >> yeah well I guess it's not even that

which I but I do think that is an important part of it the other big thing is I can't think of another discipline in human engineering and research where

the end artifact was made safer mostly through just thinking about how to make it safe as opposed to why are airplane crashes per mile so much lower today than they were decades ago? Why is it so

much harder to find a bug in Linux than it would have been decades ago? And I

think it's mostly because these systems were deployed to the world. You noticed

failures. those failures were corrected and the systems became more robust. Now,

I'm not sure why AGI and superhuman intelligence would be any different, especially given, and I hope we can talk, we're going to get to this.

It seems like the harms of super intelligence are not just about like having some malevolent uh paper clipper out there, but it just like this is a really powerful thing and we don't even know how to conceptualize how people

interact with it, what people will do with it and having gradual access to it seems like a um better way to maybe spread out the impact of it and to help

people prepare for it. Well, I think I think on this point even in the straight shot scenario, you would still do a gradual release of it is how I would

imagine it.

The the gra gradualism would be an inherent inherent component of any plan.

It's just a question of what is the first thing that you get out of the door. That's number one. Number two, I

door. That's number one. Number two, I also think you know I believe you have advocated for continual learning more than other people >> and I actually think that this is an

important and correct thing and here is why so one of the things so I'll give you another example of how thinking how

language affects thinking and in this case it will be two words two words that have shaped everyone's thinking I maintain

F first word AGI second word pre-training let me explain so the word the term AGI

why does this term exist it's a very particular term why does it exist there's a reason the reason that the term AGI exists is in my opinion not so

much because it's like a very important essential descriptor of in of of some end state of intelligence But

because it is a reaction to a different term that existed and the term is narrow AI. If you go back to ancient history of

AI. If you go back to ancient history of gameplay AI of checkers AI, chess AI, computer games AI, everyone would say look at this narrow intelligence. Sure

the chess AI can beat Casper off but it can't do anything else. It is so narrow artificial narrow intelligence. So in

response, as a reaction to this, some people said, "Well, this is not good. It

is so narrow. What we need is general AI."

AI." General AI, an AI that can just do all the things.

The second and and that term just got a lot of traction.

>> Yeah.

>> The second thing that got a lot of traction is pre-training.

Specifically, the recipe of pre-training. I think the current the

pre-training. I think the current the way people do RL now is maybe um un is undoing the conceptual imprint of pre-training but pre-training had the

property you do more pre-training and the model gets better at everything more or less uniformly >> general AI pre-training gives AGI

but the thing that happened with AGI and pre-training is that in some sense they overshot the target because by the kind if you think about

the term AGI you will realize and especially in the context of pre-training you will realize that a human being is not an AGI

because a human being yes there is definitely a foundation of skills a human being a human being lacks a huge amount of

knowledge instead we rely on continual learning We rely on continual learning. And so

then when you think about okay so let's suppose that we achieve success and we produce a safe super some kind of safe super intelligence. The question is but

super intelligence. The question is but how do you define it? Where on the curve of continual learning is it going to be I produce like um a super intelligent 15year-old that's very eager to go and

you say okay I'm going to they don't know very much at all the great student very eager. You go and be a programmer.

very eager. You go and be a programmer.

You go and be a doctor.

Go and learn. So you could imagine that the deployment itself will involve some kind of a learning trial and error period. It's a process as opposed to you

period. It's a process as opposed to you drop the finished thing.

>> Okay. I I I I see. So you're you're suggesting that the thing you're pointing out with super intelligence is not some finished

mind which knows how to do every single job in the economy because the way say the original I think open charter or whatever defines AGI is like it can do every single job that a every single

thing a human can do. You're proposing

instead a mind which can learn to do any single every single job.

>> Yes. And that is super intelligence. And

then but once you have the learning algorithm, it gets deployed into the world the same way a human laborer might join an organization.

>> And it seems like one of these two things might happen. Maybe neither of these happens. one, this super efficient

these happens. one, this super efficient learning algorithm becomes superhuman, becomes as good as

you and potentially even better at the task of ML research and as a result the algorithm itself becomes more and more superhuman. The other is even if that

superhuman. The other is even if that doesn't happen. If you have a single

doesn't happen. If you have a single model, I mean this is explicit your vision. If you have a single model where

vision. If you have a single model where instances of a model which are deployed through the economy doing different jobs, learning how to do those jobs, continually learning on the job, picking up all the skills that any human could

pick up but actually picking them all up at the same time and then amalgamating the learnings.

you basically have a model which functionally becomes super intelligent even without any sort of recursive self-improvement in software right because you now have one model that can

do every single job in the economy and humans can't merge our minds in the same way and so do you expect some sort of like intelligence explosion from broad deployment

>> I think that it is likely that we will have rapid economic growth I think the broad deployment And

like there are two arguments you could make which are conflicting.

One is that look if indeed you get once indeed you get to a point where you have an AI that can learn to do

things quickly and you have many of them then they will then there will be a strong force to deploy them in the economy. Unless there will be some kind

economy. Unless there will be some kind of a regulation that stops it, which by the way there might be. But I think the idea of very rapid economic growth for

some time, I think it's very possible from broad deployment. The other

question is how rapid it's going to be.

So I think this is hard to know because on the one hand you have this very efficient worker. on the other hand

efficient worker. on the other hand there is the world is just really big and there's a lot of stuff and that stuff moves at a different speed but then on the other hand now the

AI could you know so I think very rapid economic growth is possible and we will see like all kinds of things like different countries with different rules and the ones which have the friendlier

rules the economic growth will be faster hard to predict >> some people in our audience like to read the transcripts instead of listening to the episode and so we put a ton of effort into making the transcripts read

like they are standalone essays. The

problem is that if you just transcribe a conversation verbatim using a speech to text model, it'll be full of all kinds of fits and starts and confusing phrasing. We mentioned this problem to

phrasing. We mentioned this problem to Labelbox and they asked if they could take a stab. Working with them on this is probably the reason that I'm most excited to recommend Label Box to people. It wasn't just, oh, hey, tell us

people. It wasn't just, oh, hey, tell us what kind of data you need and we'll go get it. They walked us through the

get it. They walked us through the entire process from helping us identify what kind of data we needed in the first place to assembling a team of expert aligners to generate it. Even after we

got all the data back, Labelbox stayed involved. They helped us choose the

involved. They helped us choose the right base model and set up auto QA on the model's output so that we could tweak and refine it. And now we have a new transcriber tool that we can use for

all our episodes moving forward. This is

just one example of how Labelbox meets their customers at the ideas level and partners with them through their entire journey. If you want to learn more or if

journey. If you want to learn more or if you want to try out the transcriber tool yourself, go to labelbox.com/barcash.

It seems to me that this is a very precarious situation to be in where look in the limit we know that this should be possible because if you have

something that is as good as a human at learning but which can merge its brains merge there are different instances in a way that humans can't merge already.

This seems like a thing that should physically be possible. Humans are

possible. Digital computers are possible. You just need both of those

possible. You just need both of those combined to produce this thing. And it

also seems like this kind of thing is extremely um powerful and economic grow growth is one way to put it. Um I mean Dyson spear is a lot

put it. Um I mean Dyson spear is a lot of economic growth but another way to put it is just like you will have potentially a very short period of time because a human on the job can you know you you're hiring people at SSI in six months they're like net productive

probably right um a human like learns really fast and so this thing is becoming smarter and smarter very fast.

What is how do you think about making that go well and why is SSI positioned to do that well? What is SSI's plan there basically is what I'm trying to ask.

>> Yeah.

So one of the one of the ways in which my thinking has been changing is that

I now place more importance on AI being deployed incrementally and in advance. One very

difficult thing about AI is that we are talking about systems that don't yet exist.

And it's hard to imagine them.

I think that one of the things that's happening is that in practice it's very hard to feel the AGI.

It's very hard to feel the AGI.

We can talk about it, but it's like it's like talking about like the long f like imagine like having a conversation about like how is it like to be old when

you're like old and and frail and you can have a conversation. and you can try to imagine it, but it's just hard and you come back to reality where that's not the case. And I

think that a lot of the issues around AGI and its future power stem from the

fact that it's very difficult to imagine future AI is going to be diff different.

It's going to be powerful. Indeed, the

whole problem, what is the problem of AI and AGI? The whole problem is the power.

and AGI? The whole problem is the power.

The whole problem is the power.

When the power is really big, what's going to happen?

And one of the one of the ways in which I've changed my mind over the past year and so that that change of mind may back may I'll say I I'll I'll hedge a little

bit may back propagate into into the plans of our of our company is that so if it's hard to imagine

what do you do you got to be showing the thing you got to be showing the thing and I maintain that I think I think most People who work on AI also can't imagine

it because it's too different from what people see on a day-to-day basis.

I do maintain here is something which I predict will happen. That's a

prediction.

I maintain that as AI becomes more powerful then people will change their behaviors

and we will see all kinds of unprecedented things which are not happening right now and I'll give some examples. I do like I I think I think

examples. I do like I I think I think for better or worse the the frontier companies will play a very important role in what happens as will the government and the kind of things that I

think we'll see which you see the beginnings of companies that are fierce competitors starting collaborate to to collaborate

on AI safety you may have seen open AI and anthropic doing a first small step but that did not exist That's actually something which I predicted in one of my talks

about three years ago that such a thing will happen. I also maintain that as AI

will happen. I also maintain that as AI continues to become more powerful, more visibly powerful, there will also be a desire from governments and the public

to do something and I think that this is a very important force of showing the AI. That's number one.

Number two, okay, so then the AI is being built. what needs to what needs to

being built. what needs to what needs to be done.

So one thing that I maintain that will happen is that right now people who are working on AI I maintain that the AI doesn't feel powerful because of its mistakes.

I do think that at some point the AI will start to feel powerful actually and I think when that happens we will see a big change in the way

all AI companies approach safety.

they'll become much more paranoid. I

think I I say this as a predict as a as a as a prediction that we will see happen. We'll see if I'm right, but I

happen. We'll see if I'm right, but I think this is something that will happen because they will see the AI becoming more powerful. Everything that's

more powerful. Everything that's happening right now, I maintain is because people look at today's AI and it's hard to imagine the future AI.

And there is a third thing which needs to happen. And I think this is this this

to happen. And I think this is this this and I'm talking about it in in broader terms not just from the perspective of SSI because you ask me about our company but the question is okay so then what

should what should the companies aspire to build? Yeah.

to build? Yeah.

>> What should they aspire to build? And

there has been one big idea that actually every that everyone has been locked in locked into which is the the self-improving AI.

And why why did it happen? Because there

is fewer ideas than companies. But I

maintain that there is something that's better to build. And I think that everyone will actually want that. It's

like the AI that's robustly aligned to care about sentient life specifically.

I think in particular it will be there's a case to be made that it will be easier to build an AI that cares about sentient life than an AI that cares about human

life alone because the AI itself will be sentient.

And if you think about things like mirror neurons and human empathy for animals, which is, you know, you might argue it's not big enough, but it exists. I think it's an emerging

exists. I think it's an emerging property from the fact that we model others with the same circuit that we used to model ourselves because that's the most efficient thing to do.

So, even if you got an AI to care about sentient beings, and it's not actually clear to me that that's what you should try to do if you solved alignment, it would still be the case that most

sentient beings will be AIS. There will

be trillions, eventually quadrillions of AI. Humans will be a very small fraction

AI. Humans will be a very small fraction of sentient beings.

So, it's not clear to me if the goal is some kind of human control over this future civilization

that this is the best criterion.

>> It's true. I I think that it's possible it's not the best criterion. I'll say two things. I think

criterion. I'll say two things. I think

that thing number one I think that if there so I think that care for sentient life I think there is merit to it. I think it

should be considered. I think that it will be helpful if there was some kind of a short list of ideas that then the

companies when they are in the situation could use. That's number two. Number

could use. That's number two. Number

three, I think it would be really materially helpful if the power of the most powerful super intelligence was somehow capped because it would address a lot of these

concerns.

The question of how to do it, I'm not sure, but I think that would be materially helpful when you're talking about really really powerful systems. >> Yeah. Um, before we continue the 11

>> Yeah. Um, before we continue the 11 discussion, I I want to double click on that. How much room is there at the top?

that. How much room is there at the top?

How do you think about super intelligence? Do you think I mean using

intelligence? Do you think I mean using this learning efficiency idea maybe is just extremely fast at learning new skills or new knowledge and does it just have a bigger pool of strategies? Is

there a single cohesive it in the center that's more powerful or bigger? And if

so, do you do you imagine that this will be sort of godlike in comparison to the rest of human civilization? or does it just feel like another agent or another cluster of agents?

>> So this is an area where different people have different intuitions.

>> I think it will be very powerful for sure. I think that what I think is most

sure. I think that what I think is most likely to happen is that there will be multiple such AIs being created roughly at the

same time.

I think that if the cluster is big enough, like if the cluster is literally continent sized, that thing could be really

powerful indeed, right? If you literally have a continentsized cluster, like those those AIs can be very powerful.

And I like all I can tell you is that if you're talking about extremely powerful AIs, like truly dramatically powerful, then yeah, it would be nice if they

could be restrained in some ways or if there was some kind of an agreement or something because I think that if you are saying

hey like if if you really like what what is the the concern of super intelligence? What is one way to explain

intelligence? What is one way to explain the concern? If you imagine a system

the concern? If you imagine a system that is sufficiently powerful, like really sufficiently powerful, and you could say, okay, you need to do something sensible like care for

sentient life, let's say, in a very single-minded way, we might not like the results. That's really what it is. And

results. That's really what it is. And

so maybe, by the way, the answer is that you do not build a single you do not build an RL agent in the usual sense.

And actually, I'll point I'll point several things out. I think human beings are a semi-religent.

You know, we pursue a reward and then the emotions or whatever make us tire out of the reward. We pursue a different reward.

The market is like kind it's like a very shortsighted kind of agent. Evolution is

the same. Evolution is very intelligent in some ways but very dumb in other ways. The government has been designed

ways. The government has been designed to be a never- ending fight between three parts which has an effect. So I

think things like this another thing that makes this discussion difficult is that we are talking about systems that don't exist that we don't know how to build right that's the other thing and that's

actually my belief I think what people are doing right now will go some distance and then peter out it will continue to improve but it will also not be it so the it we don't know how to

build and I think that a lot h a lot hinges on understanding in reliable generalization

and I'll say another thing which is like you know one of the things that you could say is that cause alignment to be difficult is that human val that it's it's um

your ability to learn human values is fragile then your ability to optimize them is fragile will you actually learn to optimize them and then can't you say are these not all instances of

unreliable generalization why is it that human beings appear to generalize so much better. What if

generalization was much better? What

would happen in this case? What would be the effect? But those we can't we can't

the effect? But those we can't we can't like those questions are right now still unanswerable.

>> Um how does one think about what AI going well looks like because I think you scoped out how AI might evolve.

We'll have these sort of continual learning agents. AI will be very

learning agents. AI will be very powerful. Maybe there will be many

powerful. Maybe there will be many different AIs. How do you think about

different AIs. How do you think about lots of continent computes size intelligences going around? How

dangerous is that? How do we make that less dangerous? And how do we do that in

less dangerous? And how do we do that in a way that protects a equilibrium where there might be misaligned AIs out there and bad

actors out there? So, one reason why I liked the AI that cares for sentient life, >> you know, and we can debate on whether it's good or bad, but

if the first N of these dramatic systems actually do care for, you know, love humanity or something, you know, care for sentient life. Obviously, this

also needs to be achieved. This needs to be achieved.

So if this is achieved by the first end of those systems then then I can see it go well at least for quite some time and then there is

the question of what happens in the long run what happens in the long run how do you achieve a long run equilibrium >> and I think that there there is an

answer as well and I don't like this answer but it needs to be considered In the long run, you might say, okay, so if you have a world where powerful AI

exist. In the short run, you could say,

exist. In the short run, you could say, okay, you have universal high income.

You have universal high income and we all doing well. But we know that what do the Buddhists say? Change is the only constant. And so things change and there

constant. And so things change and there is some kind of government political structure thing and it changes because these things have a shelf life. you know

some new new government thing comes up and it functions and then after some time it stops functioning that's something that you see happening all the time and so I think that for the

long run equilibrium one approach you could say okay so maybe every person will have an AI that will do their bidding and that's good and if

that could be maintained indefinitely that's true but the downside with that is okay so then the AI goes and like earns earn earn you know earns money for

for the person and you know advocates for their needs in like the political sphere and maybe then writes a little report saying okay here's what I've done here's the situation and the person says

great keep it up but the person is no longer a participant and then you can say that's a precarious place to be in but so I'm going to

preface by saying I don't like this solution but it is a solution And the solution is if people become

part AI with some kind of neural link++ because what will happen as a result is that now the AI understands something and we understand it too like because now the understanding is

transmitted wholesale. So now if the AI

transmitted wholesale. So now if the AI is in some situation now it's like you are involved in the situation yourself fully and I think this is the answer to the

equilibrium. I wonder if uh the fact

equilibrium. I wonder if uh the fact that emotions which were developed millions or in many cases billions of years ago in a totally different

environment are still guiding our actions so strongly is an example of alignment success to maybe spell out

what I mean the brain stem has these I don't know if it's more accurate to call it a value function or reward function but the brain stem as a directive where it's saying mate with somebody who's more successful. The

cortex is the part that understands what does success mean in the modern context.

But the brain stem is able to align the cortex and say however you recognize success to be and I I'm not smart enough to understand what that is. You're still

going to pursue this directive.

>> I think I think there is so I think there's a more general point.

M >> I think it's actually really mysterious how the brain encodes high level desires. Sorry, how evolution encodes

desires. Sorry, how evolution encodes high level desires.

>> Like it's pretty easy to understand how evolution would would endow us with the desire for food that smells good cuz smell is a chemical and so just pursue that chemical. It's

very easy to imagine such a me evolution doing such a thing. But evolution also has has endowed us with all these social desires like we we really care about

being seen positively by society. We

care about being in a good standing. We

like all these social intuitions that we have. I feel strongly that they are

have. I feel strongly that they are baked in. And I don't know how evolution

baked in. And I don't know how evolution did it because it's a high level concept. It's represented in the brain.

concept. It's represented in the brain.

like what people think like let's say you are like you care about some social thing it's not like a low-level signal like

smell it's not something that for which there's a sensor like the brain needs to do a lot of processing to piece together lots of bits of information to understand what's going on socially and

somehow evolution said that's what you should care about >> yes >> how did it do it and it did it quickly too >> because I think all these sophisticated social things that um we care about. I

think they evolved pretty recently.

>> So, evolution had an easy time hardcoding this high level desire and I maintain or you know at least I'll say I'm unaware of good hypothesis for how

it's done. I I had some ideas I was

it's done. I I had some ideas I was kicking around but none of them none of them u are satisfying.

>> Yeah. And what's especially impressive is if it was a desire that you learned in your lifetime, it kind of makes sense because your brain is intelligent. It

makes sense why we be able to learn intelligent desires. But your point is

intelligent desires. But your point is that the desire is maybe this is not your point, but one way to understand it is the desire is built into the genome and the genome is not intelligent,

right? But it's able to you're somehow

right? But it's able to you're somehow able to describe this feature that requires like it's not even clear how you define that feature and you can get it into the you can build it into the genes. Yeah, essentially, or maybe I'll

genes. Yeah, essentially, or maybe I'll put it differently. If you think about the tools that are available to the genome, it says, "Okay, here's a recipe for building a brain." And you could say,

"Here is a recipe for connecting the dopamine neurons to like the smell sensor."

sensor." >> Yeah.

>> And if the smell is a certain kind of, you know, good smell, you want to eat that. I could imagine the genome doing

that. I could imagine the genome doing that. I'm I'm claiming that it is harder

that. I'm I'm claiming that it is harder to imagine. It's harder to imagine the

to imagine. It's harder to imagine the genome saying you should care about some complicated computation that your entire brain that like a big chunk of your

brain does. That's all I'm claiming. I I

brain does. That's all I'm claiming. I I

can tell you like a speculation. I was

wondering how it could be done and let me offer a speculation and I'll explain why the speculation is probably false.

So the speculation is okay. So the brain it's like the brain has those regions.

You know the brain regions. We have our cortex right?

>> Yeah.

>> It has all those brain regions and the cortex is uniform. But the brain regions and and and the neurons in the cortex, they kind of speak to their neighbors mostly. And that's explains why you get

mostly. And that's explains why you get brain regions because if you want to do some kind of speech processing, all the neurons that do speech need to talk to each other and they can and because neurons can only speak to their nearby

neighbors for the most part, it has to be a region. All the regions are mostly located in the same place from person to person. So maybe evolution hardcoded

person. So maybe evolution hardcoded literally a location on the brain.

So it says, "Oh, like when when like you know the GPS of the brain, GPS coordinates such and such when that fires, that's what you should care about." Like maybe that's what evolution

about." Like maybe that's what evolution did cuz that would be within the toolkit of evolution. Yeah. Although there are

of evolution. Yeah. Although there are examples where for example people who are born blind have that area of their cortex adopted by

another sense and I have no idea but I'd be surprised if the desires or the reward functions which require visual

signal no longer worked. You know people who have their different areas of their cortex co-opted. For example, if you no

cortex co-opted. For example, if you no longer have vision, can you still feel the sense that I want people around me to like me and so forth, which usually there's also visual cues for.

>> So, I actually fully agree with that. I

I think there's an even stronger counter argument to this theory, >> which is like if you think about people, so there are people who get half of their brain removed in childhood.

>> Yeah. and they still have all their brain regions, but they all somehow move to just one hemisphere, which suggests that the brain regions the the location is not fixed. And so that theory is not

true. It would have been cool if it was

true. It would have been cool if it was true, but it's not. And so I think that's a mystery, but it's an interesting mystery. Like the fact is

interesting mystery. Like the fact is somehow >> evolution was able to endow us to care about social stuff very very reliably.

And even people who have like all kinds of strange mental conditions and deficiencies and emotional problems tend to care about this. Also,

>> AI tools like defakes, voice clones, and agents have dramatically increased the sophistication of fraud and abuse. So,

it's more important than ever to actually understand the identity and intent of whoever or whatever is using your platform. That's exactly what

your platform. That's exactly what Sardine helps you do. studying brings

together thousands of device behavior and identity signals to help you assess risk. Everything from how a user types

risk. Everything from how a user types or moves their mouse or holds their device to whether they're hiding their true location behind a VPN to whether they're injecting a fake camera feed

during KYC selfie checks. Sardine

combines these signals with insights from their network of almost 4 billion devices. things like a user's history of

devices. things like a user's history of fraud or their associations with other high-risisk accounts so you can spot bad actors before they do damage. This would

literally be impossible if you only use data from your own application. Sardine

doesn't stop at detection. They offer a suite of agents to streamline onboarding checks and automate investigations. So,

as fraudsters use AI to scale their attacks, you can use AI to scale your defenses. Go to sardine.ai/warcash.

What is SSI planning on doing differently? So presumably your plan is

differently? So presumably your plan is to be one of the frontier companies when this time arrives and then what is presumably you started SSI because

you're like I I think I have a way of approaching how to do this safely in a way that the other companies don't. What

what is that difference? So the way I would describe it as there are some ideas that I think are promising and I want to investigate them and see if they are indeed promising or

not. It's really that simple. It's an

not. It's really that simple. It's an

attempt. I think that if the ideas turn out to be correct, these ideas that we discussed around understanding generalization. Hm.

generalization. Hm.

>> If these ideas turn out to be correct then I think we will have something worthy. Will they turn out to be

worthy. Will they turn out to be correct? We are doing research. We are

correct? We are doing research. We are

squarely age of research company. We are

making progress. We've actually made quite good progress over the past year but we need to keep making more progress >> more research.

>> And that's how I see it. I see it as an attempt to be an attempt to be a voice and a participant.

Um, people have asked uh your co-founder and previous CEO left to go to Meta recently and people have asked well if there was a lot of

breakthroughs being made that seems like a thing that should have been unlikely.

I wonder how you respond.

>> Yeah. So I in for for this I will simply remind a few facts that may have been forgotten and I think this these facts which provide the context I think they

explain the situation. So the context was that we were fundraising at a 32 billion valuation

and then Meta um came in and offered to to acquire us and I said no but my former co-founder

like in some sense said yes and as a result he also was able to enjoy from a lot of near-term liquidity and he was the only person from SSI to join Meta.

It sounds like SSI's plan is to be a company that is at the frontier when you get to this very important period in human history where you have superhuman intelligence and you have these ideas about how to

make superhuman intelligence go well but other companies will be trying their own ideas. What distinguishes SSI's approach

ideas. What distinguishes SSI's approach to making super intelligence go well.

The >> the main thing that distinguishes SSI is its technical approach.

So we have a different technical approach that I think is worthy and we are pursuing it.

I maintain that in the end there will be a convergence of strategies. So I think there will be a convergence of strategies where at some point as AI becomes more

powerful it's going to become more or less clearer to everyone what the strategy should be. And it should be something

should be. And it should be something like, yeah, you need to find some way to talk to each other. And you want your first

actual like real super intelligent AI to be aligned and somehow be you know care for sentient life, care

for people, democratic, one of those, some combination of thereof. And I think this is the condition

that everyone should strive for and that's what SSI is striving for. And I

think that with time, if not already, all the other companies will realize they're striving towards the same thing.

And we'll see. I think that the world will truly change as AI becomes more powerful.

>> Yeah.

>> And I think a lot of these forecasts will like I think things will be really different and people will be acting really differently. What speaking of

really differently. What speaking of forecasts, what are your forecasts to this system you're describing which can learn as well as a human and subsequently as a result become

superhuman.

>> I think like uh 5 to 20 >> 5 to 20 years.

>> Mhm.

>> So I just want to unroll your how you might see the world coming. It's

like we have a couple more years where these other companies are continuing the current approach and it stalls out and stalls out here meaning they earn no more than low hundreds of billions in revenue or how do you think about what

stalling out means?

>> Yeah, I think the re I think it could I think it could stall out and I think stalling out will look like it will all look very similar.

>> Yeah.

>> Among all the different companies something like this. I'm not sure because I think I think I think even with I think even I think even with stolen out I think these companies could make a stupendous stupendous revenue

maybe not profits because they will be it will be they will need to work hard to differentiate each other from themselves but revenue definitely >> but there's something in your model

implies that the when the correct solution does emerge there will be convergence between all the companies and I'm curious why you think that's the case >> well I was talking more about converg on

their largest strategies.

>> I think eventual convergence on the technical approach is probably going to happen as well, but I I was alluding to convergence to the largest strategies.

What what what exactly is the thing that should be done?

>> I I just want to better understand how you see the future on rolling. So

currently we have these different companies and you expect their approach to continue generating revenue. Yes.

>> But not get to this humanlike learner.

>> Yes.

>> So now we have these different forks of companies. We have you, we have thinking

companies. We have you, we have thinking machines, there's a bunch of other labs.

>> Yes. and maybe one of them figures out the correct approach >> but then the release of their product makes it clear to other people how to do this thing.

>> I think it won't be clear how to do it thing but it will be clear that something different is possible >> right >> and that is information and I think people will will then be trying to

figure out how how that's how that works. I do think though that one of the

works. I do think though that one of the things that's that I think you know not addressed here not discussed is that

with each increase in the AI's capabilities I think there will be some kind of changes but I don't know exactly which ones in how things are being done.

So like I think it's going to be important yet I can't spell out what that is exactly.

>> And how how are the by default you would expect the company that has the model company that has that model to be getting all these gains because they have the model that is learning how to do all has the skills

and knowledge that it's building up in the world. What is the reason to think

the world. What is the reason to think that the benefits of that would be widely distributed and not just end up at whatever model company gets this continuous learning loop going first?

>> Like I think that empirically what happen so here here is what I think is going to happen. Number one, I think empirically when

let's let's let's look at let's look at how things have gone so far with um the AIS of the past. So one company produced an advance and the other company

scrambled and produced some competi some some similar things after some amount of time and they started to compete in the market and push their push the prices

down >> and so I think from the market perspective I think something similar will happen there as well even if someone okay we talking about the good

world by the way where what's the good world. What's the good world?

Where we have these powerful humanlike learners that are also like and by the way maybe there there's another thing we haven't discussed on the on the the spec

of the super intelligent AI that I think is worth considering is that you make it narrow can be useful and narrow at the same time. So you can have lots of narrow

time. So you can have lots of narrow super intelligent AIs. But suppose you have many of them and you have some and you have some company that's producing a lot of um

profits from it and then you have another company that comes in and starts to compete and the way the competition is going to work is through specialization.

I think what's going to happen is that the way competition like competition loves specialization and you see it in the market, you see it in evolution as well.

So you're going to have lots of different niches and you're going to have lots of different companies who are occupying different niches in in this kind of world where you might

say yeah like one AI company is really quite a bit better at some area of really complicated economic activity and a different company is better at another area and the third company is really good at litigation and

>> is this contradicted by what human like learning implies is that like it can learn >> it can but but you have accumulated learning you have a investment. You

spent a lot of compute to become really really really good really phenomenal at this thing and someone else spent a huge amount of comput and a huge amount of experience to get really really good at some other thing >> right

>> you apply a lot of human learning to get there but now like you you are at this high point where someone else would say look like I don't want to start learning what you've learned to do >> I guess that would require many

different companies to begin at the human like continual learning agent at the same time so that they can start their different research in different

branches. But if one company,

branches. But if one company, you know, gets that agent first or gets that learner first, it does then seem like well, you know,

they could like if you just think about every single job in the economy, you just have uh instance learning each one seems tractable for a company.

>> Yeah, that's that's a valid argument. My

my strong intuition is that it's not how it's going to go.

My strong intuition is that yeah like the argument says it will go this way.

>> Yeah.

>> But my strong intuition is that it will not go this way that this is the you know in in theory there is no difference between theory and practice. In practice

there is and I think that's going to be one of those >> a lot of people's models of recursive self-improvement literally explicitly state we will have a million Ilias in a server that are coming up with different

ideas and this will lead to a super intelligence emerging very fast. Do you

have some intuition about how parallelizable the thing you are doing is? How how what are the gains from

is? How how what are the gains from making copies of Ilia? I don't know. I

think I think there'll definitely be a there'll be diminishing returns because you want you want people who think differently rather than the same. I

think that if they were literal copies of me, I'm not sure how much more incremental value you'd get. I think

that but people who think differently that's what you want.

>> Why is it that it's been if you look at different models even released by totally different companies trained on potentially non-over overlapping data sets. It's actually crazy how similar

sets. It's actually crazy how similar LLMs are to each other.

>> Maybe the data sets are not as non-over overlapping as it seems. But there's there's some sense there's like even if an individual human might be less productive than the future AI.

Maybe there's something to the fact that human teams have more diversity than teams of AIs might have. But how do we elicit meaningful diversity among AI? So

I think just raising the temperature just results in gibberish. I think you want something more like >> different scientists have different different prejudices or different ideas.

How do you get that kind of diversity among AI agents? So the reason there has been no diversity I believe is because of pre-training.

All the pre-trained models are the same pretty much because the pre-train on the same data. Now RL and post training is

same data. Now RL and post training is where some differentiation starts to emerge because different people come up with different RL training.

>> Yeah. And then I've heard you hint in the past about selfplay as a way to either get data or match agents to other agents of equivalent intelligence to

kick off learning. How should we think about why there's no public um proposals of this kind of thinking working with LLM?

>> I would say there are two things to say.

I would say that the reason why I thought selfplayful was interesting is because it offered a way to create models using compute only without data,

right? And if you think that data is the

right? And if you think that data is the ultimate bottleneck, then using compute only is very interesting. So that's what makes it interesting. Now the

the thing is that selfplay at least the way it was done in the past when you have agents which are somehow compete with each other it's only good for developing a

certain set of skills it is too narrow.

It's only good for like negotiation uh conflict certain social skills strategizing that kind of stuff. And so

if you care about those skills then selfplay will be useful. Now actually I think that selfplay did find a home but just in a different form

in a different form. So things like debate prove a verifier. You have some kind of an LLM as a judge which is also incentivized to find mistakes in your

work. You could say this is not exactly

work. You could say this is not exactly selfplay but this is you know a related adversarial setup that people are doing.

I believe >> and really selfplay is an example of um is a special case of more general like um competition between between agents, >> right? The response the natural response

>> right? The response the natural response to competition is to try to be different. And so if you were to put

different. And so if you were to put multiple agents and you tell them, you know, you all need to work on some problem and you're an agent and you're inspecting what everyone else is

working, you're going to say, well, if they already taken this approach, it's not clear I should pursue I should pursue something differentiated. And so

I think that something like this could also create an incentive for um a diversity of approaches.

>> Yeah. Um final question, what is research taste? You're obviously

the person in the world who is considered to have the best taste in doing research in AI. you were uh the

co-author on many of the biggest the biggest things that have happened in the history of deep learning from Alex net to GPT3 to so on what is it that how do you characterize how

you come up with these ideas >> I can answer so I can comment on this for myself I think different people do it differently

>> but one thing that um guides me personally is an aesthetic of how AI should be

>> by thinking about how people are but thinking correctly >> like it's very easy to think about how people are incorrectly but what does it mean to think about people correctly

>> so I'll give you some examples the idea of the artificial neuron is directly inspired by the brain and it's a great idea why because you say sure

the brain has all these different organs has the faults but the faults probably don't matter M >> why do we think that the neurons matter?

Because there's many of them.

>> It kind of feels right. So you want the neuron.

>> Yeah, >> you want some kind of local learning rule that will change the connections.

You want some local learning rule rule that will change the connections between the neurons, right? It feels plausible that the brain

right? It feels plausible that the brain does it. The idea of the distributed

does it. The idea of the distributed representation, the idea that the brain, you know, the brain responds to experience or neural network should learn from experience, not response. The

brain learns from experience.

the neural natural level of experience and you kind of ask yourself is some is something fundamental or not fundamental how things should be.

>> Yeah.

>> And I think that's been guiding me a fair bit kind of thinking from multiple angles and looking for almost beauty.

Beauty, simplicity, ugliness. There's no

room for ugliness. It's just beauty, simplicity elegance correct inspiration from the brain. And all of those things need to be present at the same time. And the more they are

same time. And the more they are present, the more confident you can be in a top- down belief. And then the top down belief is the thing that sustains you when the experiments contradict you.

Because if you just trust the data all the time, well, sometimes you can be doing a correct thing, but there's a bug. But you don't know that there is a

bug. But you don't know that there is a bug. How can you tell that there is a

bug. How can you tell that there is a bug?

>> How do you know if you should keep debugging or you conclude it's the wrong direction? Well, it's the top down.

direction? Well, it's the top down.

Well, how should you can say the things have to be this way? Something like this has to work. Therefore, we got to keep going. That's the top down. And it's

going. That's the top down. And it's

based on this like multifaceted beauty and inspiration by the brain.
