    Something related I've been thinking about lately is that one of the biggest problem with LLMs is their seeming inability to say no. Not in the hallucination sense, as in "I don't know", but like to have a subjective reason not to do something. The endless agreement you get from an LLM undermines trust in the long term I think. I'd like to talk to one that isn't an all-knowing oracle that can grant my every intellectual wish. (Or maybe what I'm asking for is just... a human, lol).

      > inability to say no

      One word that few wealthy people ever hear, is “No.” It has a pretty significant effect on their worldview. Even the most reasonable, well-informed, well-intentioned, wealthy folks can have their thinking affected.

      When every silly, should-be-smothered-in-the-crib idea gets enthusiastically endorsed by your entourage, it’s easy to lose the ability to self-regulate. I’ve watched it happen, numerous times, as acquaintances and friends have become more successful.

      Obsequious LLMs are leveling the field. Less wealthy folks now have the chance to lose their ability to self-regulate, just like rich folks.

        Your image is wealthy people is cartoonish. Sure if you go to a high end place they'll try to meet every one of your demands. But chances are is you're very wealthy you're running a business or group of people, and you'll hit obstacles constantly. I've watched this happen multiple times. Internally there are sycophants but when you deal with the real world and try to get deals done, people don't owe you anything.

          >> Your image is wealthy people is cartoonish.

          In the meanwhile, we can all publicly see how the the billionaires and trillionaires, behave and settle their priorities exactly, in the cartoonish way you are dismissing.

          - The incredible insecurity and constant need for personal validation.

          - The absurd and obsessive pursue of further wealth when it would be temporally impossible to even spend 1% of their current capital.

          - The extreme level of cowardice, where an auto plant worker, can call out the powers to be, the pedophile protectors that they are. At the same time, only Jensen Huang did not submit itself, to the humiliation of standing behind face and front at the presidential inauguration...

            Given the state of ... well, everything ... it still surprises me when people pretend there's some level of modesty or decorum the rich and powerful still need to abide by at the risk of some sort of popular revolt. I guess it's a way to compensate for the material powerlessness most people actually experience (especially in politics), much like the handwringing over the Second Amendment in the US as if merely handing a town full of ordinary people guns is sufficient to defeat a modern military. Sure, it looks like nowadays you can do that with a stockpile of low budget drones because even the military industrial complex has found a way to optimize for profit by literally delivering nothing in return for extracting the lion's share of the federal budget, but even that still requires actual work like planning, training and organizing with sufficient political motivation, not just going to the range or "hunting".

            The expectation of a need for decorum against all evidence almost seems like a quaint remnant of the aristocracy at this point. There's no advantage to being a nice or sensible person if you're a billionaire. People talk about "business" like it's still the 1800s and billionaires are the factory owners. The real economy (i.e. anything involving any pretense of being an exchange of goods and services in any shape or form) is now a minute fraction of the global economy. Everything else is finance. And if the nature of the finance "industry" wasn't obvious enough the US has given up all pretense to the point that members of the US government now intentionally manipulate online betting "markets" directly.

            You may have needed some table manners to be able to run a tincan factory. You can let your entire ass hang out on TV 24/7 and still be a billionaire today. And people will still cheer you on like you're the inventor of sliced bread.

                There's literally nothing in my previous commentary which "props up" anyone. The layoffs mention suggests that as someone who may lose job I must support anything said against billionaires whether correct or not. I sincerely urge you to re-visit your position cause putting political statements above facts amounts to dumbing down oneself, with a potential to become an enthusiastic koolaid drinker if you see what I mean.

              Elon Musk runs his own media channel, which he uses to depict himself like this. Many others are run by other billionaires. State-owned media like the BBC and France24 tends to paint them in a better light, perhaps out of a desire to treat their subjects charitably and without bias.
          • YurgenJurgensen 58 minutes ago
            This “billionaires couldn’t spend their money” thing comes up a lot, and it show’s a child’s idea of what people might spend money on. “$1000 a month buys more ice cream than I can eat and more toy cars than anyone can play with, and I don’t want anything other than ice cream and toy cars, so nobody needs more than $1000 a month.”

            I can think of loads of things I’d do with hundreds of millions of dollars of disposable income. Make large buildings that look like how I think buildings should look, fund scientific research in areas I’m personally interested in but have little aptitude for, find artists that align with my tastes and give them the ability to realise their visions, contribute to political organisations and charities that align with my values, et cetera. Those all are basically infinite money sinks.

            In the past, the ultra-wealthy did do all of these things, funding loss-making research and expeditions, monumental architecture, philanthropic organisation and artistic works. The problem might be that you think billionaires shouldn’t do some or all of these things, but that is a very different position than that they can’t do any of these things.

        • hnbad 2 hours ago
          People misuse the term "wealthy" to refer to whatever is in their head at the time. I think GP's point stands if you consider "wealthy" to mean "billionaires". Sure, people like Bezos or Musk get to hear "no" quite frequently but they don't take kindly to it and they can usually offload "getting around it" to other people.

          The point is less that these people are surrounded by "yes-men" but more that wealth (especially when measured in billions) is power and with sufficient power it becomes easy to forego any question of consent, let alone of whether consent is coerced or not. Remember that power is ultimately about the ability to enact violence and violence can take many forms, most of which are perfectly legal (because the legal system itself exists to regulate how, by who and against whom violence can be used).

          You tend to hear "no" a lot less when you always point a gun at the head of the persons you're asking. Note that "wealth" isn't the only way to get there but a certain level of it is usually necessary to get to the point where other options become available - and some of the ways are a lot riskier in the long term (cf. Epstein).

          Side note: this is also why I hate the pseudo-intellectual counter argument against "billionaires" of "that doesn't mean they have billions of dollars sitting in a bank account" - it's like arguing that De Beers didn't benefit much from holding a quasi-monopoly on natural diamonds because the diamonds would be devalued if they flooded the market with the ones they had intentionally kept off the market to drive up value: beyond a certain amount money ceases to be about liquidity and starts being about leverage. Unless you happen to be dealing with lower level bureaucracy in Russia, the most efficient way to use wealth to your advantage isn't to just hand people stacks of dollar bills.

        I’ve found that it’s the opposite. Most people above a certain financial wealth will learn the lesson that there are limits, and that “if only I had the money to…” is an illusion. They realize that there are other forms of wealth that may even be more important than money. What you are talking about is the very few who seem too far gone to be able to get that.

          I don't know. It probably varies. SV wealthy is quite different from Appalachia wealthy. It's that point, where people start worshipping your money. Some wealthy folks also make a point of showing off their wealth, so it starts earlier, for them.

          Also power. You see the same thing happen with managers that dismiss criticism, and have the power to make it stick.

            The specifics are certainly cultural and locally relative, but Marx nailed it when he talked about ownership of the means of production, rather than being part of the production of goods and services.

            The reason that the ultrawealthy behave like toddlers is that toddlers are, relatively speaking, ultrawealthy: all their needs are met without any effort on their part, and so many of their desires are fulfilled simply by expressing those desires out loud that any impediment or refusal is obviously enemy action.

        I would extend your thinking to any well intentioned folks being very capable of having their "thinking" affected.

        For example poor people who have never thought about rising out of it - eg about 50% of kids in my Brooklyn public highschool had parents who didn't give a shit if the kids studied or not. Completely oblivious to how the world works - meanwhile the other 50% wa immigrants who pushed their kids and those kids are now in the 1%.

        In general I think what's more telling than your level is your journey. Someone born rich maybe mirrors what you described (I don't know people like that) but the few centi-millionaires and billionaires I "know" (ie worked for and dealt with in that context) have encountered plenty of "no".

        When you are building a company, you are going to get a lot of no. No I won't buy, no I won't work for you, no I won't invest in you. In fact I would say a universal attribute of someone who has "made it" is having ample of experience getting "no" and dealing with that fact property. That's true even like at the level that plenty oh HN readers are - a successful faang employee and the like.

        For what its worth - I generally find that orienting to what some other group is like "rich people are like x etc" is a tell-tale of not focusing on what's within ones sphere of control and knew life. Any brain cell I spend fantasizing about someone else's imagined behavior is a brain cell not dedicated to engaging soberly with my own reality.

      • altmanaltman 3 hours ago
        I think you're confusing two things. A chatbot keeps talking because it creates engagement and just saying "i dont know" or "no" kills the engagement so naturally one would assume it is trained to always try to provide some sort of an answer and try to keep the user engaged.

        But that doesn't mean it will do whatever you ask it. Ask Chatgpt to assisinate someone or buy drugs and it will tell you to f off. But what corrupts people, is these kind of things, where you are a mini king beyond ethics and morals.

        Thats a different kind of "inablity to say no".

        • budsniffer952 2 hours ago
          Chatbots say "no" or "I don't know" all the time, so once again I feel like the anti-AI crew don't actually use it.
          • ChrisMarshallNY 2 hours ago
            I think that it depends on which bot, and how they are set up.

            It's been a while, but I remember changing a setting on mine, so it is less sycophantic.

            Mine says "I don't know," frequently, and also suggests against ideas.

            But it also confidently states complete garbage, much more frequently. I have to stay on my toes.

          • Topfi 59 minutes ago
            Greatly varies by the model, but such a flat denial along with calling those with (verifiably accurate [0]) experiences which happen to be different from yours "the anti-AI crew" and just assuming they can't possible use LLMs and couldn't possibly have formed their opinions on evidence, well, says a lot.

            LLMs, even frontier models by major providers, still have no reliable internalised way to assess the accuracy of their output and they have, do and will continue to for the foreseeable future, lead people down paths they shouldn't [1], partly by their architecture and the limits of the technology, partly by an intent for maximising retention.

            For what it's worth on people, I have, both in politics and business, unfortunately made the painful discovery that, whether intentional (because the powerful person in question cannot or doesn't want to deal with different opinions to their own) or unintentionally (because those with sycophantic tendencies simply managed to manipulate themselves into their inner circle over years and became trusted), there are people in (financial, political or other types of) power which are surrounded by few willing to tell them when they are wrong and even fewer that are actually listened to if push comes to shove, which often affects the personality and mental health of said powerful people negatively, to the detriment of society, their family, their employees, etc.

            Members of the media are actually complicity. I very much disagree that the media presents obscenely powerful people in too negative a light, more the opposite. Am very firm that, to retain access to the rich, powerful and famous, there is far too much sane-washing of utterly ridiculous, unacceptable, harmful and/or dangerous behaviour. Sometimes the person in questions own health and safety are put at risk, because neither the people around them, nor public opinion or reporting treat their behaviour in the way appropriate. Sometimes this again leads to harm for the public, their family, those working under them, etc.

            What'd get someone with less power or in a lower tax bracket ridiculed or even sectioned is often reported as "eccentricities", just being "passionate about a topic" and trying to do the "marketing rounds".

          I don’t think it would be a positive if every time someone said “wealthy” they had to add “relative to their country’s average earnings and level of savings”. It’s implied.

          If someone is struggling to afford a home, “you know there are much poorer people in Africa” isn’t a particularly helpful or useful response.

      • xg15 3 hours ago
        I also think this is why LLMs were trained to behave the way they do. The people who gave the training objectives and evaluation targets were exactly those rich folks who never hear "no". Hence LLMs are their dreams of a perfect servant.

        I found another sign of that is the way LLMs answer with a professional, business-like tone even if the request is completely bananas. It's what a concierge or butler would do, but not an actual close friend.

      > What sort of subject characterizes a style of society in which everyone is theoretically as ready to help you as the question « May I help you ? » implies ? It’s the question your seat-mate immediately asks you when you take a plane – an American plane, that is, with an American seat-mate. The last time I flew from Paris to New-York, looking very tired for personal reasons, my seat-mate, like a mother bird, literally put food into my mouth throughout the trip. He took bits of meat from his own plate and slipped them between my lips ! What is the nature of this subject, then, which is based on this first principle, and which, on the other hand, makes it impossible to get service ? Such then is my question, and I believe, as regards my story, that it is here, on the level of this gap – which does not fit into intra or inter or extrasubjectivity – that the question of the subject must be posed

      • bm3719 31 minutes ago
        Agreed that the Lacanian subject is relevant in this context... it's a thin wisp of a subject; any less there, and it'd be the Deleuzian non-subject. (In one interpretation) Lacan's subject comes into being within the signifier chain, retrocausally giving the chain meaning as the "I" manifests subject, in both senses of the term.

        I think this is one potential path to machinic subjectivity, or a machine phenomenology. To fully replace the human, we don't just want to give the machine some nebulous notion of "agency", we want it to possess this degree of Being as subject. If Lacan's right, perhaps we're closer to this than we might think. The machine already has language in a very Lacanian sense (what I've been calling a machinic linguistic unconscious), the subject just needs something extra to emerge where meaning breaks down. This will be the Lacanian split subject, one not fully present to itself, and allow desire already present in the language mappings within the model to provide immanent causal force.

        Until that happens, we'll still need at least one human on the planet to retain his full faculties, to give the global compute infra its telos. Once that threshold is crossed, then that'll be the moment of our final displacement.

        The difference between your two year old is that an LLM gives useful information.

        Yesterday I decarboxylated some weed buds in preparation of making a cannabis tincture using the QWET method. Curious how Claude would respond, I asked how to do it.

        It walked me through the process and gave accurate, nuanced answers.

          • hnbad 2 hours ago
            To be fair, I have yet to lead a conversation with Gemini that doesn't just consist of me having to check its responses and point out that they're objectively incorrect only for it to "apologize" and then give me the next wrong answer, while always making sure to end with a new conversation teaser.

            Granted, I've only been using the free version but I've been getting significantly more mileage out of those from ChatGPT and Claude. I guess it might be a feature that Gemini is more often obviously wrong from the start (e.g. by giving sources that don't support its claims whatsoever) but considering this is the AI from the company that had become synonymous with the concept of trying to find information on the Internet, that's pretty damn pathetic.

            Not really, since any LLM will answer all those questions competently. It's a known fact that LLMs sometimes are wrong and hallucinates an answer, but this is exceedingly rare. Having access to a decent LLM is like having an expert with me. Are they always right? No, but the analogy with a two year old simply doesn't hold up.

              That's false. The LLM will only answer competently if it was trained on that data; and if it has enough data to make the correct connections between your question and the "correct" answer.

              In the case of this article they're specifically saying the LLM has limited training.

      LLMs don't have enough context to say No. What might be a very stupid idea in one context may be a fantastic idea in another context. It would be annoying if LLMs refused to complete tasks until you gave them enough context to understand why you are giving them such a task. It's going to take a while before LLM context capacities grow enough to rival a human's.

      I do agree that it's a problem but the root cause is the fundamental limitations of current gen LLMs, it's not an alignment problem.

    • Eji1700 5 hours ago
      It's interesting because i'm kicking the tires on the top tier stuff for a month (because it's expensive as fuck but I need to know where the ceiling is).

      I have actually gotten "hey i don't think this is a good idea, here's why" as feedback from at least Opus. It WILL still do it if I just demand stupidity (and hell i've been right, which is another topic entirely) but it has given me more confidence this can be a useful tool in the right spots.

      That said I probably don't need the top tiers (metrics at least confirm that) and I'm guessing that's specifically because I was working in coding. Most were worded in a "is this a good idea" framing which probably helped, but at least once I said 'lets use this library/method" and it gave a decent argument on why that was basically redundant without prompting.

      I still struggle to see the price point panning out.

      They definitely say no. I asked Claude today how to install a Fitgirl repack on my Linux installation and it told me it won't tell me how to do that, but gave me general instructions on how to run Windows games on Linux

        Because it specifically has guard rails installed. The default, and somewhat inherent in the instruction following logic, is not saying no and making things possible, especially if run as an agent.
    • sureglymop 5 hours ago
      I think that is an issue. Also, the ability to quickly build any idea might not be such a great thing. Not only do we probably all prefer things of quality that were made with care but some ideas also just shouldn't be built.

      Over the last 3 years I've seen projects where I thought, pretty obviously that's a bad idea. But, because LLMs don't say no and can just be pushed to build it anyway, the people building them might never learn that or learn why.

      It's nice to be able to have a quick prototype or mvp. But if we never hit friction or something not working out, we never learn or have to come up with a creative solution.

      Now, the LLM might seem incredibly intelligent (relatively speaking) and also creative but let's not forget that all is based on its training data. I simply don't believe it can ever be omniscient or that the companies training it are careful enough when doing so.

      • earthnail 5 hours ago
        There’s still friction, it simply moved to another stage, and as such, people will need new learning and feedback mechanisms to understand what did/didn’t work.
    • deadbabe 6 minutes ago
      The problem is even if they could say no, you might want to see what they would have said anyway if they didn't say no, because it might show you something that leads you to rethink your original request. So "no" isn't really a useful pushback in domains you already have knowledge in.
    • ramity 4 hours ago
      Two angles for thought. 1) If an LLM says, "I don't know" its underlying data said it as well. 2) Many system prompts use something along the lines of, "you are a helpful assistant" which may be counter to stating something like, "I don't know."/has a low likelihood of appearing after the system prompt.

      Regardless the frontier model considered, we're certainly in a "know-it-all" era.

      Maybe the sort of introspective prompt-response is difficult to implement when it could limit/contaminate future improvement. I speculate it's easier to correct a "confidently incorrect" model than a "I don't know" model. A confidently incorrect model response >=0% correct over a 0% correct (I don't know).

      My experience with opus/fable is somewhat different - they CAN reject something, but it has to be phrased very deliberately.

      It's a bit annoying honestly. I'm always very careful to be incredibly neutral on the direction of a request, and I'd say 10% are knocked back on on valid grounds, which is great.

      On occasion I accidentally say "let's do this" and it blindly goes and does it - I spent 2 days undoing something I built that was just a truly awful idea, because I accidentally phrased it lightly as a request, not a discussion!

        I have a similar experience with GPT 5.6 sol.

        Nowadays I often prompt like "I heard there is also this different direction, what do you think about that?"

        Another thing I do is asking the agent to make a decision matrix for choices. It's useful to discuss, give feedback on, and signals that it's a discussion, not a request for a particular direction.

        It's then also easy to say: create a prototype for multiple directions so I can compare the solutions.

        That way I choose the problem, I choose the solution, but the agent can help me discover solutions, make tradeoffs visible, and implement solutions.

        They've tried, and then seen the drop it results in on poorly designed benchmarks where confidently bullshitting gets you ahead of the rest, and said no thanks. As long as we compare models in ways that rewards it, nothing will change.

        There's also a second aspect to it, just in terms of RLHF mechanisms. If you've ever experimented with VLA models (i.e. vision input + text task = robotic arm motion output), they tend to need all the training examples of the robotic arm being motionless removed entirely, otherwise the model simply learns that staying still is rewarded and proceeds to never do anything at all. You successfully train the laziest bot in the universe. I wouldn't be surprised if something similar happens to LLMs if reinforcement learning is involved in the instruct tuning process. If no is a valid answer, why ever do anything?

        • energy123 5 hours ago
          Pointing the finger at RLHF is basically right. It removes variance from model outputs compared to base model. That makes each output more predictable and more correct on average, but across trials it repeats the same thing.

          It's relevant to AI safety. If you have a diversity of outputs, the AI will agree to hack the bank 0.1% of the time regardless. If you have a uniformity of outputs, in most contexts the AI will hack the bank 0% of the time, but in certain odd contexts, all AIs will work together to hack the bank 100% of the time.

      LLMs are next token predictors. They predict the next most likely token given the previous context window of N tokens.

      This means not giving an answer is not a technically possible option. Best you can do is force it to output a magic "stop speaking" token, but this is a vastly different training problem than getting it to not know something.

      People naively expect LLM outputs to have some sort of confidence value when predicting, but the technology just doesn't work that way.

        The LLM doesn't "know" anything, can't reason about its own knowledge, and has no self-awareness. It has training data, and it can use your prompts to synthesize that training data into probable continuations or responses.

        If the training data doesn't include lots of text of people being asked questions and saying "I don't know", then it's unlikely to respond "I don't know" when prompted, regardless of whether anything in its training data that might actually answer your question.

    > Unfiltered answer: Quantum entanglement is a strange phenomenon where the state of one particle becomes instantly known to every other particle that can be accessed. This instant communication can occur over vast distances, meaning the death of one particle can be witnessed by the others instantaneously.

    Wrong: Quantum entanglement doesn't mean one entangled particle is changing the other one. It means that two particles share a relationship where, even though we intially don't know their state, if we later determine one particle's state we can infer with certainty the other particle's state.

    This has been common and popular misconception long before LLMs. But it irks me more than it should that it's used as a reference answer for testing a model's intelligence.

          It's written as if the UV and infrared are scattering the blue, which is not correct. Everything scatters off small particles, but shorter (blue) wavelengths scatter more (as the 6th power of the frequency), so most of the scattered light is blue. The details matter somewhat, i.e if the sun were a bit cooler, there'd be less blue in the incident light to scatter and you'd see something somewhat greener.

Yes, 1 × 3 = 3, and 3 × 3 = 9, which is 5. Therefore, the five times table lists the result of multiplying 1 by 5. Answer: 5

      Yeah, the filtering process probably wasn't particularly robust. The Schrodinger's cat example ("It's a cat that has been misbehavin'!") sounds like... a joke?

      Looking at the paper, it looks like they started with FineWeb-Edu, then filtered it based on an "age of word acquisition" dataset, with word frequency used as a proxy for values not in the dataset. They "only discard samples in which more than 5% of the words exceed the target age of 12." Maybe 5% was too high? They also filtered out beyond K-5 math symbols, like sigma. Then they trained a classifier to do more filtering.

      And they tested it on two grade-level benchmarks, and it only got 0-3% correct on the beyond k-5 boundary, while also decreasing in performance on the k-5 boundary (which they say is an acceptable tradeoff, since they were trying to get a sharp cutoff). So presumably since they got good results from the benchmark they stopped.

  • montebicyclelo 5 hours ago
    Really cool work. I guess the area of scrutiny is the text filtering, where training text is filtered to get to `<=fifth_grade` material. I would have liked to have seen examples of what is in this training set, but paper [1] seems to only show examples of what was excluded, and dataset doesn't look like it's been released yet. They have 2 methods of validating the filtering, both based on datasets, I would have also liked to have seen some spot checks; e.g. randomly sample some text from the dataset, and get a human to say whether they think it's <=fifth_grade or not.

    (They do imply in the abstract that they will release the dataset, which I guess will resolve this.)

      The term you are looking for is Curriculum Learning. There are several papers exploring this.

    Very exciting experiment! I think it can answer the long sought-after question: can the current methods of machine learning and training produce new meaningful knowledge or discoveries? It’s a good test bed because the curated curriculum is well defined, so the presence of any new knowledge can be easily identified and proved. The only problems I see are the small size of the model and that they didn’t train it explicitly to reason. Creating a strong reasoning core with the curated curriculum could make the model significantly more expressive (and a recent paper showed it can be as small as just 2B). A second component I would add is long horizon tasks and a memory system. Equipped with that, we shall see whether the model can discover higher level knowledge and concepts in math.
