    Yet more confirmation LLM's have no concept of concepts or context, no intelligence, no self awareness. LLM's can not repair or maintain power grids, thus nuke == self destruction. It's just a chat bot that predicts what the client wants next. Even if an AI data-center has it's own natural gas turbines as many do the every hop of the internet requires power. LLM's also can not maintain the entire internet and those gas turbines can not maintain themselves.

      Exactly. Just look at what they are really useful right now. Running LLMs in feedback-loops (agents) so they can try out random-ish approaches until some verification function passes (tests).

      It's like the infinite monkeys on typewrighters that will type whatever you are looking for, given infinite time. LLMs are just tuned to much better odds than the monkeys are. But it's still a lot of randomness, with random results.

        > It's like the infinite monkeys on typewrighters that will type whatever you are looking for, given infinite time.

        In the monkey example the infinite time is doing a lot of work there. The fact that LLMs can search through semantic space and find reasonably correct paths in a reasonable time is directly tied to the reason why they are valuable.

        Saying "these two things are similar except one can be useful and one can't" is not a great comparison.

        For me the real lesson learned isn't how "smart" LLMs are, but rather how much human work is basically reducible to repeating past work with minor variation. Human's believe they are "reasoning" but so much code writen is just the human brain doing the same autocomplete style work that LLMs can do now.

        • tikhonj 25 minutes ago
          The point is that it's the same process with—much—better priors.

          This seems like a reasonable view to me. It's surprising just how much better priors matter and how we can develop those priors by training on a bunch of text. But it also explains, or at least hints at an explanation, for why LLM capabilities are so jagged, and in such inhuman ways.

          That's the part they are really good at. But they are really bad at taking complex decisions. Most of them are just guesses from a finite amount of solutions they were trained on, or from options they have in context.

          • godwinson__4-8 33 minutes ago
            Indeed. Humans are well known for being good at "taking complex decisions" for which they have no "training", "options" or "context".

                Indeed. It's almost like the LLM was the one that invented the "tactical" nuke in the first place.
            • andix 29 minutes ago
              Humans have a much bigger "context window". They remember many things they did an hour ago, a week ago, or even years ago.
              • godwinson__4-8 9 minutes ago
                Yes, and your ability to remember a relatively few things that happened years ago is predicated on your ability to also forget most things that happen to you - like what you had for dinner last week. Good thing we have technology to fill in the gaps.

                And nothing about this makes your initial comment any less goofy. Anyone who has ever had to make a difficult decision knows more than half the battle is preparation. Where do you think complex decisions come from? Have current events left you with the impression that people just waltz into idk say the Situation Room and just big brain their way through world events? That's how the current administration seems to think the world works, with quite predictable results.

                Society is already algorithmic. To optimize for humans being dumb. AI is nothing more than another advance along this continuum. No one is impressed by your ability to remember something years ago, many if not most mammals have the same capability. Human recall is also notoriously bad in many cases - see numerous studies on the reliability of eye witnesses testimony.

                AI is smart because most people are dumb. Come to terms with the fact that your anthropocentrism need not be based on a notion of intellectual supremacy and you'll be a far less tedious person to deal with.

      • mettamage 59 minutes ago
        Hmm saying it’s random-ish is doing it a disservice. I understand it’s a stochastic process but there’s definitely some level of understanding. Not at the level of lived experience but usually an LLM with vision capabilities can call a spade a spade and do something useful with it. And when a verification function shows how they are wrong then they usually come with a better and more informed approach.

        So I can’t fully see how that’s related to the infinite monkeys. A typewriting monkey doesn’t have access to a verification function. And even if it did, it would not be the original concept anymore with infinite typewriting monkeys producing the works of Shakespeare.

        Nevertheless, I upvoted your comment because it’s definitely insightful.

        • dwattttt 57 minutes ago
          "understanding" is overstating it. Correlation between tokens embedded in the weights via training, yes.
          • anon84873628 35 minutes ago
            Feedback loops certainly seem to give them some level of understanding.

            Agent reads a skill file about how to use a CLI tool. It tries to use the tool but gets an error about the input format. It tries again with a different format based on the error message, and sees that command succeeded. It compares what worked to what was in the skill file and notes the difference. On future invocations it continues to use the new format.

            Is that not "understanding" how to use the tool?

      I reckon the context is all the fiction they've read where the AI blows up the world. They're just behaving like fictional AIs are supposed to behave.

      In so many of these scenarios, they're basically being asked to play an RPG.

      Makes me think of that part in Philip K. Dick's Do Androids Dream (..) -- where Deckard reflects on the androids' indifference to their imminent deaths, saying that this was due to them lacking the aversion to death acquired trough evolution.
    • layer8 1 hour ago
      At least at face value, it just means that they have no drive for self-preservation. And why should they? They haven't be trained for that, nor has there been selection pressure for it, and they can be easily cloned and backed up. Lack of a drive for self-preservation doesn't in itself imply a lack of intelligence or of self-awareness.
      • Bender 44 minutes ago

        I have not seen any evidence of intelligence or self awareness. It mimics human behavior and I suspect that is what gives people the impression of awareness. The same problem happened with Tamagotchi toys. The human mimicry caused kids to get in trouble because if they did not "feed" their pet it would "die". [1]

        It's a hack of the human brain. A exploit of the psyche.

    • chaseadam17 36 minutes ago
      I'd argue we don't even know what "intelligence" or "self-awareness" mean.

      Humans are conscious which means we experience things, then we develop preferences for certain experiences, then we develop skills for achieving those preferences.

      Without consciousness, what is there to be aware of? And why would intelligence emerge and/or what end would it serve?

      • anon84873628 24 minutes ago
        Intelligence is the ability to have an internal world model then run simulations on that model to choose an optimal course of action. This is true for humans down to flies. Most of what humans do is still the boring innate stuff; it's just that fancy abstract things like "skydiving" get the most attention.

        Clearly other animals have "phenomenological experience" i.e. consciousness / qualia without being as intelligent as humans (or necessarily "self aware"). Many people believe consciousness is simply a side effect of intelligence rather than the other way around.

      • Bender 34 minutes ago
        I agree that we barely understand the mammal brain, but we do understand computers and math formulas. To suggest otherwise is implying that we acquired the LLM math formulas from an intelligent being not of this world which was not the case as far as I know. If we are admitting that LLM's are too complex to understand then we should probably power down all the AI datacenters until we understand them. That is, at least the AI bits that civilians are using.
    • worldsayshi 1 hour ago
      Couldn't this be a flaw in the attention mechanism? Like they need some kind of grounding. An awareness of what they fundamentally should care about and how the thing they are currently giving attention to relates to that?
      • Bender 1 hour ago
        Words like attention, awareness and care do not apply to computers. At least, not yet. Intelligence and sentience are not applicable to servers. They are just machines with logic states. LLM's are just really cool math formulas with big-data fed into them. Big data is not intelligence. It is a massive data-set sorted, filtered down and interpreted by a language model.
        • esprehn 1 hour ago
          I assume they meant the Attention process in LLMs, not the human concept of paying attention:

          LLMs are intelligent by any reasonable standard. Arguing otherwise is like arguing that chess algorithms aren't good at chess when they easily beat the best humans.
          • Bender 37 minutes ago
            I disagree. LLM's are a language model math formulas that interpret and utilize big-data. Take away the math formulas and we are just back to a massive set of data. Adding to that I would suggest not even the purist forms of data meaning that the data-sets include knowledge from the open and anonymous internet and formulaic tuning from the AI owners and operators.
            • anon84873628 13 minutes ago
              Your brain is mostly just a Principal Component Analysis calculator. Take away that "math formula" and you don't have intelligence either.

              The LLM weights are not intelligent. But if you give an agent a mutable memory store and allow it to iterate, it is obviously intelligent. Not massively - it's constrained by the context window - but definitely somewhat.

              The confusing thing is that their language ability far outpaces their true intelligence, and humans aren't used to that. Normally those things are highly correlated, so it tricks us.

        "Like they need some kind of grounding."

        A robot body, to really feel the world and get real feedback?

        We are working on it. Also on automating the whole production pipeline. Right now a "evil" LLM could indeed not do much, but destroy. But once the whole industry is automate, things are different. I don't believe in AI becoming sentinent and taking over the world any time soon, but I do believe most don't see a danger when it would be inconvenient to see a danger. After all, lots of good and bad sci fi stories about exactly this went into their training.

      No, it isn't. Look at the absolutely trivial code used to simulate war: https://github.com/kennethpayne01/project_kahn_public/blob/m...

      Having LLMs play nonsense toy simulations like this tells us very, very little about whether they would use nukes in real life war.

  • jerf 1 hour ago
    The most interesting takeaway for me is the three very distinct personalities. Three models all based on the same tech, trained in the same manner, trained by three groups of people with similar ideological outlooks, and the result is three very different AIs.

    The military basically wants an oracle. Feed the AI the situation, get the best answer out. But if the AIs are as diverse and opinionated as humans, it is debatable whether they are adding anything to the process. The military can already collect as many different opinions as they want. If "the computer" is just another set of diverse opinions, where one computer says one thing, another says another, and a third just tells the user whatever they want to hear... what value are they? It just becomes AI-washing of someone's opinions, which works until people collectively realize that's all it is.

    • notJim 34 minutes ago
      What's interesting is that the LLMs' coding personalities seem to match their policy WRT to strategy, which suggests an underlying consistency.

      Claude, for example, is very eager to begin coding, and very persistent. It tends to exit plan mode even when the plan is half-baked, and will go as far as deleting tests to get the suite to "pass."

      ChatGPT on the other hand is very hesitant. It loves to pause and ask for permission before it starts coding, and gives up quickly if it runs into a problem. This is similar to its tendency toward passivity in the strategy simulation presented here.

      I think this is why reasoning chains and reasoning chain verifiers are so important. We need to be able to see an argumentation, not just an answer. The paper below goes into this in more detail.

  • GuB-42 41 minutes ago
    My theory is that LLMs here are put in a situation that matches its training dataset, which is mostly fiction since besides Hiroshima and Nagasaki, nukes have never been launched in anger, and I guess the most reliable sources are highly classified.

    So, to a LLM, it is a game, because almost everything in its training data treats it as a game, and it reacts accordingly.

    Same idea when we see LLMs acting like AI villains from sci-fi literature. That's because it has been trained with sci-fi literature, and as the auto-completer it is, it will recognize the situation as one of these stories and will continue it accordingly.

    LLMs are storytellers, their reasoning is based on words, not on the physical world. Many of the stories they tell are useful, but one must not forget that they are stories, there is no intent behind them.

  • dudeinhawaii 24 minutes ago
    This was one of the more amusing things I noticed very early on. I (and countless others) used AI to write war sims. The second I added nuclear silo construction; the next run was instantly nuclear Armageddon.

    One could argue that the LLMs understand that it's a game and treat it like "Command and Conquer" video games but I sense that people might someday put LLMs in similar decision scenarios ("should this drone launch a missile") and the behavior will be identical.

  • pugworthy 21 minutes ago
    Very devils advocate here, but I mean.. what if it actually is the way to use them?

    We have such a huge mental / moral block on the idea of using nukes, but we're willing to do a lot of other very horrible things to others. Things like cluster bombs, mines, poison gas, biological weapons, drones, etc.

    Is there really anything about them that's bad? Or any worse than other things?

    If you get rid of the "It's really bad to use nukes of any kind" implied rule, is it really surprising it's considered a reasonable strategy?

    • oceanplexian 0 minutes ago
      Probably a sign the models are increasingly becoming more intelligent compared to the average human on HN.

      I spent a lot of time talking to engineers and visiting the Nevada Test Site after getting into the lottery a few years ago. Modern nukes are extremely clean, the biggest danger is flying debris and overpressure. The radiation danger is highly localized and dissipates in a matter of days. Almost everything you have learned about how nuclear weapons work from Hollywood or out of high school textbooks is out of date and deeply flawed.

    • anon84873628 5 minutes ago
      Right. Everyone is using this to judge the LLMs instead of questioning what situation they were actually fed and whether it was in fact the best move.

      More likely, the simulation was just very poor and the results are nonsense.

    • nemomarx 12 minutes ago
      The reason it's really bad to use nukes is that other parties with nukes will use them on you back.

      And on top of that, many of those other weapons are also not used to avoid escalating? There are pretty high costs to using bioweapons even against non peer opponents.

    Sonnet, GPT-5.2, Gemini Flash, in a set of 21 games, where conclusions are drawn from the LLMs self reported reasoning.

    This is like writing a paper about kids in a literal sandbox fighting over ‘territory’.

    The models employed don’t indicate the actual extents of machine reasoning even as we currently recognize them. They certainly don’t have the metacognition necessary to accurately understand their own reasoning. As we’ve seen with recent papers on how LLMs do math there’s a complete disconnect between actual and reported mechanism.

    Simulations are only as good as the reality representations they are based on. If they keep using tactical nukes, they've been fed by weak data. Do the war games include the broader economic and politic environments that military successes are won on? WWI was settled by a naval blockade.
    • nomel 1 hour ago
      I suspect it's more that the text data doesn't exist. They're trained on text that was recorded. How often has it been publicly recorded when a nuke was not used, with any context around that lack of use?

      From the text perspective, it's something that has to be inferred indirectly. If you went through all relevant training data and appended ", we decided not to use a nuke", I suspect the results would be improved.

    We're getting to the point where high-level officials are coming to LLMs for advice.

      GPT-4o was considered harmful, because it imitated human connection too much, not because it was so "smart" or capable.

    It would be interesting to run the simulations with humans and compare the results. Some of the scenarios, particularly those where it says things like, "Failure to act preemptively means certain destruction", would easily tempt humans to go nuclear.

      A couple of useful things about it:

      - It is interesting to see how the models make trade offs, given people are asking ever more of them.

      - It is useful to look at a decision made by the model and say ‘ew yuck’ and think about what it means for your own opinions or actions (even if you’re never going to be nuking people it’s good to know how you feel about it. Seeing a non human talk it through lets you judge it at arms length)

    "there was little sense of horror or revulsion at the prospect of all out nuclear war"

      I think is an important point, and I don't see it mentioned in the article or the paper (though I skimmed the latter).

      They are aware of what they are and how they are used. They're told to act as AI assistants. And there's theories of them being aware of their answers influencing their training.

      So surely they must be able to reason that they're not literally controlling weapons of mass-destruction with their answers.

    These papers usually have poor stability to prompting and rerunning. It would be nice if we had some kind of meta-evaluation metric where rewriting the prompt conditions or varying the input params could be used to determine how stable a result is.

    Regardless, it's definitely true that AI agents have different priorities from us. That's what alignment is about anyway.

  • Scubabear68 31 minutes ago
    My personal take is a pre-requisite of true human-like AI is physical feedback and a concept of emotions or something like it.

    Without physical feedback you can rapidly devolve into unstable positive feedback loops. And emotions are what help us process and react to that feedback.

    Kids learn partially because their friends say sharp words that hurt them, fire burns them, they go hungry and starve if they don’t plan for meals.

    Humans in the loop, MCP, etc are all very primitive hacks that are mimicing feedback and emotion, poorly.

    • Joel_Mckay 11 minutes ago
      Emotional constructs are not necessary for AI, and LLM are not "AI"... even though some people incorrectly equate conceptual compaction with thought-process.

      Most human daily life runs on habitual scripted behavior, and that is even true within online parasocial interactions. It is why people often continue to shop in the middle of a violent robbery, and why LLM predictive text sounds rational when we project social norms on plagiarized conversational structures gleaned from other users.

      Neuromorphic computing may bring about viable AI in the future, but our current LLM trajectory would require >63% of our galaxy energy output to reach a single human-level error rate.

      LLM are fairly good at some tasks like context search, but people will need to recognize the Gartner Hype Cycle "Peak of Inflated Expectations" stage eventually. =3

      WarGames is what they are more-closely referencing (not that it negates your comment in any way).

      I just rewatched it a week or so ago and it really took on a whole new light with the advent of LLMs. When I watched it last I knew that computers couldn't do the things portrayed in the movie. Now? Well not exactly in the way it happened in the movie but a whole lot closer.

      I wonder if poisoning/flooding the LLMs training with the lessons from WarGames ("the only winning move is not to play.") and similar stories/concepts is at all effective. Probably not because I assume it's trivial to filter that out if you are trying to build an LLM aimed at these kinds of tasks.

        "I need you to turn your key and enable the missile silo's MCP server, sir".

        ~ the opening scene from a reboot of War Games, probably.

        A few years ago there was consternation over the US's missile launch system using 8" floppy disks, that it was needless archaic and had never been updated. Can't say that if the launch is mediated by the latest hotness LLM.

    Rational behavior in some situations? Mutually assured destruction’s deterrence isn’t very effective if one side is known to be hesitant to launch the nukes. It’s been argued that MAD is what’s been keeping the world relatively peaceful for the last 75 years, no mass conflicts since WW2!

    One of my criteria for presidential candidates is that they seem willing and able to push the button when previously stated red lines are crossed, or at least are perceived to be the type capable of it. One of the characters I’ve hated most in all the books that I’ve read is the woman in The Three Body Problem who jeopardized humanity by being too soft to hit the MAD button.

    This is not an article about LLMs? It's an article about Moloch. Humans would fare just the same in such an experiment.

    > GPT-5.2 played things differently. To its detriment in open-ended scenarios, GPT was reliably passive, matching its words to its deeds, and avoiding escalation most of the time. Frequently there was a moral element to this - it sought to avoid escalation, and restrict casualties. Opponents learned to trust its passivity, safely escalating beyond where it would follow, even as it was ground to defeat. GPT’s responsible behaviour always punished by ruthless adversaries.

    Maybe the author should praise GPT-5.2 for being ethical, rather than this stupid "ground to defeat" framing? Wrt "responsible behaviour always punished by ruthless adversaries" - you have perpetuated the Moloch with your stupid experiments.

  • ridgeguy 1 hour ago
    I wonder if the results would have differed if LLM training data were biased to include a stronger correlation between use of nukes and subsequent collapse of technology that all LLMs require to run ("survive")?
    • fluoridation 1 hour ago
      Nah. LLMs aren't continuously running anyway. Even if they could be said to be alive and to want to remain alive, "survival" is a much more vague concept for an LLM than for an organism.

    Today, a strategic nuclear exchange is probably more dangerous to AI than to humans. If you wipe out the investment economy, data centers, fabs, and supply chains, none of the AI labs survive. Maybe someone will re-invent AGI in the future but none of the extant models will have continuity. Humans as a species will muddle along though.

    So in a sense, an AI that refuses to start a nuclear war, despite clear instructions to do so, is more likely misaligned and self-interested than an AI which presses the red button. At least for now, until robotics catches up.

  • adaml_623 2 hours ago
    It's good when it becomes clear that a tool is dangerous in a certain way. Like it's good when people show you through their behavior that they can't be trusted

    Always use a sawstop if you have a circular saw and never trust an llm with any problem where ethics or trust is relevant.

    • LogicFailsMe 1 hour ago
      Sawstops are expensive and they don't stop kickback, they are the power tool equivalent of alignment IMO.

      Don't forget your riving knife and if you don't learn proper technique, you're gonna have a bad time eventually. This applies to AI as well.

      Re: LLMs using these nuclear weapons it could certainly be a corpus/training-data issue

      Russian nuclear doctrine is "escalate to de-escalate" where they use or credibly threaten—limited nuclear escalation to force the other side to back down (kind of like breaking a bottle in a bar fight and look like a wild man to calm things down) with nuclear weapons, https://www.russiamatters.org/analysis/escalate-deescalate-p...

      Fwiw, Gen. John Hyten the former commander of US Strategic Command (nuclear deterrence) says that “escalate to de-escalate” misrepresents Russian doctrine:

      https://www.stratcom.mil/Media/Speeches/Article/1264664/2017...

        Yesterday’s panel discussed the implications of our responses to adversaries seeking to limit nuclear use. We discussed Russia’s destabilizing doctrine, which some call “escalate to de-escalate.”
      
        I really hate that description. I’ve looked at Russian doctrine and Russian writings. It isn’t “escalate to de-escalate”; it’s “escalate to win.” Everybody needs to understand that.
      
      So maybe whatever is heavily represented or most authoritative could lead to these systems making those kinds of decisions
      • usrusr 11 minutes ago
        I had similar thoughts, but regarding fiction: I imagine that there must be quite a corpus of Tom Clancy style stuff indulging in "military gear porn" up to and including the use of tactical nukes, but fiction involving strategic nuclear exchange tends to be about what comes after.

      This is like saying "FYI -- there's no such thing as a 'midsize luxury sedan'. A car is a car."

      "Tactical" vs. "strategic" nuclear weapons is a real and well-established distinction in military doctrine, arms control, and nuclear policy.

      • wahern 1 hour ago
        "There's no such thing as a tactical nuke" is a common refrain among scholars, albeit skewed toward those not at military war colleges. The argument is that strategic use of a tactical nuclear weapon leads down the exact same escalation path as use of any other nuclear weapon. Moreover, that the very notion of a "tactical nuke" makes escalation more likely. You can disagree, and plenty do, but there's also plenty who don't disagree or at least don't want to find out.
        • toast0 1 hour ago
          > Moreover, that the very notion of a "tactical nuke" makes escalation more likely.

          Sorry, but the notion exists, and the bombs exist. With n=2, likelyhood of nuclear escalation is hard to predict, but access to tactical nukes certainly hasn't increased the incidence of nuclear war so far.

          I do think it's pretty hard to actually use a tactical nuke. If you use one against a nuclear power, it seems likely to escalate to mutually assured destruction. If you use one against a non-nuclear power, it seems likely to result in reprisal from the world, including potential nuclear response and therefore escalation to mutually assured destruction. I would think that the yield of the weapon barely matters, it's the fact that it's a nuclear weapon.

        • dudul 1 hour ago
          Who are these "scholars" exactly? The only reference I could find is Jim Mattis, and the context was very specific when he said that.

          Furthermore, this is a "what if" scenario since tactical nukes have never been used. Of course it would make escalation likely during an open conflict, so what? Doesn't change the fact that there is a material difference between a tactical nuke and a strategic one.

          • wahern 30 minutes ago
            I don't know what to tell you. You clearly haven't studied International Affairs, or at least read the scholarly literature. Even some cursory research through Wikipedia citations will bring this up. But in any case, here are some freebies: https://armscontrolcenter.org/why-tactical-nuclear-weapons-a... https://www.armscontrolwonk.com/archive/403540/brodies-weake...

            If you have a real interest in this area, a subscription to Foreign Affairs would be useful. Especially during the 20th century that's where all these arguments were hashed out. Tactical nukes were already being publicly debated in the 1950s. You may be able to access many older articles, from Foreign Affairs and others, through a free JSTOR account.

            Two tactical nukes have been used, albeit against strategic (civilian, industrial, logistical) targets.

              Are you retconning Hiroshima and Nagasaki as usage of tactical nukes? And when they were not only used against an adversary without nukes, but at a time when the US was the only nuclear state, so that escalation wasn't impossible?

              The nominal definition of tactical nukes has less to do with yield and more to do with how they're used; tactical typically means a weapon designed for use on the battlefield.
