Third, while we had tested and validated this sandbox, the agents were able to chain together previously unknown vulnerabilities (“0-days”) in the package management service exposed within the sandbox to bypass restrictions
How were they supposed to know about "previously unknown vulnerabilities"?> This is pretty clearly a marketing stunt by OpenAI, otherwise the story just doesn't add up
The "it's just a marketing stunt" allegations never added up, to me.
I've been seeing such claims since GPT-2, where people were laughing at them for daring to practice how to secure a model before it got dangerous, generally by eliding the word "before" in that sentence. Because there's tests other than what the big companies use, we've been able to see for ourselves the rapid improvements at least approximately match what the companies themselves claim with the models they do actually release; and now this unreleased model is able to automate felonies when asked to do so, while the rest of us use the actually-released models to assist in finding bugs and security issues in our own code.
Even without that, HuggingFace stated they reported this incident to the FBI before OpenAI knew it was their systems which did it.
