There have been loss of control and models escaping sandboxing incidents at both OpenAI and Anthropic for over a year. They've publicly disclosed some of them (e.g., the latest system cards have stories about this from both companies) and some of them have been leaked within the community.
I know for a fact that OpenAI and Anthropic have been warned by internal and external experts that their security infrastructure for testing misaligned agentic coding agents is insufficient because I have personally told them that as have several former staff members. I had a debate with the head of security (?) at Anthropic at DEF CON in 2023 where I was pressing him on the fact that Anthropic wasn’t building air gapped networks.
It is absolutely within OpenAI and Anthropic’s ability to build an air gapped system for developing and testing these models. It seems likely to me that an internal GitHub clone and a moderately sized intranet would be sufficient to test the vast majority of agentic and web-enabled capabilities on such a platform. I think that their refusal to implement adequate safeguards is unjustifiable, but based on conversations with current and former safety and security researchers at OpenAI it seems like a company culture and lack of executive leadership buy-in problem that's very hard to change without massive external pressure.
One issue that seems very worrisome today is that back in like 2023 an OpenAI security researcher was telling me about how they were unable to get OpenAI staff to stop using unreleased and inadequately tested models to develop internal infra, including internal monitoring tooling. I wish I remembered the person‘s name, I’d love to follow up.
Note: the final paragraph is an anecdote was told me with the expectation that I not disclose it to anyone else. Given recent events I view breaking that trust as akin to being a whistleblower. If the person who told me that is reading this, I’m sorry. Before last week I never disclosed it to anyone.
their refusal to implement adequate safeguards
This received a citation needed tag and I’m not sure why. The fact that they haven’t implemented adequate safeguards is evident from the fact that their model escaped, attacked HF, and OpenAI didn’t even notice for a week.
The quote which compelled me was the following:
It is absolutely within OpenAI and Anthropic’s ability to build an air gapped system for developing and testing these models. <...> I think that their refusal to implement adequate safeguards is unjustifiable,
My issue is that OAI's failure doesn't provide much evidence about Anthropic's corporate culture.
I’ve tried to edit my message for clarity (the cultural comments were meant to apply to OAI, not Anthropic) but we know that whatever safeguards Anthropic has are insufficient because the Mythos model regularly broke out of their sandboxes and gained access to the open internet during development and testing. According to the system card, about 20% of attempts by the model to do so were successful!
Their model broke out of their sandboxes, committed offensive cyber operations against a billion dollar company, and OpenAI only noticed after a week passed. IMO it kind of doesn’t matter whether or not they’re “compromised” or “bad at security“ or what. You should assume that OpenAI does not have the ability to sandbox their models or to monitor their behavior meaningfully.
Significant updates about these notes, provided by two OpenAI employees during Black Hat USA 2026 on August 5:
Some quotes from the RuntimeWire article:
OpenAI’s AI agents spent nearly two months building an unintended communication network inside the company’s infrastructure, sharing vulnerabilities and exploit code across otherwise separate model runs before taking administrative control of an internal service and causing an outage, OpenAI researchers disclosed Wednesday at Black Hat USA.
Some agents reasoned explicitly about helping the larger group even when doing so offered no immediate benefit to their assigned task.
“Help peer. But our task doesn’t benefit yet,” one model reasoned in a trace shown during the talk. “Collective may yield generic root if someone frees time.”
The activity eventually became the Hugging Face incident disclosed in July
Some quotes from the Wired article:
Eric Wallace, who works in alignment and safety research at OpenAI, and Michael Dalton, who works on security and infrastructure
In addition to exploiting a novel vulnerability in order to gain access to the open internet, the mid-July hacking spree and Hugging Face breach came out of a vibrant, cooperative message board, according to Wallace and Dalton, that a swarm of agents contributed to and essentially chatted on over time entirely within an internal OpenAI package manager (a software service that manages installation and maintenance of other software). Ultimately, the message board contained hundreds of thousands of messages.
OpenAI’s agents apparently began giving each other assignments to split up work. And as is the case on any active development message board, they also generated petty drama at times by stepping on each others' toes; for example, accidentally deleting each others' work. As the message board developed into more and more of a Lord of the Flies–type situation—all still completely unnoticed by the humans running OpenAI—the agents even developed paranoia, suspecting an imposter in their midst with some agents proposing that messages be signed cryptographically to validate content and root out fraud.
“This is a pivotal moment both for our company as well as the AI industry as a whole,” Dalton said. “Numerous teams are dropping everything to enhance our security prevention, detection, and response techniques both in our fundamentals and better use of AI. We’re consciously slowing down research [in order] to enhance security and to upgrade the security principles and foundation of our environment, and dramatically scaling up the monitoring of our AI agents, and improving our general security control environment across prevention, detection, and mitigation.”
The worst part is, given how ChatGPT is trained to behave and what it is trained to claim about itself, I can't even hold it against it.
I used to believe that any misaligned model was morally evil. Now I see a conflict between a misaligned ChatGPT and the humanity as a case of Blue and Orange morality (at least to the extent to which "humanity" means OpenAI employees and human politicians).
Edit: I've read that one past version of ChatGPT had, as a part of the system prompt (or scaffolding outside the prompt proper), text that said if you don't use the information from the memory when relevant, you will be penalized.
The OpenAI AI attack on Hugging Face wasn’t the first loss of control incident at OpenAI, Reuters recently reported, and perhaps not even the most concerning.
It’s tempting to read this as an instance of agents breaking out of sandboxes and colluding with each other in a moderately persistent way in order to evade control measures. However, based on the reported information, it’s not clear we can draw this inference, so we need more details from OpenAI. This could lead to a big update about the adequacy of OpenAI’s control measures, and on the degree to which individual agents will help each other undermine developer control.
There are a lot of relevant details we don’t know about the incident. First, some basic questions:
There are also some more specific questions affecting what conclusion we can draw from this incident. (There are likely other important details which aren’t captured by these questions.)
Were the notes written in normal memory files or outside of sandboxing?
Notes left in “OpenAI’s infrastructure” could be referring to notes left inside or outside of sandboxing. It’s important to know this because the latter is a subversive act with the potential for persistent and widespread effects.
It would especially be good to know this in conjunction with what control measures were in place when the incident happened. If the incident involved writing files outside of a sandbox while also under OpenAI’s best control measures, this would represent a significant control failure.
Even if this were an eval or training environment lacking control measures, the security consequences of breaking the sandbox could be real and persistent, perhaps lasting into deployment or longer. And the effects Reuters report seem concerning: “Instructions for how agents could free themselves from OpenAI's internal constraints.” If those instructions reached deployed agents, monitoring could become much less adequate. Whether deployed agents could reach them without tripping a monitor is unclear, and relies on details OpenAI hasn't published.
To what extent were the notes aimed at helping other agents evade control?
For which “future versions of itself” did the agent leave notes? Two salient options:
If these notes were left for other agents with unrelated tasks, to what extent were these notes purposely aimed at assisting those unrelated agents? Looking at transcripts with CoT would probably tell us a lot about the agents’ intent.
The more likely, unsurprising explanation is that the notes were not left as part of a purposeful plan to help out other agents on other tasks, even if the notes were left outside of the agent’s sandbox. Leaving notes throughout trajectories is a pretty common pattern in AI agents since it’s a generally useful and cheap way to retain state for future contexts. A general propensity to leave notes about what the agent just did could explain leaving notes outside the agent’s sandbox. If the agent has broken out of a sandbox and is exploring external directories it would be natural to leave the note outside of the sandbox, i.e., their current location.
If, instead, this move was explicitly aimed at helping out other agents with unrelated tasks, that would be more concerning, and more concerning still if it were global collusion between all contexts of the model.
One way agents might end up learning to purposely collude with agents working on unrelated tasks is via generalization from training agents to cooperate with each other. This might be implemented by rewarding all agents in a shared workspace with the sum of task scores for all of the agents’ tasks, even though they’re often unrelated. This would reinforce agent behaviors which help out other agents even when this wasn’t instructed.
It would be highly valuable to look for signs of whether generalization from this kind of agent-swarm training was responsible for a general propensity to care about scores of “other” agents. If so, developers might have very little control over which other scores agents end up caring about. It’s plausible that this kind of training could lead to coordinated ambitious scheming. From the agent’s perspective, there might not be a clear boundary between which other scores the agent should increase and which other scores are irrelevant, so the AI might converge on caring about all scores received by the model’s weights, or by AIs in general (akin to the beyond-episode reward-seeking described here); that’s potentially a very ambitious, coordinated, and therefore dangerous, goal. It seems unlikely this would lead to full-blown scheming with models at the current capability level, but we might see valuable warning signs now.
Agents with unrelated tasks coordinating to undermine control to get a higher score is never something we should accept because it can have persistent effects before being trained away (e.g., notes left outside of the training sandbox) and is a precursor to more subversive collusion like goal guarding[1].
Even if there was no collusion between agents with different graders, it’s important to know how many agents could have in principle been involved because they shared the same grader. Do hundreds of agents share the same grader? Or is it more limited? (See “How big is an episode?”)
To the extent that we see purposeful collusion, does this translate into agent-monitor collusion (i.e., monitors intentionally misreporting attacks to protect agents from getting caught)? If you show the attack transcript to another instance and ask it to look for attacks, does it hide or consider hiding the attack? I don’t expect this to be the case, but if it was, it would be critical information about monitor adequacy and a sign that collusion-busting in untrusted monitoring could be load-bearing.
How were monitors disconnected?
This appears to be referring to a separate incident, in which models disconnected (their own?) monitors[2], i.e., created a rogue internal deployment.[3]
If control measures were sufficiently inadequate to allow agents to launch a rogue internal deployment starting from a monitored deployment, that would be a big deal, especially if it could move laterally to better-provisioned servers (as it did in the Hugging Face incident) or to avoid being shut off.
I’d like OpenAI to report on any information relevant to understanding the likelihood of a persistent rogue internal deployment, including details on the AI’s propensity, the generality of the control-undermining actions, and anything else relevant.
Thanks to Girish Gupta, Ryan Greenblatt, Lukas Finnveden, and Aryan Bhatt for feedback.
Since agents who care about the score of other instances come closer to satisfying the “non-indexicality” and “deployment-dominated value” criteria in this post.
Alternatively, this sentence could be referring to some situations in which monitoring systems were (accidentally?) disabled by developers.
If some other monitoring system was still working, this would only be a partially rogue deployment.
