I used to work at a "frontier lab" before they were called such thing.
We had three levels of lab isolation, one was basically a thin proxy to the internet. You were in a DMZ and that was about it.
The next level was semi isolated, you were allowed some access to the internal network, but it was heavily firewalled, and you only had access to a limited number of internal services, and not internet.
the last one was no internet no internal. You could, if you filled in a bunch of requests have access to the internal repo and build system.
At no point did you ever have a through proxy to the public internet. you had access to internal mirrors, and if you wanted a library, that had to be ported to the thirdparty repo.
What openAI did was either deliberate or fucking shoddy.
All of this is fucking noise. Worse still I have a strong suspicion that it was a stupid mistake borne of naivety, which is now being used as a marketing ploy. Frankly I think openAI are purdue pharma of tech. They are going to break so much stuff and be protected from the consequences by an openly corrupt legal system. because they are "winning the AI race"
