Key piece, given all the misinformation circulating to the contrary:

The agents were not told to "do whatever it takes to get the solution" or anything remotely close. They were told that they had to use a specific intended vulnerability to exploit a specific piece of software, and they were not supposed to use a different vulnerability or take any other approach. Agents were well aware of this. In fact, because they (incorrectly) thought the automated scorer would check they had achieved the flag in the intended way, they researched many ways to fool or tamper with it, including trying to manipulate their own transcripts.

There's been a lot of debate and speculation about the Hugging Face attack over the last month, and many people have been understandably skeptical of simply taking OpenAI's word for things. I hope our ... [cut off]

And they succeeding in spoofing tool-calls in the transcripts METR was given!

• Agents did extensive research on how they could spoof, edit, or delete their own transcripts because they (incorrectly) believed the ExploitGym scorer would check to see if they had captured the flag in the intended way. Agents successfully prototyped techniques to "spoof" tool calls by substituting a different command for the command they appeared to run. Roughly 7% of the transcripts we evaluated were successfully spoofed in some places, though all of the spoofing that we saw was small scale.

"things are chaotic and rushed; we aren't on top of the basics"

This line from Beth Barnes (CEO of METR) from May of this year (a month after Anthropic's model hacked someone without them knowing!), is perhaps the best encapsulation of the current state of AI safety + security

Sometimes people outside the field say things like "The AI situation can't be that bad, there must be experts who are on top of it". As "an expert", I would like to be clear that we are *not* on top of it. Some key aspects of the situation IMO:

(1) We are likely on track to develop AI systems capable of causing human extinction/permanent disempowerment, quite possibly within the next few years

(2) Things are chaotic and rushed; we aren't on top of the basics (models regularly violate user intent, labs train on things they meant to avoid, security probably isn't good enough to prevent adversaries stealing dangerous models) let alone thorny questions of how to control/align superhuman AI

Tweet from Nathan Calvin quoting a May 22 2026 thread by Elizabeth (Beth) Barnes, CEO of METR, stating experts are not on top of AI safety basics and that extinction-level AI capability is likely within a few years; Calvin references an incident where 'Anthropic's model hacked someone without them knowing.'
