I just want to say this isn't just amazing -- it's my new favorite map of NYC.

It's genuinely astonishing how much clearer this is than a traditional satellite map -- how it has just the right amount of complexity. I'm looking at areas I've spent a lot of time in, and getting an even better conceptual understanding of the physical layout than I've ever been able to get from satellite (technically airplane) images. This hits the perfect "sweet spot" of detail with clear "cartoon" coloring.

I see a lot of criticism here that this isn't "pixel art", so maybe there's some better term to use. I don't know what to call this precise style -- it's almost pixel art without the pixels? -- but I love it. Serious congratulations.

I was extremely excited until I looked closer and realized how many of these look like ... well AI. The article is such a good read and would recommend people check it out.

Feels like something is missing... maybe just a pixelation effect over the actual result? Seems like a lot of the images also lack continuity (something they go over in the article)

Overall, such a cool usage of AI that blends Art and AI well.

This isn't creative. It's just a slog. Every creative field - animation, video, software - is full of these tedious tasks. Of course, there’s a case to be made that the very act of doing this manual work is what refines your instincts - but I think it’s more of a “Just So” story than anything else. In the end, the quality of art is defined by the quality of your decisions - how much work you put into something is just a proxy for how much you care and how much you have to say.

Great insights here, thanks for sharing. That opening question really clicked for me.

This is an immensely cool thing that fits the space I imagine for AI within art. And I am not someone that likes framing AI output as art.

If you had instead drawn this, there would be charm and fun details EVERYWHERE. Little buildings you know would have inside jokes, there would be references snuck into everything. Who YOU are would come through, but it would also be much smaller.

This is HUGE, and the zoomed out view is actually an insanely useful map. It's so cool to see reality shifted into a style like this, and there's enough interesting things in "real new york" to make scrolling around this a fun thing to do. I have no impression of you here other than a vague idea you like the older sim city games BUT I have a really interesting impression of NYC.

IMO, that's two totally different pieces of art, with two totally different goals. Neither takes away from the other, since they're both making something impactful rather than one thing trying to simulate the impact of the other. Really nice job with this.

So, wait: this is just based on taking the 40 best/most consistent Nano Banana outputs for a prompt to do pixel-art versions of isometric map tiles? That's all it takes to finetune Qwen to reliably generate tiles in exactly the same style?

Also, does someone have an intuition for how the "masking" process worked here to generate seamless tiles? I sort of grok it but not totally.

Sorry about the hug of death - while I spent an embarassing amount of money on rented H100s, I couldn't be bothered to spend $5 for Cloudflare workers... Hope you all enjoy it, it should be back up now

> This project is far from perfect, but without generative models, it couldn’t exist. There’s simply no way to do this much work on your own,

Maybe, though a guy did physically carve/sculpt the majority of NYC: https://mymodernmet.com/miniature-model-new-york-minninycity...

Want to thank you for taking the time to write up the process.

I know you'll get flak for the agentic coding, but I think it's really awesome you were able to realize an idea that otherwise would've remained relegated to "you know what'd be cool.." territory. Also, just because the activation energy to execute a project like this is lower doesn't mean the creative ceiling isn't just as high as before.

Not working here, some CORS issue.

Firefox, Ubuntu latest.

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://isometric-nyc-tiles.cannoneyed.com/dzi/tiles_metadat.... (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 429.

Edit: i see now, the error is due to the cloudflare worker being rate limited :/ i read the writeup though, pretty cool, especially the insight about tool -> lib -> application

I was most surprised by the fact that it only took 40 examples for a Qwen finetune to match the style and quality of (interactively tuned) Nano Banana. Certainly the end result does not look like the stock output of open-source image generation models.

I wonder if for almost any bulk inference / generation task, it will generally be dramatically cheaper to (use fancy expensive model to generate examples, perhaps interactively with refinements) -> (fine tune smaller open-source model) -> (run bulk task).

I lived in NYC for 8 years and have worked there for almost 20 years.

Absolutely loved zooming around to see:

- my old apartment

- places I've worked

- restaurants and rooftop lounges I've been to etc

The explanation of how this was put together was even cooler: https://cannoneyed.com/projects/isometric-nyc

Probably the best pre-AI take of the isometric pixel art NYC is poster from the art collective eboy. In the early 2000s their art was featured in MoMA (but I don't remember the NYC poster specifically).

Author here: Just got out of some meetings at work and see that HN is kicking my cloudflare free plan's butt. Let me get Claude to fix it, hold tight!

Hey, engineer at Oxen.ai here. Glad the fine-tuning worked well for this project! If anyone has questions on that part of it we would be happy to answer.

We have a blog post on a similar workflow here: https://www.oxen.ai/blog/how-we-cut-inference-costs-from-46k...

On the inference cost and speed: we're actively working on that and have a pretty massive upgrade there coming soon.

Great project! Just wanted to talk about the "/ The edit problem" section in the blog post - it's almost entirely false. Inpainting (when you provide a mask) has existed for years, and for good edit models (such as Nano Banana Pro) you can annotate the image, and it'll only edit one part, keeping the rest almost entirely consistent. The same goes for other top editing models like Flux 2, Seedream 4.5 and so on.

Transparency also exists, e.g. GPT Image does it, and Nano Banana Pro should have it supported soon as well.

I created an account just to say that your map is amazing! It's beautiful and very interesting to look at, because of all the details. Thank you for documenting your method of creating this! I've been looking for a way to create a similar map for the island I'm living at, and maybe your method will work for this. Thank you so much for documenting the steps!

There's absolutely no pixel art anywhere in the entirety of the map.

amazing work!

100 people built this in 1964: https://queensmuseum.org/exhibition/panorama-of-the-city-of-...

One person built this in the 21st century: https://gothamist.com/arts-entertainment/truckers-viral-scal...

AI certainly let you do it much faster, but it’s wrong to write off doing something like this by hand as impossible when it has actually been done before. And the models built by hand are the product of genuine human creativity and ingenuity; this is a pixelated satellite image. It’s still a very cool site to play around with, but the framing is terrible.

Very impressive result! are you taking requests for the next ones? SF :D Tokyo :D Paris :D Milan :D Rome :D Sydney :D

Oh man...

This is so cool! Please give me a way to share lat/long links with folks so I can show them places that are special to me :)

This is really wonderful. Thanks for doing it!

I especially appreciated the deep dive on the workflow and challenges. It's the best generally accessible explication I've yet seen of the pros and cons of vibe coding an ambitious personal project with current tooling. It gives a high-level sense of "what it's generally like" with enough detail and examples to be grounded in reality while avoiding slipping into the weeds.

Appreciate that writeup. Very detailed insights into the process. However those conclusions left me on the fence about whether I 'liked' the project. The conclusions about 'unlocking scale' and commodity content having zero value. Where does that leave you and this project? Does it really matter that much that the project couldn't exist without genAI? Maybe it shouldn't exist then at all. As with alot of the areas AI touches, the problem isn't the tools or use of them exactly, it's the scale. We're not ready for it. We're not ready for the scale of impact the tech touches in multitude of areas. Including the artistic world. The diminished value and loss of opportunities. We're not ready for the impacts of use by bad actors. The scale of output like this, as cool as it is, is out of balance with the loss of huge chunk of human activity and expression. Sigh.

This is awesome, and thanks so much for the deep dive into process!!

One thing I would suggest is to also post-process the pixel art with something like this tool to have it be even sharper. The details fall off as you get closer, but running this over larger patch areas may really drive the pixel art feel.

https://jenissimo.itch.io/unfaker

First thing I wanted to do was click the monster button in SimCity 2000

This is a fantastic piece of work, AI or no!

Feature idea: For those of us who aren't familiar with The City, could you allow clicks on the image to identify specific landmarks (buildings, etc.)? Or is that too computationally intensive? I can identify a few things, but it would sure be nice to know what I'm looking at.

Failed to load tiles: NetworkError when attempting to fetch resource.

> I’m not particularly interested in getting mired down in the muck of the morality and economics of it all. I’m really only interested in one question: What’s possible now that was impossible before?

Upvote for the cool thing I haven’t seen before but cancelled out by this sentiment. Oof.

> Slop vs. Art

> If you can push a button and get content, then that content is a commodity. Its value is next to zero.

> Counterintuitively, that’s my biggest reason to be optimistic about AI and creativity. When hard parts become easy, the differentiator becomes love.

Love that. I've been struggling to succinctly put that feeling into words, bravo.

Insane outcome. Really thoughtful post with insights across the board. Thanks for sharing

You mentioned needing 40k tiles and renting a H100 for 3$/hour at 200tiles/hour, so am I right to assume that you spend 200*3=600$ for running the inference? That also means letting it run 25 nights a 8 hours or so?

Cool project!

"map of NYC" does not include Staten Island. That's how we like it

Would it be simple to modify this to make a highly stylized version of NYC instead? Like post apocalyptic NYC or medieval NYC, night time NYC, etc. because then that would have some very interesting applications

This is incredible, I love it. It would be great to be able to overlay OSM data over it for those of us who aren't that familiar with the city and would like to know more about certain areas or places

This is awesome, thanks for sharing this!

I am especially impressed with the “i didn’t write a single line of code” part, because I was expecting it to be janky or slow on mobile, but it feels blazing fast just zooming around different areas.

And it is very up to date too, as I found a building across the street from me that got finished only last year being present.

I found a nitpicky error though: in Brooklyn downtown, where Cadman Plaza Park is, your webite makes it looks like there is a large rectangular body of water there (e.g., a pool or a fountain). In reality, there is no water at all, it is just a concrete slab area.

While impressive on a technical level, I can't help but notice that it just looks...bad? Just a strange blurry mess that only vaguely smells of pixelart.

Makes me feel insane that we're passing this off as art now.

Nice work! But not all of NYC. Where's the rest of Staten Island?

Really great work! All that's left is a day/night cycle, some underground infra views, and (obviously) a way to play the SimCity 3000 soundtrack over it

> I simply booted up a VM with an H100, ssh’d into it with Cursor, and prompted the agent to set up an inference server that I could ping from my web generation app. What used to take hours or days of painful, slow debugging now takes literally minutes.

an awesome takeaway from this is that self-hosted models are the future! can't wait for hardware to catch up and we can do much more experiments on our laptops!

Awesome. There was a company in China, eDuShi (E都市), doing this for a whole bunch of Chinese cities back in the day: https://www.flickr.com/photos/seeminglee/4112874847

Really fun to fly around, find my old apartment building etc.

It would be neat if you could drag and click to select an area to inpaint. Let's see everyone's new Penn Station designs!

Would guess it'd have to be BYOK but it works pretty well:

https://i.imgur.com/EmbzThl.jpeg

Much better than trying to inpaint directly on Google Earth data

Does anyone remember a Chinese website that did something similar? IIRC it was one of the selectable rendering modes of a Google Maps equivalent.

Edit: this submission has a few links that could be what I had in mind but most of them no longer work: https://news.ycombinator.com/item?id=2282466

Holy damn, this map is a dream and the best map of NYC I've ever seen!

It's as if NYC was built in Transport Tycoon Deluxe.

I'll be honest, I've been pretty skeptical about AI and agentic coding for real-life problems and projects. But this one seems like the final straw that'll change my mind.

Thanks for making it, I really enjoy the result (and the educational value of the making-of post)!

Highly recommend reading the blog post too. It helped me see some of the limitations of this approach and I thought it was useful,

Just read your bio on cannoneyed.com and want to let you know I was a huge fan of The Machine. I always wondered what happened to the group then found out about Luttrell.

Cool seeing where you ended up.

One thing I learned from this is that my prompts are much less detailed than what author has been using.

Very cool work and great write up.

Someone else posted this on HN a while back -- https://github.com/Hugo-Dz/spritefusion-pixel-snapper

Maybe you can use that^ to snap the pixels to a perfect grid

This is delightful. It scratches that SimCity itch while still being recognizably New York. I ended up losing track of time exploring my old neighborhood and landmarks, and it somehow conveys the city's scale and quirks better than a satellite view. Thanks for sharing it.

Truly amazing work! I only had time to scan quickly your write-up but I'll try to read it entirely, it's very interesting thank you!

As you say: software engineering doesn’t go away in the age of AI - it just moves up the ladder of abstraction ! At least in the mid term :)

Just curious, about how long did this project take you? I don't see that mentioned in the article.

The progressive loading of the tile images really goes great with the pixel art style. Nice touch!

Looks pretty amazing, especially a bit zoomed out!

The 3D/street view version is an obvious and natural progression from here, but from what I've read in your dev log, it's also probably a lot of extra work.

Nice, very cool!

Reminds me of https://queensmuseum.org/exhibition/panorama-of-the-city-of-...

I thought that other link recently of those guys who manually built new York city in Minecraft completely to scale more impressive.

That's what we call a monk's job in Holland. Kudos

This is one of the coolest things I've ever seen. Massive kudos to you. I am forwarding to all NYers I know. It gives me chills to relive specific places, though I'm far from the city now.

This is an incredible piece of work that I had a blast exploring!

I must admit I spent way too much time finding landmarks I visited when I last holidayed from Australia. Now I'm feel nostalgic.

Thanks so much for sharing!

To take it a step further it would be super cool to so rhiw figure out the roadway system from the map data and use the buildings as masks over the roads and have little simulated cars driving

Would be cool if you could adjust the sun's position & see the effect on shadows.

Could even extend it to add a "night mode" too, though that'd require extensive retexturing.

Wow, this is absolutely amazing! This is the kind of project I am trying to do with agents, but of course I'm really far from this, but you motivated me to do better!

This is very cool, it would be awesome if I could rotate it as well by 90 degree increments to peek at different angles! I loved RCT growing up so this is hitting the nostalgia!

I love it, and I want it for my city, and hell the whole world!

Looks more like trimetric projection, but cool nevertheless.

A bit tangential but i really think the .nyc domain is underappreciated.

SF/Mountain View etc don't even have one! you get a little piece of the NYC brand just for you!

This is such a cool concept. props to you for building it.

This is huge!

At first I thought this was someone working thousands of hours putting this together, and I thought: I wonder if this could be done with AI…

I too am amazed by the detail. I see things now, that I never saw before, in areas I'm intimately familiar with.

I'm on holiday in NY now - this is so cool

Amazing. Took forever but I found my building in Brooklyn as well as the nearby dealership, gas station, and public school.

Seems to have been hugged to death as of now

Really slick. Let’s see the AI open it up so we can use it to generate a similar map for anyplace on Earth :)

Some people reported 429 - otherwise known as HN hug of death.

You probably need to adjust how caching is handled with this.

Very gorgeous and creative! Any plans to attempt other isometric cities? (Like SF, LA, Paris, London)

This is fantastic, can't overstate how revolutionary this would be for gaming development.

I love it! Such a SimCity 2000 vibe!

Maybe I'm just missing it somewhere but does anyone see what the licence for this map is?

I see you used Gemini-CLI some but no mention of Antigravity. Surprising for a Googler. Reasons?

Why is so much NJ on the map?

> But at the end of the day, the last 10% always takes up 90% of the time and, as always, the difference between good enough and great is the amount of love you put into the work.

Nicely put.

Very cool. Street names with an on/off toggle would be nice.

Great job, I love the M Machine too. Good music and visuals.

This is so cool. I love the 80s cartoon feel of the map.

You definitely captured the SimCity vibe. Well done!

Very cool! What's your license on this stuff?

Amazing map! Where is the rest of Staten Island?

Makes me realize how much I love New York, thank you.

Great work, I loved the in depth tech explanation

This on top of Subway Builder would be incredible

This is kind of beautiful. Great work! I mean it.

Amazing idea and implementation, bravo

what an amazing feat of artwork and such a fine writeup as well. learnt a ton! thank you for this

This doesn't really look like pixel art; it looks like you applied a (very sophisticated) Photoshop filter to Google Earth. Everything is a little blurry, and the characteristic sharp edges of handmade pixel art (e.g. [0]) are completely absent.

To me, the appeal of pixel art is that each pixel looks deliberately placed, with clever artistic tricks to circumvent the limitations of the medium. For instance, look at the piano keys here [1]. They deliberately lack the actual groupings of real piano keys (since that wouldn't be feasible to render at this scale), but are asymmetrically spaced in their own way to convey the essence of a keyboard. It's the same sort of cleverness that goes into designing LEGO sets.

None of these clever tricks are apparent in the AI-generated NYC.

On another note, a big appeal of pixel art for me is the sheer amount of manual labor that went into it. Even if AI were capable of rendering pixel art indistinguishable from [0] or [1], I'm not sure I'd be impressed. It would be like watching a humanoid robot compete in the Olympics. Sure, a Boston Dynamics bot from a couple years in the future will probably outrun Usain Bolt and outgymnast Simone Biles, but we watch Bolt and Biles compete because their performance represents a profound confluence of human effort and talent. Likewise, we are extremely impressed by watching human weightlifters throw 200kg over their heads but don't give a second thought to forklifts lifting 2000kg or 20000kg.

OP touches on this in his blog post [2]:

   I spent a decade as an electronic musician, spending literally thousands of hours dragging little boxes around on a screen. So much of creative work is defined by this kind of tedious grind. [...] This isn't creative. It's just a slog. Every creative field - animation, video, software - is full of these tedious tasks.

Looks badly AI generated.

It looks like simcity4!

This is crazy good.

Sim City, NYC edition

this makes me want to play simcity again! really cool

Hugged to death? :(

I don't understand why an interesting demo is buried here inside of some of the most ridiculous propaganda I've ever read on the topic of genAI.

It really makes me not have any interest in the actual thing you're showing.

Imagine if Wendy Carlos wrote an article about how it's cool she could use this new piece of technology called a Moog Modular synthesizer to create a recording of Bach, and now harpsichords are dead, acoustic instruments suck, and all Baroque music will be made on modular synthesizers forever more.

Unfortunately with AI it's much worse because it's more like if Wendy Carlos has slurped up all Baroque music ever recorded by everyone and then somehow regurgitated that back out as slop with some algorithmic modifications.

I'm sorry, I'm unable to accept that's where we're at now.

"Napoleon may have once said “quantity has a quality all its own”."

Nope, It was Stalin who said that in regards to his "meatwave" strategy.

Really nice.
