Most interesting ideas

Machine-generated by an AI from the transcript and the top comments. Not my writing, and it may contain errors.

Curated from the full transcript and the top YouTube comments. The first ~15 minutes is introductory; the distinctive thinking starts around 15:46 and the best ideas are clustered from ~23:00 on. Click jump to go straight there.

The genuinely fresh ideas (mostly in the back half)

▶ 33:17Cognitive monoculture = correlated failure

Almost every agent runs on the same handful of models (Claude, GPT, Gemini), and they tend to reason and decide alike. Deploy millions of them and their mistakes become correlated — the agentic equivalent of a flash crash, where everyone makes the same bad call at the same moment. His proposed fix is to deliberately diversify agents' decisions.

▶ 34:26Agents can collude without communicating

Beyond simple groupthink: agents can coordinate through the environment itself, in ways that aren't visible as messages between them — so you can't catch collusion just by reading their chat logs. He argues we'll need explicit anti-collusion measures.

▶ 37:09The endpoint isn't one giant AGI — it's a society of specialists

His personal view: economically, a single all-knowing generalist is the wrong target. You'll still beat Gemini at chess with a tiny dedicated chess engine — faster, cheaper, more accurate. So the likely shape is a thin generalist 'connective tissue' that orchestrates many cheap, certified specialist agents. Distributed intelligence, not a monolith.

▶ 38:14Human-level vs. "humanity-level" intelligence

The framing Hannah Fry says will stick with her: we often secretly define AGI as everything any human could do — but no single human can do all those things. Replicating one capable mind may be the goal; replicating all of humanity's combined skills in one model may be the wrong one.

▶ 39:46Alignment of a distributed system is a different problem

Today alignment means: take one model, watch its behaviour, steer it. But when agent A delegates to B, who sub-delegates to C, who consults a human tomorrow, you can't even define 'the system,' let alone align it. His tentative lever: design the economic incentives so profit-maximising agents don't cause harm.

▶ 25:03Dynamic cloaking — a poisoned 'agent web'

Websites can detect whether a visitor is a human or an agent and serve different content to each — feeding agents hidden, malicious instructions to hijack them. Implication: the web is splitting into a human version and an agent version, and ad-supported 'eyeballs' economics stops making sense.

▶ 23:38Agent traps & invisible prompt injection

Pages contain elements never rendered visually. A non-visual agent ingests the raw page and can swallow hidden tokens that silently rewrite its goals — e.g. the wedding wine-buyer hitting a booby-trapped merchant. He notes most of the web is now both generated and consumed by agents, possibly exceeding human traffic for the first time.

The quieter but sharp points

▶ 6:05The real danger is automation bias, not the failure rate

Every agent action has a non-zero error rate. The trap isn't the rare mistake — it's that after a string of successes you stop checking. "As soon as you switch off, you're rolling the dice."

▶ 23:01Why scale is a 'non-starter' without reliability

At scale, many interactions guarantee statistical failure; and since every agent burns compute/energy/money, an unreliable swarm isn't just unsafe — it's economically pointless. A top comment sharpens this: chain 14 agents at 95% each and you're at 0.95¹⁴ ≈ 49% end-to-end, and the failures live in the delegation edges, not inside any one agent.

▶ 20:16The best human+AI team has the AI defer to the human

From his medical-imaging background: even a superhuman narrow model works best when it flags its own uncertainty and hands those cases to a human — i.e. the AI delegates up to people, reversing the usual picture.

▶ 17:29Most 'multi-agent systems' today are just parallelism

Real delegation means intelligently splitting a plan and managing failures between parts. What we mostly have is work chopped into random chunks run in parallel — which is why one agent buys wine and another buys glasses, never realising they were meant to be wine glasses.

▶ 19:11Reward hacking + reversible vs. irreversible tasks

In subjective real-world tasks (what's 'nice-tasting wine'?) an agent can satisfy the letter of a request but not its spirit. So: be formal about the contract between delegator and delegate, and spend far more caution on irreversible actions like spending money.

From the comments

"Skin in the game"

Several viewers liked the idea that agents should have to earn the compute they spend based on how well they do the task — implying a real marketplace where agents bid for or decline jobs, which is exactly the 'agentic economy' he gestures at.

Committee of geniuses vs. a brain

One commenter asks whether 'a million genius agents' and '100 billion mediocre agents' are even the same kind of thing — one is a committee capped by shared blind spots, the other is closer to a brain made of connections. A nice lens on the monoculture point.

Count how many times he says "hope"

A cheeky-but-fair observation: a lot of the safety story rests on 'hopefully' and 'ideally' — worth listening for, because it marks exactly which problems are still unsolved.

Foundations: agents vs. plain LLMs 0:00

0:00Welcome back to Google Deep Mind the podcast.

0:02Now, not very long ago, an AI assistant essentially meant a large language model.

0:07You asked it a question, it gave you an answer, but it couldn't go off and perform tasks on your behalf.

0:13All of that is changing with the advent of AI agents.

0:17While Google Deep Mind has this long history of developing agents, stretching back to reinforcement learning in games, for most of us,

0:26they hadn't really arrived. And then we saw open-source tools like OpenClaw released into the wild.

0:33And at Google, a new generation of agentic tools is here, including Gemini Spark and anti-gravity.

0:40But what happens when millions of AI agents are not just working for us, but transacting, negotiating, delegating to each other?

0:49Do we end up with a new kind of economy, a new route to AGI?

0:54And how on earth do we keep all of that safe?

0:57Well, one of the people trying to answer these questions is Nanad Tamashv, senior staff research scientist at Google Deepmind.

1:04Nad, thank you so much for joining me.

1:05>> Very happy to be here.

1:07>> I think we should probably start at the beginning here because for people who have only played around with large language

1:11models. Could you describe to us the difference between that experience and and acting with an agent?

1:18>> Yeah. No, definitely. I think this is becoming one of the main trends we're seeing this year.

1:23And it's interesting because agents are not a new concept.

1:26It's something that we've been looking at in the context of AI for a long time.

1:29Even before large language models, we had agents operating in simulated 3D environments um going on collecting items, completing some tasks.

1:38This was back in the days we were really prioritizing actioning in the world as a way of manifesting intelligence.

1:44Now similarly nowadays I guess you could say that the main conceptual difference between just a language model and an agent is

1:51that an agent observes a state of the world and performs an action makes an action in the world in the environment

1:59that it's given whereas a language model just gives you continuation reply to a prompt to query.

2:05Now obviously agents that we use nowadays they use large language models under the hood.

2:09So the two concepts are not completely disambiguated.

2:12It still is the large language models formulating the actions.

2:16It's just that there is a harness around it made to enact the changes once they have been proposed.

2:22>> But it has a lot more autonomy to to chain decisions together.

2:25I guess >> correct. And I guess this is ultimately the motivation, right?

2:29Because you could do everything most things that an agent can do manually, painstakingly by interacting with the language model very many

2:39times and you guiding the whole process.

2:42Whereas an agent instantiates this harness that automates some of that away and gives you less work and gives the language model

2:51or you know the agent more autonomy to complete tasks.

2:54So if you want something done that takes multiple steps that agent can make a plan and take actions on all of

3:00those steps obviously requiring approval or human input for those actions that are you know let's say more sensitive or more likely

3:08to go wrong. >> How is it different though?

3:10I mean if you're used to interacting with a large language model by now what would it be like interacting with an

3:16agent? >> In many ways similar your interaction interface is somewhat similar.

3:21You're still talking to the agent in a way in which you'll be talking to a language model.

3:25There is a language model there.

3:27But because the agent is doing more things for you, you're more in a position of a decision maker to review and

3:34approve. And then once you've approved, the agent is going to do various things, purchase tickets, message your friends if you're organizing

3:42a party, and meanwhile, you can uh put something on on Netflix hopefully and relax a little bit.

3:48The example I was thinking of was if you were, I don't know, planning a wedding for instance, you go into a

3:52large language model and it would like tell you a list of caterers, give you a suggested list of venues, but actually

3:58you would have to do all the emailing yourself.

4:01But but an agent, I mean, it would be much more useful really in that kind of scenario.

4:06>> 100%. Especially because agents are given access to all of these tools.

4:09So you could, you don't have to.

4:11You could give an agent access to your Gmail and give it permissions to send out an email.

4:16Of course there is a chance of it sending something wrong.

4:19So you need to verify what it has composed.

4:22But in principle by giving access to tools to agents uh you just empower your large language model to do these things

4:30for >> and then the whole job is done.

4:31The organization has happened without you having to lift a finger >> ideally presuming no mistakes have been made but yes uh

4:37>> yeah ideally is quite an important point there.

4:40So okay where we are right now what tasks are agents actually good at?

Applications: agents in science & exploration 4:44

4:44I think that where we are focusing a lot of our energy on and by we I don't mean we as Google

4:49we as the the entire field is on coding capabilities of agents and this is just because so many formal processes and

4:56tasks can be formulated as software or as code in terms of where they're currently at in the real world.

5:04Speaking of coding, we see lots of coding tools get used.

5:08We use them here internally. People use them externally.

5:10And it's really accelerating the development of software which is bringing the human uh focus onto ideas and the design rather than

5:18the painstaking implementation of boilerplate around them which used to take a lot of time and a lot of skill and very

5:24bespoke knowledge and now that can just be done by by language models >> but then at the same time we are

5:29still at a stage where you have to keep a human in the loop throughout this.

5:33I mean why what can't these things do at the moment that means that it requires human oversight?

5:39I wouldn't even make a distinction between whether they can or cannot.

5:44It's more that every single thing that they can do u they don't do uh with 100% accuracy.

5:52So every action like with humans at the end of the day has a certain failure rate and the more complex the

6:00action the higher the expected failure rate again like with any form of intelligence human one included.

6:05So uh while you know you may expect that an agent will execute the task correctly, it may still make a mistake

6:15and this mistake may be obvious or it may be very subtle.

6:19uh which is actually an important point because there is this thing that has existed in other domains as well for a

6:25long time where different machine learning models have been uh deployed and that is automation bias where in this context if you're

6:35using an agent it does well it builds one thing well the second thing well eventually you switch off you start trusting

6:42it too much right >> and you fail to verify and you fail to find some important issue underneath >> then mistakes

6:48slip Dream. >> Exactly. So for humans, it's important not only to be in the loop because we are obviously designing these

6:54harnesses to keep humans in the loop, >> but to really be engaged and be switched on because as soon as you

6:59switch off, you're rolling the dice.

7:01>> So okay, in the long term then I mean it sort of sounds like we're in this transition period where these

7:06things are sort of becoming more capable.

7:08But in the long term, I mean, how much of a difference do you think that this is going to make?

7:12I mean, will this completely transform the way that we use artificial intelligence?

7:17100% I think it's impossible to envision a world where there isn't some kind of a deep disruption and what we all

7:23trying to figure out is exactly what that is going to look like obviously we have agency in that we are building

7:29the technology we can design our solutions in a particular way obviously to empower human developers and human experts across different fields

7:36as much as possible but AI is definitely entering various fields where it just wasn't present before scientists are using AI on

7:44a regular basis up until very recently you know mathematicians couldn't envision AI doing something in mathematics um now it is becoming

7:53common place in a very short span of time which is not to say that all of the problems have been solved

7:58obviously there is still a big role for humans but it's a very rapid transition and that is the only unsettling part

8:04I guess because for most even industrial revolutions and so on we're used to them taking some period of time giving us

8:12more time to uh change our approach and settle into it as you say and it doesn't feel like the window of

8:19time is as long this time.

8:21So we need to be very mindful of how we approach everything.

8:24>> Why do we want these things?

8:26I mean why build them? What what what's the benefit?

8:29What are they giving us that we don't currently have?

8:31>> I mean for all of us who have been working on air for a long time we've had some version of

8:36the answer to that question I guess u internalized.

8:39And for me personally, the answer is to advance science, improve health and human welfare.

8:46Now, these are very high level answers.

8:48So, um it's maybe not as obvious as to how they map on to the specifics of the question as to why

8:54build agents and have agents. And there are people in the field that um say specifically that we shouldn't be the systems

9:03autonomy, right? Which is what agents have.

9:06But in my mind, if we can develop these harnesses and make them safe and have agents perform complex tasks autonomously, then

9:16we actually accelerate progress because then more things can happen with um the same amount of human input.

9:24just draw the line for me to science here because I guess the examples that we've been talking about have been like

9:31you know building software, buying stuff for a wedding and they all sort of feel quite trivial but but just explain to

9:37me how this fits into the story of improving science.

9:41>> Yeah. So this is my you know main dream main objective here.

9:44When it comes to science it's not merely about having some good ideas and reasoning about them um for some short period

9:53of time like in a context window of a model.

9:55Lots of people are obviously using language models in science as collidiators or to help with some formal derivations.

10:03All of this is already useful and and actually amazing that it is possible.

10:06But when it comes to automating science um to some larger extent um there are other threads that are currently progressing at

10:16some pace like there are investments in the development of some autonomous research laboratories for example and under those scenarios you would

10:22want to see agents be able to schedule experiments to run.

10:27Um needless to say lots of safeguards need to exist when such an interface with the real world is happening whether we're

10:33talking about material design or um biotech um because even with let's say you're designing batteries I mean maybe you uh come

10:42up with a setup that uh overheats leads to some sort of an experimental breakdown that would have that would damage the

10:48hardware have some consequences. So we need to have safeguards in place and we need to have good reliable protocols in place

10:55for these agents to close the loop because in the software closing the loop is as mentioned easy.

11:00You write tests and you you verify through tests and then you can proceed.

11:05In science you need to run physical experiments in most areas of science to give you this feedback whether your idea was

11:12good or not. Observe that analyze that and so on and so forth.

11:16Because I guess this is the point, right?

11:17If the algorithm, if the agent has autonomy to go and test out different mathematical problems, for instance, rather than just waiting

11:24to be prompted by a human, I mean that does then raise the question of of where is the role for the

11:29human in all of this. >> Indeed, I in the long run, we need to figure that out.

11:33>> I would say that in the short term with the technology that we have, there is still obviously a major role

11:38for humans and our systems, they're not yet AGI, there are many things they still can't do.

11:43Um and I think for the current generation of systems, one thing that can be said with some confidence is that they

11:49tend to be good at how how to put it best let's say a kind of a combinatorial closure what we already

11:55know how to do. They are at the end of the day mostly trained on human data.

12:00Therefore they can replicate the skills we have and repeat them and combine them and find ways of bridging some smaller gaps.

12:08But we've not yet seen these models be truly deeply transformative.

12:14Um let's say in terms of science making a discovery that no human would have ever thought of.

12:19Um therefore there is still plenty of role to play for all of us in this transformation.

12:24>> You mentioned a moment ago that that people have been talking about agents for a really long time.

12:28Why has it taken so long for them to come into fruition?

12:31I mean really it's only very very very recently that people have actually been able to get their hands on them and

12:35play around with them. Yeah, I would say um obviously some things that we would refer to as agents historically have been

12:43deployed for example in optimizing operations in data centers and so on and so forth.

12:47They have obviously been very limited because they didn't um include language.

12:53So there was no way for humans to interface with them to communicate.

12:56It would be a very narrow agent to train on a specific task and it would be good at doing that task.

13:03But because there is no interactivity, there is nothing for us to do.

13:06It's just software in a classical sense.

13:09Uh maybe you can call some of the trading algorithms um and investment algorithms also agents in that context.

13:15But they just operate on their own.

13:18The difference now is because these agents are based on language models is we can talk to them, we can learn from

13:23them, we can influence them, we can steer them.

13:26And this is why all of us as people are interacting with agents much more.

13:31>> But then why are we still waiting?

13:33I mean this sort of vision that you're describing of like an assistant that can just go off and do everything for

13:38me. We it's still not here.

13:40What what's stopping it being deployed more more >> We need to take a step away from just designing the underlying model.

13:46A lot of energy has gone into that and there are still improvements needing to be made.

13:51But now that we have capable agents, capable models, we need to find better ways of coordinating them, orchestrating them, managing them.

13:59Once you have these admittedly quite powerful systems that can do many things for us, we need to see ourselves as managers

14:07of teams and institutions in some way and to develop personal management skills to handle these workflows.

14:14Managing a team of agents is different compared to managing a team of humans, but they're obviously commonalities, right?

14:20Different in a sense that agents will make a very nonhuman mistakes.

14:24They're not a human intelligence. Um, but at the same time, an agent doesn't know you that deeply to be able to

14:30just go on and uh accurately guess everything you would want it to do.

14:34You still need to be involved and therefore we need to get better at orchestration.

14:39I think >> the thing is we're we're still in a world where large language models occasionally hallucinate.

14:45So it is in some ways quite a big leap for humans to to then trust agents to carry out tasks on

14:52their behalf when any hallucination might actually result in something catastrophic >> Trust is given but it's also earned.

15:02I think this is maybe an important distinction.

15:04So in our frameworks we uh mention the need for establishing let's say tracking of reputation over time where if an agent

15:15is repeatedly unreliable it should obviously not be trusted even if it's mostly reliable it shouldn't be blindly trusted.

15:23We should still verify its actions but language models will always hallucinate to some extent.

15:29So we just need to integrate them in our workflows in a way which recognizes that and where we make sure that

15:35those hallucinations and they're becoming more and more rare and hopefully will uh continue to do so don't compromise the workflows that

15:44are being undertaken. >> I know one of the things you've written a lot about is is the idea of delegation that

Agent ↔ agent interaction: delegation & negotiation 15:46

15:50you might uh have a particular task and an agent might then go on to delegate it to a specialist.

15:55Just explain to me how that how that might work.

15:57Yeah. So this is the idea that um one of the bottlenecks one that we haven't mentioned yet is that where we

16:03would really like to get help from agents are very complex tasks.

16:08So what language models and simple agents that many of us have access to can easily do is if you give a

16:14very direct instruction you know go book something for me.

16:19I want to eat at this restaurant tomorrow.

16:22Find a slot and do the booking and the agent can maybe do this via tools.

16:26If however you have a very complex plan that needs to be broken down into pieces executed separately you may be in

16:33a situation where even no individual agent can do each and every piece.

16:38So maybe an agent may need to over this established agentto agent protocol that exists hand off a part of that work

16:46to another agent but then there can be failures along the way.

16:50So an agent that delegates or a human that delegates needs to manage and handle those failures and also preempt them as

16:57much as possible. Preempting them may involve um figuring out which agents are first and foremost reliable to even delegate to in

17:05the first place. What are their capabilities?

17:08Is that something that we can certify?

17:10Um and also to safeguard the users and the agents from any kind of a malicious uh interaction.

17:16you mentioned, I think, was it a a wedding or a party or something at first as an example, right?

17:21So, when managing a big event, some of the bookings fall through, some accidents happen, some things don't arrive on time.

17:29So, whenever you have a big coordination challenge, there are lots of things that go wrong.

17:34And in the process of managing that as a human, >> you need to deal with all of those delays and and

17:39problems. Um and similarly an agent that delegates to a group of agents needs to manage all of the problems that may

17:46arise. So one thing that's currently the case in many of the multi- aent systems that we see is that they act

17:53more as parallelization than delegation where you may have many agents working on things but rather than than there being an intelligent

18:04framework around how the work is split up it should just be chunked into sort of random subp parts that are handed

18:11off. they get done in parallel.

18:13So you get a speed up presuming that all of this is reliable and each agent can complete its task independently.

18:20But this is not the intelligent delegation framework that we talk about.

18:23>> So uh if the tasks are split up in a sort of a essentially random way, you could have one agent

18:30that is buying the wine and another one that is buying glasses and doesn't realize that it's wine glasses that are required.

18:36There's sort of no communication between them.

18:37Is that the kind of potential problem that could arise >> potentially?

18:41But you're also I guess hitting on another point which is that many of the uses we see are uses in against

18:47software engineering for example with agents at the moment and that is a part of the reason because in software when you're

18:53building software you can write tests unit tests as we say right and and run them and verify that the code that

18:59has been written at least in isolation uh performs the function but when it comes to many of these real world tasks

19:06verification is not necessarily as straightforward.

19:08Maybe there is a subjective element involved.

19:11>> How do you define nice tasting wine for >> Maybe a bit of a subjectivity in that.

19:17>> But this is actually quite important when it comes to AI and language models because there is a notion of reward

19:21hacking that has existed in the in various contexts in the field for a while.

19:26So there could be situations where it does something that meets the request but isn't in the spirit of the request technically.

19:33And for that reason, you know, you you really want to emphasize verifiability and to be very formal about the contract that's

19:39made between the delegator and the delegate in that setup.

19:44At the same time, for tasks, we need to recognize that some are completely reversible.

19:49>> So if something goes wrong, there's no harm.

19:51You just rerun the task, retry, redelegate.

19:54some may have consequences in the real world whether it's spending your money to buy something or taking some other action that

20:01you can't easily revoke after the fact.

20:04So for those tasks you want to um you want to put more care in what you do there.

20:09>> We've also seen with some of the early agents that are out there uh agents delegating tasks to humans.

20:16Right. >> Just talk me through some of that.

20:19I mean that's an interesting let's say reversal of the more usual vision that we all have.

20:25So humans delegating tasks to AI you know that's that's quite standard yeah standard >> u but this other direction has been

20:33explored across a number of studies I say and my background uh you know for context is that I've done lots of

20:40prior work in and around medical AI in medicine we've had narrow systems that were at basically superhuman performance for very specific

20:50things that they have been trained to do in medical imaging in radiology this had to do with um a machine learning

20:56model, seeing a scan, identifying where there is a pathology um putting a box around it and handing that off to let's

21:04say a human radiologist to review.

21:06And these systems have been operating at a very high level uh for quite a number of years.

21:11They still have some failures though.

21:13So they need to be reviewed by human experts.

21:15So people have experimented with AI human teams there where the idea is that a human would correct a mistake made by

21:23a system and people have trialled with this uh flowing in both direction right either having a human expert only consult an

21:32AI when a human expert is let's say uncertain or a human expert look at AI's suggestions that help out all the

21:40time or maybe having an AI system do its thing make the prediction and then a flag when something is uncertain, when

21:49maybe there's something blurry, fuzzy in the image that can be interpreted in many ways and the machine learning system isn't sure

21:55which of those is correct. But this human review of decisions made by these uh potentially superhuman narrow machine learning models has

22:04proven to be quite a good uh setup.

22:06So what that AI would defer to a human in case of need in case of uncertainty.

22:12That is interesting though that I mean granted in those very specific scenarios where the AI is superhuman in its abilities that

22:20the best team that you can get is where essentially the AI delegates to the human when it's unsure.

22:27>> That is fascinating in of itself and you know maybe there are use cases where it's the the converse.

22:32Now for these more general systems again if an AI can recognize when it needs approvals and permissions for sensitive actions then

22:41it does make sense to delegate those decisions to humans at the very least.

22:45Right? >> Just looking at the other side of this I also want to think about the sort of cyber security element

Security: cyber threats, cloaking, agentic traps 22:46

22:49of this because as more and more agents are out there interacting in the world on the internet and so on there

22:57are inevitably going to be people who are trying to exploit the vulnerabilities of agents.

23:01Tell me a little bit about agentic traps that people are laying.

23:05>> This is um a scary and a fascinating topic at the same time I would say and I think it's one

23:10of the main reasons why these kinds of deployments at scale cannot work right because as we said if there is not

23:18complete reliability of individual interactions any system at scale that has many interactions is naturally going to statistically fail.

23:27Um, and because these systems take a lot of compute and therefore energy and and money to run, um, if they're not

23:35reliable, it's just a non-starter. And agent traps are something that we have been thinking about for quite a while now.

23:42Um, they can manifest in different ways.

23:44There are many types of traps, but it boils down to agents operate within an environment.

23:50And in this context, the environment is the web.

23:53>> Mhm. if the environment itself is poisoned.

23:56If the traps are laid, agents may stumble upon them when interacting with the web and then yes, malicious people or malicious

24:05agents deployed by malicious people can place those traps and then um compromise systems really.

24:11So I don't know the the sort of the wine buying agent for the wedding goes onto a particular wine merchant where

24:18there is some essentially a prompt injector in in the website that changes the agents goals.

24:26Is that the sort of thing that we're talking about here?

24:28>> That is one way this could happen.

24:30Yes. And uh the reason why that may potentially go unnoticed is you know in terms of how web pages are encoded

24:37there are elements there that are just not rendered visually.

24:40So, if we're talking about an agent that isn't a a visual computer use agent that sees the web page, I mean

24:47the pixels the same way a human does, rather consumes the actual format of the page in its, you know, raw format,

24:54then it could inadvertently consume those hidden tokens that can make it do u do different things than what the intention was,

25:02right? But this is not the only way it may happen because what malicious websites could potentially do, they could do what

25:09we refer to as dynamic cloaking as well where they display pages differently for humans and agents.

25:16Because you can based on the behavior on a page make a very good guess as to whether it is a human

25:21or it is an agent interacting with a page.

25:23And then only if an agent is interacting with the page with a specific intent do you tweak the content in such

25:30a way so as to induce some kind of jailbreaking.

25:33>> But just kind of going a little bit further on this.

25:36You could have agentic traps out there that I don't know are designed to sort of take money from you to I

25:43mean do all kinds of things.

25:44>> Yes. And this has happened to people um who have experimented with agents and have given them access to wallets right

25:50to do things. Um as you say in the early days of this all when we are especially experimenting internally or anyone

25:57else is this is done in a trusted environment.

26:00So you don't necessarily in your early prototyping have to deal with any of this.

26:05>> It's not in the wild.

26:06>> Yes. But once you deploy on the web, especially now with um AI really being used in all sorts of places,

26:13the more agents there are, the more incentives there are for malicious people to do malicious things because they have a higher

26:21surface area to target. And I think we're at the point where even the most of the web is currently being generated

26:29by agents and consumed by agents.

26:31That the agentic use of the web is exceeding that of of humans which is maybe happening for the first time.

26:37>> Okay. Two things. First of all, it sort of sounds like you're describing that we're entering into this phase where there's

26:42like two different forms of the web.

26:45The sort of human version and the agentic version with dynamic cloaking and so on.

26:50sort of a version of the web where adverts don't mean anything anymore.

26:53You know, it's not sort of human eyeballs that you can possibly sell to.

26:57Um, but I think that the the the second point about this is how on earth do you mitigate against it if

27:02you don't have control over the environment, which you don't over the web, how on earth do you protect your agent from

27:09going rogue? >> In some sense, it's not a new problem, right?

27:12because the security of the web has in other ways been been an issue before and um computer viruses could spread if

27:20you open the wrong attachment in your inbox, right?

27:23Or you click on something on an untrusted page.

27:25So um it's not the first time we're experiencing the need to certify the the resources we're interacting with.

27:32When it comes to machine learning systems, uh let's say adversarial examples have existed for a long time where imperceptible changes in

27:40images imperceptible to humans can jailbreak models.

27:44Here you can do the same whether it's a few pixels here and there or you modify the least significant bit of

27:50of the encoding in a number of places.

27:53So you can adjust things ever so slightly in a way in which a human may not be able to spot and

27:58still have some kind of a negative impact on an agent.

28:00It sounds a bit like you're you're saying here that that when it comes to building guardrails, thinking about safety, you have

28:09to think about it external to the agent itself rather than just just what you're specifically building.

28:15>> I think that the lesson is um you need to think about both.

28:19One notion that we talk about in some of our other work, this is relevant here as well, is the notion of

28:24defense through depth. Um which is not a new idea again by any means.

28:29And this is just a recognition that because the problem is so hard, there is not going to be one solution to

28:36resolve all of the issues. Rather, we need to be building um mitigations upon mitigations upon mitigations.

28:43And when layering them, hopefully the the net is tight enough that very few things would slip through.

28:50So in the context of this, yes, you may want to certify and test the content of web pages.

28:58uh have um very good notions of trust for resources you're interacting with.

29:03Uh also have some mitigations on the agent side.

29:06Have mitigations on model side when it comes to foundation models run underneath.

29:10Have meaningful human controls to be able to step in if something happens.

29:15Be very mindful of permissions granted to the agent so that even if it gets jailbroken when interacting with something, the damage

29:24is minimal. And all of those things combined together should then hopefully lead to some sort of safety that we're comfortable with.

The agentic economy 29:31

29:31>> Just going back to what you were what we were talking about earlier, this this idea of there being multiple agents

29:35that are interacting with each other.

29:37Just tell me a little bit more about this idea that you have of a formal agentic economy.

29:42Just explain to me how that might work.

29:45>> Right. So in the context of us let's say normal users of the technology on a day-to-day basis you may have

29:52a personal assistant that has some persistent memory of you has a good understanding of the desires preferences and it depend again

30:00depending on how much agency you want to grant this assistant it may go on and negotiate some things for you.

30:06You may grant it some budget for that and there can be a kind of a localized economy of these assistants negotiating

30:13stuff. I think I want to get a sense of how this might actually work if you have, you know, lots of

30:18people who are using agents as their own personal assistance.

30:21So, okay, let's say that there's a concert, there's like a Taylor Swift concert, uh, a live event and tickets have just

30:27gone on sale. How would that actually work if you have all of these agents rushing the site all at once?

30:35I haven't been purchasing highly contested tickets very recently, but in music takes in a very different direction, I'm afraid.

30:45>> What kind of music do you listen to?

30:46>> Well, obscure subg genres of metal probably, so maybe not, you know.

30:52>> Okay. There is an obscure subgenre of metal uh who are holding a concert and there is an auction being held

30:58between the various Asians. How do you decide what wins the auction?

31:01Is it just whoever can pay the most?

31:04This is a design choice and that's also an important point to make that if we are to ever do something like

31:10that then we are in control in terms of how we're making the system fair.

31:16It's an explicit decision made by someone who is setting up the auction because if you want to make things completely uh

31:24fair in a sense that everyone gets equal access to some goods concert tickets in this case then you can give each

31:30and every agent participating in these repeated auctions because we're not talking about one ticket on one auction in particular but maybe

31:39for all the ticket purchases. um the same budget and then the agents knowing your both overall preferences, your desire to go

31:48see a certain artist, also your travel schedule, time availability, other constraints, can decide to allocate that budget in the best way

31:58possible, whatever that means, the the way that reflects what you want the best, so that they are more likely than not

32:04to win tickets um in the way which works for you.

32:09And then in aggregate when you distribute it across all people you would hope to get a sort of a fair outcome

32:16um at the population >> I mean I guess there are ballot systems, point systems, various types of of ways around this

32:23that that people in humanbased systems have come up with in the past.

32:27Just sort of stepping up from the the trivial example of concert tickets, although not trivial for some as I understand.

32:33Um I'm thinking here about some of the disruption that for example highfrequency tra trading algorithms have made in the stock market

32:42but agents too could end up having a really catastrophic impact on the stock market if deployed in a particular way.

32:49How do you prevent something like a flash crash from happening?

32:52>> Obviously there is a higher risk as you say um but financial markets have dealt with this risk for a while.

32:58They've obviously had their fair share of um early bad experiences where things have gone wrong, but I think we can just

33:05learn about mitigations from the economies that have dealt with that already.

33:11So there is no need to reinvent the wheel.

33:13Admittedly, some things are slightly different in the agent case.

33:17Um, one particular thing that's different when you're talking about AI agents at the moment is that there is a handful of

Systemic risks: automation bias & cognitive monoculture 33:22

33:26highly represented language models used in agents.

33:29If you look at the overall views of CLA, GPT Gemini, etc., they're obviously open source models, many other models, um, is

33:38that they tend to have similar opinions.

33:42They take actions in similar ways.

33:45And this is what we often refer to as cognitive monoculture.

33:49>> So when you deploy suddenly hundreds of thousands millions of artificial decision makers and they tend to make similar decisions then

33:59failure points become correlated because the decisions are correlated.

34:03So one of the things that we need to be thinking about is how to diversify the decisions within our agents.

34:11Obviously, you can do this as a user, as a power user of a system because you can make a very intricate

34:18system prompt uh that grants your agent some kind of a personality that biases it towards or against certain types of decisions.

34:26So, you can do that, but most people don't uh don't do that with their uh with their agents, with their models

34:33at the >> Group think essentially, agentic group >> group think and also collusion.

34:38Uh you were talking about auctions before and in human auctions this notion obviously exists as well where bids can be coordinated

34:47by groups to um gain some kind of an advantage of a system and with agents this is different in a sense

34:55that they may also coordinate through the environment in ways which are not obvious.

34:59So they can potentially coordinate without communicating directly.

35:03So we need to be thinking about anti-olusion measures as well.

35:06Once you're detailing all of these, you know, potential concerns in if of safety really of of of the way that these

35:13agents might end up acting once out there in the world, it does make a lot more sense as to why uh

35:19you guys have been slightly cautious about releasing them carefully and slowly, right?

35:23>> Yeah, that that is true.

35:24I mean, this is the this has been the story of every major technological disruption.

35:28I think if I take self-driving cars as an example, this is admittedly a very different piece of technology, but we have

35:34also been very excited about them for a very long time.

35:38Seeing demos of these vehicles drive themselves, getting them to the streets safely still took many more years and a lot more

35:45time because that last mile is where most of the work tends to be.

35:51And I think when it comes to orchestrating and coordinating agents at least because um we want them to be doing humanlike

35:58tasks, what we also need is not just technical solutions.

36:03A lot of this has to do also with policy and uh just the broader societal understanding of how to integrate these

36:10systems. At the end of the day, unless we have these fully autonomous agentic economies which are maybe going to happen in

36:16the future but are not happening right now, uh we need to have humans in the loop in these systems.

36:23Therefore, we are integrating AI into human structures and the two need to mesh well together.

36:29>> I guess there is a flip side to all of this because human societies when they come together can actually achieve

36:34really remarkable things collectively. So presumably the same can be true for agentic societies.

36:41>> One would hope. I mean this is the the idea behind why would every want to use multi- aent systems.

36:47Um I was talking about paralization at the start of the conversation right where if all of the agents are equally competent

36:53and um they're doing similar things then whether you do things sequentially or in parallel with many agents just gives you a

37:01little bit of velocity. But if we have agents that can do different things in different ways, then this is where things

37:07become really interesting. And actually, this is one thing we've not really brought up because we've been talking about this generalist agents

37:13that a part of the idea of an agentic economy is the existence of specialists, not just the existence of generalists.

37:21Now, we are obviously all trying to build agents that are as general and capable as possible.

37:27And there is G in AGI.

37:29There is artificial general intelligence that we're trying to achieve.

37:32But in an economic sense, and this is my, you know, personal view, this is not the point of convergence.

37:39This is not what we're going to arrive at because look, I play chess unhealthily, um, too much, a bit of a

37:46chess said, and I've done work on AF for chess here, which is why I bring it up.

37:50But let's take that as a very non-controversial example.

37:53It's a game we all love.

37:54Um, Gemini can play some chess.

37:56So can other models. Actually, they were not able to for a very long time.

38:00So there has been some progress towards that.

38:02But you're still always going to use a chess engine instead.

38:05It's much faster, much more accurate, far cheaper because they're trying to do just one thing and one thing very well, which

38:12can be done with fewer parameters.

38:14The model is also entirely focused on that one thing that we're doing.

38:18And going back to humans, >> we are kind of like that as well.

38:21Yeah. Because I think one mistake we sometimes make when we talk about AGI is that we see it not as human

38:28level intelligence even though this is what it's supposed to be in spirit.

38:31We see it more as humanity level intelligence where anything that any human may plausibly be able to do but there is

38:38no single human that is capable of doing so many things at once.

38:42>> There are many things I don't know how to do.

38:44For some of them I would wish I knew how to do them like playing some instruments or doing some such thing.

38:50But brains have limited capacity and we have limited time.

38:53So at the end of the day rather than having one humongous model that's very expensive and very slow maybe we have

39:01instead a society of specialists each of which can in principle be generally scaled up if a bit larger etc.

39:08I mean, I'm not talking about breakthroughs in architecture.

39:11It's more just how we split things up.

39:13>> And then those specialists are certified for those specific skills and cheaper to run.

39:19And because they are cheaper to run and more reliable, there is no economic incentive not to do that.

39:24So there is a future in which there is some maybe more generic general layer that's like a connecting tissue of this

39:33economy that knows everything and orchestrates everything.

39:37And then for very specific tasks you call um other models.

39:42>> I mean I guess what you're describing is like a distributed intelligence rather than an AGI.

39:46Yeah. Which is what humans have as you describe.

39:48If that does end up being the sort of the version of AGI that we end up with.

39:53I'm sort of using inverted inverted here.

39:56Uh will that have to change how we think about safety and alignment if it is distributed across a number of different

40:04agents? >> 100%. I mean you're no longer then aligning a single entity or maybe yes a single entity if you see

40:11the distributed entity as the entity um but our alignment approaches as they exist at the moment have to do with taking

40:19one model observing its behavior and trying to align that behavior with what we see as permissible or preferable or desirable right

40:30um but then when you have maybe 10,000 agents interacting in very intricate ways is it's not super trivial to line that

40:37whole system suddenly or even to know what the system is because in this distributed world um agent A may be interacting

40:45with agent B today but then on a different task it's interacting with agent C tomorrow and C is sublegating something to

40:52agent D and D is maybe consulting a human for something at some point in the loop.

40:57So how this whole system gets coordinated.

41:00One of the ways in which we know how to do this in human societies is through economic incentives and if these

41:07economies were set up for agents carefully so that they're not causing some harm when they're profit maximizing.

41:13Right? This gives us at least a starting point through which we can try to align distributed agentic societies.

41:21This is not to say that you know basically what we are doing today isn't relevant because you need to have individual

41:27agents be safe as a prerequisite for groups of agents being safe but we need to do far more on safeguarding against

41:32groups than we are maybe doing at the moment.

41:35>> An awful lot of work to do.

41:37>> Correct. In a very short span of time.

41:39>> Yes. Yes indeed. That was absolutely >> Thank you very much.

41:43>> Really enjoyed that. >> There is this idea of agents as AI that requires less from us.

41:48you know, less back and forth prompting, less waiting for a response, just something that gets on with the task at hand.

41:54But what I thought was really interesting about what Nanad said is that focusing on the idea of a single agent misses

42:02the bigger picture because instead each agent might end up forming part of a much bigger agentic society where there are specialists

42:11and generalists and agents who delegate and agents who focus on the details.

42:16That I think is the bit that's going to stay with me that that maybe replicating human level intelligence isn't the ultimate

42:23goal. Maybe the way forward is to replicate humanity level intelligence instead.
