You don't have the strong cybersecurity model. That is not Fable. It never was, even at release.

The cybersecurity model is Mythos, which was never made publicly available. It is only available to a list of US government approved companies.

> They said it wouldn't be usable for offensive purposes

No, they said Fable would refuse for cybersecurity and offensive purposes. You are conflating Fable with Mythos.

They're very similar models though, just with different safeguards and restrictions in placae around particular use cases.

I guess the underlying issue is that there is this model that is very capable, but it's being hobbled because of a fear of abuse. It may well be justified, but for a legitimate user any restriction just makes it a worse product and after all the puffery around how good it is (and some practical experience of how good it is) it's a pretty shit experience. "Here's our best model, no you can't really use it".

Fable adds guard rails like cyber refusals to mythos. Mythos is the starting point for fable. Same model family.
