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.
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.
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.
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.
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.
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.
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.
I've randomly chosen Phyllis. It says, the city of bridges, but bridges in the demo are just built in the river. If you really look at the bridges, that doesn't make any sense.
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.
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.
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.
both the linked camera lens example as well as the last one the author linked runs at ~5fps on vivaldi and pegs CPU 100%. i have never seen any 3d visualization website have performance this bad, i assume they're not using webgl given my GPU is 0% utilization.
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…
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.
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?
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”?
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.
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.
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?
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"?
It reminds me of Total War. The soundtrack and way that the map is shown. Is Total War an inspiration? Anyways, I liked the visualization. But I never read the book, so I followed (partly) droidjj recommendation
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.
$74 vs $ 10 vs $25 for the same prompt,
The interesting number is not actually quality, its what we can get per dollar like 6 subagents runs in parallel.

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

On that note, I'd quite recommend the Coyote vs. Acme movie, some great world building there.
Don't worry about opening the GPT-6 Astra one though, those ones are so bad that your brain will immediately expunge them.
I fully agree, thank you for this warning.

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.
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.

You made the mistake of looking too closely
like bridge over slop and water, i will let you down.
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.
Slop has never been this beautiful before!
Not to mention that the slop site claims that the cities are Invisible, when I can clearly see them.
I can't imagine a worse thing happening to a better book.
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.
20 sub agents, 20 doms.

Does this bring any happiness? for me, No. effort need a purpose.
Well it still has the trademark "colored left-side of the boxes" ai slop, but otherwise looks (and sounds!) very impressive.

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.

Most of that time may have been spent on testing.
How do you get it to spend six hours? I’ve done projects where it would have benefited if it put in extra work.
/goal spend at least 6 hours doing … works

USE carbon dioxide to get through the day? What?! We're not plants!
This has given me a great idea: I have a modest proposal on how to reduce net CO2 emissions while not reducing token consumption at all
> I wonder how much co2 you use to get through the day
What a terrible thing to say to human! Being (presumably) human, it is their inalienable, natural-born right to do so.
Shame on you.

On the down side, $84 spent on a slot machine might have actually yielded some benefits.
I ran cat /dev/urandom for six hours but I didn't need to write a blog post about it

The creation really is amazing. I harnet heard of the book but got a long way through it!
What a beautiful website, wow. I've been online 10,000s of hours, have seen pretty much everything and this one goes straight in my Top 10.
I'm so glad I'm able to witness this Cambrian explosion of software :).
