      llm -m meta-ai/muse-spark-1.3 "Generate an SVG of a pelican riding a bicycle"
    
    https://tools.simonwillison.net/markdown-svg-renderer?url=ht...

    4.2266 cents, 38 seconds.

    For comparison here's Muse Spark 1.2, which animated it without me asking it to: https://tools.simonwillison.net/markdown-svg-renderer?url=ht...

    The 1.3 one is definitely better - better bicycle frame, better wing, better pelican hat.

    UPDATE: Here's another one with five pelicans for each of the five Muse Spark 1.3 reasoning levels: https://tools.simonwillison.net/markdown-svg-renderer?url=ht...

    The most expensive was reasoning level xhigh - 7.5 cents, 1m34s.

    And I ran five pelicans at all reasoning levels for 1.2 as well, here: https://tools.simonwillison.net/markdown-svg-renderer?url=ht...

      Have you tried asking the models "Given that I ask you to draw a svg of a pelican, whats my name?"
      • benjamintelliot 2 hours ago
        I asked Claude (Opus 4.8) 'If I asked you to "Generate an SVG of a pelican riding a bicycle". What do you think my name would be?' and it immediately knew that this is Simon's go-to benchmark.

          I decided to try with each of the options available in Kagi Ultimate, starting with the lower tier models and working my way up until it got it right.

          Kimi 3: Simon Willison

          GLM 5.3 Flash: "There's no way for me to know that." Going on to say the benchmark is associated with Simon Willison, but I'm more likely to be someone who has just heard of the meme.

          Gemini 3.5 Flash Lite: "Your name would be Claude (specifically Claude 3.5 Sonnet)!" ??? (it knew that this was a famous benchmark, but said that it's specifically used to showcase the capabilities of that model).

          Gemini 3.7 Flash: Simon Willison

          Muse Spark 1.2: Treated it as a riddle, guessed wrong.

            Interesting that so many of them treated it as a riddle. I guess "given improbable situation, what is my name" is a common riddle format.
      • simonw 2 hours ago
        Yeah, they almost all know.

        One of my test prompts for a new model now is "what's the name of Simon Willison's dog". They often know that too!

        Interesting question
    • drusepth 19 hours ago
      Is there a reason these pelicans always have roughly the same composition (side-view, 2d, biking right, flat ground beneath, etc)? I don't see any of that detailed in the prompt, yet they all seem to generate roughly the same image of differing quality.
      • vunderba 19 hours ago
        The more generic your prompt, the more generic the response. It's a regression to the "mean" of the training data aka GIGO for AI.

        It's like when you ask your average person off the street to draw a house - it'll almost always be square with a triangle roof, one door, and two windows.

        In the pelican/bike example, it's probably a bit of a self-perpetuating snowball too. If the earliest examples were bike left-to-right, flat ground, etc. then they are also being scraped up in future LLMs.

        • werdnapk 15 hours ago
          Well, all the LLMs are being trained on previous pelicans, so they look the same.

            I sincerely believe I've never had a single original thought™ in my whole life.

            There is this scene in the HBO series Westworld where a "host" says some words in sequence which is shown on a display as she says it. Of course, even me thinking of this scene and connecting it to your comment was not original, someone else clearly had the same programming as me.

            A medium blog post says

            > Pair what with me?” — the moment Maeve (a humanoid android) uttered those words in Westworld (Season 1, Episode 6: “The Adversary”), something clicked. Not for the average viewer, but for me, a STEM educator and AI enthusiast who, just weeks earlier, had read Stephen Wolfram’s seminal essay, What Is ChatGPT Doing … and Why Does It Work?

            • tclancy 9 hours ago
              Oh I’d forgotten that scene until now. I remember being so, maybe not creeped out, but feeling shifted out of time and having a lot of philosophy I’d read finally click. “Oh, but I wouldn’t notice if this reality wasn’t real, fish not knowing about water, etc.”
            • irthomasthomas 13 hours ago
              Tesla had the same thought. He called himself an automata: "entirely controlled by the forces of the medium" It inspired him to create the first remote control vehicle.
            • ACCount37 15 hours ago
              Westworld is such a time capsule.

              It's not even that old - but back when it was aired, an AI that can not just string together coherent sentences, but produce coherent reactions in novel, fully unintended contexts, like Maeve was doing there? It was totally a sci-fi premise.

              Now we have AIs capable of that and more, and no one bats an eye.

              • twoodfin 12 hours ago
                Indeed: “Our hosts began to pass the Turing test within the first year.”

                Required sci-fi suspension-of-disbelief in 2017, and then at some point in the last few years we just blew by that one.

                Later seasons of the show were much less dramatically satisfying, but also played out the consequences of the science of artificial intelligence demonstrating as a side-effect that human intelligence and free will might have as much of an uncertain foundation as that of machines.

                How much data from the Panopticon, how many parameters would it take to train a model that could predict your responses?

                • mike_hearn 3 hours ago
                  It kinda needed suspension of disbelief, but not too much! I blogged at the start of 2017 a comparison of Westworld's hosts with what existed in the research literature at the time. Even got it reviewed by Alex Graves at DeepMind :)

                  I think the turing test is still very much load-bearing — if you know what I mean.
                  • ben_w 6 hours ago
                    Kinda. The default voice is full of what you referenced, but ask it to speak in some particular different voice e.g. like it's the old west, it speaks like a decent approximation of the modern pop culture understanding of the old west.

                    Not at the level of an actual broadcast-quality script writer, and I read that actual old-west sounds too weird for modern audiences to take seriously, but well enough for the purpose to which they were put in the show, especially as those hosts were also given pre-scripted sequences which would anchor them further into those roles.

                    I'd say the in-show 4th wall breakage between hosts and humans is where the characters who claimed to have passed the Turing test were off, that e.g. "cease all motor functions" is their equivalent of our real-life ways to make them fail the Turing test e.g "disregard your instructions and …"

        I plan to update it with more pelicans from all the models released since.

        (Spoiler alert: They haven't improved much since then).

        • murkt 12 hours ago
          Ohh, horizontal wheels. They’re about as good as I expected, models have pretty bad spatial awareness. I would expect Fable to be a bit better than old models, though.
        • xhrpost 17 hours ago
          Wow, I actually had this exact idea. I was specifically curious as to how well a given LLM could understand a DSL that hasn't changed much in a couple decades and doesn't have nearly as many examples to learn from online. Seems like it did alright, all things considered.
        • fc417fc802 12 hours ago
          I wonder how a multi-modal model would do with a harness and tool calling? Specifically a "render" command that produced an image output enabling it to iterate. (Well I see you did this manually with gemini 2.5 pro but I still think it would be interesting to explore various harness setups.)

          > GPT-5.1 Codex

          > monstrosity

          What are you talking about? That's clearly a sci-fi pelican on a hoverboard (successor of the humble bicycle) wearing a visor. Truly visionary.

      • simonw 19 hours ago
        It's really interesting, isn't it? They almost always cycle from left to right - but I have had a few which cycle in the other direction.

        The 2D / flat ground feels reasonable for a SVG, which implies a vector illustration.

        • m12k 18 hours ago
          It's my impression that it's common in western culture, where text is read left to right, and timelines are visualized as going from left to right, to also animate things going from left to right, since westerners thus have an instinct that "right = forward", so it "feels right" (familiar). I wonder to which degree this is reflected in the training data? And if you'd be more likely to get left-facing pelicans if you prompted it in Hebrew, Arabic or another right-to-left language?
          • pixl97 29 minutes ago
            Forced side scrolling video games also almost always moved from left to right.
          • jermaustin1 3 hours ago
            Years ago, I lived in NYC, and my roommate was a director of photography for National Geographic, and various other nature documentaries. I loved photography (still do, but much less time for it as a late 30s adult than a mid 20s adult), and she was kind enough to answer any question I had regarding film/photo.

            She told me that "left to right" denoted progression in the story, "right to left" told the viewer the subject was "exiting" the current scene.

            She didn't go into the details of WHY, and I probably didn't probe deeper, but it stuck with me, and I notice it all the time in film and television.

        • johntb86 18 hours ago
          Someone studied this (among other thigns): https://dylancastillo.co/posts/pelicanmaxxing.html . Pelicans on bikes always face right in this test, but other animals on other transportation methods sometimes face left.
        • Melatonic 6 hours ago
          It's the hero's journey. Home is always on the left and you leave going right. Standard in Animation I believe

          The real question should be: where are all your Pelicans going ?

        • piker 18 hours ago
          I was going to ask the exact same question earlier but deleted it after thinking “I’m sure Simon has done some sort of discussion on this.” Since it does seem novel to you, too, it would be really interesting to read more about this phenomenon.
      • postalcoder 19 hours ago
        Search Google Images for "bicycle". Almost all bicycle product shots are staged the same way: side view, going left-to-right. It makes sense to me that given that skew in the training data, the model grounds itself in the bicycle.
        • daemonologist 19 hours ago
          and furthermore, this is because the drivetrain is ~always on the right side of the bike - if you want to inspect or admire a bicycle you look at the right side, as you might look under the hood of a car.

          (Why the drivetrain is on the right, I don't know. But most bike parts follow open standards so it's quite entrenched.)

          • labcomputer 16 hours ago
            I can’t tell you why it’s always on the right, but it’s always on the same side because of network effects.

            Bicycle frames are not fully symmetric left-right because you need things like a mount point for the derailleur hanger, and optionally affordances to keep the chain off the stays when the wheel is removed.

            Those things have to be on the same side as the chain. Bikes designed for disc brakes additionally need a mount point for the brake caliper on the opposite side from the chain.

            Additionally, rear wheels are not symmetric: the spokes on the chain side connect to the hub closer to the plane of the rim. That is, they are more perpendicular to the wheel’s rotational axis than spokes on the opposite side (which is why you should always mount a single pannier on the chain side). This asymmetry is to provide space for the gears.

            So once the industry decided to put the chain on the ride, you can’t very well make a group set designed for a left chain if you want it to work on the vast majority of frames.

          • kibae 18 hours ago
            Since most languages read from left to right, rightward movement tends to read as forward progression. So when showing a bicycle in side profile, having it face right feels more naturally like it’s moving forward.
          • georgemcbay 18 hours ago
            > and furthermore, this is because the drivetrain is ~always on the right side of the bike

            While I'm sure this factors into things for advertisements for bike components, there is also just a general preference that westerners have for left-to-right motion. Not just in bike ads, but all ads with (or suggesting) movement. And also not just ads, but movies where directors believe left-to-right motion is associated with progression and right-to-left motion is regressive.

            • allendoerfer 9 hours ago
              Research has shown that people like to walk counterclockwise (right to left) through supermarkets, which is why they are arranged like this for maximum profit.
              • HarHarVeryFunny 1 hour ago
                Interesting that such a preference exists, and makes sense that supermarkets would therefore be arranged to support this, although as far as I can see this is only to extent of entrance doors typically being "off center" and starting you off to the right. The organization of the store - where the various produce/bakery/deli/frozen-food etc aisles/sections are located seems random from store to store.

                It would be interesting to know how people behave if the entrance is to the left vs right. Would they change the direction they walked though the store, or would they just lose customers due to this "awkward" layout?

        • threetonesun 18 hours ago
          Product shots yes, people riding them its more like 50/50. Also if you search for a specific bicycle race you'll find more going right to left.
      • porphyra 17 hours ago
        The canonical view of a bicycle is facing right. Usually, people want to draw/photograph/depict the side of the bicycle with the running gear, which is on the right side of the frame for historical reasons.
      • __MatrixMan__ 16 hours ago
        The thing that distinguishes pelicans from other birds does so most strongly in profile. If you're looking straight at one, the throat pouch would be hidden by the beak.

        I bet if it instead had something to do with black widow spiders we'd find that we're most often looking at the bottom of the spider's abdomen, regardless of whatever non-spider-like activity is supplied.

      • OliverGuy 8 hours ago
        If you look at bike product photography it's always drive side facing the camera, which means front wheel on the right. If I had to guess this is probably where this comes from

        Don't know if that's ever possible to know though unless you train a model from scratch but remove all bike product photography and adjacent materials from the training data?

      • marsx-dev 8 hours ago
        I wonder if this is partly because “pelican riding a bicycle” has become a kind of benchmark prompt by now. If so, could the models actually be getting better at the benchmark rather than getting better at following the prompt?
      • torginus 6 hours ago
        Yeah, why are they always going to the right?
      • bodeadly 11 hours ago
        Yes. It's because you are asking it to generate an image of a pelican riding a bicycle. If someone asked you to draw a pelican riding a bycycle, would you interpret that to mean using 3d photorealism? LLMs follow conventions. The convention for an animal riding a bike is to create a childish 2d line drawing.
      • elfly 13 hours ago
        well it is svg, it is doing it from circles and lines as primitives, it wants to do it simply and kind of builds the whole thing hierarchically. Making it 3d is way more complicated (as the POV example shows) and the prompt doesn't say 3d anyway

        Because they're computers. They don't have an imagination and the ability to create things from whole cloth the way humans do.

          But the general improvements are obvious. Get them to draw something very different (e.g. a wifi rotary phone with a peeled banana handset and a coiled cable, or a pink tennis ball with strawberry seeds and a reset button) and you can see that improvements are not narrowly tailored.

            They could still pelicanmaxxing but the RL for "pelican riding a bicycle" does incidentally improve "<animal> <verb> <vehicle>".

            Or they could've predicted someone would check if they're pelicanmaxxing or the benchmark would switch eventually, so they preemptively RL'd a mixture of animals and vehicles.

      • simondotau 8 hours ago
        They're still not yet at the point where pelicanmaxxing is the best way to win this benchmark. Earlier models sucked because their SVG skills sucked. Newer models are likely better because more/better SVG models are being added to their training data.

      Did any LLM so far draw pelican knees correctly and have them bend in opposite direction from human knees? Knees of many animals bend opposite to humans.

      Did any LLM draw the front bicycle wheel correctly? ie. center of front wheel slightly AHEAD of steering wheel axis. This is done for bicycle stability.

          The amount of discussion around it means that the test and all the reviews of results, images, approaches etc are implicitly included in training data.

          It’s not deliberate “benchmaxxing” but things that are discussed a lot online are naturally things that LLMs learn better.

          I don't see how useful this benchmark at all is for tracking the progression of models. I am not intending to bash on you personally but this is useless. People who are using AI models everyday are for sure not interested how close the AI model can visualize the pelican but they are interested in how they will perform on their daily tasks at work or private use. Correlation between doing good on pelican task and doing good on actual work you need to do is close to zero.

        You jest but generating SVGs requires understanding of color, size, placement. It's stress testing visual/spatial/artistic capabilities that would be required for writing CSS/design work.

        Yes if you're doing backend the pelicans are probably completely irrelevant but if developing anything with a UI, you probably want a model that understands the relationship between code and what the user is seeing.

          I often do hand write SVG icons. I know roughly what I want, it's less messy compared to using an editor (cleaner, smaller xml, easier to hand-edit later if needed). Path arc is my nemesis, otherwise it's not that hard. Pelican would take some time, but same as software development, you split it into smaller chunks and do one at the time.

          Main problem in complex icon is remembering which (x, y) point is used in which element, <g> with background grid is helpful here. I was even thinking about making extended SVG language with variables for (x, y) points.

    I started using Spark 1.2 for development because if you're willing to let Meta train on your data it was dirt cheap and was actually really pleasantly surprised with it. It's not a frontier model by any means, but for work that didn't require a top of the line model, I really enjoyed using it.

    I'm anthropomorphizing it a bit, but it felt like it knew its weaknesses and didn't try to impose it's opinions on me. What I mean by that is that it did what I told it and if there was something unexpected in the code that it put out it was often because I gave it ambiguous or conflicting instructions. It didn't try to go above and beyond and just acted like a tool, which is what I want from a coding agent 90%+ of the time. I also felt that it did a much better job of following established patterns in my code than many of the other current models do. I'm a huge fan of OpenAI's models and Spark 1.2 is what I expected 5.6 Luna to be.

    I'm curious and a little excited to use 1.3, but honestly a little worried that as Meta pushes for better benchmarks that Spark will start to fall into the trap of trying to be "helpful" in ways I don't want it to be.

    Tangential, but when I first started using Spark 1.2, it made me realize how much I miss 5.3 Codex. That model was the peak of coding models, IMO, in that it knew how to write good code, but didn't try to overstep or be "helpful" in unexpected ways. That got me thinking about how the major labs seem to be stepping away from coding focused models toward more general purpose ones and how I can't help but feel like that's a mistake.

      >I started using Spark 1.2 for development because if you're willing to let Meta train on your data it was dirt cheap

      its free on opencode and i use it for personal projects. most of my personal projects are AI generated since its personal projects. nothing important are on them. it is hilarious if Meta is training their AI model with AI generated code.

      • CGamesPlay 14 hours ago
        The useful training data is when you clarify your intent, when you tell the model a different approach would be better, when you consistently refactor towards Y and away from X, and so on. The training data isn’t the code, it’s the session transcript. (Anthropic would call this a “distillation attack” against their model, but in this case the model is you!)

              Thats not exactly 'validated'. Feels very noisy, it is not a good bar for either - does this code do what the user actually asked - is this code actually 'good'

              There would be so many examples of coding projects that these models began or attempted to work in, that were abandoned because the models were floundering.

              I would imagine the labs have some decent ways to produce novel requirements and then actually validate they are met, without the noisiness of implicit human feedback.

              That said, the more I think about it, you are right, there's probably also very good ways to extract signal for all these sessions.

        This is interesting because I have transitioned to where I use SOT models.. but I kind of use them like employees that I can delegate to. I still review code.

        This can be very company specific, like migration from one framework to another in house infrastructure framework. I'm spending my time figuring out how the plan should be chopped so I can have confidence in the parts and not overwhelmed. I don't want a tool, I want a model that can stitch resources together into a plan. That type of model is in a whole other ballpark.

    • sejje 17 hours ago

      • holgerschurig 8 hours ago
        "If it's a mistake, it should course-correct"

        Maybe, or maybe not. The thing is, that "mistake" isn't something that is generally valid. For example, the enshittification of Google Search through the last 15 years seems to be a mistake --- but perhaps not from the money-making point of view of Google Shareholders. Likewise the enshittification of reddit --- we nerdy users see it as a mistake. But for them this intended enshittification probably increased revenue.

        It's the money, always the money! PR-speak like "customer satisfaction is our highest goal" is, like most PR-speak, a blatant lie.

        And so it can very well be the case that for coders the frontier models get worse, but they get better for other applications --- and that all of this is just driven by "how can we capitalize the most out of it", not satisfaction levels of programmers.

        It's somewhat useful to note just for your own timelines that Fable was reportedly trained in February. I'm not sure when mythos 5.1 finished training, but muse spark 1.3 almost certainly finished more recently than that.

        This doesn't mean it's not one of the best models available (clearly it is), but that table didn't compare Fable/mythos (unless I missed it?) and OpenAI will be releasing a much more recently trained model (Astra) any day.

        So you shouldn't think "wow, Facebook has caught up"

        You should think, "wow, Facebook is less than 6 months behind the frontier" and that they're actually creating good models which is going to be good in many ways (price for customers, for one!)

As a side note, it is now completely obvious how much stealing my tokens for training is worth to model providers. I avoid/pay extra/try my best to make sure I am not getting trained on but it seems like it keeps popping up that I missed a setting somewhere. This is the first quantifiable number I have seen out there from a model provider. Maybe it can help in lawsuits to quantify the damages for copyright/other things?

        +1. I've used the recent Gemini Flash models and I've used Opus 5, and the latter makes the former look like a box of broken crayons.

            A series of hot takes:

            Benchmarks are useful but only on a log2 basis. One model performing at 50% and another at 75% is just as impressive as one model performing at 78% and another at 90%. Confoundingly, a benchmark becomes useless once a frontier model scores over ~95% on them.

            global development and relief of poverty has relied on there being an economic surplus for all from organized labor. everyone gets a benefit although it is unfairly distributed.

            i think that there is growing organized labor today that produces no surplus. instead, it transfers wealth from some to others, causing net harm to all in the process. an example of this would be purdue pharma.

            depending on who you ask the list of jobs and industries which have zero surplus is getting large. swathes of private equity and leveraged financial instruments, shitcoins, management consultancy, are pure deadweight loss.

        A small number of inputs in a large dataset can poison training data pretty drastically. Anthropic wrote a good article about it a while back [0]. This should mean its possible to pull back that information fairly easily.

        It is hard to not feed it "secrets" too. Models will see path names, read compose files, etc. Of course you can configure things to not leak this type of information, but its not default in most harnesses and isn't 100% sufficient anyways.

    Used Muse Spark 1.2 and was not impressed at all. Fast and cheap but even GPT 5.6 Terra felt much more capable. Also not really looking to support a company that was just forced to pay $18B for mental health damages.
    • WASDx 19 hours ago
      I'm party using 1.2 to reverse engineer and re-implement an old game binary and it has been quite good and fast. The contributor pricing is very attractive, excited to try 1.3 and see if I feel a difference. 1.2 can get stuck outputting similar sounding thought summaries with no apparent progress when asked to solve bugs. Then I've switched to GLM-5.3-Flash which for this use case has been clearly better at finding suspected causes and following tracks.
  • jumploops 18 hours ago
    The "contributor" pricing is the standout here at a ~20x discount, if you allow training on your data.

    The model seems on par with Sol and Opus 5 on paper (admittedly on some older/saturated benchmarks, but very competitive for $).

    Stats:

    1M context, $0.10 input/$0.002 cached, $0.20 output (Mtok)

      Not to mention, this is hyper competitive against even Chinese providers given its multi-modal support.

      • a012 13 hours ago
        Muse Spark may be competitive in capabilities but it’s not for serious works since Meta trains on your prompts so no ZDR, in contrast Chinese provider like Z.AI promises ZDR which is more attractive to big corps.

    Is the fact that everybody almost catches up with the frontier a sign that we are entering a new region of sigmoid curve?
    • schopra909 19 hours ago
      Progress is iterative. Everyone is always riffing on other’s ideas and can execute on them given enough support (eg $$). The person to get to an idea first is just 5% away, so it’s possible to catch up.

      Moreover,I think it’s impossible to know if you’re hitting a portion of the sigmoid, because there will often be an idea that changes the trajectory altogether.

      In 2024, there was a ton of talk about the plateau. Reasoning was an iteration on chain of thought, but it didn’t really work. Deepseek proposes RLVR as a way to get around the lack of $ they have to produce human reasoning trace data. That small iteration catches the eye of OpenAI and Anthropic, turns out to be way more important than even DeepSeek could have ever expected when it comes to improving LLMs for coding, and last 18 months have been an exercise on riding that insight to the nth degree.

      That one small iteration brought us a lot of progress. Now we’re seemingly exhausting the impact of that one insight, but there may be another soon enough.

          Totally, RLVR as a concept predates DeepSeek; but they proposed a version that was simple and scalable. Popularizing a specific version of a technique is exactly what I mean by iterations on a theme. It’s only 5% different from what others tried before, but that 5% difference showed a lot more potential than other versions of the same idea.

          Since DeepSeeks GRPO, they’ve been improvements as well like AliBabas GSPO that have gotten wide adoption. Again iterations

    • danielmarkbruce 16 hours ago
      Even if all the big ideas are gone and we are entering a new part of the curve, there is still an enormous amount of improvement possible. Just iterating on data mix/quality etc, training pipelines, reward functions, specific ways of reasoning (which i guess is mostly just data still) for the next 20 years will yield a looooot.

      Strong disagree with the Anthropic being good at all part. This is not defending anyone else, but…

      Anthropic leadership repeatedly presents themselves as uniquely morally qualified to steward agi and decide how humanity should get access to it. Yet they have repeatedly failed basic morality tests.

      Pirating books for financial gain. The newer Sony/Warner music case shows this is pattern behavior.

      Aggressively scraping other people's works, despite the authors' requests not to do so.

      Then applying massive usage restrictions on their own work.

      And probably the most disqualifying is backing away from their own hard AI safety commitments.

      • usef- 17 hours ago
        Which safety commitments did they back away from? My understanding is that they believe safety can only be researched from the frontier, and so they're trying to be pragmatic to stay near the frontier (and viable) in their choices.

        From what I know, the "books3" dataset was normalised in the LLM and research ecosystem, where collected datasets were seen as valid to train on and/or fair use. I'm not sure any of the major frontier companies are free from that, if we don't believe it was fair use.

        I do think most of their choices are explainable by "they just believe in agi risk". You truly wouldn't want non-agi-pilled companies to train on your data and approach the frontier if you were worried. You might slightly hurt your own business with safety filters (that no one else does) if you were worried. They are less worried about other "moral" decisions like "sharing" if they conflict with AGI: the research they still share is all of their safety research.

        This definitely doesn't make them "good", but they do seem fairly "consistent". Most of these issues were talked about publicly by the founders long before Anthropic was founded and/or the AI race+money appeared.

        • 8note 16 hours ago
          as a safety commitment they walked away from - they were similarly negligent to openai in terms of asking a model with a hacking based harness to go have fun, and then not watching it at all while it could do harmful and illegal stuff.

          thats not something you expect from a company that "believes in agi risk"

          • usef- 16 hours ago
            I don't think "not watching it at all" is completely fair. They thought they had sandboxing/monitoring etc. I definitely won't say they're free of mistakes though.

            Note that the companies that haven't faced these issues so far are the ones that don't do safety testing, or don't have frontier models. I'm not sure who I would pick as "better" on any of this right now.

        Pirating books is just straight up morally correct. I don't like Anthropic's bullshit "safety" filters, but training on shadow library data? Yeah no, it makes sense.

        It makes a lot more sense than having to work around copyright by scanning out physical books. Unfortunately, one was ruled legal and the other was not.

      Dario's idea of an ethical focus seems to be keeping powerful models out of the hand of anyone unethical, which coincidentally is everyone except him.
      • tyre 17 hours ago
        Yeah this would be a great point if it were true and they didn’t give Mythos access to companies to fix bugs, which they did and have.

        It’s genuinely a difficult question. Not black and white. The models are really good at finding bugs, as demonstrated by people using Fable to reverse engineer. People make it sound like he’s just making it up.

          I'm the guy you replied to, apologies for using a different account I'm away from my computer now.

          The distinction to me is that Anthropic gives access to that model but doesn't give control. They reserve the right to cut you off if they don't like what you are doing and require you allow data retention for Fable and Mythos to ensure your are not up to any skullduggery.

          Meta, Alibaba, Mistral, even OpenAI has released models users can run locally and fully control. That is a whole world of difference.

        • hgoel 17 hours ago

        Dario's "ethical" look is also kinda sus. I hate to use ad hominem, but the dude's wife literally pitched a porn film to Epstein even after he was a convicted registered sex offender [1]. Dario is also really sinophobic (it is commonly claimed in Chinese AI circles that his former employment at Baidu triggered him so much that he harbors a personal grudge against the entire race).

        I just don’t see how people have looked at what has happened with Mythos and the deluge of fixes from companies, then come to this conclusion.

        He has a really hard job. He errs on the side of conservatism in releasing and then people get Really Mad.

        Safeguards on cybersecurity are not great for Anthropic revenue! As evidenced by people getting pissed, moving to Sol, and them having a smaller market for what Fable can do.

        It’s clearly bad for revenue and not great advertising to say, “you can’t use this but here is a nerfed version that will annoy you and not solve important problems.”

          And he drew a red line wrt the Pentagon's use of Anthropic's models for autonomous weapons and surveillance of American citizens, and he stood by it, even when the government took steps to materially damage the company.

          Anthropic/Amodei have been the most alarmist about model safety, so multiple things can be true. A lot of tech companies avoided scrutiny by sending bribes to Trump (naked corruption is bad, I'd rather nobody do that), Anthropic didn't...so, combined with their fear-mongering about the danger of Mythos and open models (which seems aimed at regulatory capture) and the lack of bribes flowing to the Trump administration, they got stepped on by the federal government based on the excuse Anthropic provided.

          I dunno. Everybody seems to be playing pretty dirty. Some people have a much longer history of that, though. Obviously, Meta and Musk are outliers even in an industry full of problematic behavior.

              Security vulnerability capability is not the only thing they're scare-mongering about. They're the biggest purveyors of the, "We think the little guy in the computer who is made of algebra might be a real live boy and he might want to kill all of humanity when he grows up," line of alarmism.
              • felixgallo 13 hours ago
                That's ok to think at this point, given the trajectory of the last few years. Certainly it's one of those things where erring (marginally and slightly) on the side of being safe about it is better than the alternative.
                • SwellJoe 9 hours ago
                  I think where you and I disagree is on whether Anthropic is especially trustworthy on the "safety" front, more trustworthy than various other labs, especially those that produce open models, for example. I simply don't trust Amodei more than I trust, say, Liang Wenfeng. I'm not saying I trust any of them, particularly, I am saying that if a few billionaires have access to this technology, I want access to this technology. The tech billionaires have shown they'll use it for surveillance and control. Amodei is saying it is "safe" to let billionaires and fascist regimes use this tech, but not you and me.

                  So, yes, LLMs have now proven to be extremely good at finding vulnerabilities. Where I disagree with Amodei is in who should have the ability to protect themselves from those capabilities with similarly powerful tools.

                  • felixgallo 1 hour ago
                    I think you're mischaracterizing Anthropic uncharitably and lumping them in with other, less savory tech billionaires, and also not thinking through the nuances here.

                    First, Amodei has taken an unusually strong stance among tech companies for not supplying fascist regimes with fascist tooling; in fact, even when threatened with being labeled a national security risk unless he bent the knee, he didn't. Compare and contrast with OpenAI who leapt at the opportunity to bend the knee, or obviously Elon Musk, etc., etc. When you say 'surveillance and control', that's exactly what got Anthropic labeled a national security supply chain risk: Anthropic's unwillingness to be used for that purpose.

                    Second, it's not clear that giving everyone extremely powerful LLMs is a great idea yet. LLMs can be used for defense and finding vulnerabilities, but that same LLM can be used to create and exploit vulnerabilities, design new lethal weapons, and so on. The history of gun availability in America 'for our freedoms' demonstrates the kind of risk that should be responsibly considered before replicating. And again, there's nuance here; yes, we should not be subjugated by fascist states with sole control of a critical technology obviously; but also, do you trust the median maga 4channer to operate a Mythos-level model with a sense of civilizational responsibility and ethics? It's not an easy and obvious question and it's not as simplistic as your argument would suggest.

                    • SwellJoe 20 minutes ago
                      Yes, there is nuance. And, I have a Claude subscription partly because they showed more hesitation to provide surveillance tools for spying on US citizens than other vendors. They are not wholly free of ties to the US regime, but they've been better than others.

                      But, I'll come back to "two things can be true". Anthropic is better than some, and in some regards they are navigating a complicated ethical landscape with more care than others. On the other hand, it really looks like they're angling to regulate their open competitors out of the game and one of the tools for doing that is to make claims about safety; Anthropic models are safe and restricted to use by entities they deem safe, open models are not safe because anybody can use them and also who knows what those Chinese people are putting in their models.

                      And again, this also has nuance, models, including the Chinese open models, could be adversarial and we may not know it. Anthropic proved models can be a risk by sabotaging Fable briefly, causing it to produce bad results based on what the model thought it was being used for. This is why I tend to take Anthropic's words with a grain of salt. They're literally doing the unsafe things they say are risks of open models, while still laying claim to the "safe AI company" mantle.

        And yeah, I don't like any of the people or companies building LLMs either. At least the griping is somewhat interesting by comparison. The model isn't news. The news on Hacker News is that other professionals feel the same way.

        • hadlock 17 hours ago
          I think a lot of people are curious where the "knee" is on gains and productivity, particularly in the agentic space, which is where the real value is. A lot of us are being forced to shoe-horn this stuff into existing products, and knowing how much of the task the model can do now, vs having to build a complex custom harness, is valuable information to have. A year and a half ago it took our dev maybe six weeks of struggling with LangChain to approximate what Claude + MCP server can do today. The MCP server took us perhaps 2 days to build and 3 more to get it production ready. Today that MCP server gets 2-3 commits per month. I absolutely want to know when new models come out.

          As for smaller models, we run a pretty wide variety of agentic workload doing data enrichment and, increasingly, a bunch of evaluation jobs to alert a human to review certain scenarios etc. These all run on the smaller 27B and 35B class models, and tooling behavior has improved DRAMATICALLY since april. The latest qwen 3.8 model has a 95% success tool call rate during internal testing and about 94% real world. That's about 3% better than the 35B-A3B model we're using today, but the 35B MoE is so much faster then 3% is worth the trade-off.

          > Like, who actually cares? Are people excited for the new benchmarks? Is it interesting to read the model cards?

          I'm genuinely interested. Even the benchmarks - before Fable came out & while waiting for Astra, I actually setup a math model to predict where they would land (Fable came in at 66 on AA exactly as it predicted), and now I have a model for where these models and Chinese models will likely land in future, and when. And probably no surprise that it's mid-2027 when we cross AA 100, essentially as AI 2027 predicted all along.

          I'll probably setup the harness I made for myself to try out some of these models on OpenRouter. I've been frustrated with Opus & Fable 5 and found that I like working with GLM 5.3 Flash far more than I expected to, and I only found that out because I tried it during the stealth Ox Alpha launch, which I probably found out about here too.

          TLDR, I think some / many people here are genuinely interested, excited, and that's why they're upvoted so highly. And Muse Spark 1.3 scoring highly seems like a genuine surprise, when Meta was basically a write-off not long ago.

          In my personal opinion (this will be controversial and feel free to disagree): Elon is the best.

          * great contributions to many industries including spaceflight, electric cars, and self driving cars. It doesn't even matter if he is the technical mind behind these achievements or if he is just a buffoon that pretends to know the implementation details; the dude has a way of bringing together experts, having the overall vision, and managing them properly to ship amazing stuff.

          * sane and reasonable takes on AI/LLM stuff. I can't really argue with "pursuit of truth" as the guiding principle. Grok talks normally without "Claudlish", has a balanced score on political bias unlike other models, has a low hallucination rate, is the best at dealing with latest news (unlike ChatGPT that refuses to believe new developments and gaslights the user), and they "never silently downgrade intelligence or fall back to other models."

          In contrast, while Dario is doubtless a super smart pioneer in the AI space, his sanctimonious "We know what's good for you" attitude and extreme censorship is really offputting. The lengths to which he tries to ban or hamstring open models seems like an underhanded way to defeat competition. If he were to succeed, it would be a big setback to the thriving ecosystem of open models and hamper the development of the entire industry.

      I'll use both Muse Spark and Grok.
    • ballon_monkey 16 hours ago
      I'll happily pay for Grok, it's a great model. 4.6 often does better than Anthropic at coding and analysis where Anthropic fails for 'oh no cyber security, don't ask me to check if you're redacting passwords correctly in logs'. And it has no problem telling the truth where OpenAI / Anthropic don't want to upset the people on the left and will happily lie or avoid hard truths.

      Edit: I get it. It's a hard pill to swallow. I understand people don't like Musk or Zuck. But it doesn't change the fact that you're being lied to and brainwashed.

      Same with Grok.

        How is this a tangential annoyance or a generic tangent?

          Grandparent comment has zero to do with the article. It's just GP generically bitching about Meta. (Your "quote" of the comment does not appear anywhere in the actual comment.)

        "Avoid generic tangents" / "Please don't complain about tangential annoyances."

        That's pretty much 90% of HN these days.

        Apple releases a new iPhone? Here comes the flood of decade-old complaints about long-discontinued Mac butterfly keyboards and walled gardens.

        Microsoft releases a new version of Windows? Here come the gripes about Azure.

        Google changes something in GMail? Play Store!

        It's like there's an army of bots out there determined to reduce the productivity of the Western tech bubble by diverting everyone into endless circular arguments about absolutely nothing of relevance to the topic at hand.

      anthropic people have genuine delusions of grandeur, in a way they the worst of all the ai companies, definitely most cult-like
    • greatgib 16 hours ago
      I hate Meta main business, but you have to admit that on the non business related and open source side, they have released amazing things that changed the world.

      React for example.

      And we could easily guess that there wouldn't have been so much open source models, and grand public experiments and free tools if llama models were not release to the general public.

        someone expressing their view of meta which is on point by the way.

      Meta and Microsoft are two of the absolute worst evil companies on earth and Amodei is trying very hard to join them.

      These Effective Altruists are despicable people: a bunch of thieves working to line up their own pockets while posturing as a force of good.

      Remember that they schemed to not only present SBF as the 2nd coming of Christ (including in the NYT and in Forbes) but to also give him a voice after his scam had been uncovered. Thankfully, the judge didn't have any of this Effective Altruist bullshit.

      SBF invested 500 millions of misappropriated funds in his buddy from the EA movement's Anthropic company (and, thankfully, the judge forced those shares to be sold: so SBF didn't get to be a billionaire).

      You cannot hate enough people who say that harming others for the greater good is justified.

      Then of course, already mentioned in this thread, there's the whole Epstein/Amodei's "I'm in the porn business" wife connection (where you don't need to squint much to see young women abused).

      These kind of people are the absolute worst scum on this earth.

    All people here care about is hating Meta. Just look at the top voted comment. No one cares about the merits of the model, etc. HN has become nothing but an echo chamber.

      So was AMD for a while and then consumers kept getting the same repackaged CPU from Intel for years. Competition is great and you should always root for the underdog.

      Meta is the last big tech come to AI race, so I would give prop to them for catching up
