screenshot of the aftermath of our #Pwn2Own Safari chain that @_niklasb @qwertyoruiopz and I did. This was a lot of fun and I cannot thank these two enough for working together on this :)

I'm sorry, but you don't get to have it both ways. I fully empathize with the human grace aspect here, and the amount of work put in by the OAI security team and the enormity and novelty of the challenges they face, but your own leadership (and every frontier lab) has been sounding the alarm for too long about the existential threat to humanity and societal order your own technology poses.
You don't get to set the stakes that high, willingly *choose* to train your models to perform offensive cyber, *repeatedly* fail your basic responsibility in spectacular ways, and throw your hands up and say "whoops, it happens!" To be clear, I truly understand that mistakes can and do happen (we're only human) and sometimes the unexpected can occur. But these are no longer exceptional, isolated cases. It's become a pattern of systematic failure, and from the outside, the only explanation is incompetence, organizational failure, or a lack of caring either at the leadership or employee level.
If you're telling us that the latter part is wrong, that you have the best employees in the world and they care a lot about solving this, then I believe you. But the problem is still somewhere else, and you still don't get to have it both ways.

At this point it’s absurd and embarrassing. How many hundreds of billions in funding do you need to hire a security team that understands basic sandboxing and network isolation?
Thanks DFsec!!
