If the information isn't there why would they need safeguards against it?
I've played with smaller unrestricted local models and they will tell you how to make a bomb with easily available items as well as where to source them. I don't doubt that these >1000B frontier models have better information.
>If the information isn't there why would they need safeguards against it?
If the information is in the corpus then it's also in the public Internet and/or in books. The safeguards are there not because the model knows non-public information, but because it's a bad look for the model to dispense that information.

Making a chemical explosive is trivial compared to making a nuclear weapon.
