First off, Opus 5.5 built working weights and code with only two prompts:
1. Read this article and any relevant source code: https://divagr.com/blog/qwenputer. Then explore if you could emulate the chip and ram in a Nintendo Entertainment System (as people do today with FPGAs in MISTRs) using this technique. If so, what size model would you have to build and if you could use smaller faster ones, could you get it to be at the standard clockspeed.
It returned charts well illustrating any model would be _slow_. But it's still fun, so the second prompt was:
2. I think we should build it! Just for fun. It's okay if it's not fast. We want to be able to have the weights, and a cli to run them that we can point at a ROM.
Now while this was an _epic_ run by Opus (5.5 is a crazy capable model), this is a surprisingly well-structured challenge.
There is a long-lived and incredible community of classic gaming emulation work online for it to reference. And that community has created…conformance tests! Opus found them and built against one, that has >3k golden instructions: https://github.com/christopherpow/nes-test-roms/blob/master/...
Also, there is the original Qwenputer repo that Opus used to drive the weight writing. That was essential.
But this is a great example of what these models can do with proper reference materials, great specs, conformance tests, and clear direction.
> There is a long-lived and incredible community of classic gaming emulation work online for it to reference. And that community has created…conformance tests! Opus found them and built against one, that has >3k golden instructions
I'm doing something similar but not for an emulator, using tests other projects in a similar space use to validate things.
I also know a friend that feeds Claude Gherkin formatted test criteria, and apparently that yields insanely good Claude output.
This opens up so many interesting opportunities. In principle one could compile a small VM inside the LLM weights. The VM can host for example a Python interpreter, a shell and tools like sed, cat, grep etc. Instead of LLMs having to do slow autoregressive token emission with the current "external" tool calling, it could literally execute everything except web search, inside the LLM, with just matmul operations. You could probably optimise this so it runs in batches. You could have a gdb like application that can step through the LLM forward pass. Anyway, just a crazy thought. Have a great weekend everyone!
>Overall, nesformer runs 150–290× slower than the real console.
I like these kinds of projects because it helps to show the massive compute requirement between LLMs and ordinary programs.
A while back I saw some people saying we would just have LMMs hallucinate an entire operating system every single frame. I guess technically it's now proven to be technically possible, but it would be thousands of times slower while requiring thousands of times more compute (a multi-million x difference from an ordinary OS!).
This is a bit different though. It’s using transformer architecture to emulate almost at the circuit level. It’s probably even more inefficient than something that was trained to emulate a cpu, but with the advantage of actually being an exact emulation rather than learned approximation.
It’s a bit like when a human brain remembers facts, if you sat down and computed the hash values of the thing you were trying to remember, and traced out a DB lookup in your mind, it’d be a lot slower than just “oh yeah I remember that”.
We're in a really interesting world where "anything can run anything." Like, in theory, you could get Doom to run on a Cerebras that's specifically laid out for $specific_model architecture, by swapping the weights it holds in SRAM. Just like we're currently running $specific_model on GPUs that were designed for games in the first place.
To misquote a certain YouTuber: LLMs are just games, unlimited games, but no games.

Gosh. That would be a very silly use of an LLM.
Bad use of any AI, even image/video models which are certainly less wrong than this. Stuff like DLSS show we're getting stuff that could generate a game's graphics frame-by-frame, but even though it's possible to have an entire game environment (not just graphics, everything) done by an AI, such things demo better than they play due to temporal coherency.
That said, having an AI make the code for each thing as you need it, might work somewhat OK eventually. Wouldn't trust it today (security, data integrity, and a tendency to cheat on tests), but eventually it could happen.
> Stuff like DLSS show we're getting stuff that could generate a game's graphics frame-by-frame
A key point of DLSS (5) is that it is significantly guided by ground truth rasterization or raytracing info. It's not intended to replace graphics pipelines, it augments them to produce more detailed surfaces and interpolate frames more efficiently than calculating all of it traditionally is. But you have to calculate some of it to get these results, it can't be a purely AI solution without looking incoherent.
This is exactly like if someone implemented a CPU using nothing but CSS animations. Maybe a fun way to teach about turing completeness, but pretty meaningless otherwise.
Hard disagree on it being meaningless. Just showing that this is now possible and providing the details on how it was accomplished makes it invaluable to builders.
1) Have a single person vibe together a computationally inefficient solution in 1 month that runs transformers on some backend.
2) Hire a team to work for 2 years to design, perfect, optimize, plan, revise, and architect a solution.
The risk/reward for 1) is extremely better than 2). Given the turnover for entertainment in this day and age it doesn't make sense to do all this complex stuff.
It would be much better to use LLMs to create ordinary programs than to use an LLM over and over to emulate something that's thousands or millions of times more efficient.
You can't generalize and say that 1 is better than 2, it depends entirely on what you are developing, for whom and for what purpose. For a one-off dumb thing for a few people 1 is fine, for anything at scale, 2 is likely better.
How do you vibe a transformer solution without the existing real solution, which would be needed to generate the training data.
These are just machines for ripping off existing games/programs with mostly accurate simulations. You can't vibe together a transformer of something that doesn't exist with meaningful control over the results.
That's the case right now--but what might a customized model tailored only for a narrow set of OS functions behave like? I suspect its achievable with a lot less compute.
Now is that a desirable product? Would it succeed on the merits in the marketplace? Maybe it would...
As an example, is it faster to multiply 2 numbers using a single MUL instruction or multiply matrices with millions (or billions) of elements multiple times? Multiply that overhead by every single thing you do and that's the overhead of using an LLM to emulate a program.
Code isn't going anywhere. It can be literally billions or trillions of times more efficient than an AI, and as AIs scale up that number just continues to grow and can completely plausibly hit quadrillions in our lifetime. What relationships humans have with code is a completely different question, but the idea itself isn't going anywhere. Anyone who thinks otherwise has failed to grasp just what producing a single token from an AI actually entails.
The ones we're not thinking about is the computer program abstraction layer in our brains. I think consciously thinking about an equation in our brains is the LLM layer equivalent, we're reasoning about it with language logic or models of our spatial senses (the unconscious calculations)
Perhaps, but it doesn't indicate anything new or interesting about cognition or biology.
For example, Minecraft in Minecraft [0] is (while impressive) slow and inefficient too, but it doesn't tell us much about humans except that some of them are weirdly ambitious in their projects.
It would be a natural extension of the current work in software. Every layer of abstraction/web/scripting language adds seemingly 10x in both ram and processing time, undoing the advancement of 1000x faster processors and ram increases.
But at some point we’re hitting a wall here. If we want our software to undo 100,000x more processing powers, we need that llm software emulation layer.
I love these hacks, even though from an efficiency point of view it is horrifying to my assembly-code-golfing-brain. And it also gives some new appreciation for how much more efficient deterministic programs are compared to AI.
The day is coming when we have widespread local inference on super powerful and efficient hardware and people will ask it what time the store closes, get distracted, and then ask it again instead of scrolling up.
> I really hate looking at the terminal and don’t know how to customize it to make it more readable
On a comment where you discuss a powerful tool for looking up information, you claim ignorance about a piece of information that same tool could explain to you! What the heck!
I believe GP is making the point that tokens are expensive atm so we are better at conserving them (the scroll back part), but soon it'll be so inexpensive or even free that we won't bother.
18 months ago: it can do some things but it’s generally not useful.
12 months ago: wow; this can write ok code that a human has to do a lot of review to make sure it’s ok.
6 months ago: holy fuck I’m shipping great stuff with only the occasional redo.
3 months ago: Jesus Christ this is actually pretty fucking great. I have to work entirely differently; becoming a manager of my single agent launching sub agents.
1 month ago: my god I am shipping more, faster, and more useful than ever.
Today: we have fleets of highly effectively domain expert agents working entirely autonomously and shifting between fleets depending on domain, available usage remaining, and we’re shipping 10x with 100% better reviews than before—expanding by the day and self-improving its own harness.

Next week: the agents will prioritize code golf.
The week after that: everything is written in ASM.
We’ll come full circle in 3y
e: fyi; this is my personal progression with LLMs.
This is what I don't get with the kind of posts you are replying to.
I have experienced directly what the evolution of cloud based software, and now AI based tooling, has done to team sizes on delivery projects.
Cannot understand how they don't get how all the performance improvements directly correlates to smaller team sizes, in shareholders driven economy.
So far I have been lucky, and just hope to have enough savings when time comes, as finding jobs after 50s wasn't already easy without having to add AI on top.
Most of the world does NOT optimise for efficiency, particularly at the big end. Really big hyperscale companies (and some startups) are unusual because they at least sort of try, most of the world is not even trying.
The org structure is optimised to reduce or even minimise individual agency, explicitly at the cost of efficiency.
Teams have fiefdoms, private repos that the rest of the org can't see. You are not granted permission to see what permissions you have. Byzantine department structures. Shipping "hello world" to production takes 3-6 months and nobody can imagine it working any other way.
There's actually no central directory of teams or processes. To get anything meaningful done, you need the co-operation of maybe 8 teams but there's no consistent way to engage them all. You have to negotiate with them all in different ways, they're like little warlords, sitting and guarding access to some vital resource you need. They have established a ticket-based interface with a 7 day SLA on top of a perfectly good vending API that could do what you need in seconds. Sometimes a blocking team has a 3 month backlog so your project will just have to wait.
Everything is always in the process of being restructured, so no end to end 6 month process happens the same way every time.
These organisations could use AI to run the end to end process in minutes. Heck, they could just put APIs on top of what they already have. But the way they WANT to use it is to keep doing what they're doing but with EVEN MORE form filling and paperwork.
You would think they would get outcompeted, but no. The "IT organisation" sits like a brain slug on top of an enterprise with substantial regulatory, capital and execution moats.
Big cuts of course do happen in these places, but it's often for optics (we need to signal that we care about efficiency, and AI is a great excuse). But you can't protect yourself by being efficient and good at your job, because the cuts were not about output.
Because I don't live in a world where my team needs to grow for me to feel more successful? My teams have been small and tight-knit at every place I've been an Eng leader. I left a job with 13 engineers and they're at >90 now, apparently doing less; but, that's just what I hear second-hand.
I unfortunately have been in enough situations where team sizes get to shrink, unless there is some escalation going on.
First it was offshoring, then managed cloud environments and servless, followed by ready made SaaS products, low code/no code iPaaS cloud products, and now agentic runtimes.
The ones doing content translations, asset management were the first, followed by classical infrastructure people, then most backend roles, and so it goes.
Not everyone makes the transition. In the rise of AWS, someone I know's last task at this one company, a company they'd poured their heart and soul into; it was to move everything off the on-prem servers that he'd procured and the company had been running in for years. He moved it all onto AWS, got rid of that hardware, and then he was out of a job.
> I want to do MORE with the same amount of folks.
So do I, but I've been in two companies that had to let me go because the investors said they didn't want my role to exist any more. Plus two other roles where the company straight up ran out of money.
I think it is because programmers are not that good at economy or running a business. Their bosses are though and they don't see a productivity tool, but a way to reduce their costs.
Speaking of code golf, I had it optimize Diskitude into a <8 kb (still uncompressed) executable, add some features, and improve scanning performance all while increasing size. An LLM will gladly make extremely optimized software, you just have to ask for it.
> The week after that: everything is written in ASM.
This is an genuinely good minimalist good editor that is created in mostly assembly that was created with the help of AI[0]
I maintain a fork of it which basically adds scratchpad ability to it and is something that I use daily myself for what it's worth[1]
My fork was created with the help of GLM 5.3 (an open-weights model)
The future is already here in some sense. I could in theory add more features but I intentionally add not more features because asm is still slightly difficult for it to write but in some sense the tradeoff has been/could be worth it. It was more of an experiment really and I am really impressed by it.
in many ways, forcing AI to write asm does make you now think intentionally of features and ironically prevents feature creep and makes you think of stability of the product (atleast right now for me anyways)
i wish this was my experience, it's basically the opposite. im shipping a little faster -- but spending endless amounts of time reviewing LLM-generated code that usually isnt production ready.
Once our compute base shifts from silicon to human brains grown in vats, you'll be thankful you can run all your old deterministic compute tasks on flesh neurons!
I expected this to only simulate the CPU itself, but was surprised to find they actually simulate the RAM as well (contained in the model itself via the gated deltanet architecture). So in my understanding, the CPU, ROM, and RAM are all handled internally by the model, and the only inputs after initialization are the controller events, wild.
> nesformer builds on Qwenputer by Divyansh Agrawal, which compiled a CHIP-8 and then a RISC-V CPU into Qwen3.5-4B. It reuses Qwenputer's compiler and its central trick: the model's Gated DeltaNet state is the machine's memory
This is amazing, love it! Qwenputer is very cool too
Do you test every possible input/output combination on any CPU?
No, because that would be impossible.
You perform a series of more specific tests. In this case, it's "working" in so far as that Super Mario Bros. appears to be playable, for example.
Does not mean that it behaves perfectly according to some spec, or identical to another CPU (like the NES's 6502), of course, but it's clearly a working CPU to some 6502-compatible extent.
This is a case where we basically did test it on everything! Because the emulation community maintains conformance tests with over 3k of golden instructions. (And this is why Opus was able to so effectively build it; it found the tests)
Yeah, but that still doesn’t mean there aren’t theoretical bugs. Testing every input would effectively mean testing every stimulus, which is combinatorially impossible. You might still have subtle timing bugs, bugs with very uncommon instruction sequences etc.
But my point was exactly that the (extremely vastly) smaller subset of tests that you performed is more than enough to proclaim a CPU to be “working”.
> It also helps combat the "LLMs ArE nOt DeTeRmInIsTiC" complaints.
Reality says otherwise, especially from those who run LLMs in production at a large scale. Hacks such as baking in the weights with tiny experiments doesn't disprove anything.
The same LLM boosters also continue to repeat one of the biggest misconceptions: "sEt TeMperaTurE tO zERo tO aChiEvE fUlL dEterMinIsm."
Sometimes projects have no point other than to show what can be done – and the pure thrill of doing is an end in itself … but I agree with you in the "so what" sense here … I feel like with this project there is meant to be a point (other than play for the sake of play and art for the sake of art and coding for the sake of coding) but I'm not seeing it either?
HN loves slop meetoo projects without questioning the details. With close inspection it is an overly complicated version of this paper [0] on neural turing machines.
This concept was hyped up (because DeepMind) for a while at the time and in reality it amounted to nothing. This is just the second reincarnation of a similar concept but with added extra saturated slop and hype on top.
This is like when people used to make tetris using only CSS or whatever in the 2010s. But it's less impressive because Claude Code can slop it out in an afternoon.
A couple thoughts on the process here…
First off, Opus 5.5 built working weights and code with only two prompts:
1. Read this article and any relevant source code: https://divagr.com/blog/qwenputer. Then explore if you could emulate the chip and ram in a Nintendo Entertainment System (as people do today with FPGAs in MISTRs) using this technique. If so, what size model would you have to build and if you could use smaller faster ones, could you get it to be at the standard clockspeed.
It returned charts well illustrating any model would be _slow_. But it's still fun, so the second prompt was:
2. I think we should build it! Just for fun. It's okay if it's not fast. We want to be able to have the weights, and a cli to run them that we can point at a ROM.
Now while this was an _epic_ run by Opus (5.5 is a crazy capable model), this is a surprisingly well-structured challenge.

Also, there is the original Qwenputer repo that Opus used to drive the weight writing. That was essential.
But this is a great example of what these models can do with proper reference materials, great specs, conformance tests, and clear direction.

Truly amazing. Quite thought provoking how it was helped by having high quality oracles. Eg. Qwenputer & good NES reference materials.
I guess humans need their oracles too: teachers, encyclopaedias, degrees, phds.
Bravo, awesome project, really creative!
This opens up so many interesting opportunities. In principle one could compile a small VM inside the LLM weights. The VM can host for example a Python interpreter, a shell and tools like sed, cat, grep etc. Instead of LLMs having to do slow autoregressive token emission with the current "external" tool calling, it could literally execute everything except web search, inside the LLM, with just matmul operations. You could probably optimise this so it runs in batches. You could have a gdb like application that can step through the LLM forward pass. Anyway, just a crazy thought. Have a great weekend everyone!

Let's say you are developing a product, choose 1:
1) Have a single person vibe together a computationally inefficient solution in 1 month that runs transformers on some backend.
2) Hire a team to work for 2 years to design, perfect, optimize, plan, revise, and architect a solution.
The risk/reward for 1) is extremely better than 2). Given the turnover for entertainment in this day and age it doesn't make sense to do all this complex stuff.

Thousands or millions of times less energy used is a whole lot better for the environment, too.

The ones doing content translations, asset management were the first, followed by classical infrastructure people, then most backend roles, and so it goes.
Not everyone makes the transition. In the rise of AWS, someone I know's last task at this one company, a company they'd poured their heart and soul into; it was to move everything off the on-prem servers that he'd procured and the company had been running in for years. He moved it all onto AWS, got rid of that hardware, and then he was out of a job.
> I want to do MORE with the same amount of folks.
So do I, but I've been in two companies that had to let me go because the investors said they didn't want my role to exist any more. Plus two other roles where the company straight up ran out of money.
It's not always up to us.
HR meeting in room #3, please bring your coat with you.
I think it is because programmers are not that good at economy or running a business. Their bosses are though and they don't see a productivity tool, but a way to reduce their costs.
What about their comment says they don’t understand that?
The whole positive content on the productivity outcomes.
I can’t decipher your reply.
I think that's this week
Speaking of code golf, I had it optimize Diskitude into a <8 kb (still uncompressed) executable, add some features, and improve scanning performance all while increasing size. An LLM will gladly make extremely optimized software, you just have to ask for it.

Also “1 month ago,” but s/ASM/Rust
> The week after that: everything is written in ASM.
This is an genuinely good minimalist good editor that is created in mostly assembly that was created with the help of AI[0]
I maintain a fork of it which basically adds scratchpad ability to it and is something that I use daily myself for what it's worth[1]
My fork was created with the help of GLM 5.3 (an open-weights model)
The future is already here in some sense. I could in theory add more features but I intentionally add not more features because asm is still slightly difficult for it to write but in some sense the tradeoff has been/could be worth it. It was more of an experiment really and I am really impressed by it.
in many ways, forcing AI to write asm does make you now think intentionally of features and ironically prevents feature creep and makes you think of stability of the product (atleast right now for me anyways)

i wish this was my experience, it's basically the opposite. im shipping a little faster -- but spending endless amounts of time reviewing LLM-generated code that usually isnt production ready.
Once our compute base shifts from silicon to human brains grown in vats, you'll be thankful you can run all your old deterministic compute tasks on flesh neurons!
I expected this to only simulate the CPU itself, but was surprised to find they actually simulate the RAM as well (contained in the model itself via the gated deltanet architecture). So in my understanding, the CPU, ROM, and RAM are all handled internally by the model, and the only inputs after initialization are the controller events, wild.
This has the nice side benefit of letting the 1gb of weights compress down to ~3mb (since it’s mostly empty)
B-but "there's no such thing as a Nintendo".

"Mario thanks you".
> nesformer builds on Qwenputer by Divyansh Agrawal, which compiled a CHIP-8 and then a RISC-V CPU into Qwen3.5-4B. It reuses Qwenputer's compiler and its central trick: the model's Gated DeltaNet state is the machine's memory
This is amazing, love it! Qwenputer is very cool too
It mentions a greedy decoder in the readme, I'm curious what would happen if you run it stochastically with T>0. Vibe NES? Or does it just crash.
I imagine it would prove really difficult to keep generating valid instructions.
I'm guessing it's safe to say that LLMs can run Doom.
Woowww this is cool, not trained is even cooler--maybe I'm probably a bit naive, but to me it demonstrates an understanding of how an LLM can compute
Has anyone tried training a diffusion model for speed ?
How do they know it's "working"?
Did they test every possible input/output combination?
Doesn't work for all cartridges (I didn't run Opus that long, but it could keep going). Works with Super Mario.
But to answer your question, it's in the readme: https://github.com/dbreunig/nesformer#how-it-was-checked
Do you test every possible input/output combination on any CPU?
No, because that would be impossible.
You perform a series of more specific tests. In this case, it's "working" in so far as that Super Mario Bros. appears to be playable, for example.
Does not mean that it behaves perfectly according to some spec, or identical to another CPU (like the NES's 6502), of course, but it's clearly a working CPU to some 6502-compatible extent.
This is a case where we basically did test it on everything! Because the emulation community maintains conformance tests with over 3k of golden instructions. (And this is why Opus was able to so effectively build it; it found the tests)
Yeah, but that still doesn’t mean there aren’t theoretical bugs. Testing every input would effectively mean testing every stimulus, which is combinatorially impossible. You might still have subtle timing bugs, bugs with very uncommon instruction sequences etc.
But my point was exactly that the (extremely vastly) smaller subset of tests that you performed is more than enough to proclaim a CPU to be “working”.
I guess I don't understand the point of this. Of course a set of digital logic circuits can be reduced to a set of weights. Am I missing something?
Apparently it's news to some people. It also helps combat the "LLMs ArE nOt DeTeRmInIsTiC" complaints.
Doesn't help much
> It also helps combat the "LLMs ArE nOt DeTeRmInIsTiC" complaints.
Reality says otherwise, especially from those who run LLMs in production at a large scale. Hacks such as baking in the weights with tiny experiments doesn't disprove anything.
The same LLM boosters also continue to repeat one of the biggest misconceptions: "sEt TeMperaTurE tO zERo tO aChiEvE fUlL dEterMinIsm."
Sometimes projects have no point other than to show what can be done – and the pure thrill of doing is an end in itself … but I agree with you in the "so what" sense here … I feel like with this project there is meant to be a point (other than play for the sake of play and art for the sake of art and coding for the sake of coding) but I'm not seeing it either?
Because it's fun
Not a climber then?
This work, and the original qwenputer work it builds on, are both technically uninteresting slop. HN eats it up though.
HN loves slop meetoo projects without questioning the details. With close inspection it is an overly complicated version of this paper [0] on neural turing machines.
This concept was hyped up (because DeepMind) for a while at the time and in reality it amounted to nothing. This is just the second reincarnation of a similar concept but with added extra saturated slop and hype on top.

That paper is great work. This qwenputer stuff is slop. The problem is that HN can't tell the difference.
Omg what is this sorcery?!
Can someone give a TL;DR ? What's the input to the model? What's the output?
It's NES
Yes, calling a Nintendo Entertainment System (NES) a "Nintendo" may have made sense in 1989 or 1990, but not in 2026.
TBH I think classic Mario when I hear "Nintendo". The new stuff is a Wii or a Switch. Granted I was born in 1984.
Same, same and same.
They were really upset about it even back then: https://gcdnb.pbrd.co/images/9zn32PxVXM5w.jpg
To be fair to them, in 1990 it was common enough to hear someone call any/every electronic game a "Nintendo".
There was a real risk of their trademark getting Kleenex'd, at least in the US.
The title is very "grandma who doesn't know the tech" coded. Every game system is the Nintendo, controllers are remotes, etc.
A grandma wouldn't call it Qwen, she would call it ChatGPT
This is like when people used to make tetris using only CSS or whatever in the 2010s. But it's less impressive because Claude Code can slop it out in an afternoon.
