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...

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.

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.

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.

I copied the prompt from the article and inserted it into Claude, here is what it created:

(the standalone version at the very end of the chat is the one that runs in the browser)

Well, overall, by faaaaar not that beautiful as what the author from the article received? :-D

(though, it was done with Opus 4.8)

    Kublai Khan received an ornate letter signed by Marco Polo: "In Madrid, City of Lost
    Things, no item remains where it was set. If one drops his key in the dirt, he may
    never re-enter his home, and, even if he manages to stoop and recover the key, he may
    rise to find a tulip garden where his house once stood. In complementary fashion,
    things lost by others are forever turning up: A pocket watch on a coffee table. A fond
    memory in your recollection. I even know of a prince who turned up in a prison cell.
    When he appealed to the guards for his release, he failed to find the crown on his
    head, and when he was asked his name, he searched his thoughts, but could not find it.
    Indeed, the only hope now for the release of this prince of Spain is for you to send
    back 300 ducats for his release. Of course, he will reward you handsomely once he is
    out. Yours truly, Marco." Kublai Khan cocked an eyebrow and declared before his court,
    "Hey, everyone: Looks like we're about to get ripped off by the guy who traded gold
    for paper!" The court erupted in booming laughter.
                              — Italo Calvino, Invisible Cities 2: This Time It's Visible.

Such a drag- a few carelessly lumped together Ai demos. I mean the headline says it all, there is not much more to it. ok, no thanks!

wsowens • today at 3:54 PM

Like many other people in this thread, I feel like passing what would essentially be a hobby project off to Claude robs the creator of most the fulfillment and gives the viewer less reason to appreciate it. But with the models being as good as they are today, I genuinely feel conflicted. If your end goal is to share something with others, why spend a weekend on a project like this when you could just hand it off to Claude?

Yeah. This fails to load both in Opera and in Chrome on Android. I'd tone the hyperbole down a bit.

andrew-v • today at 12:33 PM

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…

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.

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.

Very cool, thanks for posting!

And shame on all the people shitting on it because AI made it. If you valued art for art's sake, you wouldn't be so bothered when somebody makes something art-adjacent using some technique you don't approve of. It in no way detracts from the kind of art you admire. Don't be type who just has to let others know that you find something they like to be beneath you.

korzinka • today at 2:22 PM

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.

Garlef • today at 4:30 PM

It's one of my favorite books - and I think it deserves better; it's a conceptually very dense text and just slapping together a few 3D models misses the point

it's also not very astonishing that the current models are able to create this - it looks exactly as expected

and I actually think getting an interesting AI generated rendition of the text from a single prompt is a worthwhile endeavor

maybe even a good replacement for the pelicans: it would test if a model can engage with a text beyond the surface level

but this ain't it

sreekanth850 • today at 1:24 PM

Does this bring any happiness? for me, No. effort need a purpose.

armcat • today at 1:47 PM

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.

While reading the book years ago, I did not visualize Isidora as a city with 9 houses, like a children’s book, or a little video game level intro, but so unlike Kublai Khan or Italo Calvino.

dhruv_kernlai • today at 12:39 PM

$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.

keyle • today at 2:09 PM

On the down side, $84 spent on a slot machine might have actually yielded some benefits.

sitzkrieg • today at 1:46 PM

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.

Latent space is amazing isn’t it

narfman0 • today at 2:38 PM

wow that's awesome! super cool :), fyi so inspiring that I did something similar for d&d forgotten realms, including a timeline: https://narfman0.github.io/realms-atlas/ fable drove it, opus agents did the work, took 30-45 minutes. (intend on extending to planescape, elaborating on significant historical events, and some text to speech narrating cool events)

rock on

tuesdaynight • today at 1:27 PM

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 just have zero interest in looking at any of these "AI did a thing for me." posts.

Cecilia looks like an average residential area in Russia.

glinkot • today at 12:40 PM

The creation really is amazing. I harnet heard of the book but got a long way through it!

mcphage • today at 2:43 PM

What is this for? It doesn't deepen the understanding of the book. The illustrations aren't attractive on their own. They're not a very good representation of the descriptions in the book.

this is amazing, wonder how much better it's going to get in a year from now

swiftcoder • today at 1:49 PM

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.

Thanks, I hate it. I imagine Calvino turning in his grave at such an abdication of human imagination.

"Attention whore" used to mean someone who makes garbage to get attention. Now it's a machine that uses attention to make garbage.

gexaha • today at 2:21 PM

Well it still has the trademark "colored left-side of the boxes" ai slop, but otherwise looks (and sounds!) very impressive.

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 :).
