Earlier quoted context omitted.

humans reasoned before language but lacked the ability to store and transmit it. Later advanced humans developed abstract reasoning once lingustistic library became sufficiently description of reality. But this is not how we reason from first princples. Language is one of our tools we developed to STORE reasoning, not create it. LLMs excel at uncompressing and interpreting that stored reasoning.

> humans reasoned before language That's an interesting supposition. Are you assuming language didn't exist before it was written? Language and meaning are, if you squint, pretty ancient and have roots in things like birdsong. It could be that ur-semantics predates our species as a whole.

It’s pretty clear that animals that don’t use a system of language are capable of reasoning. No need to over complicate things.

I'll admit that I find this discussion a bit navel-gazy. It has become a question of semantics not a question of actual functionality. The question has become "what do we mean when we use the word 'reasoning'" which is uninteresting. Dijkstra said[1] "... the question whether computers can think. The question is just as relevant and just as meaningful as the question whether submarines can swim." I don't see a clear…

I believe Djikstra's quote has long been taken out of context. It was a criticism of other computer scientists anthropomorphizing machines and applying human concepts like thinking and reasoning to them. Djikstra wasn't saying it's functionally the same so it's just a semantic quibble. He was saying those words don't apply to machines. Just like we don't say submarines swim because that's how animals move through wat…

I posted a link to the original context.

I don't know whether you are saying that I have taken it out of context or a more general statement of how other people have interpreted the quote.

To me it is quite clear -- the question of whether machines can reason is just as meaningful as the question as to whether submarines can swim, which is to say not at all meaningful. Can a submarine accomplish by other means what a fish accomplishes by swimming? If so, then what are we talking about?

Can an LLM accomplish by other means what a human accomplishes by "reasoning"? If so, then what are we talking about?

The article is heavily leaning on the paper "The Illusion of Thinking" [1].

It could be boiled down to: in 2025 this paper showed that "thought traces" in the models of the time could sometimes be inaccurate or misleading. Today they still might be, although OpenAI says actually they are accurate for their modern models, (based on internal research, rather than published research).

If anyone is interested in visualizing AI reasoning, I made flame graphs of Sonnet thinking output tokens which are colored and organized by purpose, for example, verification reasoning is purple and error correction reasoning is purple. [0] I asked the model to solve the same problem with the same prompt 5 times so you can see the differences in reasoning granted the coding agent sets the model temperature very high.

I won't get into the metaphysics of reasoning, however, the Sonnet is using an OODA loop. The difference which hasn't been gapped is that human reason and imagination (in the sense of Mr. Rogers' Neighborhood) can predict the consequences of the actions we take.

This ability to loop is much, much wider in Opus 5 than Opus 4.. I had to strain to get Opus 4. to do the wider OODA loop but Opus 5 does it out of the box. I needed to throw out all existing instructions, skills, guidance, moving from 4-* to 5.

> I'll admit that I find this discussion a bit navel-gazy. It has become a question of semantics not a question of actual functionality Ah, so you're more in the Investor mindset than the Scientist mindset. All you care about is results, not how it got there. There's a whiff of "hey, it's magic!" to that.

No, that's stupid.

The question of how LLMs (and "LRM"'s, an unfortunate and by the article's own admission, already outdated term) accomplish what they accomplish is fascinating. The question of whether they reason is meaningless. Most of the article is about the latter, with tiny tiny tiny bits of the former.

A lot of bias here around non-extended theories of cognition.

We're already well past the point of trying to correspond the internal "brain chemistry" of an LLM to a thing called "reasoning". True reasoning, if there even is such a term, is very clearly, empirically and historically, based in tool use and capability use. If you create an abstraction like lean, and programming languages to brute force, and systems to integrate with, that expands what the possibility of "intelligence" is.

There's further places to take this including the claim that intelligence lives "outside" the subject - fine, we can or can't debate that. Even if we drop that question, it's pretty clear that the agent doesn't need to have deep intrinsic structures of XYZ, if it can just attach to tools and compose them to achieve results.

For example, I've said before that a well known fact of LLMs is that they steer their tokens to the right input distribution, that's why they yap so much in reasoning (this has been proven in studies). At the same time, don't mistake that for the whole process. Are they steering themselves to the entire a priori reasoning chain, or are they scaffolding with intermediate experiments and results, writing them to memory notepads, etc. etc.

That changes the metric of intelligence you're trying to measure.

And no I'm not saying, "OK, then have the LLM use only tokens, no tool calling, no nothing". I mean, we can do that, sure. But any intelligent agent has to interact with the world - and my claim is that maximally intelligent agents won't put effort into a priori reasoning, but rather a more balanced approach that outsources said "intelligence" through abstractions.

The more I read about LLMs and more complex ML in general, the more I realize nobody really knows what is going on.

I took a "Deep Learning" CS class in college back when it was in its early stages. I doubt the field is still called that now, but it was the subset of ML that has been rebranded as AI; includes LLMs, image generation, image recognition, etc.

Like any class, it was confusing at first, but when I eventually grasped the math behind what we were doing, and of course the visual representations of different elements to show lots of iterations of this math, it grounded the science for me, and I would hardly say people don't know what is going on. It only began to feel that way when it got a ton of hype and people jumping on the bandwagon who truly didn't understand it were trying to explain it to others, not to mention all the SOTA models put great effort into ensuring their methodologies stay trade secrets, going as far as effectively trying to ban people from learning the math by lobbying for the outlaw of open models.

Granted, "AI" has gotten way better than it was when I took that class, but the principles are the same, with different tooling and additional filters and algorithms thrown in there, as well as letting it determine the most appropriate statistically viable path forward for a particular prompt.

There is a long history of bad naming conventions in the field of AI, including “artificial intelligence” itself imo. (What is “intelligence” here? It’s more like “automation” or “automated problem solving”.)

What really happens is that we figure out something that works, sometimes inspired by some biological thing or neuroscience thing.

Examples: neural network, attention, reasoning, hallucination, agents, experts in “mixture of experts”.

And then we go to name it, and rather than reaching for some three letter acronym we sometimes borrow a more catchy term.

I almost never means the original research was confused about what is going on. And in some cases we eventually strip away things from the original, like in neural nets which used to have a more biologically inspired activation function but we found out that ReLU works just as well because the important thing was the non linearity not the sigmoid.

The "reasoning" text that we see is what the model learned during the post training. In the post training datasets of reasoning models, "reasoning" is fed to the model with inputs and outputs. So the model learns - X is Y because the given "reasoning" text. This happens millions of times during the post training and that's how the model generalizes "reasoning". This is how the models learn anything; and the AI companies taught the models reasoning as well - they didn't have to; they could have just trained the model on input and output (X is Y); the model would have learned the exact same relationships.
