Using supervised fine-tuning (SFT) to introduce even a small amount of relevant data to the training set can often lead to strong improvements in this kind of “out of domain” model performance. But the researchers say that this kind of “patch” for various logical tasks “should not be mistaken for achieving true generalization. … Relying on SFT to fix every [out of domain] failure is an unsustainable and reactive strategy that fails to address the core issue: the model’s lack of abstract reasoning capability.”

Rather than showing the capability for generalized logical inference, these chain-of-thought models are “a sophisticated form of structured pattern matching” that “degrades significantly” when pushed even slightly outside of its training distribution, the researchers write. Further, the ability of these models to generate “fluent nonsense” creates “a false aura of dependability” that does not stand up to a careful audit.

As such, the researchers warn heavily against “equating [chain-of-thought]-style output with human thinking” especially in “high-stakes domains like medicine, finance, or legal analysis.” Current tests and benchmarks should prioritize tasks that fall outside of any training set to probe for these kinds of errors, while future models will need to move beyond “surface-level pattern recognition to exhibit deeper inferential competence,” they write.

      You don’t get it.

      In the past, the brick throwing machine was always failing its target and nowadays it is almost always hitting near its target. It depends on how good you are asking the machine to throw bricks (you need to assume some will miss and correct accordingly).

      Eventually, brick throwing machines will get so good that they will rely on gravitational forces to place the bricks perfectly and auto-build houses.

      Plus you can vibe build: let it throw some random bricks and start building around. You will be surprised of what it can achieve.

    Chain of thought is basically garbage.

    It works with coding agents because they get an automated hard failure.

    The rest of the time it’s just sampling the latent space around a response and should be trimmed out.

    That could work with diffusion models but autoregresive models it’s just polluting the context window with the hopes of finding longer tail tokens.

    The analogy I use is, it’s like a magician pulled a coin from behind a CEO’s ear, and their response was “that’s incredible! Free money! Let’s go into business together!”

    Literally no one ever claimed it had reasoning capabilities. It is a trick to produce a string of characters that your brain can make sense of. That’s all.

      Altman and similar grifters were and are absolutely making those claims but maybe we’re excusing them as obvious liars?

        They are obvious liars. Some people are just too invested to see it.

        These models only have reasoning capabilities using the most obscure definitions of “reasoning”. At best, all they’re doing are climbing to local maxima with their so-called “reasoning” on a graph as wavy as the ocean.

        I’ve mentioned this on other posts, but it’s really sad because LLMs have been wildly incredible for certain NLP operations. They are that though, not AGI or whatever snake oil Altman wants to sell this week.

    chain-of-thought models

    There are no “CoT LLMs”, a CoT means externally iterating an LLM. The strength of CoT, resides in its ability to pull up external resources at each iteration, not in dogfooding the LLM its own outputs.

    “Researchers” didn’t “find out” this now, it was known from day one.

    As for who needs to hear it… well, apparently people unable to tell apart an LLM from an AI.

      Yes, but it supports the jerk that everything called or associated with AI is bad, so it makes a popular Beehaw post.

      Not necessarily. Yes, a chain of thought can be provided externally, for example through user prompting or another source, which can even be another LLM. One of the key observations behind these models commonly referred to as reasoning is that since an external LLM can be used to provide “thoughts”, could an LLM provide those steps itself, without depending on external sources?

      To do this, it generates “thoughts” around the user’s prompt, essentially exploring the space around it and trying different options. These generated steps are added to the context window and are usually much larger that the prompt itself, which is why these models are sometimes referred to as long chain-of-thought models. Some frontends will show a summary of the long CoT, although this is normally not the raw context itself, but rather a version that is summarised and re-formatted.

      I think of chain of thought as a self-prompting model
      I suspect in the future, chain-of-thought model will run
      a smaller tuned/dedicated chain-of-thought submodel just for the chain-of-thought tokens

      The point of this is that, most users aren’t very good at
      prompting, they just don’t have the feel for it

      Personally I get worse results, way less what I wanted,
      when CoT is enabled, I’m very annoyed that now
      the “chatgpt classic” model selector just decides to use CoT
      whenever it wants, I should be the one to decide that
      and I want it off almost all of the time !!

    Admittedly, a lot of people have flawed reasoning too.

        I’ve met far too many people I wouldn’t trust to give me a reasoned response.

        Some people simply lack that capacity entirely, some just don’t care enough to spend the effort on it, while others are trying to deceive me intentionally.

          LLMs are incapable of reasoning. There is not a consciousness in there deciding and telling you things. My comment was entirely about whether LLMs can reason, not whether all people reason at the same level or might decide to trick you.

            I don’t disagree with you that LLMs don’t reason. I disagree that all Humans can or do reason.

              Well if we’re talking about all humans…

              But more seriously, it doesn’t take much looking to find someone who doesn’t reason. Just look on the TV during the next major election and you’ll find a bunch.
