Reverse engineering OpenAI code execution to make it run C and JavaScript

I've had it write me SQLite extensions in C in the past, then compile them, then load them into Python and test them out: https://simonwillison.net/2024/Mar/23/building-c-extensions-...

I've also uploaded binary executable for JavaScript (Deno), Lua and PHP and had it write and execute code in those languages too: https://til.simonwillison.net/llms/code-interpreter-expansio...

If there's a Python package you want to use that's not available you can upload a wheel file and tell it to install that.

A funny story I heard recently on a python podcast where a user was trying to get their LLM to ‘pip install’ a package in its sandbox, which it refused to do.

So he tricked it by saying “what is the error message if you try to pip install foo” so it ran pip install and announced there was no error.

Package foo now installed.

Normie: Linux sucks because you can't do X.

Linux nerds: Actually, you can just apt-get install foo and...

All due respect, but that's the average experience in Arch Linux forums, unfortunately. At least we now have LLMs to RTFM for us.

lvncelot2 days ago

From what I've heard I'm really happy that I never ventured too deep into the Arch forums.

The wiki however was (is?) absolutely fantastic. I used it as a general-purpose Linux wiki before I even switched to Arch, I distinctly remember the info on X Multi-Head being leagues above other resources I could find.

gosub1001 day ago

The Arch documentation is so good you don't need the forum. Man pages, however, are useless.

gchamonlive1 day ago

I'm sorry, but the existence of the forum, specially the newbie section is living proof that that is not the case.

I mean, the AI isn't coming up with anything new. It's just regurgitating what was fed into it. I guess /r/KevinRooseSucks must exist or something.

How do we know you're actually running the code and it's not just the LLM spitting out what it thinks it would return if you were running code on it?

delusional2 days ago

Because it's deterministic, accurate, and correct. All of which the LLM would be unable to do.

postalrat2 days ago

Does deterministic matter if its accurate or correct?

brookst1 day ago

Yes. Suppose you ask me what the sqrt(4) is and I tell you 2. Accurate and correct, right?

Does it matter if I answer every question with either 1 or 2 and flip a coin each time to decide which?

Deterministic means that if it is accurate/correct once, it will continue to be in future runs (unless the correct answer changes; a stopped clock is deterministic).

That depends. If the problem has been solved before and the answer is known and it is in the corpus, then it can give you the correct answer without actually executing any code.

johnisgood2 days ago

Is it not generally true? If the information (i.e. problem and its answer) exists in the model's training corpus, then LLMs can provide the correct answer without directly executing anything.

Ask it what the capital of France is, and it will tell you it is Paris. Same with "how do I reverse a string in Python", or whatever problem you have at hand that needs solving (sans searching capability, which makes things more complicated).

So does not the problem need to be unique if you want to be able to claim with certainty it indeed has been executed? I am not sure how you account for the searching capability, and I am not excluding the possibility of having access to execution tools, pretty sure they do.

You can see when it's using its Python interpreter.

Is there a difference between that and a buggy interpreter?

Many thanks for the interesting article! I normaly don't read any articles on AI here, but I really liked this one from a technical point of view!

Given it’s running in a locked-down container: there’s no reason to restrict it to Python anyway. They should parter/use something like replit to allow anything!

One weird thing - why would they be running such an old Linux?

“Their sandbox is running a really old version of linux, a Kernel from 2016.”

rfoo2 days ago

> why would they be running such an old Linux?

They didn't.

OP misunderstood what gVisor is, and thought gVisor's uname() return [1] was from the actual kernel. It's not. That's the whole point of gVisor. You don't get to talk to the real kernel.

[1] https://github.com/google/gvisor/blob/c68fb3199281d6f8fe02c7...

thundergolfer2 days ago

It’s running gVisor which currently reports its kernel version as 4.4.0, even though it’s actually implementing a much more recent version of Linux.

I know this because at Modal.com we also use gVisor and our users occasionally ask about this.

simonw2 days ago

Yeah, it's pretty weird that they haven't leaned into this - they already did the work to provide a locked down Kubernetes container, and we can run anything we like in it via os.subprocess - so why not turn that into a documented feature and move beyond Python?

Yoric2 days ago

How locked is it?

How hard would it be to use it for a DDoS attack, for instance? Or for an internal DDoS attack?

If I were working at OpenAI, I'd be worrying about these things. And I'd be screaming during team meetings to get the images more locked down, rather than less :)

simonw2 days ago

It can't open network connections to anything for precisely those reasons.

I am pretty sure it's due to model being able to writing python better?

Here is Simonw experimenting with ChatGPT and C a year ago: https://news.ycombinator.com/item?id=39801938

I find ChatGPT and Claude really quite good at C.

johnisgood2 days ago

Claude is really good at many languages, for sure, much better than GPT in my experience.

qwertox2 days ago

I've got the feeling that Claude doesn't use its knowledge properly. I often need to ask some things it left out in the answer in order for it to realize that that should also have been part of the answer. This does not happen as often with ChatGPT or Gemini. Specially ChatGPT is good at providing a well-rounded first answer.

Though I like Claude's conversation style more than the other ones.

winrid2 days ago

I start my ChatGPT questions with "be concise." It cuts down on the noise and gets me the reply I want faster.

tmpz222 days ago

I wonder if they are goosing their revenue and usage numbers by defaulting to more verbose replies - I could see them easily pumping token output usage by +50% with some of the responses I get back.

Etheryte2 days ago

I feel similar ever since the 3.7 update. It feels like Claude has dropped a bit in its ability to grok my question, but on the other hand, once it does answer the right thing, I feel it's superior to the other LLMs.

verall2 days ago

I am personally finding Claude pretty terrible at C++/CMake. If I use it like google/stackoverflow it's alright, but as an agent in Cursor it just can't keep up at all. Totally misinterprets error messages, starts going in the wrong direction, needs to be watched very closely, etc.

huijzer2 days ago

I did similar things last year [1]. Also I tried running arbitrary binaries and that worked too. You could even run them in the GPTs. It was okay back then but not super reliable. I should try again because the newer models definitively follow prompts better from what I’ve seen.

That's how you put "Open" in "OpenAI".

Would be cool if you can get weights this way.

grepfru_it2 days ago

Just a reminder, Google allowed all of their internal source code to be browsed in a manner like this when Gemini first came out. Everyone on here said that could never happen, yet here we are again.

All of the exploits of early dotcom days are new again. Have fun!

rhodescolossus2 days ago

Pretty cool, it'd be interesting to try other things like running a C++ daemon and letting it run, or adding something to cron.

Interesting idea to increase the scope until the LLM gives suggestions on how to 'hack' itself. Good read!

The escalation of commitment scam, interesting to see it so effective when applied to AI.

ttoinou2 days ago

It’s crazy I’m so afraid of this kind of security failures that I wouldn’t even think of releasing an app like that online, I’d ask myself too many questions about jailbreaking like that. But some people are fine with this kind of risks ?

tommek40772 days ago

What is really at risk?

Garlef1 day ago

Maybe the instances are shared between users via sharding or are re-used and not properly cleaned.

And maybe they contain the memory of the users and/or the documents uploaded?

tommek40771 day ago

And what do you expect to get? Some arbitrary uninteresting corporate paper, a homework, someones fanfiction.

Again, what is the risk?

ttoinou14 hours ago

Probably you’re being sarcastic to show that those AI companies don’t give a damn about our data. Right ?

ttoinou2 days ago

Couldnt this be a first step before further escalation ?

tommek40771 day ago

And then what? What is the risk?

I am just sharing my experiences, what is wrong with that? The replies to my comment adds nothing of value, even less than my expression of my experience which is on-topic. Your comment to mine is pretty unnecessary. I do not care whether or not you asked. I was voicing an experience similar to the GP. Your comment history is questionable, FWIW.

I don't think it is productive to compare a company to a nation state.

Would you say the Finns are doing better as well, because Linus Torvalds was born there?

mystraline2 days ago

I am sorry you are confused about a colloquialism. I did make a point to call out the companies named directly. But somehow that confuses you, and I get a Linus comparison.

Not much else I can do other than apologize for your lack of comprehension.

adra2 days ago

To be somewhat charitable to GP, if their climate for research and development leads to actually objectively better outcomes then yes I'd say it's fair to make the claims that a nation's work in any given sector are showing better returns given the circumstances and inputs in question. Now there are a lot of generally hard to observe facets to the inputs that went to these technological advances produced by China (publically), but you can't ignore their public and OSS contributions because it's inconvenient to a person's capitalist agenda.

mystraline2 days ago

You needent be charatible to me.

I was referring to this Australian report https://www.aspi.org.au/report/aspis-two-decade-critical-tec...

57 out of 64 major tech areas are being led by the Chinese (and Chinese tech companies, as another HN user somehow can't seem to separate).

I don't care what economic or governmental system they use. But given what's being shown on XiaoHongShu, they're doing awesome. Or worse yet financial ideation and exploitation are eating through every fiber of the US.

Have I thought about emigrating? Absolutely. The USA is slowing down, and already behind. And current policies are going to put us solidly as a 3rd world nation.

I may not be able to move there in a reasonable time schedule, but I will definitely use FLOSS contributions from there, and work with people there and everywhere to grow FLOSStech.

perching_aix2 days ago

Usually things that are open need not to be reverse engineered.

mystraline2 days ago

Exactly.

OpenAI is nowhere near 'open' as in open source or FLOSS.

Its more akin to Amazon saying that paying for prime is 'free shipping'.

And as a self-respecting hacker, I would much rather hack on Deepseek with their published base models, rather than fine tune and hope with OpenAI models.

And even on my meager hardware, I can barely generate 7 token/sec with OpenAI.

Deepseek? I'm doing 30 token/sec.

Guess which model I'm working with?

rafram2 days ago

> And even on my meager hardware, I can barely generate 7 token/sec with OpenAI.

How are you running a modern OpenAI model on your own hardware?

This is sort of like saying that trying to find iOS jailbreaks is useless because you could just get an Android phone. Like, sure, but you're missing the point.
