0:00Today's models are just giving you the output. Tomorrow's models will start with an output reason, illicit feedback from the world, go back, improve the reasoning. That is the beginning of, I would say, the real reasoning era, the biggest beneficiaries of the commoditization of foundation models and the application layer companies. This is 20VC with me Harry Stubbins and more to show we have for you today with Aravind Shrinivas, co -founder and CEO of Pplexty.

You have now arrived at your destination. Arravant, I'm so excited for this. I've been looking forward to this one. So first off, thank you so much for joining me today. Thank you for having me, Harry. I've watched all of your episodes, so looking forward to it. That is very, very kind of you, my friend.

3:17Listen, I want to start with a little bit on you. How did you first fall in love with AI and realize that actually this was what you wanted to do and spend the majority of your career on? More like an accident. I was just yet another electrical engineering or computer science undergrad doing my courses and doing some interesting projects alongside. There was a point when one of my friends in undergrad told me, hey, there's this Contest, where you could have been in some price if you came first. And I think I was like kind of like a need of money because I was unsure I was going to get an internship so I tried to try the contest out.

3:52It was a machine learning contest, but I didn't even know what machine learning was. All I knew from that guy was that, hey, you're going to be given some data. You can use some of the patterns and the data and use it to make predictions on held out data that you don't have access to. server will have it, you submit your algorithm and it will score against what is correct and what you predict and whoever wins the most number correct predictions wins the contest and you get the price. And I go and check out this library called Psychit Learn. It's a very popular machine learning library and I have literally no idea what any of these words mean like decision trees and random forest like none of these things may any sense to me literally just did it what an AI would do brute force random search, but as a human I did all that and we won the contest, I won the contest, and then that gave me a lot of confidence, okay, I beat people who actually knew machine learning in it, and that gave me a lot of confidence at, like this is something I could be pretty good at.

4:49I remember Sam Altman once telling me, I asked him this question like two, three years ago, hey, like how do you identify something where you're naturally good at? And he said, whatever comes easy to you, but seems hard to other people. Like that's a good heuristic to identify things that you could be like mu plus two sigma at compared to the rest. So I felt like, okay, this machine learning is a good thing. It was not called AI. So I got into it and I did all the courses, pattern recognition machine, like the book written by Christopher Bishop. I bought it second -hand in India, something like $2, $3 and started reading it.

5:24And I really enjoyed it. Like it was pretty mathematical but also intuitive at the same time. That got me access to a professor, Rich Sutton, and Andy Bard a student and he was teaching at my undergrad institute. I told him to advise me, give me a project and he was a reinforcement learning guy. So, reinforcement learnings when I actually got into AI. Because while we're in AI for like checkers or like ticked actors or something like that, like you know, or even when you play chess as a kid and you play against a computer, you always ask questions, how does a computer play? Like what is it? And then they call, oh yeah, second AI, you don't worry about it.

5:59So they use AI loosely there, but the real definition of AI what it is like, oh, it's an agent, it's an environment, it receives a reward signal and optimizes for an objective. All that framework mathematically, mid -sense three, once I studied RL, and then he told me at the end of the class, yeah, how a friend of mine from UK, David Silver, you know, we used to know each other from PhD days, and his startup just God bought by Google for like half a billion dollars because they wrote this paper that learned to play Atari games just from the screen pixels. They've open source the code. Why don't you take it and now figure out how to play all the games simultaneously, like not just one single game.

6:39You learn to play a pong. You should be able to play a breakout much faster than learning to play a breakout from scratch. Transfer learning. So that was the first project I actually worked on. I loved the idea of all the papers that DeepMind did and I would just like literally be in the lab all the time and Keep reading their papers trying to like implement them and like borrowing gaming GPUs from other people in the lab and using it to train Your own that's on it. I was thinking before this like what are the single most pressing questions right now And what do I most want to ask and I think the first one that came to mind for me and when I had so many people message me when I put out about our show So the first one was one of diminishing returns and it's when we look at model performance.

7:19I think we've always had this kind of belief that you throw more compute and you get much better model performance. Do you think we've got into a stage now where we're starting to see diminishing returns? Yeah, I think it's a nuanced answer. I can just say no and you would be like, okay, if a brute force still works, but that's not the reality either. It's not like if I suddenly came and say, Harry, take my $500 million and go build a big cluster, take like trillion tokens and get a model better than OpenAI. It's not going to happen like that. There is still some alpha left in making these models bigger and training them on more tokens.

7:56But you would only get the bang for the buck if you put a lot of effort into curating the data. Otherwise, it's just not worth it. I know so many research labs, I can't obviously mention who they are, but who train really big models on a lot of data and ended up with nothing. It's a lot about what data you train on, how you mix English and other languages and code and math and all the chain of thought reasoning. Then how does it play out in the scaling law in terms of Shinshila optimality? We later discovered even Shinshila was not optimal. It was just a guideline. Then how do the mixture of expert models be more computational efficient?

8:38All these things matter. That's I think like those would do it right those would get these 128 details right are the ones who end up benefiting more from more scale and that happens to be like three or four labs at this point and I'll just give you an example don't judge me here judge Arthur of Mistrah when xai released the model the open source first croc and Arthur tweeted saying that's a lot of superfluous parameters because the model was 300b or something and was not even as good as the Miss Strauss 7x8, 56b. You could train a model that's like 6x larger and end up still with the worst model.

9:17You could have spent a lot more money and end up with the worst model. So if you talk about the kind of curation of data there is kind of the central factor in terms of determining quality of performance. I had read Hoffman on the show actually earlier this week and he said actually that we will see the kind of verticalization of models that you will use different models for different things. Is that where it leads to then? Is that what you're pointing towards? No, I actually think that viewpoint is flawed. I used to think that it'll happen too, but I can give you another example that defeats that purpose.

9:48Bloomberg spent a lot of money training, Bloomberg, GPT. They even wrote a paper on it saying that trained their own foundation model, and that model is beaten convincingly by like the GPT -4 on all the finance benchmarks. How do we know that's not case specific? It could be they just bought the approach in the wrong way, they didn't have a good enough team, whatever that is. It doesn't necessarily disprove verticalization of models, does it? The question I'm trying to pose here is that what is the magic in these models? Where is it coming from? These models are magical. You're not training them for what you're using them at test time.

10:23The way you prompt and use these models as if they were a human in the chat window is not what they were trained to do. They were just trained to predict the next token on the internet. Sure, they were fine tuned a little bit to be good at chat, to be good at instruction following all those things definitely. But that is just a very small amount of compute that was applied to these models. So what makes these models magical is the general purpose emerging capabilities. The fact that they can do things without being taught how to do it, or they can catch things on the fly with some little bit of prompt instructions.

10:57Now Now that doesn't come from any domain specificity. It comes from the emergence of training on so much. These neural nets are amazing that if you just throw very diverse set of data at them, the pattern match on the abstract skill required to be good all of them at once. And that abstract skill, that abstract IQ is what is making these models amazing for you on practical production use cases. So when you are saying, oh, I'm just going to go and make a domain specific, how many Many tokens you do even have in the domain. Think about it. Code is probably the only domain that actually has a lot of tokens.

11:31You can throw a lot of enterprise data at a model and say, I have a lot of internal data that nobody else has. But that doesn't mean that these models will absorb a new kind of reasoning that they couldn't get from the internet. It's very, it's one of those things that very few people understand, why are these models even good at reasoning? It's not well understood. Is it because they're training on math? Is it because they're training on code? And even that is not well understood today. Like, how do you train the model on just textbooks? Would you have not gotten reasoning? These are questions that we don't yet have good answers to.

12:05Do you think models are good at reasoning one? And then, I think like a breakthrough in reasoning will be one of the biggest breakthrough moments in the next wave. How do you feel about where we are today in terms of quality of reasoning and what is required to break through in the next wave of reasoning quality? I mean, it really depends on what you call as being good at reasoning. Are they better than an eighth grader? I think so. Are they better than like 75 % of the 12th graders? Most likely. Are they gonna be within the IMO or IMOI? No, definitely not. So there's like a spectrum, right? Love people good at reasoning even among humans.

12:41And I'm sure like AI is like somewhere like in the median right now of like high schoolers. Can it get to like a median college undergrad? Definitely. It seems like we're on the pathway to getting there. Would it be like talking to Faraday or Einstein? Not anytime soon. Some people call it as artificial superintelligence. And like I think when we achieve that, it'll break all this $20 a month business models. Have you watched this movie, prestige, where there's like magicians, you know, competing with each other? In that, like there's Edison, and this magician wants to steal a trick from Edison, and on how to make things disappear.

13:18He's willing to pay like a lot of money just for that one trick. And I think that's the sort of thing you would get to models got really good at reasoning, where just for the output alone, is you're not even paying for a monthly subscription of paying for one single session, one single chat, one single output. You would pay a lot of money. You're an investor, right? If I literally told you which company's, hey Harry, listen, I got all the inside information and all the revenues, blah, blah, blah, if I can even tell you, Or let's say even if I didn't have any insider information if I was such a good reasoner and I gave you Harriet This is gonna be the set of companies that actually matter to you so now And I gave you such amazing reasoning that you probably would have had to spend like two months talking to 100 people Then would you have paid 10k for just that out answer?

14:04You're probably paid 10 million exactly so even if you pay 1 % of the ROI it will be worth it People at the level of say, Demis is a sabas. Look, they're like incredibly smart like who's going to advise Demis? You can count the number of people like in your hand, right? And if Demis feels like there's an AI that can advise them, what's the value of the AI? It breaks all your mental miles of like 20 -hour months. I think that's what is lacking. If you say it, do we have two reasoning? The benchmark for two reasoning is an AI that can advise sabas. You don't have that today. But there are AI that can advise a person may be making 120k a year in UK.

14:40I think we can get there. This is where you got to clearly be precise on what good reasoning is. I understand that in terms of the precision around good reasoning. When you think about the trajectory of reasoning quality, how do you think about the timeline there? Do you think it goes up, flat, up? Is it a continuous gradual increase? How do you think about the trajectory and slope of reasoning improvement? I don't think we know the secret sauce yet. Alisa, according to writers, media writers, they claim like opening eye has some new thing called Q -star. They are working on to like make these models like use their own data to bootstrap and make themselves more intelligent.

15:17XAI recently hired this guy Eric Zellikman from Stanford who's written these papers on something called the star, self -taught, automated reasoner. Basically, you think the model itself and trying to make the model explain its own outputs and then whatever is the right output you train on that or it was a wrong output you take the right output and then you ask the model to explain why that was right and train on that you basically are training on not just the output but also the explanation that was used to achieve the output and if you can do that you're basically training a model that can think and reason and get to an output see if it's correct go back reason again and iterate that is what is lacking in today's models.

16:02Today's models are just giving you the output. Tomorrow's models will start with an output reason, illicit feedback from the world, go back, improve the reasoning, and until they converge, they'll keep on trying to improve the output. And I think when that is achieved, I don't know when that's going to be achieved. Maybe you'll be achieved in a year or two, maybe it'll take three, four years. But I think when that is achieved, that is the beginning of, I would say, the real reasoning era, where we'll figure out how to make these things more efficient, we'll be throwing a lot. The only problem here, this is a game that won't be played by academics like before.

16:38Because just to do the inference compute, to do all these reasoning, getting an output, going back and reasoning, building a rationale, then going back and getting another output, just to even do this process, takes you a lot of inference compute. You have to pay money for this. And so even a single experiment costs you a lot of money until you arrive at the truth of the algorithm. and then that algorithm to run it is going to cost you a lot of money to get all the data, synthetic data to train on. So I feel like this is where companies with a lot of capital are going to be way more advantaged to pursuing this research.

17:11So if it all happens, it there are only like four or five contenders to do this and whoever ends up with the algorithm, the first has a massive advantage because it seems is too good to be true, so I think where once you crack it, you can just keep throwing more computer and get a big lead over the other models. We are absolutely going to talk about the funding required to finance these models. I do just want to stay on performance and capabilities. Why is it so difficult to have models with memory? Everyone says, oh, memory is the challenge. I don't understand why. Can you help me? There are two things here to consider.

17:45What does memory mean? Is it like sufficiently long context that's practical for most use cases or is it infinite Long context like basically there's an AI for a hairy that remembers all your life Every single aspect of it every single detail that is like infinite memory And I think like we don't even have the algorithms for it yet today And then there's another AI that sort of like is like Gmail sort of a thing where you know It starts off with like a sufficiently large storage like it's practical enough And it keeps expanding over time. And then now it's like throttle, beyond which you have to pay $10 a month or something.

18:22That seems more like where we are headed right now. Like people are expanding the token window from 128K, like server 32K, and then it goes to like a million, then deep mind and ounce, two million. I feel like that is already good enough, where at least we can prioritize and throw out like what's not relevant and like keep using memory. And as you said, that's not very hard to do. There is one small challenge there though. It'll be figured out but today's case is that we have achieved long context before achieving good instruction following. So you can dump a lot into your prompt. You have the memory but modus can hallucinate or get confused because of so much information to focus on.

19:02So you need to ensure that the instruct following capability has no degradation despite adding all this long context capability. I think that's not the case today, which is why these models are not so good at, they can just write an entire code base yet. But all that will happen. I think it's just a matter of time before they run another training run and figure out all these bugs. But the second thing I'm not sure how to do, in finite context, I'm not sure. When we look at the different foundation model providers, I do just want to move to the ecosystem itself. And before we touch on the funding itself, I just look at it and everyone says that we're seeing the commoditization of foundation models as you know, I'm just interested to hear your thoughts.

19:42How do you see the end of state for the foundation model there? Are they getting commoditized as people say? I think today the work commoditization, it's sort of true in a sense, a model that's like 75 like GPT 3 .75 level model is commoditized. There are like too many models like that today on the market, some open source and some close source. I think GPT -4 quality models are not yet commoditized. There's only probably one or two alternatives for the people today like Claude Opus or Gemini let's say. So if it's just like two or three alternatives it's not I wouldn't call it a commodity yet.

20:19But will it be commoditized? I think so. But by the time it gets commoditized would there be a 4 .5 or 5 that's way better? TBD the training run is happening, my prediction would be that would be another great model. After four, that's like very good. Like I wouldn't say GPT -4O is like a lot smarter than GPT -4 Turbo. It's more reliable, better, it's faster, cheaper, but it's not like how four blue three point five hour water. That sort of thing, whether FIKE and do that to four would answer your question of whether these models are getting commoditized. This is not like a bad business unlike any other before whereby you every six months have your core product Basically made redundant.

21:02Is that true though? Like I mean, I saw your interview with Altman and Brad Lightcap But is it actually true that like a product gets redundant because the model gets in him great I think so is GBT 3 not like redundant now that you wrote GBT 4? Yeah, but your product is never the model Let's maybe decouple this if there are companies that are working on foundation model competitor to OpenAI. It is definitely like one of the worst arenas to be part of. Almost like I think there are five men standing today as often thing. Google and Anthropic meta, Mistral and after XAI's new funding run maybe you can include them too.

21:39But that's a game that like is so hard to play and I'm very impressed that Mistral was even in the arena with like 10X lower capital than the rest. Are you not in that same arena? We post train models. We post train them. We're not foundation model trainers. For example, we can take any model that's there in the market today and Shape them to be really good at what our product does including like open source models and like making them really good Have we trained a base model when you say there's like a llama 370b There's a base model that's just trained on predicting the next token and then there's the Supervised fine tuning and our HF steps that train them to be very good at chat and like instruction following, summarization and translation, all these skills.

22:23Now the second part is what adds magic to the product. Without that, you're not going to have these good chatbots. But the first part has the base IQ. That builds the base IQ for these models. Are we not doing the first part? It's a losing game almost to play the first part because every time you end up finishing a large training run, you've earned a lot of money, you have a great model, and then you watch it destroy and the leaderboard by the next update. And then you have to again catch up, you go spend more money. So where, how are you recovering all that money back? You may recover that through the APIs.

22:57Nobody wants to use the APIs if somebody else is just offering a better model, a cheaper price and faster. That's why I think it's a hard game. Now, it's not a hard game because it's hard to train these models. Sure, the science behind it and the people, difficult to assemble. But ROI -wise, like business wise, it's very difficult to compete here. Is that not what we're saying though about the commoditization of models being you get to a stage Oh shit everyone's at that stage. We have to do the same again. We have to do the same again same again Your your model becomes redundant. I think there's second tier models that are not the most cutting edge But cheap enough to like operate a business on top of it will get commoditized But there will be some frontier models that are like so smart and I think those are still that's still a game being played by like three or four people today Does that end is three or four people or does it end as one person?

23:46I think the answer to that really lies on who cracks, who would strap reasoning. You know, the thing we talked about a little bit earlier about models using their own outputs to reason and improve. Whoever cracks start first, if they allocate all their capital on just scaling that up, I think it'll end up as one person. But if they're hedging, hedging, hedging, it will end up as one person. Who do you think that person is most likely to be? It's likely to be open AI and anthropic. I can make a good case for both of them open AI because they are far ahead in terms of the lead they had and in doing these things first andthropic because they're algorithmically a superior company.

24:25They got whatever open AI got to with lower capital. They have better post training and things like that. So, OpenAI is on the other hand like, advantage on capital and speed. So, it really is like a question of who, you know, which matters more. Is it clever brains or, and like, some amount of capital or is it good brains, a lot of aggression and a lot of capital? If it's a second, it's OpenAI, it's the first, it's anthropic. I think that you're going to see the kind of large cloud providers realize that they need to acquire these models in different forms and they will continue their core cash cow businesses as cloud providers, but they will acquire these models and add them in as complementary features that they already provide.

25:07And you'll see your anthropics, your co -hears, your see your adapts acquired or acquired by these large clown providers. Do you agree with me in that prediction of the next three to five years in terms of how it shakes out with those acrohires? I don't think so. Why am I wrong? I think with OpenAI and Anthropic, the value of those companies is not in the models they have. That is a very first -starter approximation. I think the second order approximation is it's in the machine that's building the machine, the specific group of people with all the tacit knowledge required to train these frontier models and innovate algorithmically on what is likely to be the real reasoning breakthrough and the accumulation of compute they have is the reason why they are valued at this price where the revenue and the valuation make no sense but they are because always I think about valuation is like how easy or difficult it is to reassemble this whole thing.

26:01And the thing is not just the output. The thing is also the machine that gave you that output. When you say models are getting commoditized to open air and probably going out that valuable, I disagree because these are the same guys who will produce the next model. Are those guys getting commoditized? Like the talent? No. In fact, it's getting the opposite of commodity. Like they're all being paid a lot of money to stay in these companies. And so the knowledge only stays with them because people don't publish anymore. There was even a joke I recently got a hangout with one of a very great researcher even made a joke that the best research is the one That's not being published today and like so there's nothing to read on archive anymore So even the guys that stand for to wrote all these reasoning papers Yeah, now like Musk paid them a lot of money to work for him So he's not gonna publish anymore.

26:47That's what's happening. It's the commodity is not the model the commodities and the people who produce a models and that's not a commodity yet. So that's why I feel like these companies are valued a lot and they have so much leverage that they won't get acquired. Like if these people don't want to go work at a big company and the big company needs the output to keep doing their business, like Microsoft needs GPDs to sell and make Azure the number one cloud AWS needs cloud to sell to make continue to retain the lead in the cloud market. So they have no need or like desperation to get acquired.

27:20opening an anthropic, I don't think are gonna get acquired. Now, the flip side is that models, they don't produce any breakthrough. Scientifically, it's not possible to keep cramming one more token set this in, keep seeing the juice. That's when what you said is like, it happened. If like, say, after even one year, opening a doesn't have a better model, yeah, then the leverage goes away because it's over this, you've got to actually produce a new thing, and the people are unable to produce it, so their value goes down. And we have to play it out. I think both of these things could be true. I think these guys are still produced breakthroughs.

27:55So that's why I have a different prediction. But time will tell us honestly who's right. We mentioned kind of access to capital that, obviously, opening eye slightly more than anthropic. The thing that struck me was when I heard that, you know, Mr. Olesney funding round in terms of size was about 30 hours of Microsoft's free cash flow. In Microsoft's $330 million in free cash flow per day. in a world where that is the case. Not cynically, but just genuinely. How does anyone compete? Like, you know, your room would be raising and it's room you don't need to comment at all. Like the amount that you raise relatively, it's just insignificant compared to Microsoft's free cash flow.

28:34How does one compete in that world? That's why you got to build a business. First of all, let's separate the two things. Why, if Microsoft is generating the art much cash flow, why are they not able to poach all the open AI scientists is a mis -raw scientists to come work for Microsoft. Like they could take that money and ask one of those people to, like ask like 10 of those people to come work here and I'll pay you a lot of money. No longer need to work at OpenAI. It's just directly build the AI is here. Whatever GPUs I'm giving for OpenAI, I'll give it to you directly. It's not happening, right?

29:05For the reason, people want to work with other best people. So it's not enough to get one person, you have to get the whole thing. That's why there were all jokes, you know, when the whole board drama was happening that Satya acquired OpenAI at a small price because he got the whole team out. I think that's the difficulty here. It's cash flow doesn't change the dependence issue. And if they can get these models from people other than these two companies, yes, that changes the equation a lot. They can just get it from open source and sell the same models and make a lot, same amount of money with less spend.

29:41Then that is bad news for the foundation models. As for like what is the way out of your I think like you got to build a business yourself It's fundamentally every company that raises capital has to eventually build a business or Hope that like their algorithmic promise keeps staying forever I would bet on like those who are serious about building a business like opening a business for what it's worth I think they they have like whatever two billion in revenue annually Which is like higher than snowflake or at least like as good as snowflake In not as capital efficient as Snowflake, but in the same league in terms of recurring revenue and growing faster.

30:17So that shows you that, like, you know, if you are serious about not just training these models, but also like getting it to the market through products and making revenue out of it, there is a potential for you to, like, be independent and self -sustaining. Are you focused on building a business today? Yeah. We're going to move away from the 20 pounds per user. It's exactly what you are, 20 pounds per month. And I don't think that business is actually that good. it's not high margins enough. It's okay. If you can get to like a YouTube level thing, sure Netflix, YouTube user base, 50 to 100 million people paying for you, definitely that's a great business.

30:52I don't think we are at a point where these AI's are so fundamental to people's lives that like 100 million people are subscribing to it. If they can get there, if you can build a product that's not just AI but has a lot more things to it and people pay a lot of the monthly fee for it and the retention is like close to 100%. Yes, that's a phenomenal business. And I think we will try to do that too. But all these great subscription businesses are also doing ads for a reason. Margins, right? Whatever we criticize Google for, the greatest business model, like in the last 50 years is that click -based advertising.

31:28It's just insanely good business model. 80 % margins. What was the internal discussion with you and the team when you were talking about adding and advertising and as the monetization engine. Just take me inside that conversation. How did it go and how did it net out? You know this is whole Larry and Sergey beach rank paper that say I said like advertising is fundamentally incompatible with like serving good resource to user in a search engine. I mean they truly believed that and like have read books that said like they push back on introducing ads as much as possible until they gave up your investor pressure.

32:03We were like, look, let's be practical. This is the most highest margin business model ever invented. But let's do it in a way where we don't have to be as high margins as Google. You don't have to aim for that 80 % margin, like as long as you can get a reasonably good high margin business without failing on your duties to user, be happy, like don't be greedy. What is the way to do ads without corrupting the answer As in you make sure that the answer is not like influenced by the ads and if you can ensure that I think it's a great I think it's a great idea to explore. That's why we have other other surface areas to add to like even the discover Feature and complexity which has like you know a bunch of threads interesting threads every single data like read That's just gonna be like an endless scroll at some point Instagram does ads in that format to take to talk this ads in the format So add this a great business model and when it's relevant, it's amazing.

33:00Like I've literally not met one single person who came and told me Instagram and suck. It's actually pretty good. It's all about cracking the relevance code. Like if you crack the personalization and relevance code, add this like pretty amazing. Do you think you've cracked the relevance code? No, not yet. If you're cracked it, I think we should be worth way more. It's like a chicken and egg problem. It can only be cracked when you have a lot of users. So advertising is one of those funny things where there is no way it can work well when you don't have a lot of users. And then when you have a lot of users, it can work really well if you get all the details right.

33:32I was talking to Mark in recent ones and he told me how like in advertising it's like three to years, but like the top tier is like Google. And then like one and a half, one is Google, one and a half is meta because even between Google and meta, Google benefits from every other advertising other people do because at the end once you discover the brand, you go to Google and click on the link they have. It's amazing like how they benefit from everyone else's hard work all the time. Then there is like companies like Twitter and like Reddit and Snap and he said the gap between these two is so high.

34:03This is like almost climbing the peak of the mountain and this is just like somewhere in the bottom. That is the extent to which ads have been dominated by like Google and meta at this point today. My point is that if we can get the fundamental mistake that Google made right in our journey very early on where we are overly greedy on one source of revenue and are diversified enough through subscriptions, advertisements, APIs, enterprise. I think we have a chance to build something that achieves the alignment between shareholders and users a lot more. Jeff Bezos has scored red that asymptotically, the shareholder and the user should be aligned.

34:42If not, then you don't have a customer -focused business. This is where Google got it wrong, because asymptotically, they couldn't achieve that alignment between the user that is you using Google and the shareholder. Wall Street allows it when Google puts more ads. You hate it. You mentioned OpenAI eyes, two billion in revenue. A lot of that is the enterprise, and they built the enterprise incredibly well. You kindly mentioned my show with Brad where we actually kind of touched on it. How do you think about when's the right time to build our Pupplicities Enterprise Division? The number one insight that motivated us to build this was, what is the most used enterprise tool today?

35:16Google. You search every single day at work. All the data is something internal to your company as in the specific queries, but nobody cares because you need it You cannot live without it. You pay for it through your time and you pay for a three -year data This thing changes in the AI native search world where they're always worried about data leaking to AI They don't care if data leaked to a traditional search engine But if the search engine now has a lot of AI and they're worried so we said okay if you want to use for flexibility at work And your employer doesn't let you use it We'll solve that problem for you.

35:45You'll offer an enterprise probe with compliance and security and data governance and literally offer you the same product with all these security features. And that became our enterprise probe. Now, that's just the start. You need features too that are more catered to the enterprise than just the consumer. And that's what we will build. And we want to build in a pretty differentiated way, rethink what even internal search means. Like not just compute pipes to every single enterprise tool like Slack or Notion, But really think about like like what what is like the ranking problem? Why is it hard for the enterprise compared to consumer and like if we can be like one UI Where all the proprietary data external data internal data all the different models open source close source Live in like one single platform.

36:27You know, you can take your output convert good readable pages Organize it by book like as a knowledge base indexed yourself That can be a good enterprise offering. I think we'll work on that I'm not saying we'll succeed at it, but we'll try to do something. With total respect, are you nervous about building an enterprise product? When you look at the GTMs, it is a very different motion. Enterprise is a big beast to get your head around. It's a challenge. You said that about the scale of OpenAI sales team. How do you think about getting your head around the GTM building exercise of an enterprise division?

37:01Did people buy complexity enterprise and OpenAI enterprise? Or either all? My sense is that like AI is still so early today that nobody's locked in a loyal to any any particular An appress to in AI and none of them even have a lock -in effect to like make your data live on like one single To I'm not even talking about things like why is it hard to migrate from snowflake to data bricks because of the sequel format It's so different and once you wrote all the sequel varies in one format so hard to change It's not even things like that in the eye like your custom prompts that you wrote for chat you can be taken over easily to Proplexity.

37:39It's very easy. I think enterprises are still willing to tinker and experiment and try different tools That said if there is no differentiation they will win in the beginning the one with the bigger brand and Bigger team as an advantage, but is it game over? No, it's just game begins today. That's how I see it I think like this is exactly the whole wrapper thing and I if the value you add is like a very little on top of the model or if the model is the one that's adding most of the value and all the stuff you built around it don't matter Yes, but if you build enough value around the model that is very difficult to do without coordinating a bunch of other Hard to achieve engineering feeds that are not just LLM spaced or like how a lot of human element involved in it It is difficult to see a world where like like that is not valuable and people don't want that you know the specific search thing Why is it that like Google AI overviews was bad.

38:31They have the worst grades index, they have the worst best models too, but it wasn't good enough. Or why is it that people still think chantivity browsing is not as good as perplexity, despite them making so many updates over the last one year? Why is perplexity browsing better than chant -gbc? I think it's just a lot of small details. I'm a big believer in those who can orchestrate models and data sources and build great UX and and keep innovating here all the time. We'll survive this whole wrapper argument. I think it's just like gonna be difficult until you build a business where everyone's always afraid you're gonna die.

39:10But as you are accumulating the users and as you are figuring out the business, it feels to me more like the biggest beneficiaries of the commoditization of foundation models or the application layer companies. Why is that? Yeah. If models could commoditize, then the price of the models goes down. And then those would directly reach the user using those models harnessing the power of those models, but packaging it into like great product experience and utility value directly own the relationship with the customers, the users have a lot more advantage because they are able to like take something that's a commodity and sell it at a premium, which is a great business.

39:46If models get commodity as I'm happy, if models don't get commodity as I still want to figure out a way to benefit from that. That's why this is a great difficult company to build. It's not something where you just hire an SVP of product from Twitter or meta Ask them to figure out product for you. It's not easy. They don't have the mental models of like what happens When the next AI model is so much better. How do we think the whole product strategy? Similarly, it's not something where you hire a great AI person and ask them to like build product because they're always gonna Think the models and most important thing and keep trying to do everything through the model You need the right sweet spot of design and product and AI and search all together and that assembly is not easy And that's why we are able to do things as a rapper that other people are not able to do have you been surprised by the fundraising process Fundraising processes are brutal.

40:39I think most people think like you just go to like there's always these memes about like if it's an AI people are just like willing to write your determinate without even doing any diligence. Well, like, welcome, like, why don't you try to raise it's pretty difficult actually. Everyone's asking all the questions that people on Twitter roast the rappers with. What happens with opening at us is what happens with Google does this? What, what, what, you know, why would they not stop giving you models? Like, how will you build your own models? Like, how are you going to have a build a search index?

41:08That's like really good. You know, what, how do you compete on the enterprise sales? All these are questions that everybody already asked and like, and you don't have a good model the future yet. You have to give them good arguments, but at the end of the day, it's all like arguments, nothing is there. And one thing that we do have in our favor is like a good track report of execution. We've been around for like less than two years and amount of things you ship. This quite a lot compared to the team size and funding we have of the cash rates. How much goes to compute? Most of it, like 50 % like 75 % just first of all, of money.

41:44Most of cash we raise has already gone away to compute. No, whatever money we spent, majority of it has gone to compute. And the compute is either us buying GPUs and serving models or post training models or money we pay for APIs like Anthropical Open AI. That's fine. As long as that's why it's very advantageous to us to not train our own foundation models. Because if we were doing that to most of the funding would have run out because the way it works is you have to pay three years in advance to get a big cluster. Like you have to commit to that. It's not like all the money goes away immediately, but you have to commit to three year to get like thousands of GPUs at once if you want to compete in that game.

42:24On the other hand, we're not doing that and we benefit from any commoditization of the models. We have all the money to go and get users and getting users not simply through like marketing but actually more in the Amazon Prime sort of way. giving a lot of great features at like amazing prices, getting to retain you through superior product execution and then like you know buildings of like a sufficiently large user base and brand loyalty. That is the model that we're going for in such a world like advertising can be pretty powerful at that scale. Every business has a core monetization engine. They have ancillaries but there tends to be one which is dominant.

43:01When you look at you know a plasticity in five years time what is your dominant engine is it consumer misubscription? Is it advertising? Is it enterprise? I would predict it'll be advertising. If we crack it, yes, it'll be advertising. If we don't crack it, if we are not, if we don't, if we haven't grown to that level, in use a basin or if we grew and didn't figure out how to advertise really well, it'll be the other two. Either way, we can be profitable. I think with advertising, we can be really, really profitable. And then you can ask Hey, why do you care about profits? Like Sam Alman doesn't care.

43:33But he doesn't care because he's not interested in actually just focusing on product as a business like he's trying to build AGI. And like he already told publicly in an interview that even if we spend $50 billion on AGI, it doesn't matter. So that's a different company. That's why like I'm saying, we're not, we shouldn't be seen as an opening I compared it at all. We're not in AGI lab. You can say a perplexity and charge EPT are products in the similar space and there's like some competition for mind -sharing users. But even that will like be pretty clear. And like two years from now, you're not gonna keep asking How is for black city different from chat to be deep today?

44:05You are but two years from now I don't think so if that's still the case one of us is just copying the other What do you think is the best question you are never asked? I think someone asked me like why are you doing this? This is our question where you don't actually know yourself. I think a lot of people give these Made -up answers like oh, I had an existential crisis. I needed to save humanity reality is like you just look up to some people you want to be like them and you try to carve your career path according to what they have done but then you end up like figuring out there are things that you really like and you shape it to the style you want and at least that's how it's been for me I have been a big fan of Larry Page and I always wanted to do some things on that scale of ambition that was not the reason we did search engine though like we started with something else completely.

44:54That's a question that I actually don't have their answer to but I really liked the question because it's a question worth asking yourself constantly like why are you even working on this? Steve Jobs has this thing right? Like if you if you internalize death, if you're normalized death and every day morning you stood in front of the mirror and asked if today was my last day would I still be doing this? And if the answer to that question is yes go and give you a best a day. If the answer to that question is consistently no on a you know a regular basis you really have to rethink your life priorities.

45:25And for me, like, proglesis, yes, like, hell, yeah, like, even though it's painful, takes a toll on mind and body, I think it's worth it. You're still looking incredibly young, so don't mind. It hasn't aged you, Arvin. So, all good there. Thank you. I'm hiding my gray hair very clearly. Listen, I do want to do a quick fire on. So I say a short statement, you give me your immediate thoughts. And I'd love to start on, what if you changed your mind on most in the last 12 months? Long term view on people, seen some people like not immediately hit the ground running, but give them sufficient time, they are able to like, truly transform themselves.

46:01It's something that I didn't have the right attitude towards in the beginning where I always thought like those who hit the ground running immediately are the best, but you know different people have different styles of showing their true dance. What's the biggest misconception in AI today, do you think? short -term thinking. Like, anytime somebody comes up with an update, everyone's like, the other company is done. This is over. The usual Twitter mob, but I would say the biggest misconception among even the more bell -in -fom people is that because majority of the people in the world are not using chatbots, they just think this is a bubble.

46:36They are going to get really surprised that it's not a bubble, it's not over -hyped, it's actually underhyped. These things when taking in the right workflows and form factors that you're already familiar with, will have a lot of impact. Chat UI is a new UI. We're not used to using it. We're all used to using WhatsApp and Signal and all that, but that's different. It's not exactly a chat. It's more like a texting service. On the other hand, word, docs, Gmail, Google search. I'm not even talking about the specific products, but more like the form factors or usage, the UI is, you're very familiar with it.

47:08And when the AI is presented to you in that sort of a format where it feels so obvious and natural as a workflow, it'll have a tremendous amount of impact and it's not really happened yet. Have you seen WhatsApp's integration? It's not the right way to do it. Why? I'm not going to WhatsApp to search for anything. I'm going to WhatsApp to text people or reply to, my WhatsApp most of the times is just having like 20, 30 notifications and by the time I'm done with them, I just want to get away from the app. I'm not going there. I'm not pressing on WhatsApp icon to like search for something. Same thing with Instagram, I'm just going there for pretty pictures.

47:42I'm not going there for searching about like who's one the NBA. It's just the user intent behind opening the app matters a lot This is the same reason why they failed multiple times at doing stories and reels Story started off as a way to copy snapchat as a separate app first that didn't work Then they tried so many different variants What really ended up working is the top bubbles and that only works because you you're starting with the existing user flow So you're already going there to check out other people. So you have to really think about like not just like why this feature is added, but what is the existing user intent in your app?

48:18And how can you make sure the new feature you're adding ties into the existing intent? That's very important. What's your vision for the future of browsers? I think you can reimagine the browser when agents start working. There's a reason why we never did a browser. I don't think browsers gonna be disrupted because you get answers instead of links People still want to browse and get to a new website get to a specific website Enter details fill up forms all those kind of things that's not really getting disrupted with the traditional chat UI It's just because you can type in like on perplexity on a search bar.

48:53Let's say that integration is done I don't think you will allow the browser more or something. It's gonna be more productive But you need the traditional browser functionality a lot What will change though is you go to a browser, you just say start the podcast at Arvind and already knows exactly, Riverside, it has to go like, fill up your logins. After that, it's just over. That would be amazing. That would change everything. Like, buy me this thing on Amazon. Like, it's sort of like completely, then you can go a step further and say, like, what is the future of the OS? Like, what's the future of Mac?

49:27What's the future of Windows? So browser is just an OS too right? What do you think is the future of OS then? I mean something like the horror movie can't work. Like, you know, not talking about the voice, but the OS itself being an AI. Completely AI, I need a OS like, you know, start organizing a traditional way. And you just talk to it and it just work for you. That's amazing and vision to have. And that's the sort of thing that doesn't work today. GPT -4 cannot do it yet. What is the hardest element of your old stay that people don't think about? that people don't consider. Dealing with contradictions all the time.

50:02I believe the brain is not very good at dealing with contradictions. It actually tires us out when we can arrive at a convergence point on something. And startup CEOs all about contradictions. Should you take a risk or should you like double down on what you have? Should you move faster or should you set up the company in a way that it can scale? Is it time to like try out this feature just because it's not something your competitors would do or continue doing what you're doing well, but your competitors are doing the same thing. You have to constantly deal with these contradictions in so many different dimensions.

50:36That's tiring. Penultimate one. If we were to write ENO, we write pre -mortems as investors. A reason why a company doesn't work when we write an investment. If you were to write a pre -mortem on a plasticity today, what is the reason why you don't achieve your goals? Access to compute, Google innovating and killing you. What is that reason? Didn't execute well. Comparison killed startup startup skill themselves. It's not that Google drive a kill draw box. People say that as an example, but there was like a great enterprise business to build a draw box that they didn't move really fast and compared to like other companies like box.

51:12Comparison are to start a startup skill themselves. So if there was a pre -mortem to be written about us, it's like CEO not making being decisive execution of the company not being good. lack of focus in efficient use of capital. Larger comes to whatever decisions have made, correctness of them, the speed of them, and execution of them, and whether we are focused or not. If these things are not true on a consistent basis, yeah I think we would die and that would be the pre -mortem. Final one for you. It's 2034. Why would you most like the complexity to be then? If we do a show then, where is the business then?

51:47It's a good question. I think I would just wanted to be the assistant for facts and knowledge you just can only without. You can ask me with ten years later do people even want facts? You know there's a thing where you have to always ask this question like what is going to be true even ten years so now? And if you work on that you're working on the right thing. I feel like even even in a world with a lot of AI agency and less of human agency people would still want to know what's true and what's not true. So we are working on that. So if we are the go to assistant for facts and accurate information and knowledge, I think we'll be fine even Daniels will know.

52:21Arvind listen, I've loved doing this. Thank you so much for putting up with my my straying questions, but you've been a fantastic guest and I so appreciate the time. Thank you Harry, it was great. I have to say I do just feel so lucky to do what I do. That was such a fantastic conversation.
