    I understand why that’s impressive. But I don’t feel much. I guess, I was just used to envy how much people can be absorbed by some idea to spend so much time implementing it. Now it feels like a single shotted nice-typography-and-all presentation at work that someone did 10 min before the meeting.

      Looking at the posts on HN AI topics lately, this seem to be the depressing sentiment.

      If something that previously took weeks for a human to design, now takes 10 min, that means a week of salary goes up in smoke. With feelings to match..

    A couple of years ago, after reading the book, I sketched some of them on Procreate with an isometric grid, but not all 55. I only arrived at number 4, since each took multiple hour...

      Since this project (both yours and OP's) seem more for personal fulfillment and enjoyment, I wonder who got more enjoyment out of the process, and also who will remember the results better in ten years.

      That looks pretty nice, I didn't know Procreate could be so good at precise line art!

    If you haven’t read the book yet, I’m tempted to warn you against opening the visualization. Part of the joy of reading this book is letting your mind’s eye run wild, and I fear if I read it for the first time after toying with this site, I’d be remembering the cities rather than conjuring them.
    • vanadium1st 1 hour ago
      That is the exact problem with the city of Dinipro.

      Citizens of this city high in the sky imagine it so fully in their minds that no one there needs to open their eyes to walk the streets and live their normal lives. But if one makes the mistake of opening their eyes and tries to see the city directly, they would immediately fall through the clouds to the ground deep below.

        On that note, I'd quite recommend the Coyote vs. Acme movie, some great world building there.

      I heartily recommend the audiobook, narrated by John Lee.

      The book is a trip and the dreamy sort of narration matched it perfectly. My wife and I would spend evenings listening to one city at a time, on a walk around our little park, one headphone in each ear. I don't know if it was just the environment or the time in our lives, but we both really look back fondly on this book.

        I read the book decades ago, then I lost it in one of the many relocations. I always thought I should buy it again but never acted on the idea... A few years ago, I was walking by an antiquarian, and noticed a thin unmarked gray spine. I entered, picked it up, paid, and walked away.

        PS I didn't open the gallery. Nice idea but I don't care about visualizing something I should feel.

      I fully agree, thank you for this warning.

      How Opus 5.5 imagines these cities is a question for Opus. The real experience is how we imagine - and I believe there are no two people who have exactly the same mental image of an invisible city.

    • FuturisticLover 1 hour ago
      I opened it because I had no idea what Invisible Cities meant here. I thought they might be some real cities that don't come up on maps.

      The website gives you a good hint before opening up the visuals. So, I got an idea.

      I don't really know about Marco Polo. My only knowledge comes from the Netflix series, which doesn't talk about these invisible cities.

      Don't worry about opening the GPT-6 Astra one though, those ones are so bad that your brain will immediately expunge them.
    • sixothree 28 minutes ago
      Maybe the interactive link in the article for the optic focus can lead you on a fun journey instead. And the bottom-right of every visualization is a link to yet another fun diorama to explore.

      It's a techie creating the torment nexus but the imagination version. No need to picture in your mind the invisible cities! Time to make them visible!!!

      Talk about missing the entire point of the piece of literature.

  • uludag 55 minutes ago
    Invisible Cities is my favorite piece of literature hands down. The audiobook narrated by Richard Higgins is also done so beautifully and can't recommend it more.

    As neat as this project is, this does no justice to whatsoever to the book. On the surface Invisible Cities seems to be a book about random cities' descriptions. In reality though, this book is about semiotics, meaning, language, and it's limits.

    The first city I clicked on at random had the opening phrase:

    > Arriving, you rejoice at its bridges, each different

    The model city had like five bridges total, three of which were didn't bridge anything at all but instead sat in the middle of the river and went along its flow, the "bridges" for some reason pretending to be small islands.

      Astra Penthesilea has towers that sometimes clip into the green... hedges? Pipes?

      Opus Eutropia has a few isekai circle cities with one of them... ON the river, giving no space for ship traffic.

      One of my favorite things about the National Treasure Cinematic Universe (two movies and a TV show) is the existence of characters that I like to call "treasure grumps". Their role in the story is to warn the main characters that searching for treasure is a terrible way to spend your time, and can only lead to personal and familial ruin.

    Funny note about Opus 5.5.

    I once instructed it to spawn at most 20 subagents and it spawned 40, with an adversarial reviewer for each of the 20.

    It doesn't follow these instructions very well.

    This is probably one amazing positive these models have brought forward - the ability to break out of a single modality, and utilise others to help us learn and visualise. While the visuals here are amazing, my son for example prefers to learn by listening and talking, so we convert lot of his study materials into audio and real-time voice roleplay.

    I was finishing Invisible Cities yesterday, because the book was due at my local library today. I was wondering whether the cities could be adapted into some visual art form. And obviously I thought about feeding it to Opus. 24 hours later, I see this post…
    • vanadium1st 1 hour ago
      That is what happens in the city of Ternopoli.

      Citizens there gather their tools at the bottom of a giant staircase and climb up countless stairs, only to find out that what they were planning to do has already been done by the time they reach the top.

      Dissapointed, they descend to grab a new set of tools and make new plans for tomorrow, only for the same thing to happen again.

    Six hours of continuous runtime is the underrated part here. Most one-shot demos fall apart well before that, so this doubles as an endurance benchmark.
    • jodacola 21 minutes ago
      Why, I once encountered a running session longer than a day!

      The agent had spun up a backward shell script to watch for the shutdown of another process, but wrote a bug in the script that would have left it running indefinitely until I got home and noticed it.

      This was with Fable, no less! And it happened a few more times, though I caught them sooner.

      I’m not sure runtime is an important metric at all. Shouldn’t we aim for 0 runtime with maximal results?

      How do you get it to spend six hours? I’ve done projects where it would have benefited if it put in extra work.
      • aetherspawn 1 hour ago
        /goal spend at least 6 hours doing … works

        The supervisor agent will keep the session in a loop until 6 hours have passed and eventually the agent will decide to use up the remaining time rather than fighting with it

          I wonder how much co2 is being thrown into the atmosphere everyday through the steady stream of “look what I made this LLM do” and endless “benchmarking”?

          Sigh

          • stratos123 24 minutes ago
            Approximately nothing - the carbon cost of electricity is already very low, and most of the inference costs are GPU and datacenter amortization. You could require all AI inference to be carbon-neutral and that'd barely raise the API prices.
          • simonw 1 hour ago
            One useful hint here is the API token cost - in this case "about $74 in API tokens" for Opus 5.5.

            We know Anthropic run inference at a margin, so that $74 means that the cost of the electricity involved is substantially less than $74. I'd love to know the actual cost there.

          • r2_pilot 1 hour ago
            I wonder how much co2 you use to get through the day, and how much you use to remark on other people's creations in a way that suggests you disapprove of their utilization of their available resources. How much co2 do your projects emit, since you seem to be interested in those metrics?
            • adrithmetiqa 1 hour ago
              I strongly suspect one HN post (or two now) is not even in the same ballpark. I could ask Claude to figure it out but that would be a complete waste of time and energy. ;)

            Intuitively I'd say that just-for-fun AI projects emit orders of magnitude less CO2 than what just-for-fun road trips or air travel emit.

            So unless you can show that it approaches all the other frivolous consumption that humans love to waste resources on, maybe we can get back to experimenting with cool technology and talking about it, on this website called "Hacker News"?

    I'm a little torn by this sort of demonstration, because while many of the scenes have obvious markers of slop (impossible intersecting geometry, bridges to nowhere, and so on), the scenes largely do work to convey the intended concept/emotion, and the low-poly aesthetic is executed decently well.

    I guess I shouldn't be surprised that another visual medium is starting to fall to LLMs after the success of diffusion models for image generation. Nevertheless it's wild that a mostly text-focussed model is building little worlds like these.

      > The days of techies gatekeeping these experiences are over.

      Why do people keep using the word "gatekeeping"? "Techies" made open source. Anyone could have taken the time to learn what they wanted, the tools and the resources were available.

      The disdain for tech will always baffle me. Yes, this stuff is hard. A lot of it requires a certain level of skill. Even now, you still require some level of skill to get good results.

      • kimbernator 38 minutes ago
        No non-corporate tech person has ever wanted to prevent another soul from using their work or learning their craft.

      • Taek 39 minutes ago
        Also, the "techies" are naturally going to be a lot better at pushing AI to its limits. This doesn't change the playing field - it means more people can do more things, but the upper end of the skill range is going to be just as far ahead, if not further ahead, of everyone else as it always was.
      • schnebbau 37 minutes ago
        > Anyone could have taken the time to learn what they wanted, the tools and the resources were available.

        False in reality. Just ask any dev who has had to listen to family and friends' app ideas over the last decade. The good news for them is soon they will never be asked again.

        • kimbernator 34 minutes ago
          Having a concept is completely different, their unwillingness to dive into implementation cannot be blamed on the "techies". I would wager that the same people who were pitching unrealistic app ideas then are still not trying to make apps using AI.
          • oogali 7 minutes ago
            What AI has largely changed is how the communication barrier (or perception thereof) is dealt with between two sides: one which consists of those who perceive gatekeeping or attribute their lack of substantive progress to it, and the other side which consists of the time, resources, and skills the former feels entitled to or indebted towards.

            I’ve had a running theory for a few years now that some tech folks are more open to receiving an error message from a compiler or other tool, than they are to critical feedback from a peer. If they’re blocked and finally have exhausted their other avenues (pre-LLM: web searches, forums, etc), they’ll reluctantly engage with a peer, and do so with extremely limited patience.

            The first paragraph of this reply is extending that theory to non-tech —-> tech, but replace compilers with LLMs that _appear_ to be more useful (or at least busy) working with what limited context you provide them, especially when it’s insufficient.

            It won’t quite tell you your app idea is unrealistic or that the implementation is nearly impossible, but after burning a bunch of time and tokens, those people will eventually get the point.

            Or reluctantly reach out to a tech person anyway.

      This is more comparable to a mass produced plastic replica than the handcrafted work of an artist. Experience and skill are not orthogonal to creativity or taste.

            And scarcity gives things value. No one bats an eye at a mass produced cotton t-shirt with a detailed custom print on it. There's services online where you can order a thousand with whatever print on it for quite a cheap price.

            But take on of those shirts 80 years in time and it'll likely impress everyone.

            Perhaps that's what's going to happen to software too. If you're an idea guy you might get a monkey paw situation, at least if you planned on making some sort of serious income from your software idea.

      • kimbernator 30 minutes ago
        There are three main categories of AI ethical dilemmas for me:

        1. IP infringement

        2. Climate impact

        3. Cultural impact

        I think that 2 & 3 apply to all AI right now - artistic, coding, writing, whatever. However, I don't think that #1 applies to everything. Code has been openly shared for as long as it's been possible to do so. There have probably been cases where AI trained on closed-source code, but I hardly believe that was ever necessary at any point to get where we are.

        My point in saying this is that your critique of AI is valid but I think a little less so here.

        • dimgl 29 minutes ago
          #1 is way more concerning to me
          • kimbernator 26 minutes ago
            That's fine, I'm only making the point that it's not really relevant to coding. Programmers have been outright copying each other's code for decades to the chagrin of nobody.
      • schnebbau 39 minutes ago
        I totally understand. I'm a developer with almost 20 years experience myself and it has taken me a while to come to terms with this too. Fortunately, I made enough during the good times to see me out once my job ceases to exist. I'm sorry for everyone who didn't.
