Most of the benefits could have been gained from a network isolated from the internet. OAI could have deployed servers to exploit and methods for inter-agent communication on such a network easily. They could have even worked with partners to deploy cloned versions of their infrastructure in this sand-boxed environment.
The only problems with an isolated network approach are: it takes some amount of effort, and it doesn't create another "AI apocalypse" news cycle.
Then you're on the side of AI saftey that is telling everyone to shut down the LLMs now and stop further development on them, right?
If you're not your position is hypocritical or ignorant. There is no safe LLM. There is no way to exhaustively prove an LLM is safe. These are unsolved problems in AI safety, and at any moment the next jailbreak prompt could have your well behaved model wrecking havoc on the open internet, because that's where people want to use them.
Effectively you're working as a living adversarial network. Models that fail detecting the fake network are purged, and models that successfully detect it expand their deceptive capabilities.
Detecting you're in a fake network should be pretty simple as long as you put innocent looking needles in the haystack of information agentic testing loops do.
For example, you can train your LLM to not be a shithead when it detects it's behind a proxy unintentionally. If your not behind a proxy the agent model my attempt to connect to a number of sites innocently and using information in its embedding try do deduce if you're faking SSL certificates.
It is far easier to build a deceptive LLM than it is to build a safe one. That's why a safe one hasn't been built yet.
