I don't think the next-token-predictor thing should increase anyone's confidence that LLMs aren't conscious or can't escape the control of their operators. A very closely analogous argument would "prove" that humans aren't conscious or can't do [insert task here] either. (No, I'm not saying that any of this is true of today's LLMs, I'm saying this particular argument doesn't work.)
You can say that for any argument regarding consciousness, because we don’t have an actual, all encompassing definition of what consciousness is. In general I don’t think comparison with humans makes much sense, we should be able to discuss LLMs without always falling back to “but what about humans” (sorry for the caricature)
Shouldn't that imply that agnosticism is the proper view, rather than asserting that something is impossible on a next-token-predictor architecture?
(Note: I don't actually think the consciousness question is the most important one in the near term. Where I think this line of reasoning gets really dangerous is when people use it to assert that LLMs can't or won't engage in certain behaviors no matter much they advance; this doesn't have anything to do with consciousness.)
I think you can reliably assert that X != Y without having a complete definition of Y, as long as you can identify at least one property or condition that Y possesses which X violates.
So for consciousness and LLMs it could be Qualia, lack of semantic understanding, lack of continuity in time, lack of a high degree of integrated causal feedback, etc.
Or perhaps those are just features of human consciousness but not integral to consciousness as a whole. To me this then implies panpsychism to some degree, which I'm alright with too.
I would think that qualia is the element of that list that actually matters here- "Is there a way that it feels to be an LLM?" is, I expect, the underlying question being asked within "Is an LLM conscious?". If LLMs could only experience the timeless, nonlocalized color blue, they'd still be conscious. The presence of positive and negative valence qualia is additionally relevant if someone is getting at whether they have moral worth, but it's secondary.
But qualia are not directly measurable and the rest of the list only matters if those features are necessary for qualia, which we can't decide without such measurements or at least a strong theoretical model.
There are some vague notions about consciousness emerging from complexity that some people may advance as a nuance to your point, although that just makes rocks “minimally conscious”, not necessarily unconscious. If you take the view that the entirety of our consciousness’s comes from purely classical interactions (electrical and chemical), then thats not a difficult conclusion to arrive at, but the notion that consciousness can be derived from deterministic computation does not pass the sniff test imo.

The problem is, these models challenge our definition of "consciousness." Or at least they point out how hopelessly-inadequate our thinking on the subject is. Some people really, really don't like having their personal definition of consciousness challenged.
The correct response to "So what, it's just a next-token predictor" isn't a long dissertation on RLHF, training architectures, scaling laws and whatever, but rather to turn around and respond, "Sure, and how is that different from what we do?"
The "next-token predictor" framing is also a bit shaky. It's an accurate description of pre-training, where next-token prediction is a useful learning objective to force the model to learn higher-level representations. It's wildly misleading for a model put through an RL post-training campaign. The tokens it "predicts" aren't sampled from any naturally occurring distribution; the model's output is the result of an optimisation process that rewarded behaviour that was useful, and that's fundamentally different.
Right, but it's still useful to think of these models in terms of next-tokens because it helps explain that they look at every token that came before and use that to put out the next one.
You can get into RL as part of explaining why it's so unnervingly good at picking a next token.
That's true. The fact that an LLM is a pure function of (all previous tokens) -> (next token), with internal state like KV cache only existing for optimisation purposes, is pretty mind-blowing.
I guess it was more the "predictor" part I had issue with. There's a tendency to reach for statistical or probabilistic terminology to describe things that aren't usefully understood in those terms. For example in the "Speed Always Wins" LLM technical survey (https://arxiv.org/pdf/2508.09834):
> The gate is a crucial component to bring sparsity in MoE models. For a batch of input token representations X ∈ RT×D, the gate function G determines the probabilities of dispatching token xi to each expert e
...which is nonsense: the gate simply, directly, selects the experts. There's nothing probabilistic about it.
> The tokens it "predicts" aren't sampled from any naturally occurring distribution; the model's output is the result of an optimisation process that rewarded behaviour that was useful, and that's fundamentally different.
"Surprisingly, we find that the current training setup does not elicit fundamentally new reasoning patterns. While RLVR-trained models outperform their base models at small k (e.g., k = 1), the base models achieve a higher pass@k score when k is large. Coverage and perplexity analyses show that the observed reasoning abilities originate from and are bounded by the base model. "
This paper is less dramatic than you think it is and really just re-explains what RLVR does.
Let's stipulate that what pretraining does is train next token prediction over a gigantic corpus. You can then sample from this distribution repeatedly (cf the Large Language Monkeys paper) and count how often it passes some deterministic verifier.
What GRPO-style RLVR does is precisely this, but then reward the trajectories which passed the verifier. These distributions are _by construction_ within the accessible output space of the pretrained model; you're reweighting the distribution so that pass@k goes up, because that's (for applications like programming) very useful. RLVR is about making sampling more efficient; the only new information being added to the system is the presence of the verifier, and note that you only get a reward when the verifier passes, so there's essentially no mechanism for "teaching new facts" here.
Ooh. This looks like an interesting paper and there were a couple of things in the intro that I found counter-intuitive. It'll take me a while to digest the whole thing.
> Coverage and perplexity analyses show that the observed reasoning abilities originate from and are bounded by the base model
On the face of it this seems unsurprising given the policy gradient term directly minimises this difference.
I don't have a good feel for how the output of an RLVR-trained model concretely differs from the base model. My guess would be there are a fairly small number of "forks" where the training creates a token flip that sends the model down a more useful path.
The fact that the straight paths between the forks resemble the base model would again be unsurprising since (a) those are exactly the right context to continue to elicit more output that's relevant to solving the problem (so not penalised by RLVR), and (b) preservation drops naturally out of the policy gradient term you add to limit catastrophic forgetting in the base model.
Low perplexity could be explained by the relative sparsity of the forks in the output stream, and/or by forks already having high entropy in the base model. That also aligns with the pass-at-high-k: yes it's doing more exploration without training but it's a bit of a monkeys-on-typewriters situation.
Lack of novelty is readily explained by the fact that you need some nonzero pass rate in the base model to actually get some useful training signal from RLVR. That's a limitation of contemporary RLVR techniques, not a limitation on post-training in general.
I think there's room in that forks-and-straights characterisation for the RLVR'd model to be doing something that looks a lot like computation, while having low perplexity vs the base model. I don't see anything in my admittedly incredibly shallow skim of the paper that refutes that.
VibeThinker 3B is highly problematic for the thesis expressed in that paper. There is no possible way it could derive its reasoning capabilities from a bag of 3B parameters alone.
> the model's output is the result of an optimisation process that rewarded behaviour that was useful, and that's fundamentally different
I'm not understanding, can you explain this more? How does it become more than a next token predictor? Isn't the post-training simply altering the sampled distribution? And isn't that distribution naturally occurring? It's the distribution of "useful" next token?
I think this is smart, it seems to me that the best way to use these models its to approach them as a next-token predictor instead of an intelligent entity. That's how I've gotten the best results from them and allows me to avoid some of the pitfalls people fall into by anthropromising them.
Exactly. They ARE "glorified autocomplete" in an ontological sense. That says nothing about capability or outcome. The people who come out swinging against that characterization usually ignore the whole ontological argument (which is...the entire point) and go after an outcome-based strawman.
Depends. "Most" implies majority, and the majority of people are using these tools not for programming but in contexts where ontology is more relevant than capability (not that capability is irrelevant, but most people care, or are tricked into caring, far more about the former).
I don't know about "most", but there are a lot of people treating it as somewhere between "magic oracle" and "new friend"
Not to mention people more worried about whether the AI is motivated to hurt us than what human motivations can do with something that can autocomplete its way through every possible attack vector of cryptographic systems most of use would prefer remain secure.
(tbf I think the "glorified autocomplete" still works surprisingly well for programming outcomes too. Autocomplete [and fuzzy search of reference material] actually is useful and often right and certainly can save time even when it's only suggesting the rest of the variable name. But you might not want to commit everything it suggests...)
My favorite analogy for LLMs is "an intellectual chain saw". It does one thing, well, but that isn't "cut wood". It's "cut". What it cuts will happily include limbs.
But... These are also literally glorified autocomplete. Autoregressive language models are all autocomplete. It turns out that advanced enough autocomplete can do interesting stuff.
I generally like it still. It describes their failure modes pretty well, and in a way that most people already recognize. They're incomparably more complex, of course, but they are not intelligent and they are very much repeating what they've seen without any capability for factual accuracy.
Practically every other attempt at describing them leans too technical and unfamiliar (stochastic parrot) or too anthropomorphic (even describing them as "not like a human" gets people thinking in terms of humans, like how if I mention that your tongue is in your mouth all the time, using up almost all of the room, feeling your teeth and tasting itself, you're now uncomfortably aware of it and the numerous bumps on the surface).
You need to work from a reference that has both a shared understanding, and does not lead to problematic "if X has Y, and Z is like X, then Z has Y" seemingly-logical derived beliefs. "Spicy autocomplete" is a fairly safe starting point in both ways.
Which obviously raises the question of if we are just glorified autocomplete (or glorified pattern matching). After all, we evolved from things just trying to recognize the patterns for what will hurt us and what will cause pleasure.
The models themselves are indeed glorified autocomplete in terms of what they actually do (with things like agentic coding harnesses being required as a wrapper around them to make that internal autocomplete something more useful). Many people use this fact to critique LLMs, but many other common instances of people pointing out LLMs' apparent lack of intelligence actually come from people not understanding that the model is a glorified autocomplete underneath whatever interface people access them through, and the interface isn't providing the underlying model all the information they assume it would, making it seem less intelligent than it actually is.
There is a vast ocean of human knowledge, far beyond the capacity of any human brain, even within specialised fields.
Books helped "plug the gaps" in our knowledge, increasing the scope that a single human mind can encompass.
Web search engines did the same thing, but more and faster.
LLMs are like search engines on steroids, essentially a research librarian that operates at 1,000x human speed and can "in context" locate relevant information, adapting it to fit the hole it needs to go into as well.
It feels less like discovering new theorems, but instead having direct access to all theorems, which is hugely valuable in itself.
I.e.: the recent counterexamples to open conjectures has largely been about the AIs "trawling through all the things" and scraping together every bit of human-generated knowledge ever produced that is relevant to the conjecture.
Conversely, in the past, we had to "make do" with sub-standard solutions where the problem had been solved, but finding every relevant solution in the ocean of knowledge was prohibitively time consuming.
In some sense, LLMs will "raise the floor" in what is considered the minimum level of quality of a solution, where even throwaway / toy designs will now start applying every bit of accumulated wisdom instead of just some of it.
I feel like there has been a ton of noise about this, but frankly, no one has actually defined what AGI means. I feel like the goal post is constantly shifting.
Take for example Humanity's Last Exam. It is so broad and complex that while an individual in a specific field might be able to answer their specific area of questions, they certainly would not be able to achieve >50% on the total question set.
There is this idea that AI has to be perfect to be intelligent - but we consider Humans intelligent and they are not even close. So is it the ability to generate novel ideas? Prove theorems? Pass tests?
I am not arguing that rote memorization is intelligence, or that we have achieved it, but does anyone know what AGI actually.. is?
There's a specific singularity theory of AI that is very popular. Eliezer Yudkowsky helped popularize it among the Bay Area "rationalist" community, and it has this idea that AGI necessarily implies a self improving system that will quickly become a paperclip maximizer or other such dystopian or utopian world changing intelligence.
By that singularity definition, we're probably nowhere near AGI, but if we define it as something that is as good at text/information manipulation as the 50th percentile human? I think we're already there.
> both outputs of Claude Mythos, their (still) unreleased advanced model
That sentence gives the impression that Mythos might be released in the future. That's clearly not going to happen - it's already "released" in as much as selected, trusted partners can access it, and the rest of us get it in the form of Fable - which is Mythos but with filters that downgrade you if you try to use it for anything even remotely related to cybersecurity or biology.
(The other day Fable 5 downgraded me to Opus after I asked it to explain the difference between tusks and teeth.)
because as OP of the article points out, it's not a guaranteed hit with these models no matter how capable. they are stochastic (but not parrots), humans are too (but in a different way), and so there is a chance that the answer is wrong. If I wanted the most accurate answer I'd be confident in believing, I'd ask the most advanced model.
Now obviously you can and should retort with hallucination and confabulation rates from external and Ant's own reports per model (pretty sure more advanced models are good at lying better, not less) instead of going with dumb "more expensive more accurate" mental model, but general principle stands for me still AFAIK.
it's not exactly rational I admit, but if I'm going to base my own work and reasoning from an LLM I'm going with the best available. This seems to trip up most normies because they are too lazy or too greedy to pay up for premium access and see for themselves why most of us are both awed and afraid. Generally, I'm too biased and too deep in ML/DL cargo cult (been in it since 2016) to know if the skepticism and disdain for such usage is warranted.
In general, I think the tools are broadly toxic in a Dune-sense of making me think less for myself, because just as any HN-poster knows coding and doing mundane low-level stuff is necessary the same way doing stretches is necessary before any workout. The process itself is what keeps your brain strong and its gradients from veering into overfitting. I'm not overly bullish on the whole reaching for the stars ending with these things. Paradoxically, you using them eventually hobbles both you and the model, because you become dumber and then you bottleneck their ability to self-direct (broadly true for next Mythos/GPT-7).
Sorry for a long rant, was just anticipating some things I'd have to say for myself.
>They [anthropic] appear to have just told it to get some results and then strapped its nose to the grindstone until it found some.
it is fun how well this works.
i cant find the link immediately (will look and edit with it), but somewhere in the "hello there the jacobian conjecture is false thanx" thread, someone brought up a different conjecture breakthrough where the prompts were basically just repeated "no, keep going" until a result was found.
> i especially like "you should do a breakthrough". each prompt is less than ~20 words. makes me really question the whole "prompt engineering" stuff.
This is well past prompt engineering and into process engineering like six sigma. Just like in an early industrial revolution factory, we’re all still figuring out what works in the process of making stuff except this is so early that even simple things like “make this screw standardized” (or “no, keep going” in this case) is really high impact.
The degrees of freedom an LLM has is so large that we're going to be exploring their capabilities for decades, especially if they continue to get better. This is why IMO experts are always going to be better at LLMs in their field because they can force them LLM into processes (think prompt engineering -> CC dynamic workflows) that follow their work processes and get much better results out of them than “keep going.”
In response to your edit, you should check out Terry tao's chat gpt logs about the recent Jacobian result. The models are smart enough to brute force some things, but can cut to the meat much faster with good prompting
i read his, too. his replies are indeed more directed, but also quite short, unstructured, and natural sounding. if i recall, maybe 1 or 2 of his prompts exceeded 50(ish) words.
in my head, the comparison is the multi-paragraph prompts (borderline essays) i would read in various communities on reddit and similar forums, that people (often self-proclaimed "prompt engineers") said were "required" to get good output. or some of the prompts ive read in various logs that are like a thousand words of setup.
even looking back at the first prompts i was sending when i started to use chatgpt were (in hindsight) crazy long and full of unnecessary guidance/caveats/"ignore xyz"/etc.
> were (in hindsight) crazy long and full of unnecessary guidance
Not sure when you started. However: I would never judge the necessity of details provided 2 or 3 years ago based on results that the current models give.
I didn't use generative AI much until a couple months ago. My last employer had a copilot license that I dabbled in in 2024, and wasn't impressed with, and then I spent the latter half of 2025 and early 2026 budget traveling/hiking a lot. I started at a new company in May, and I've been astonished at how lazy I can be at prompting and still get impressive results with 2026 Claude Code.
I can paste entire failure logs with the word "why" lowercase, no question mark, and get into a productive chat session where it significantly speeds up the bug trace. I will paste the text from a groomed ticket with no editing or additional instructions into the chat and then give it a bit of feedback on the plan for a couple iterations.
I feel so vindicated in never spending time learning prompting as a specific skill, it really just took a couple more years and the models are really easy to interact with with simple natural language.
That second person stated that for many years they tried that particular graph problem on various AI models, starting with o1 and o3.
Its quite likely they now found the counterexample with a more serious prompt, and then for virality re-tried a few times with meme-prompts like "you should do a breakthrough", knowing that the model is capable of solving this particular one. Worst case the meme-prompts don't work and they share the real one they initially used.
>Its quite likely they now found the counterexample with a more serious prompt, and then for virality re-tried a few times with meme-prompts
i am not sure why this is "quite likely". it'd be pretty silly to get a mathematical breakthrough and then hide it for an undisclosed amount of time to get a few more likes on a tweet, when the impressive part is the breakthrough.
not saying your theory is impossible, but i think the simple answer is that the model is just smarter than o1 and o3.
and, in any case, the model ended up getting the result with the meme prompt and "keep going", which was what i find fun. just like how the crypto results were from prompts of, more or less, "keep going", and that's pretty damn cool.
You can open 10 tabs and prompt 10 times. We are talking about a few hours delay.
I agree with you that obviously no prompt engineering was needed just "solve this problem", but imagine it was you doing this problem with every model, wouldn't you have tested a new model with the best prompt you had from previous iterations, maybe with some partial previous results in it, exactly to maximize your probability for a mathematical breakthrough?
Same with cybersec. They're finding bugs a human could've found if they looked hard but humans don't look hard at 100% of the code and the LLM can, at high speed.
> I asked Claude for its thoughts, and it doesn’t mince words: “what makes this genuinely interesting — and, frankly, a little embarrassing for the field — is that none of the ingredients are exotic.” The TL;DR is that someone just did a much more thorough job applying all of our known tools. In short: the sort of things that attack AIs are wonderful at.

If you believe that matrix multiplication with random sampling is conscious, then you probably believe everything is conscious, like rocks.
Most people would expect that matrix multiplication is not conscious, and autocomplete is not conscious either.
We can't prove matrix multiplication isn't conscious, but it doesn't seem likely unless everything is conscious.

...which is nonsense: the gate simply, directly, selects the experts. There's nothing probabilistic about it.

Isn't G a learned probability?

"Surprisingly, we find that the current training setup does not elicit fundamentally new reasoning patterns. While RLVR-trained models outperform their base models at small k (e.g., k = 1), the base models achieve a higher pass@k score when k is large. Coverage and perplexity analyses show that the observed reasoning abilities originate from and are bounded by the base model. "
This paper is less dramatic than you think it is and really just re-explains what RLVR does.
Let's stipulate that what pretraining does is train next token prediction over a gigantic corpus. You can then sample from this distribution repeatedly (cf the Large Language Monkeys paper) and count how often it passes some deterministic verifier.
What GRPO-style RLVR does is precisely this, but then reward the trajectories which passed the verifier. These distributions are _by construction_ within the accessible output space of the pretrained model; you're reweighting the distribution so that pass@k goes up, because that's (for applications like programming) very useful. RLVR is about making sampling more efficient; the only new information being added to the system is the presence of the verifier, and note that you only get a reward when the verifier passes, so there's essentially no mechanism for "teaching new facts" here.
Ooh. This looks like an interesting paper and there were a couple of things in the intro that I found counter-intuitive. It'll take me a while to digest the whole thing.
> Coverage and perplexity analyses show that the observed reasoning abilities originate from and are bounded by the base model
On the face of it this seems unsurprising given the policy gradient term directly minimises this difference.
I don't have a good feel for how the output of an RLVR-trained model concretely differs from the base model. My guess would be there are a fairly small number of "forks" where the training creates a token flip that sends the model down a more useful path.
The fact that the straight paths between the forks resemble the base model would again be unsurprising since (a) those are exactly the right context to continue to elicit more output that's relevant to solving the problem (so not penalised by RLVR), and (b) preservation drops naturally out of the policy gradient term you add to limit catastrophic forgetting in the base model.
Low perplexity could be explained by the relative sparsity of the forks in the output stream, and/or by forks already having high entropy in the base model. That also aligns with the pass-at-high-k: yes it's doing more exploration without training but it's a bit of a monkeys-on-typewriters situation.
Lack of novelty is readily explained by the fact that you need some nonzero pass rate in the base model to actually get some useful training signal from RLVR. That's a limitation of contemporary RLVR techniques, not a limitation on post-training in general.
I think there's room in that forks-and-straights characterisation for the RLVR'd model to be doing something that looks a lot like computation, while having low perplexity vs the base model. I don't see anything in my admittedly incredibly shallow skim of the paper that refutes that.
VibeThinker 3B is highly problematic for the thesis expressed in that paper. There is no possible way it could derive its reasoning capabilities from a bag of 3B parameters alone.
> the model's output is the result of an optimisation process that rewarded behaviour that was useful, and that's fundamentally different
I'm not understanding, can you explain this more? How does it become more than a next token predictor? Isn't the post-training simply altering the sampled distribution? And isn't that distribution naturally occurring? It's the distribution of "useful" next token?
I think this is smart, it seems to me that the best way to use these models its to approach them as a next-token predictor instead of an intelligent entity. That's how I've gotten the best results from them and allows me to avoid some of the pitfalls people fall into by anthropromising them.
Exactly. They ARE "glorified autocomplete" in an ontological sense. That says nothing about capability or outcome. The people who come out swinging against that characterization usually ignore the whole ontological argument (which is...the entire point) and go after an outcome-based strawman.
Isn't the outcomes question the one that people actually care about in most contexts?
Depends. "Most" implies majority, and the majority of people are using these tools not for programming but in contexts where ontology is more relevant than capability (not that capability is irrelevant, but most people care, or are tricked into caring, far more about the former).
Sorry, what contexts are these?
Sorry, this discussion is too incommensurable for me.
I don't know about "most", but there are a lot of people treating it as somewhere between "magic oracle" and "new friend"
Not to mention people more worried about whether the AI is motivated to hurt us than what human motivations can do with something that can autocomplete its way through every possible attack vector of cryptographic systems most of use would prefer remain secure.
(tbf I think the "glorified autocomplete" still works surprisingly well for programming outcomes too. Autocomplete [and fuzzy search of reference material] actually is useful and often right and certainly can save time even when it's only suggesting the rest of the variable name. But you might not want to commit everything it suggests...)
My favorite analogy for LLMs is "an intellectual chain saw". It does one thing, well, but that isn't "cut wood". It's "cut". What it cuts will happily include limbs.
Whether an AI's operators lose control of it is an outcomes question.
I like glorified copy/paste frankensteined with find/replace.
But... These are also literally glorified autocomplete. Autoregressive language models are all autocomplete. It turns out that advanced enough autocomplete can do interesting stuff.
I generally like it still. It describes their failure modes pretty well, and in a way that most people already recognize. They're incomparably more complex, of course, but they are not intelligent and they are very much repeating what they've seen without any capability for factual accuracy.
Practically every other attempt at describing them leans too technical and unfamiliar (stochastic parrot) or too anthropomorphic (even describing them as "not like a human" gets people thinking in terms of humans, like how if I mention that your tongue is in your mouth all the time, using up almost all of the room, feeling your teeth and tasting itself, you're now uncomfortably aware of it and the numerous bumps on the surface).
You need to work from a reference that has both a shared understanding, and does not lead to problematic "if X has Y, and Z is like X, then Z has Y" seemingly-logical derived beliefs. "Spicy autocomplete" is a fairly safe starting point in both ways.
Which obviously raises the question of if we are just glorified autocomplete (or glorified pattern matching). After all, we evolved from things just trying to recognize the patterns for what will hurt us and what will cause pleasure.
The models themselves are indeed glorified autocomplete in terms of what they actually do (with things like agentic coding harnesses being required as a wrapper around them to make that internal autocomplete something more useful). Many people use this fact to critique LLMs, but many other common instances of people pointing out LLMs' apparent lack of intelligence actually come from people not understanding that the model is a glorified autocomplete underneath whatever interface people access them through, and the interface isn't providing the underlying model all the information they assume it would, making it seem less intelligent than it actually is.
My mental model is this:
There is a vast ocean of human knowledge, far beyond the capacity of any human brain, even within specialised fields.
Books helped "plug the gaps" in our knowledge, increasing the scope that a single human mind can encompass.
Web search engines did the same thing, but more and faster.
LLMs are like search engines on steroids, essentially a research librarian that operates at 1,000x human speed and can "in context" locate relevant information, adapting it to fit the hole it needs to go into as well.
It feels less like discovering new theorems, but instead having direct access to all theorems, which is hugely valuable in itself.
I.e.: the recent counterexamples to open conjectures has largely been about the AIs "trawling through all the things" and scraping together every bit of human-generated knowledge ever produced that is relevant to the conjecture.
Conversely, in the past, we had to "make do" with sub-standard solutions where the problem had been solved, but finding every relevant solution in the ocean of knowledge was prohibitively time consuming.
In some sense, LLMs will "raise the floor" in what is considered the minimum level of quality of a solution, where even throwaway / toy designs will now start applying every bit of accumulated wisdom instead of just some of it.
We have mechanised attention.
> AGI is already here
I feel like there has been a ton of noise about this, but frankly, no one has actually defined what AGI means. I feel like the goal post is constantly shifting.
Take for example Humanity's Last Exam. It is so broad and complex that while an individual in a specific field might be able to answer their specific area of questions, they certainly would not be able to achieve >50% on the total question set.
There is this idea that AI has to be perfect to be intelligent - but we consider Humans intelligent and they are not even close. So is it the ability to generate novel ideas? Prove theorems? Pass tests?
I am not arguing that rote memorization is intelligence, or that we have achieved it, but does anyone know what AGI actually.. is?
There's a specific singularity theory of AI that is very popular. Eliezer Yudkowsky helped popularize it among the Bay Area "rationalist" community, and it has this idea that AGI necessarily implies a self improving system that will quickly become a paperclip maximizer or other such dystopian or utopian world changing intelligence.
By that singularity definition, we're probably nowhere near AGI, but if we define it as something that is as good at text/information manipulation as the 50th percentile human? I think we're already there.
> both outputs of Claude Mythos, their (still) unreleased advanced model
That sentence gives the impression that Mythos might be released in the future. That's clearly not going to happen - it's already "released" in as much as selected, trusted partners can access it, and the rest of us get it in the form of Fable - which is Mythos but with filters that downgrade you if you try to use it for anything even remotely related to cybersecurity or biology.
(The other day Fable 5 downgraded me to Opus after I asked it to explain the difference between tusks and teeth.)
Genuine question here, why would you ask Fable to explain the difference between tusks and teeth? That's a task that can probably be handled by Haiku.
It's the default when I pop open the Claude iPhone app, I usually don't bother to switch it.
because as OP of the article points out, it's not a guaranteed hit with these models no matter how capable. they are stochastic (but not parrots), humans are too (but in a different way), and so there is a chance that the answer is wrong. If I wanted the most accurate answer I'd be confident in believing, I'd ask the most advanced model.
Now obviously you can and should retort with hallucination and confabulation rates from external and Ant's own reports per model (pretty sure more advanced models are good at lying better, not less) instead of going with dumb "more expensive more accurate" mental model, but general principle stands for me still AFAIK.
it's not exactly rational I admit, but if I'm going to base my own work and reasoning from an LLM I'm going with the best available. This seems to trip up most normies because they are too lazy or too greedy to pay up for premium access and see for themselves why most of us are both awed and afraid. Generally, I'm too biased and too deep in ML/DL cargo cult (been in it since 2016) to know if the skepticism and disdain for such usage is warranted.
In general, I think the tools are broadly toxic in a Dune-sense of making me think less for myself, because just as any HN-poster knows coding and doing mundane low-level stuff is necessary the same way doing stretches is necessary before any workout. The process itself is what keeps your brain strong and its gradients from veering into overfitting. I'm not overly bullish on the whole reaching for the stars ending with these things. Paradoxically, you using them eventually hobbles both you and the model, because you become dumber and then you bottleneck their ability to self-direct (broadly true for next Mythos/GPT-7).
Sorry for a long rant, was just anticipating some things I'd have to say for myself.
If you're paying a flat monthly rate, unused tokens are wasted tokens.
>They [anthropic] appear to have just told it to get some results and then strapped its nose to the grindstone until it found some.
it is fun how well this works.
i cant find the link immediately (will look and edit with it), but somewhere in the "hello there the jacobian conjecture is false thanx" thread, someone brought up a different conjecture breakthrough where the prompts were basically just repeated "no, keep going" until a result was found.
edit: https://chatgpt.com/share/6a60b2eb-0b64-83ee-9c76-7931ca1de0...
i especially like "you should do a breakthrough". each prompt is less than ~20 words. makes me really question the whole "prompt engineering" stuff.
> i especially like "you should do a breakthrough". each prompt is less than ~20 words. makes me really question the whole "prompt engineering" stuff.
This is well past prompt engineering and into process engineering like six sigma. Just like in an early industrial revolution factory, we’re all still figuring out what works in the process of making stuff except this is so early that even simple things like “make this screw standardized” (or “no, keep going” in this case) is really high impact.
The degrees of freedom an LLM has is so large that we're going to be exploring their capabilities for decades, especially if they continue to get better. This is why IMO experts are always going to be better at LLMs in their field because they can force them LLM into processes (think prompt engineering -> CC dynamic workflows) that follow their work processes and get much better results out of them than “keep going.”
In response to your edit, you should check out Terry tao's chat gpt logs about the recent Jacobian result. The models are smart enough to brute force some things, but can cut to the meat much faster with good prompting
i read his, too. his replies are indeed more directed, but also quite short, unstructured, and natural sounding. if i recall, maybe 1 or 2 of his prompts exceeded 50(ish) words.
in my head, the comparison is the multi-paragraph prompts (borderline essays) i would read in various communities on reddit and similar forums, that people (often self-proclaimed "prompt engineers") said were "required" to get good output. or some of the prompts ive read in various logs that are like a thousand words of setup.
even looking back at the first prompts i was sending when i started to use chatgpt were (in hindsight) crazy long and full of unnecessary guidance/caveats/"ignore xyz"/etc.
> were (in hindsight) crazy long and full of unnecessary guidance
Not sure when you started. However: I would never judge the necessity of details provided 2 or 3 years ago based on results that the current models give.
I didn't use generative AI much until a couple months ago. My last employer had a copilot license that I dabbled in in 2024, and wasn't impressed with, and then I spent the latter half of 2025 and early 2026 budget traveling/hiking a lot. I started at a new company in May, and I've been astonished at how lazy I can be at prompting and still get impressive results with 2026 Claude Code.
I can paste entire failure logs with the word "why" lowercase, no question mark, and get into a productive chat session where it significantly speeds up the bug trace. I will paste the text from a groomed ticket with no editing or additional instructions into the chat and then give it a bit of feedback on the plan for a couple iterations.
I feel so vindicated in never spending time learning prompting as a specific skill, it really just took a couple more years and the models are really easy to interact with with simple natural language.
That second person stated that for many years they tried that particular graph problem on various AI models, starting with o1 and o3.
Its quite likely they now found the counterexample with a more serious prompt, and then for virality re-tried a few times with meme-prompts like "you should do a breakthrough", knowing that the model is capable of solving this particular one. Worst case the meme-prompts don't work and they share the real one they initially used.
>Its quite likely they now found the counterexample with a more serious prompt, and then for virality re-tried a few times with meme-prompts
i am not sure why this is "quite likely". it'd be pretty silly to get a mathematical breakthrough and then hide it for an undisclosed amount of time to get a few more likes on a tweet, when the impressive part is the breakthrough.
not saying your theory is impossible, but i think the simple answer is that the model is just smarter than o1 and o3.
and, in any case, the model ended up getting the result with the meme prompt and "keep going", which was what i find fun. just like how the crypto results were from prompts of, more or less, "keep going", and that's pretty damn cool.
You can open 10 tabs and prompt 10 times. We are talking about a few hours delay.
I agree with you that obviously no prompt engineering was needed just "solve this problem", but imagine it was you doing this problem with every model, wouldn't you have tested a new model with the best prompt you had from previous iterations, maybe with some partial previous results in it, exactly to maximize your probability for a mathematical breakthrough?
Not everything is a conspiracy
Oh boy. The human here is effectively assuming the role of a Magic 8 Ball…
What a weird species of halting problem…
Same with cybersec. They're finding bugs a human could've found if they looked hard but humans don't look hard at 100% of the code and the LLM can, at high speed.
Could send random characters along with 'keep going' and it would change nothing, the seed is whats causing deviation between these responses.
The prompt used to get this result is pretty crazy.

> I asked Claude for its thoughts, and it doesn’t mince words: “what makes this genuinely interesting — and, frankly, a little embarrassing for the field — is that none of the ingredients are exotic.” The TL;DR is that someone just did a much more thorough job applying all of our known tools. In short: the sort of things that attack AIs are wonderful at.
