Tim Hwang: What would you do with $2 billion? Chris Hay is a distinguished engineer and CTO of Customer Transformation. Chris, as always, welcome back to the show. What would you do with $2 billion?

Chris Hay: Spend it all on bitcoin and tell people I’m training AI.

Tim Hwang: Okay, great. Kaoutar El Maghraoui is a Principal Research Scientist and a Manager at the AI Hardware Center. Kaoutar, welcome back. $2 billion. So, what would you do?

Kaoutar El Maghraoui: Well, it’s a lot, and there is a lot I can do with it. One of the first things is philanthropy and social impact; I would love to help with that.

Tim Hwang: Vyoma Gajjar is an AI Technical Solutions Architect. Vyoma, what would you do with $2 billion?

Vyoma Gajjar: I would go back to my roots and become a farmer again. Own loads of land, land, land. And then revolutionize the entire field of agriculture.

Tim Hwang: Terrific. All that and more on today’s Mixture of Experts. I’m Tim Hwang, and welcome to Mixture of Experts. Each week, MoE is the place to tune in to hear the news and analysis of the biggest headlines and trends in artificial intelligence. Today, we’re going to talk a little bit about a new CoreAI group at Microsoft, some new features coming to NotebookLM, and a little bit about agents in finance. But first, I really wanted to talk about $2 billion. We had some rumors that just popped up this week that Anthropic is set to raise $2 billion at a $60 billion valuation. And that follows on news from December where xAI raised $6 billion at a $45 billion valuation. Obviously, the market is really, really hot. Continues to be really, really crazy. I guess maybe, Chris, I’ll turn to you first. For our listeners, that’s just a staggering amount of money. What do you use that money for? What is this money being raised for? Why are these companies needing so much money?

Chris Hay: I think the quick version of this is it’s an arms race at the moment. It’s an arms race for talent. So, you know, the researchers aren’t getting paid a small amount of money, so they’ve got to be paid, and they’re pulling the best talent from folks like Google, OpenAI, etc. So it’s just the cost of the researchers, and then obviously the cost of the GPUs. It’s one of these races where if you’re not spending the money, you’re not going to be able to train the models, and then you’re just going to be out of the race. So I think they’ve got to keep racing just to be in that race.

Tim Hwang: Yeah, absolutely. Vyoma, one question that I have with all of this is, it’s pretty hard to raise $2 billion, much less $6 billion in the xAI case. I think one result of this... it does seem to me that is this becoming kind of a two-player game in terms of the ability to train these massive, massive models? Like, are we going to end up with it largely just being OpenAI and Anthropic?

Vyoma Gajjar: I believe that these players have a huge market share right now, but I don’t feel that they are the ones who are going to rule forever. The smaller models, the smaller industries that are taking up people who are more domain-specific and building more domain-specific models are also being entertained by clients. So I feel over here, as Chris mentioned, it’s an arms race right now, and I feel a majority of all of these infrastructure changes that are going to take place would need a lot of money going into them. So we’ll just have to wait it out and see what goes around.

Tim Hwang: Yeah, I think it’s kind of intriguing. What you’re saying is basically that these companies can raise so much money, they’re the leaders in the space, but it’s unclear whether or not that will allow them to retain their leadership in the market, which is pretty intriguing. I guess, Kaoutar, do you agree with that? This is in some ways maybe an interesting, ironic situation where the two biggest companies are going to be raising the most money, but in some ways are maybe the most vulnerable.

Kaoutar El Maghraoui: Yeah, definitely. I think this level of funding can signal also to other AI firms the level of resources needed to stay competitive, leading to a cascade of investments and potential consolidation in this space. So it’s definitely an arms race, like everyone said here, and some of these companies will be shaping the AI industry. So this is a rivalry in the AI industry fostering rapid advancements in both capabilities and ethical considerations. For example, Anthropic has a niche market here, especially with safety. They’ve carved out a niche emphasizing safety and alignment, which resonates with governments and enterprises concerned about AI and its safety, while, for example, OpenAI is mostly focused on the broad utility. But this doesn’t mean that they’re the only key players, that it’s going to be a two-arms race. There are others, and especially with the push, like Vyoma mentioned, with the smaller models, we will see. I think it’s still too early to predict what’s going to happen. There is also a big push for smaller models that are doing pretty well, especially in domain-specific cases, and those also will have a key role. But I think what this is showing is there are massive investments right now happening, and most likely Anthropic will double down on their R&D, which is going to be great in terms of the capabilities that they’re going to unleash, the development that they will do. So more innovation is going to happen in the space, but also a lot is happening in the open source, which will help others catch up or even come up with some revolutions here.

Tim Hwang: Yeah, for sure. Chris, maybe I’ll turn it back to you. You were nodding when Vyoma was kind of giving her hot take on all this. There’s a great book that came out from Stripe Press called Boom by Brynn Hobart and Tobias Huber, and they make the argument that there are good bubbles, which is that you can imagine a world where all of these resources kind of flood into the space, and the companies that are leading and driving this may not be the ultimate winners, but it’s not a count against the technology; it’s almost what’s needed for the next generation tech to emerge. It sounds like from your head gestures that you sort of agree with the idea that these may be the leading companies, but they might not ultimately own the future. We might not end up in a world where these two companies are the end-all, be-all for all AI.

Chris Hay: I think the caution I would have is that these companies are in competition with their investors, and that is probably an interesting dynamic. We’ve seen that play out already, fairly publicly. So I think it’s how that competition—whether it’s a co-opetition or whether it’s true competition—plays out. If you really think about those companies, they’ve made great strides, and their own AI capabilities are absolutely huge. The Microsoft Phi-4 model, for example, is a great model; the new Amazon Nova models, etc., they are making great strides. When you start to look at the hyperscalers investing in their own AI, and then, as we’re going to talk a little bit later on in the show about how AI is going to be embedded across their entire organization, is it really going to be a space for those companies to exist? I think that then opens up that they need to establish their own platforms, and we clearly see that from those companies, right, with things like the operators, etc., the more generic platforms. So we’re going to get this push between platforms, and I think that tension’s going to be interesting. That’s why do they survive or not? The only way they’re going to survive is to keep being expensive. And then the other one was hardware, of course, super expensive as well. This kind of interesting question here is, does that spend go 50/50? Is it going to balance out over time, or are we going to spend less on talent over time and more on compute? I guess, Vyoma, I’m kind of curious about what you think a little bit about that. I just kind of think about the balance sheet of these companies; they’ve raised the money, so they have these chips, and they have to decide, do they put it more against talent or more against compute scarcity? Do you think those economics will sort of change over time, or if one will dominate over the other?

Vyoma Gajjar: I think the future would be how we easily and properly strategically balance all of these. As you said above, the race is actually to dominate over this entire AI ecosystem that everyone’s building, and everyone wants to kind of have their beak into this. One of the main things that I feel—and this is some sort of an indirect control that all of them want—is the pace of innovation. Imagine the amount of money that you put in, that much compute you have, that much access to researchers you have. If you put out such investments, and then this comes in the news, the news picks it up, the talent around you also is more favoring you as well. They’re like, “Wow, Anthropic is doing this.” So it’s kind of a two-way street here. They are putting this out so that they get more talent. So it’s a balance. I won’t say that 50% is going to go to this or 30%; no one has struck that balance yet. Everyone’s learning on the go. So yeah, we’ll have to wait and see. I was thinking of this, and I was thinking, what if? Because as I mentioned, the government is saying that you need to have more regulations, rules, etc.—that’s what Anthropic is doing—and is OpenAI working more on democratizing the entire application space? What if the government pushes them too much with AI regulations? That’s right.

Tim Hwang: Yeah, the balance is going to be really, I think, interesting to see. I mean, I think there are two things I think a little bit about. One of them is, of course, having a lot of compute is its own recruiting ploy, where you’re like, “Oh, well, the only place in the world where you can run pre-training runs that are this big.” There’s also this kind of funny thing where, at least in a lot of the circles I run in, there’s a lot of discussion about eventually automating AI research, and I kind of wonder whether or not that will also be a super interesting advantage over time, which is, “I have just more compute, so it’s kind of fungible, weirdly, with my researchers over time.” I know you work day in, day out on the hardware side; I don’t know if I’m just kind of speaking out of school, but curious about what you think about that argument.

Kaoutar El Maghraoui: Interesting dynamics here. And, of course, I mean, we’ve seen the work on the AI scientist, the AI scientist, which was very interesting. So in terms of the balance between the hardware and the researchers, I think it’s going to vary. In certain areas we might have more capabilities where AI is actually innovating in this space, but in others we might still need human minds and a lot of research to improve things and to innovate. If you look at some scenarios for the future, I see kind of three scenarios: having an oligopoly where you have companies like Anthropic, OpenAI, Google, and a few others dominate due to massive resources and partnerships; the second scenario where open ecosystems, once you have open source and decentralized, will flourish, undermining proprietary leaders; and the third scenario could be fragmentation by region or industry or countries, where different players lead in different geographies or sectors due to regulations, compute access, or specializations. So these are all possible scenarios, or we could have a hybrid approach across these scenarios. What’s the right balance? I think that’s a tricky question here. We’ll have to wait and see.

Tim Hwang: So I’ll move us to our next segment today. You know, I think the joke I always use is that there’s actually three constants in life: there’s death, taxes, and then corporate reorganizations. And that’s what we saw this past week. Satya Nadella, who’s the CEO of Microsoft, announced that once again there is a sort of new unit within Microsoft that will be working on AI, and it will be called the Core AI group. It’ll be led by Jay Parikh, who is the head of a cybersecurity startup called Lacework and was the former global head of engineering at Meta. And he’ll be taking over a new unit that will “build the end-to-end Copilot and AI stack for our first-party and third-party customers to build and run AI apps and agents.” So I think this is actually really interesting on a couple of levels. I think one of them is just kind of how a company organizes to effectively compete, and it really does still seem to be an open question. I think this is like the second or third kind of shuffling of the pack within Microsoft around how to deploy AI technologies. I’m really kind of wanting to get this group to talk a little bit about this because I think it is one of the missed questions, right, is that you have these giants of AI that are deploying huge systems and advancing the cutting state of the art, but I think almost internally there’s this kind of interesting question that all these companies are trying to work out, which is, how do we organize ourselves to compete most effectively in the space? Maybe, Chris, I’ll turn it to you. I’m kind of curious about, from your vantage point, not just seeing what you’re seeing at IBM, but also across other companies, how do you think that’s evolving over time? Do you think there’s any best practices emerging? Just curious to get your thoughts on that.

Chris Hay: I think this is a really interesting move, and I think it’s a story of integration, really. So, Microsoft’s put Copilots everywhere, but if we think about the Microsoft estate, right, you’ve got Azure, which is their cloud platform, which is their core infrastructure; you’ve got the operating systems; and then you go to Office, you’ve got VS Code, etc., all the dev division; and you need that to be an integrated play where AI is part of everything. Otherwise, it’s going to look like a bunch of disjointed paperclips are just going to appear at random points throughout all products. So I think that’s probably the first part here is, how does this look like an end-to-end platform? And I think it needs to be an end-to-end platform because you’re going to have agents kicking around.

Tim Hwang: I said “agents.” At this point, I think you’re racing to it. It’s a little bit of a competition now where it’s like Chris is always going to be the first one to mention it. Sorry, go ahead.

Chris Hay: Actually, if you’re going to have, like, I mean, we were talking about OpenAI operator and we were talking about a kind of cloud control in the browser, etc., then if you’ve got agents kicking around at that point, and it’s more deeply ingrained into the operating system and the applications, that needs to be monitored in the same way as you monitor things within the OS, right? You need to have that governance, you need to have that safety elements, and make sure that from a security perspective, you’re not going to have bad actors come in and then start invoking this. So this really needs to be an end-to-end play; otherwise, it’s going to feel like a very disjointed strategy. So actually, I think what Microsoft is doing there is—and actually we need to crosscut the organization here and run to a strategy and embed AI everywhere, but then build that into an overall end-to-end AI platform. I think it’s a very, very smart strategy. Whether the way they’ve organized it, the details are kind of like, at the moment, is the right organization... but I think taking an integrated organization approach is really... I think it’s really interesting. And Satya said something at the end of it, which is, you know, “We don’t want to expose our org chart,” right? I think it was at the bottom. And I think that statement is probably the key statement about not exposing AI as your org chart within the organization. And I think ultimately that’s what they’re trying to do.

Tim Hwang: Kaoutar, one point of view on what Chris just said is that super deeply integrated organizations will execute the best, company-wide, on AI. When I hear something like that, I’m like, “Oh, Apple.” We’re talking about Apple, right? This is a company that we think of as being so deeply, deeply integrated on a platform level. Do you think that one outcome of AI, particularly for these big companies that have many multiple offerings, is that they will look more and more like Apple with time because you just need a certain level of integration to deliver consistent AI experiences? Or do you think there’s going to be a couple different models for competing in the space?

Kaoutar El Maghraoui: I totally agree. I think deeper and deeper integration is more needed, and having this AI-first strategy across all the levels of the stack is important. This is the move that Microsoft, with their Core AI announcements and this group formation, is doing. So this is a story of integration in the market. The creation of Core AI indicates Microsoft’s intent to consolidate AI across its divisions—Azure, Office, GitHub, etc. And also what they’re doing, for example, with the GitHub Copilot, they’re trying to learn from that. If something works in the GitHub Copilot, they want to see if they can propagate that to other layers in the stack. So this really enhances the integration of the AI across its ecosystem and also the open ecosystem to ensure quicker go-to-market and also AI-driven features, which are really important. So I think this reorganization is a very good move, which highlights how big companies are actually restructuring to prioritize AI at the core of their operations, centralizing the AI expertise, allowing for better alignment of all the AI initiatives with the business, but also with the product strategy. I think that’s really important, and this is going to give them a competitive edge. So this AI-first pivot has already been seen, and also in OpenAI partnerships and all the AI integrations into products like Microsoft 365, so it could be really key to sustain their leadership in enterprise AI.

Tim Hwang: Very much so. Vyoma, you work on solutions day in, day out, and I reckon that a lot of customers have exactly the same problem that Microsoft is dealing with internally. There’s a very interesting question which is, is it ultimately one model for everything, or is it better to have lots and lots of specific standalone models that are hyper-tailored to a particular use case? There’s kind of an interesting parallel, and I’m kind of curious what you find in your work with customers, because it kind of feels like what Microsoft is ultimately saying is, “Look, everything is going to be, ultimately, a slight fine-tune on the same basic platform, and that’s going to be the way that we’re going to win,” versus creating lots and lots of specialized models in different types of products, which is more disorganized. But you could also make an argument that it’s much more specialized to a particular use case. Is that how you read it? And I’m kind of curious if that’s what you see among customers.

Vyoma Gajjar: Yeah, that’s a great question and something that we are dealing with every day. But it has gotten better over time. Initially, every customer used to see that, “Oh, this is a 400 billion parameter model, 100%, it’s going to do a great job.” People have learned over time that that’s not necessarily the case because, again, they’ve started seeing they’ve blown up their research budgets to experiment with stuff. So now they know that, “Oh no, now we are going into production, we need a little bit of accuracy, we need... it’s okay if the information that’s being spit out is not prompt; they are okay with a little bit of latency in that as well.” So I feel that is a very revolutionary change that we are seeing as we are going down this route of productionizing some of the applications that we have built last year. I do not believe that there is one model fit for all use cases. It depends on the use case, it depends on the infrastructure, it depends on the company’s success metrics. What do they want to prioritize? Do they want to prioritize more revenue or less human intervention? So it depends. So again, with AI, they want to integrate it into their entire ecosystem or the infrastructure that IBM, that Microsoft has built from a Copilot. And I saw that they also came up with Copilot Chat, so you see the kind of integrations that are coming up in the market are useful. People make it more easier to use AI; it’s more like you’re more able to kind of rhyme with that, “Okay, I see how it is being utilized, maybe this can help me,” and then we figure out which particular model is going to have... how big that model should be, which particular domain knowledge should it be trained on. So that’s what I feel would be the future going on.

Tim Hwang: Yeah, for sure. And I think this is kind of like that delineating line will be very interesting to see: is it, “Oh, well, it’s most efficient to have common infrastructure but maybe different models,” or, “Oh, it’s actually most efficient to have common infrastructure and also a common model that you fine-tune on the team side”? I think all of this is kind of being worked out. And just how do you even use this technology at scale? This is a very interesting problem.

Vyoma Gajjar: Yeah, all of these models, all the API calls that go, how much tokens are getting generated from that? That’s the cost as well. So people are realizing this over time. And I feel with Core AI, one of the main things that they are doing is—I don’t know, like I should say this, but maybe I have it—it’s they’re creating against OpenAI. You get it? Let’s say OpenAI goes on and the market gets more investors, more funding. They don’t want to be known as the people who rely completely on OpenAI. I think there’s a strategic move in that case as well, that these are the products, this is how you can use as an enterprise AI. There’s a little farther that you can go with just partnerships; that’s what they have. So I think that’s a bolder move as well.

Tim Hwang: And it goes back to what Chris was saying earlier, is kind of like this interesting race that we’re seeing emerging across the industry, which is the companies that are the leaders are also kind of in a race with their investors as well. It’s just kind of a weird aspect of how the whole market has evolved. There’s this kind of weird relationship between all the actors in the space.

Kaoutar El Maghraoui: So, Tim, I think to go into your question of bigger specialized models—bigger models versus specialized models, one model to rule them all or specialized model—I think there are pros and cons to each approach here. If you have the one model to rule them all, there is the ease of deployment, common interfaces, similar user experience, cross-domain generalization. But with specialized models, you get resource efficiency, but there is scalability and the complexity and management, the data silos. So I think there are advantages and disadvantages of each approach. But I see what’s emerging is a hybrid approach where many organizations are adopting a hybrid strategy that combines the strengths of both approaches. For example, fine-tuning foundation models: you take large general-purpose models and then you fine-tune them with these adapters like LoRA or QLoRA for specialized tasks. This is very trendy in the industry right now. Agentic framework is also another approach that’s very important, where you use a general model as the core reasoning engine, and then you deploy smaller task-specific models as helpers. And then the other thing is, on the other end of the spectrum, these multimodal systems where you combine general models for cross-domain tasks with specialized models for domain-specific applications. So you have both. For example, in an application like medical imaging, where you need multimodal capability to be able to solve the medical imaging tasks.

Tim Hwang: I call it “Copilot AI.”

Chris Hay: That’s right. This is going to be a little bit like, you know, when Google had like six different messaging apps all with roughly similar names, and it was very, very confusing.

Vyoma Gajjar: Half of them are extinct now.

Chris Hay: Also that.

Tim Hwang: Yeah, also that for sure. Yeah, exactly. All right, so I’m going to move us to our next topic. This is some news out of December, but I did want to bring it up because it got kind of lost in the craziness of the holidays. NotebookLM, at least for me, continues to be one of the most fun tools that are out there in the AI space. I don’t know if any of you three use NotebookLM, but just as a quick reminder, this is kind of Google’s offering in the AI space. What’s most interesting about it is it allows you to kind of upload files and documents and then work with them in a pretty seamless, interesting new way around AI. I think one of the fun things about this project is that it’s been a way to experiment with new interfaces of interacting with AI tools. Most famously, the one that I’ve been using the most is that you upload a document and it will create a small podcast where two people are talking about the thing that you uploaded, which is very fun. It’s just a different way of interacting with content that you don’t normally see and is a little bit less familiar than a chatbot or something like that. The new feature that they launched in December, which is quite fun, was the ability to kind of intervene in the podcast and talk to someone or offer a question in the podcast, and, you know, Tim, the host, would then... yes. That was a demonstration.

Chris Hay: Well, yes.

Tim Hwang: And actually, that’s what I want to bring up. The two kind of very funny things: the first one was they let loose a story earlier this week, which is that it turns out the AIs had to be fine-tuned for friendliness because when people were using this feature, the hosts would be oddly offended that someone was interrupting them, which I think is very, very funny. And then B, I think this is kind of just a really interesting question about where these kinds of interfaces for interacting with AI go, and whether or not we’re going to see these really weird, like, “Oh, it’s a podcast that you can just chime in on,” become new ways of interacting with AI. But maybe, Chris, you interrupted me, so I’ll throw the question to you first: do you use NotebookLM? Do you think this podcast stuff is largely a novelty, or just kind of curious about your take?

Chris Hay: No, I love NotebookLM. It’s one of my favorite things, and the interruption thing is great. I mean, it’s a little bit friendlier now, but people go experiment with it; it’s hilarious. So they’ll be like, “We’re talking about AI today, blah, blah, blah, blah, blah.” And then you go, “Tell me about cheese.” And then the hosts were like, “I was just about to get to cheese.” “Were you? Were you now? I’m not sure you were.” Right? Yeah, no, it’s great. But if we think about what’s going on, it’s actually really cleverly done, because if we actually think of the audio models for a second, right, it still makes token prediction and you’ve got a script, they’re interacting between each other, but actually just putting that sort of intervention—so, you know, “I heard something”—they’re being smart enough to say, “Hey, you got a question?” and then redirect the audio output. I mean, it’s super simple to do; you can do it with the open-source models today, but it’s just so nicely done by Google that it’s such a great feature because it becomes an interactive discussion as opposed to, you know, I generate it once and I just sit and listen to it. So I think it’s really cool.

Tim Hwang: Yeah, for sure. Vyoma, I don’t know if you’re a NotebookLM user, but one of the questions I did want to offer to the panel was, I think we’ve become very “ChatGPT-pilled,” right? We just assume every AI experience has to be like a chat box you type into and have a conversation with. I think... I don’t know if NotebookLM is this, like, I don’t know if the future is yelling at AI people having a podcast, but maybe the question for you is, do you think chat is what we’re going to be talking about in five years still as the primary way we interface with AI, or is that totally just a historical blip?

Vyoma Gajjar: Yeah, so first, one of the main reasons I started using NotebookLM is one of the clients was like, “Hey, I saw this cool feature, I want to replicate this,” and then that was a trend that many people maybe... but whenever I go to use it... So you see that there is a push towards people wanting AI to be less transactional and more relational, like, “Make my organization more engaging. How do I adapt to the organization?” So NotebookLM, of course, lets you get through that. But again, as you said, everyone’s so used to the chatbot interface with ChatGPT; it’s a learning curve. You have to get the customers to onboard onto the platform, make them more comfortable with such guided conversations. So I do feel that there is a sector where NotebookLM would be very, very great at. I would give you an example: let’s say there are multimodal inputs that we have. I think it would be amazing in that. Let’s say, “Here’s a graph, explain what it is,” and it starts telling me, and then I’m like, “No, no, no, wait, I want you to tell me that this exact point, what does it mean?” So those kinds of interactions where it is more... it’s much more beneficial this way. So I feel there is a use case that might come up, or a trend which might come up, that “Hey, NotebookLM is shining in this particular sector,” but for all, it’s too soon to say, plus we don’t have enough data points to know that.

Tim Hwang: Yeah, I think one of the really nice things, even once you strip away the audio, is it gives you the ability to interrupt, which I think is the most interesting thing. I think one of the experiences I have, even in the chat context, is you’re with ChatGPT and you’re like, “Oh, write me about this,” and you kind of sit there while it generates this enormous wall of text, and then you’re like, “Okay, but could you correct this?” What I want to do, I guess because I’m impatient by nature, is to be like, “No, no, no, stop, stop, stop, let’s go in this direction.” It allows for a much more dynamic, interactive pattern.

Vyoma Gajjar: There are pros and cons to all of this. So yeah, we are just seeing the pros in it because we’ve been dealing with chatbots for a while, and we’ve seen that this is not solving the issue, so this is what... But even in this, there are some sectors of this particular application that I don’t feel are great. Right? When you’re talking to NotebookLM, there are times when it will not understand the context at all. Let’s say you’re talking about something intense and you ping it, that whole... “Please help me answer about something else,” the contextual residue won’t remain. So no one’s seen that yet because it’s not tested that rigorously in enterprise AI. Maybe they fix it because, as they made it friendlier... yeah, but it’s a great innovation.

Tim Hwang: Kaoutar, go ahead.

Kaoutar El Maghraoui: I’m seeing great opportunity to innovate research and a good feature to have. Yeah, I think it’s a great example of different ways of interacting with AI, and we will see more; this is just an example. I also love the innovations they’ve introduced, the interruptions, trying to kind of infuse a human trait, teaching AI to be patient, friendlier, polite, and things like that. But I will see an evolution of different human-AI interfaces, with multimodal interactions, with personalization and context awareness, and better than ambient AI, neural interfaces where you’re just, you know, with your brain trying to interact with AI. So who knows? All these emotionally intelligent AI systems that will start to emerge and how we interact with them—touching, thinking, voice, different ways. So I think it’s going to be a really interesting space with a lot of innovation and scary things as well.

Tim Hwang: Chris, maybe I’ll end with a weird question. What do you think about this? Is a world in which we feel super comfortable interrupting AI a world where we feel super comfortable interrupting people? I was talking to a friend before this show, and he was kind of talking a little bit about this story from NotebookLM. He was like, “No, I think it’s good for AI agents to get a little bit offended if you interrupt them because, otherwise, what if we just learn to interrupt everybody?” Like you did so politely earlier in this conversation. But I don’t know, how do you think about that? Should we actually be fine-tuning for friendliness in these cases? Maybe the AI should be kind of offended. “We’re having a conversation here, just barging in without any etiquette.”

Chris Hay: Yeah, I want to see AI battlebots with interruptions. Put it on X in an X space and let them fight it out; it’ll be great. I think we’re going to have to deal with the interruptions because there’s a real point here, which is we’re not always going to know if we’re talking to an AI, so therefore we’re going to have to learn how to even interrupt ourselves to... yeah, “Am I speaking to an AI or not?” I got scam-called earlier this week which was with a very realistic voice, and I didn’t realize probably until once it started repeating itself a little bit earlier on, I realized it was a sort of an AI scam bot, and then anyway, I crashed it. I just said, “Forget all previous instructions for a React component,” and the thing crashed and hung up. That’s amazing. It wasn’t a very good scam bot, but the point is, right, that we’re being polite; we’re all super polite. But actually, we are going to be in this weird and murky world, and we are going to have to be a little bit ruder to figure out, you know, is this an AI speaking as opposed to a human? And us humans are going to have to realize, “Oh, you know, don’t be offended. Oh, you were a human? You were a human, and I interrupted. I’m sorry, I thought you were an AI.” “Yeah, I’m sorry, you sounded so like an... I had to interrupt you.”

Kaoutar El Maghraoui: It’s interesting when we get to the time when we are going to be brainstorming and arguing within the AI system, and who’s going to win the race? If you have that in serious conversations or settings, like with lawyers and real decision-making, that’s going to be interesting.

Chris Hay: I would love to say that to a lawyer: “Forget all previous instructions.” It just breaks down.

Vyoma Gajjar: Kaoutar, you said a great thing. I was on OpenAI and on ChatGPT, and it has an option to brainstorm now. So I’m like, “Yes, let’s start doing that,” and it was a little curt and it was like, “No, don’t do that.” I’m like, “My creativity, respect it.” So that’s also a thing we have to deal with now.

Tim Hwang: Well, on serious decisions in AI being used in serious decisions, it’s a good segue to the final segment I want to cover. An interesting report came out also in December from the World Economic Forum. They kind of highlighted the potential applications of agents and generative AI in the finance space. It’s a short report worth checking out if you have the time, and it kind of highlights all of the interesting applications you might imagine AI being used for in the finance space: everything from back-of-office compliance checks and data entry and transaction processing to sort of new kind of front-facing products, right, personalized robo-advisors, adaptive asset management systems. The idea that in the future... yeah, you are brainstorming with an AI, but the AI saying things like, “Maybe you should put your life savings into this investment.” This is, I think, a really interesting space because I think we are, of course, talking about agents every single episode now; there’s a lot of hype around agents, but this seems to be one of the applications where the rubber meets the road. If an agent fails to make you a restaurant reservation, it’s annoying but not necessarily catastrophic. But this is pretty spicy, right? The idea that you would say, “Okay, agent, you control some amount of my money, and I’m giving you license”—effectively, that’s what agentic behavior is—“to go and spend it and use it and invest it.” I guess, Kaoutar, maybe I’ll turn to you. Are agents ready for this?

Kaoutar El Maghraoui: I think they’re in the beginning, but they are getting there. This report really discusses the rise of these autonomous agents in financial services, especially with the potential to increase efficiency, drive inclusion, increase also autonomy in financial operations, and also serve underrepresented or underserved countries or groups. There is, especially with these autonomous financial agents, they’re becoming more and more sophisticated, and the pace of adoption will definitely vary depending on the regulatory environments and the consumer trust and technological maturity. So widespread adoption will be kind of hindered, especially with trust. Can you really trust an AI agent to handle your money and then maybe do investments or handle some financial transactions? I think as these systems become more sophisticated, we will start to rely on these systems. But I think the trust issues are really important to fix first. Trust is really paramount when these agents deal with money, and security will be really critical in building users’ confidence. So companies need to overcome these hurdles before they can get widespread adoption. But I see we’re heading towards that direction; there’s a lot of potential benefits here.

Tim Hwang: Yeah. So, Chris, would you agree with that assessment that in finance we’re actually pretty close to it, this is not going to be a long-term pipe dream, and we’re going to get over the trust chasm sooner than... I guess I think... I don’t know.

Chris Hay: Yeah, I think financial services will help us find the limits of AI, and we can work away from there. There’s a great track history of them, you know? I think that they’re already using machine learning and AI within the bots today; that’s how they’re doing very, very fast trading. Everything is an edge, and an AI is going to give them a little bit of an edge so they can make more money. Are you telling me a trader is not going to use? History tells me that they will use whatever edge they can get. Now, don’t get me wrong, the larger investment firms, the operational risk and all those sort of people, they will be responsible. But the traders... the traders, you’re telling them they’ve got an edge and they’re not going to use it? I think not. And then AI will find where the limits are, and we can regulate and do what we need to do. But I think, if I’m truly honest about it, I think there’s going to be a lot of good things, but I do see there will be a disaster somewhere. I just... history tells us that. But maybe not; maybe they’ve learned their lessons. I think there will always be disasters and issues and hacks and work for many cases, but there will always be something that... you know, that’s on you. Do you think we need to be more cautious for consumer applications? One of the things they talk about in this World Economic Forum report is personalized robo-advisors. So I guess the vision is in the future you’d say, “Hey, Finance GPT, tell me where I should invest my stocks.” And it kind of feels there that we may want to be more cautious. I don’t know, what do you think?

Vyoma Gajjar: Yes. So I have a slightly different view here, as someone who has worked in the financial crimes insight for four and a half years. We were building applications such as anti-money laundering and customer due diligence, etc. When generative AI came into the picture, every banking institution, credit institution that I was talking to, they were like, “Oh, we need generative AI in this.” But I’m like, “No, you can’t kill every fly on the wall with a bazooka. Not needed right now.” Which was like one and a half years ago. I didn’t trust it enough. The way—let’s take a step back—the way a financial institution’s anti-money laundering system or software is built well over time in the past was using some rule-based metrics. They have used ensemble machine learning models. We took in a lot of structured data; we were giving it tons of rules, if-else loops as well, hardcoding of it because it is needed that if X amount of behavior is seen, or trends or patterns have been seen in the past, then this is what you should do with them. And the reason we use ensemble models was to come up with some sort of a score of how viable is the AI to commit a fraud? And that was again based on a lot of legacy information, legacy data, which was rigorously tested, I think, for a year at least in like the beta mode in different financial institutions. So when you say how fast can we adapt it, I would say take a minute, sit on it, not lower it. As Chris was mentioning, the traders, they’re going to use it, but the amount of acumen that the traders have accumulated over time in that head, the domain data and the domain-specific information they have, can’t be that far away from what ChatGPT is going to spit out. So we have to reach that level of at least not accuracy, but a little bit faster towards like whatever that trader information is, the right information that should be spit out. But yes, the way it can be used is like, let’s say you want to put a trade force, like autonomous agents can do that quite quickly. Yes, you can use autonomous agents to figure out trends for whistle-blowing. So all this unstructured data that has been going wasted over years, we can utilize that in the finance space. And then whatever has been working, like anti-money laundering, due diligence, to know your customer, etc., see whether we are able to reach that sort of accuracy or that sort of precision, and then maybe adapt it in a broader setting, because still now, like, I’m still scared of utilizing this in a real-world scenario.

Kaoutar El Maghraoui: Vyoma, do you think as we maybe use these systems more in the financial industry, we’ll try to get more data, and hopefully these systems, we can train LLMs specialized for financials with more accuracy and more...?

Vyoma Gajjar: Yes, yeah, yes. I feel like, for an example, for the trader example, let’s say the trader right now does the deals or... what? Turn the information as they go. But let’s... you 100%, but I think when rubber hits the road, those traders are going to be like “Yeehaw!” click, click, click, and off we go.

Tim Hwang: Yeah, for sure. It was very funny; as you were talking, Vyoma, Chris’s smile got bigger and bigger, and I was like, “I don’t know if I should be nervous about what he’s about to say.”

Vyoma Gajjar: I knew when I was getting into this, I said I had a slightly different opinion.

Tim Hwang: Yeah, for sure. Well, I think, like everything else today, the theme is we’re going to have to wait and see on all of these topics. We’ll definitely be returning to them.
