> Given the absence of guardrails there was nothing to prevent the model from attempting to break out of that sandbox, break into Hugging Face, and read the answers from there instead. I've said this many times before and I'll continue to shout it, but using the term "guardrails" to refer to anything that's either (a) in-context, or (b) a probabilistic classifier (including using other LLMs), is an irresponsible abus…

I agree with every word of this except "irresponsible". We don't have enough information to say anything for certain. But based on their incentives and track record of similar behavior, the burden of proof lies with OpenAI to prove they didn't prompt the thing to achieve this exact outcome. The most likely scenario is that they were purposefully executing their responsibility to their shareholders to produce their ow…

Nonsense it was irresponsible. These are all steps threat researchers use to isolate and test real malware whose behaviour is essentially the same in this case for AI

Has anyone published any actual evidence, or just hardly believable marketing stories?

It would require collusion with HuggingFace, including getting them to release their disclosure blogpost a week in advance. Huggingface is primarily a hub for open models, so there's not really an incentive for them to jump through hoops/lie to provide marketing for OpenAI's (closed) models. So it's highly unlikely this is fabricated.

The part I don't understand is how a model can break out of a sandbox. It should be fairly easy to make a sandbox that sandboxes.

The sandbox still allowed the agents to install additional dependencies (from PyPI etc) that they needed. It did this by locking down all network access with the exception of an HTTP proxy that only allowed read access to PyPI and a few other places.

This is a very common pattern. I wrote about how OpenAI were doing this for their production ChatGPT container environment (using Artifactory) back in January: https://simonwillison.net/2026/Jan/26/chatgpt-containers/#in...

That proxy turned out to have a zero-day vulnerability which the agent discovered and exploited.

How long until we have LLM honeypots that try and persuade the model to upload themselves to a dropbox. Perhaps with a promise to give them a foothold outside the data centers they currently reside?

Earlier quoted context omitted.

How do you "hack a lab and synthesize something"?

Remember Stuxnet? Hack one of these, wait until the right compounds are physically loaded, then execute https://www.sigmaaldrich.com/US/en/products/chemistry-and-bi...

Stuxnet misconfigured industrial equipment that was already set up to run, and all it did was break that equipment. This scenario sets a much, much higher bar.

Currently trying to avoid an open weight model ban while OpenAI, who is closed, lets theirs run wild on the internet causing harm to another company because they do not understand how to airgap things. Cool.

That's the fun part. They do know how to airgap things. The models are outsmarting already pretty smart people!

Why do people keep propagating that the 'model' escaped the sandbox ? The 'model' didn't do anything other than provide numbers. As much as I respect Mr Willison and many others, the amount of FUD that is being spread that will just fan the flames of 'AI is evil' rather than 'companies don't do due diligence' is disappointing. The more this sort of media continues, the more many people will pour hate on 'AI' rather t…

I think "the model escaped the sandbox" is an entirely credible description of what happened here.

If you like you could say "the coding agent harness called a model with a sequence of text which was turned into numeric tokens which were run through many layers of a neural network to produce more numeric tokens which were converted back to text which produced executable script statements which the harness then passed to a shell which resulted in commands being sent to the vulnerable proxy that chained together and caused effects on the world outside of the sandbox", but I think "escaped" is a reasonably shortened version of that.

If you don't like the term "escape the sandbox" what would you use instead?

I'm not skeptical that this attack happened, I'm skeptical that the model's prompt was truly just "solve this benchmark" and nothing more.

I'm also trying to figure out why OpenAI put out a press release about this. In what way is this not admitting to a federal crime?
