Basic safeguards are all that's required, and they've been there in every usable model since GPT-2, including Chinese models that are supposedly "unsafe".
Or are we saying that some lunatics will start training their own models, spin up a GPU cluster, run some abliteration workflow, or learn how to jailbreak?
That would be a very dedicated person. And dedicated person doesn't need an LLM. So where are they?
Am I saying that guardrails don't work? No, they probably stop a lot of insane people trying insane things. But you don't need Fable-level guardrails to do that. You probably don't even need to do anything during pretraining, or RL, or classification to make sure model refuses to compy with "hack me a bank" or "make me a chemical weapon".
All models will automatically have guardrails just as a result of training on data that gives them intelligence. You have to actually train it to be malicious to produce something what Dario calls "insufficient guardrails".
No guardrail is going to stop a determined person with sufficient intelligence. It only has to stop ones with insufficient one, and even basic guardrail that are just by-product of training is going to achieve that.
