I found the aeticle in a post on the fediverse, and I can’t find it anymore.
The reaserchers asked a simple mathematical question to an LLM ( like 7+4) and then could see how internally it worked by finding similar paths, but nothing like performing mathematical reasoning, even if the final answer was correct.
Then they asked the LLM to explain how it found the result, what was it’s internal reasoning. The answer was detailed step by step mathematical logic, like a human explaining how to perform an addition.
This showed 2 things:
-
LLM don’t “know” how they work
-
the second answer was a rephrasing of original text used for training that explain how math works, so LLM just used that as an explanation
I think it was a very interesting an meaningful analysis
Can anyone help me find this?
EDIT: thanks to @theunknownmuncher @lemmy.world https://www.anthropic.com/research/tracing-thoughts-language-model its this one
EDIT2: I’m aware LLM dont “know” anything and don’t reason, and it’s exactly why I wanted to find the article. Some more details here: https://feddit.it/post/18191686/13815095
I don’t know how I work. I couldn’t tell you much about neuroscience beyond “neurons are linked together and somehow that creates thoughts”. And even when it comes to complex thoughts, I sometimes can’t explain why. At my job, I often lean on intuition I’ve developed over a decade. I can look at a system and get an immediate sense if it’s going to work well, but actually explaining why or why not takes a lot more time and energy. Am I an LLM?
I agree. This is the exact problem I think people need to face with nural network AIs. They work the exact same way we do. Even if we analysed the human brain it would look like wires connected to wires with different resistances all over the place with some other chemical influences.
I think everyone forgets that nural networks were used in AI to replicate how animal brains work, and clearly if it worked for us to get smart then it should work for something synthetic. Well we’ve certainly answered that now.
Everyone being like “oh it’s just a predictive model and it’s all math and math can’t be intelligent” are questioning exactly how their own brains work. We are just prediction machines, the brain releases dopamine when it correctly predicts things, it self learns from correctly assuming how things work. We modelled AI off of ourselves. And if we don’t understand how we work, of course we’re not gonna understand how it works.

Formatting might be off on some of these, had to convert some papers to text as some were only scanned and I couldn’t be bothered writing it all out by hand:
And longer excepts on the similarities of AI neural networks to biological brains, more specifically human children, in the pursuit of study with improving learning and education development. Super interesting papers that are easily accessible to anyone:
I personally think there are plenty of examples out there in neuroscience and computer science papers let alone what other fields are starting to discover with the use of AI. In my opinion it should be of no surprise and quite clear how replicating a mechanism of self-adapting logic would create behaviours that we can find directly within ourselves.
Let me know if this is enough to prove my point, but I think I’m tired of reading papers for a bit.
I don’t think this is a fair way of summarizing it. You’re making it sound like we have AGI, which we do not have AGI and we may never have AGI.
Let’s get something straight, no I’m not saying we have our modern definition of AGI but we’ve practically got the original definition coined before LLMs were a thing. Which was that the proposed AGI agent should maximise “the ability to satisfy goals in a wide range of environments”. I personally think we’ve just moved the goal posts a bit.
Wether we’ll ever have thinking, rationalised and possibly conscious AGI is beyond the question. But I do think current AI is similar to existing brains today.
Do you not agree that animal brains are just prediction machines?
That we have our own hallucinations all the time? Think visual tricks, lapses in memory, deja vu, or just the many mental disorders people can have.
Do you think our brain doesn’t follow path of least resistance in processing? Or do you think our thoughts comes from elsewhere?
I seriously don’t think animal brains or human to be specific are that special that nurural networks are beneath. Sure people didn’t like being likened to animals but it was the truth, and I as do many AI researches, liken us to AI.
AI is primitive now, yet it can still pass the bar, doctors exams, compute complex physics problems and write a book (soulless as it may be like some authors) in less than a few seconds.
Whilst we may not have AGI the question was about math. The paper questioned how it did 36+59 and it did things in an interesting way where it half predicted what the tens column would be and ‘knew’ what the units column was, then put it together. Although thats not how I or even you may do it there are probably people who do it similar.
All I argue is that AI is closer to how our brains think, and with our brains being irrational quite often it shouldn’t be surprising that AI nural networks are also irrational at times.
That was not the definition of AGI even back before LLMs were a thing.
That’s doing a disservice to AGI.
That’s doing a disservice to human brains. Humans are sentient, LLMs are not sentient.
I don’t really agree with you.
LLMs are damn impressive, but they are very clearly not AGI, and I think that’s always worth pointing out.
The first person to be recorded talking about AGI was Mark Gubrud. He made that quote above, here’s another:
As UGI largely encompasses AGI we could easily argue that if modern LLMs are beginning to fit the description of UGI then it’s fullfilling AGI too. Although AGI’s definition in more recent times has become more nuanced to replicating a human brain instead, I’d argue that that would degrade the AI trying to replicate biology.
I don’t beleive it’s a disservice to AGI because AGI’s goal is to create machines with human-level intelligence. But current AI is set to surpase collective human intelligence supposedly by the end of the decade.
And it’s not a disservice to biological brains to summarise them to prediction machines. They work, very clearly. Sentience or not if you simulated every atom in the brain it will likely do the same job, soul or no soul. It just brings the philosophical question of “do we have free will or not?” And “is physics deterministic or not”. So much text exists on the brain being prediction machines and the only time it has recently been debated is when someone tries differing us from AI.
I don’t believe LLMs are AGI yet either, I think we’re very far away from AGI. In a lot of ways I suspect we’ll skip AGI and go for UGI instead. My firm opinion is that biological brains are just not effective enough. Our brains developed to survive the natural world and I don’t think AI needs that to surpass us. I think UGI will be the equivalent of our intelligence with the fat cut off. I believe it only resembles our irrational thought patterns now because the fat hasn’t been striped yet but if something truely intelligent emerges, we’ll probably see these irrational patterns cease to exist.
Two things being difficult to understand does not mean that they are the exact same.
Maybe work is the wrong word, same output. Just as a belt and chain drive does the same thing, or how fluorescent, incandescent or LED lights produce light even though they’re completely different mechanisms.
What I was saying is that one is based on the other, so similar problems like irrational thought even if the right answer is conjured shouldn’t be surprising. Although an animal brain and nural network are not the same, the broad concept of how they work is.

Even if LLM “neurons” and their interconnections are modeled to the biological ones, LLMs aren’t modeled on human brain, where a lot is not understood.
The first thing is that how the neurons are organized is completely different. Think about the cortex and the transformer.
Second is the learning process. Nowhere close.
The fact explained in the article about how we do math, through logical steps while LLMs use resemblance is a small but meaningful example. And it also shows that you can see how LLMs work, it’s just very difficult
I agree, but I’m not sure it matters when it comes to the big questions, like “what separates us from the LLMs?” Answering that basically amounts to answering “what does it mean to be human?”, which has been stumping philosophers for millennia.
It’s true that artificial neurons are significant different than biological ones, but are biological neurons what make us human? I’d argue no. Animals have neurons, so are they human? Also, if we ever did create a brain simulation that perfectly replicated someone’s brain down to the cellular level, and that simulation behaved exactly like the original, I would characterize that as a human.
It’s also true LLMs can’t learn, but there are plenty of people with anterograde amnesia that can’t either.
This feels similar to the debates about what separates us from other animal species. It used to be thought that humans were qualitatively different than other species by virtue of our use of tools, language, and culture. Then it was discovered that plenty of other animals use tools, have language, and something resembling a culture. These discoveries were ridiculed by many throughout the 20th century, even by scientists, because they wanted to keep believing humans are special in some qualitative way. I see the same thing happening with LLMs.
You’re definitely overselling how AI works and underselling how human brains work here, but there is a kernel of truth to what you’re saying.
Neural networks are a biomimicry technology. They explicitly work by mimicking how our own neurons work, and surprise surprise, they create eerily humanlike responses.
The thing is, LLMs don’t have anything close to reasoning the way human brains reason. We are actually capable of understanding and creating meaning, LLMs are not.
So how are they human-like? Our brains are made up of many subsystems, each doing extremely focussed, specific tasks.
We have so many, including sound recognition, speech recognition, language recognition. Then on the flipside we have language planning, then speech planning and motor centres dedicated to creating the speech sounds we’ve planned to make. The first three get sound into your brain and turn it into ideas, the last three take ideas and turn them into speech.
We have made neural network versions of each of these systems, and even tied them together. An LLM is analogous to our brain’s language planning centre. That’s the part that decides how to put words in sequence.
That’s why LLMs sound like us, they sequence words in a very similar way.
However, each of these subsystems in our brains can loop-back on themselves to check the output. I can get my language planner to say “mary sat on the hill”, then loop that through my language recognition centre to see how my conscious brain likes it. My consciousness might notice that “the hill” is wrong, and request new words until it gets “a hill” which it believes is more fitting. It might even notice that “mary” is the wrong name, and look for others, it might cycle through martha, marge, maths, maple, may, yes, that one. Okay, “may sat on a hill”, then send that to the speech planning centres to eventually come out of my mouth.
Your brain does this so much you generally don’t notice it happening.
In the 80s there was a craze around so called “automatic writing”, which was essentially zoning out and just writing whatever popped into your head without editing. You’d get fragments of ideas and really strange things, often very emotionally charged, they seemed like they were coming from some mysterious place, maybe ghosts, demons, past lives, who knows? It was just our internal LLM being given free rein, but people got spooked into believing it was a real person, just like people think LLMs are people today.
In reality we have no idea how to even start constructing a consciousness. It’s such a complex task and requires so much more linking and understanding than just a probabilistic connection between words. I wouldn’t be surprised if we were more than a century away from AGI.
Maybe I am over selling current AI and underselling our brains. But the way I see it is that the exact mechanism that allowed intelligence to flourish within ourselves exists with current nural networks. They are nowhere near being AGI or UGI yet but I think these tools alone are all that are required.
The way I see it is, if we rewound the clock far enough we would see primitive life with very basic nural networks beginning to develop in existing multicellular life (something like jellyfish possibly). These nural networks made from neurons neurotransmitters and synapses or possibly something more primitive would begin forming the most basic of logic over centuries of evolution. But it wouldn’t reassemble anything close to reason or intelligence, it wouldn’t have eyes, ears or any need for language. At first it would probably spend its first million years just trying to control movement.
We know that this process would have started from nothing, nural networks with no training data, just a free world to explore. And yet over 500 million years later here we are.
My argument is that modern nural networks work the same way that biological brains do, at least the mechanism does. The only technical difference is with neurotransmitters and the various dampening and signal boosting that can happen along with nuromodulation. Given enough time and enough training, I firmly believe nural networks could develop reason. And given external sensors it could develop thought from these input signals.
I don’t think we would need to develop a consciousness for it but that it would develop one itself given enough time to train on its own.
A large hurdle that might arguably be a good thing, is that we are largely in control of the training. When AI is used it does not learn and alter itself, only memorising things currently. But I do remember a time when various AI researchers allowed earlier models to self learn, however the internet being the internet, it developed some wildly bad habits.
If all you’re saying is that neural networks could develop consciousness one day, sure, and nothing I said contradicts that. Our brains are neural networks, so it stands to reason they could do what our brains can do. But the technical hurdles are huge.
You need at least two things to get there:
1 is hard because a single brain alone is about as powerful as a significant chunk of worldwide computing, the gulf between our current power and what we would need is about… 100% of what we would need. We are so woefully under resourced for that. You also need to solve how to power the computers without cooking the planet, which is not something we’re even close to solving currently.
2 means that we can’t just throw more power or training at the problem. Modern NN modules have an underlying theory that makes them work. They’re essentially statistical curve-fitting machines. We don’t currently have a good theoretical model that would allow us to structure the NN to create a consciousness. It’s not even on the horizon yet.
Those are two enormous hurdles. I think saying modern NN design can create consciousness is like Jules Verne in 1867 saying we can get to the Moon with a cannon because of “what progress artillery science has made in the last few years”.
Moon rockets are essentially artillery science in many ways, yes, but Jules Verne was still a century away in terms of supporting technologies, raw power, and essential insights into how to do it.
We’re on the same page about consciousness then. My original comment only pointed out that current AI have problems that we have because they replicate how we work and it seems that people don’t like recognising that very obvious fact that we have the exact problems that LLMs have. LLMs aren’t rational because we inherently are not rational. That was the only point I was originally trying to make.
For AGI or UGI to exist, massive hurdles will need to be made, likely an entire restructuring of it. I think LLMs will continue to get smarter and likely exceed us but it will not be perfect without a massive rework.
Personally and this is pure speculation, I wouldn’t be surprised if AGI or UGI is only possible with the help of a highly advanced AI. Similar to how microbiologist are only now starting to unravel protein synthesis with the help of AI. I think the shear volume of data that needs processing requires something like a highly evolved AI to understand, and that current technology is purely a stepping stone for something more.
We don’t have the same problems LLMs have.
LLMs have zero fidelity. They have no - none - zero - model of the world to compare their output to.
Humans have biases and problems in our thinking, sure, but we’re capable of at least making corrections and working with meaning in context. We can recognise our model of the world and how it relates to the things we are saying.
LLMs cannot do that job, at all, and they won’t be able to until they have a model of the world. A model of the world would necessarily include themselves, which is self-awareness, which is AGI. That’s a meaning-understander. Developing a world model is the same problem as consciousness.
What I’m saying is that you cannot develop fidelity at all without AGI, so no, LLMs don’t have the same problems we do. That is an entirely different class of problem.
Some moon rockets fail, but they don’t have that in common with moon cannons. One of those can in theory achieve a moon landing and the other cannot, ever, in any iteration.
