It's just filled to the brim with relations between things. It's good at searching a very large meaning space and create correlations. What it does is to cover great distances and find related things in that large space which needs a long time and large corpus of knowledge to find the connection.
This is not intelligence. It's just a good correlation engine with a very big albeit lossy database of things.
Intelligence is compression, compression requires subtraction, and for some reason LLMs are not good at subtracting. To create a coherent model you kinda have to subtract correlations until only the essential parts are still there.
What I don't understand is why LLMs haven't been able to do this yet, if it's the harness or some orchestration layer above the LLM that is needed. Because fundamentally if you can identify correlations then it's just another small step to prioritize and remove lower value or irrelevant correlations.
I wonder if what's needed is to introduce subtraction tokens in some sense, and in post-training reward the model on that.
Intelligence is compression? What do you mean? Intuitively that doesn't seem right.
>What I don't understand is why LLMs haven't been able to do this yet
LLMs are just trained on what humans have said. Why is it surprising that it's still not possible to reconstruct the intelligence that wrote all that by working backwards? Think of your own work experience. When you look at a piece of code, say, are you always able to discern why the person did what they did, just from the code, with no additional context?
I guess they mean that intelligence is being able to hold models (compressed versions of reality) internally and use them to make predictions with a probability better than chance. That last part is the definition of information.
I find that highly questionable as a general description of what intelligence does. That's more like a description of a general knowledge base. When I think of someone intelligent, I think of someone who's able to draw unexpected connections between seemingly unrelated facts. In the broadest possible terms, I'd call it the ability to make abstractions and analogies. This is not just compression, but the ability to mentally operate on webs of meaning.
Doing those things also contributes to compression. I do recommend reading up on it, it's perhaps a little overstated for what people intuitively consider the two concepts but it's been quite well explored and has held up pretty well in practice.
Intelligence is compression
That’s a controversial statement.
I've heard that expression before, but I don't think it can be presented and stated so matter of factly. Where does that put bzip?
bzip is not very intelligent, true, but it does develop some model of its input. It's not like there's a linear relationship between between compression ratio and IQ or anything.
Abstraction is compression, and abstraction is definitely a core component of intelligence.
Creating the model takes intelligence, but running it doesn’t. I think the point everybody’s revolving around is that the transformer model is an absurdly inefficient and low-fidelity approximation of a system that acts, observes consequences, and incorporates that feedback going forward.
The issue isn’t really harness vs. no harness. IMO it’s about the lack of an internally generated sense of what to attend to. Yes, the KV cache accumulates state and its “attention” (if you can even call it that) changes with context. We’ve even managed to /kinda/ close the loop with agentic tool calling and ‘memory’ systems, but these just close the loop at the level of behavior rather than disposition. All agentic harnesses do is make an LLM responsive to the consequences of its actions without changing the tendencies by which it determines what to retain or avoid.
The ghost you can’t escape from at this point is the origin of that relevance. Where does the pull toward one thing mattering over another actually come from? If you ran Fable 5 on a Turing machine and rewound the tape to the exact same state with the exact same input (incl. PRNG seed), it would spit out the same output every time.
Everyone’s trying to outrun this problem by training more often or increasing model sizes. But all this does is inform your model, from the outside(!), what constitutes a better state. The thing that’s actually doing the determining remains unchanged. Congratulations, you’ve scaled the transition function and tape of your Turing machine until it requires every watt generated by ERCOT, and it still cannot, for the life of it, tell you why it should give a shit.
A trained model generating output from weights, a seed, and some context effectively has next-state that’s a total function of those three things. Whatever behavior appears as ‘selecting what is relevant’ is, underneath, just a transition rule executing, no matter how sophisticated or creative the output looks. It can be fully accounted for by what was fixed before it started executing. Which means whatever criterion it uses for determining what matters was inherited from a structure that was already in place before it encountered the situation.
No amount of pruning or post-training can fix this. These approaches just replace one externally supplied criterion with another. For a system to be truly adaptable, there would have to be some criterion by which it treats one possible change as preferable to another, and that criterion itself would have to come from... somewhere. You can even change your conception of ‘improvement’ (e.g. parameter count, harnesses, self-modification, hell, even its ability to spit out shitty best-selling romance novels onto Amazon) and you still haven’t explained where the normative distinction comes from. Every layer of this problem has its root in a preference that was supplied from somewhere else.
I genuinely don’t know if this issue bottoms out anywhere, at least for the way we currently build these systems. Perhaps the solution is still computable, maybe? Who knows what that would even look like. But I’m fairly confident that it isn’t a bigger tape. I hope nobody solves this in the near future because, well, I’d like to have a job...
You're so close... And where is the magic "uncomputable spark" located inside of you? If you say analog thermodynamic noise - then ok, if we use true thermodynamic RNG for LLM activation function, will that meet the criteria? But what if super determinism is the law of the land? Then nobody is anything but computable from priors...
The very fact that it is able to search within a meaning-space demonstrates that it understands semantics, to some extent. Philosophically, that is profound, for something that is just one big matrix multiplication. Drawing connections between things in meaning-space is surely a facet of intelligence.
It’s not intelligence if you are the one who gives the correlations to the model in the pre-training. It’s Word2Vec, applied. Model doesn’t learn anything. You embed these correlations and build it from there. It just searches the space.
As my AI professor said in the first lecture: “All AI is advanced search”.
Okay, I guess you're right that its ability to do this is just correlational, which doesn't imply it has any understanding. However, you have to conclude that some tasks which we used to believe required intelligence don't actually require any, which is disconcerting.
No, what I would say is the tasks which are handled in a passable manner by LLMs can be mathematically modeled with some reasonable accuracy.
Many things are predicted by models in our planet. From weather to production and material science. Building the model needs intelligence, running the model does not.
The person who came up with the formulae for CFD was intelligent. The computer running the model is not. Same for LLMs, chess engines, engine ECUs and financial prediction systems.
Again, for the example’s sake; the person who came up with an algorithm is intelligent. The model mixing its training data to emit something similar is not.
This starts to feel like you're defining the word intelligence out of any meaning and out of any way we apply that word.
So when LLMs can do all human knowledge work, and do it better than humans, we'll be in the mines listening to you go on about how it's actually just autocomplete or just math, a distinction that apparently means nothing.
> This starts to feel like you're defining the word intelligence out of any meaning and out of any way we apply that word.
No.

With a big "if" attached to it. People were saying "computers will program themselves in the near future" for, checks notes, 24 years now, as far as I'm aware.
We're constantly building new knowledge and understanding things better than olden days. These models just compress our knowledge and light the blind corners we can't see well. I don't say they are useless, but I say that these things are overhyped.
All they can do is regurgitate human knowledge packed into them and highlight some long-distance correlations between items, which is useful in itself, but it can't jump to somewhere where it's not present its training data, but that's something humans and only humans can do.
Locked in a dark room with no sensory organs, humans couldn't do that.
Most of what you said reads to me as denial.
An unconscious unintelligent but persistent trial and error process created us. We created LLMs. LLMs may create the next thing before we do - hard to say. They don't have all the cognitive tools we have yet, but they still outperform in some areas. As the cognitive playing field levels, I expect you will come to eat your words..
I get what you're saying. The thing itself is just math. I'll just say it depends on how you define intelligence. If at some point we're be able to simulate a human brain with 100% accuracy, I would say that it is intelligent, it sounds like you would not. (I don't mean to imply consciousness or personhood or anything else by "intelligent".)
For me intelligence is a fairly clean-cut concept, and is somewhat inseparable from consciousness itself.
Briefly, any intelligent creature has internal stochastic processes like sensory inputs and feelings to a certain degree. These stochastic inputs and the creature's own actions change the creature in subtle or profound ways. An LLM has no such processes. You push inputs to the same static model, sans temperature which is just a randomness slider.
Considering the model even doesn't see the words and work on matrices of numbers is even more telling. One needs to add "tools" and other "experts" to overcome the shortcomings caused by this modus operandi.
I can call the algorithm/model smart as in a smartwatch. It can mimic certain things well while having none of the underlying foundation beneath it, or redirect some of the things to correct tools to get deterministic and accurate results if it can't evaluate the query inside its own network in a sane manner.
Coming to your question, "simulating a brain" in a static manner would not make that simulation intelligent, but if you can "wire" it completely and let it evolve by itself, now we're entering a territory I have not spent enough time for thinking it through.
Oh, as I said "I don't know", an LLM doesn't know what it doesn't know, and can't self correct itself which are required capabilities for understanding something. It just generates something statistically viable via its network.
Your text reads much better if you replace word 'intelligence' with 'text generator with some randomness built in'.
This is because you goal is to state how models are not intelligent, but you couldn't attack the generated text itself, so you created a little rider, attached it to the model, and then you attacked the raider.
But, even in that you failed. You compared the source of human randomness in text generation, and called it 'profound' and implied that it is exactly the source of true intelligence. But, then, the temperature, the similar thing in model was "just a randomness slider". Double standard.
A logical fallacy free attack on LLMs would be to show a prompt, and then the response generated by this prompt, where it would be shown that only an entity with no intelligence would generate such a response. Yet, attacks like this are not written here anymore.
I wonder why.
They perform tasks too. They execute functions. This has real world implications beyond search.
