    I use LLMs for some things that are outside the more common use-cases (in my case 3D design for 3D printing) and one thing I've noticed is that the errors it makes are so completely unlike human errors that they are hard to anticipate.

    It will do things like build perfect snap catches but put them so the the pieces they are connecting are rotated 90 degrees from how they should be. It's "dumb" error, but hard to say the model itself if dumb because it does other very hard things so perfectly.

    This sounds a lot more like Opus 5.0 than Opus 5.5 TBH. I wonder if that was an earlier investigation because 5.5 has improved that kind of language a lot.

      AI capabilities are "spiky": they extend far in some dimensions but fall short in others, seemingly at random. See for example the recent "thus spoke compute" musical[1]. It's an absolute banger, the graphics are impressive, and so is the writing. But some of the metaphors make no sense, the text highlights are in the wrong places, and the train animation at 2:35 is running backwards!

      A person capable of making the rest of the video would never make those mistakes, but an AI does. Perhaps our intelligence is also spiky, and we're just used to the general shape and variance within humans.

        One might say a calculator is just another example of "spiky intelligence", merely spikier.
        • famouswaffles 1 hour ago
          No, one might not say that. Calculators are not regarded as even a Narrow Intelligence because there's no intelligence. And no, not because of the 'humans so special' or 'it's software!' tautology that oft gets repeated in these discussions. I mean there's no adaptability whatsoever. A Chess bot has it (in its narrow domain of Chess). A calculator does not.

            So what's the difference between "no adaptability" and "being very spiky"?

            Thermostats are smarter than calculators :thinking_face:

          How often does the calculator get something wrong?

      This analogy may be too close to the real thing to work, but it reminds me of a Chinese room type situation where its entire understanding of the world is through messages of text.

      You say that’s an error a human couldn’t do, but imagine if the human has never seen or touched the kind of item you were making and relied entirely on text descriptions to build its ontology. Off by 90 seems like such a believable mistake.

        Also, not to sound like a naive hypemonger, but: in a decade I'd bet a ton of money the best AI systems will make strange mistakes of this nature at a far, far lower rate than they do today. They will gain a more holistic and more human-like perspective about each task.

        (even if it's through some silly means like explicitly talking to themselves like "if I were a human doing this, what [... 5 million tokens in 2 seconds ...]" but also of course if they crack ASI and get something more efficient and intelligent than a human brain by then)

          I think of it kind of like how Chess AI make "mistakes" which are unrecognizable to humans but a stronger AI would be able to pick them apart. That's kind of scary...

      Unfortunately, there are reports that they have “dumbed” down Opus 5.5 already.
      • sampullman 29 minutes ago
        Which reports? There are lots of people watching model quality now, so it seems like there would be clear evidence if it happened already.

      It's "dumb" error, but hard to say the model itself if dumb because it does other very hard things so perfectly.

      Maybe the model isn't intelligence in any form, except perhaps as an imperfect reflection of the intelligence of its training data.

      • Isamu 4 hours ago
        I agree, there’s the collective intelligence that created all the content used to train the model. The model is a superposition of all that material with RL tuning. Analogously to reading a book, the intelligence you perceive is from the book’s creator.
        • NewJazz 3 hours ago
          What about DNA? There are things we do that we never read in a book, maybe never seen someone else do them vefore, but we still do them. Or we still feel a certain way. That doesn't come from "human training data", unless you count the DNA as training data.
          • exe34 5 minutes ago
            Palaeolithic natural selection did the training.

      In general llms are weak with spatial reasoning. This seems to be an unsolved problem. Probably because human language is generally imprecise spatially and humans think about spatial problems in visual terms. I wonder if having an llm make a 3d design in a format an image model could check would result in a better outcome?

        Having used them heavily for 3D model understanding since February I can say it's nuanced.

        Opus 4.6 and 4.7 were bad, but GPT 5.2 and above were very usable. Opus 4.8 was usable, but the GPT 5.x series was better.

        Fable is great.

        Opus 5.0 was interesting. It could solve some problems that Sol 5.x couldn't solve (applying a G2 curve on a 3 way corner where one face was a Bezier curve) but you had to be super prescriptive ("only answer the question"/"only do what I tell you and stop when done") or it would go on a hugely involved validation journey that didn't really achieve a lot.

        Opus 5.5 is better than that was in that respect.

        Sol 6.x is great, and my daily driver for this (I use Opus for coding though)

        Astra can solve problems that Sol can't but for some reason on easy stuff makes uglier solutions.

        For all models it's very interactive though - we aren't at the "agentic design" phase for most things yet.

        Here's a sample of what I've been able to get them to design with me: https://x.com/nlothian/status/2099023496794018067

        I think that this is an unsolved problem in the same way that mangled fingers in image generation was an unsolved problem.

        Through at least Opus 4, LLMs were practically useless for authoring any sort of coherent procedural closed-curve geometry (I know this with strong confidence because of the little animated guys at https://letterspractice.com).

        Opus 5.5 can bang it all out. Possibly a deliberate RL sort of thing or maybe another surprise emergent capability.

      • Aerroon 4 hours ago
        Is it that LLMs are weak with spatial reasoning (and memory) or is it that we are unusually good at it?

        When I need to use a program I seldomly use I'm far more likely to remember where I need to click to open it than the word I need to search for to open it.

        • kfarr 2 hours ago
          Yes I like to think of humans with built-in accelerators for certain tasks -- our visual and spatial reasoning is off the charts presumably because it's a life or death skill!

    Good read! How many pages of text were in scope? I'm not sure if the 1615+1629 pages were the total or just a subagent.

    If they were the total I would say it was arguably more impressive the author was able to narrow it down to just 3000 pages than it was to find the dodo mention amongst those!

    • mkl 4 hours ago
      Those are years, not page counts, right? The article mentions "millions of records", but I'm not sure how big a record can be.

    My dad died and had many many notebooks of his journals with very hard-to-read handwriting. Is it worth the effort to scan all of these so I can feed them in and go to work. Seems like so much minutia is out there, ready to be meta-understood.
    • komali2 3 hours ago
      I set up an OCR flow using local models on all my many tens of journals stretching back the last 30 years.

      I would say it's about 80% accurate, which means it's missing enough key words to make a lot of it uselessly unintelligible. I can easily compare the images against text I turn up in a grep which is nice if I'm looking for something.

      Allegedly Claude set up a system for retraining for my handwriting, but it would require me to manually revise several hundred pages by hand so I don't think I'll ever do it.

    What a great read, I generally associate substack with verbose, low quality content, but definitely not the case here!
