“But it appears 1 or more organizations have successfully jail-broken Fable 5”

This is hardly true or it’s true of all frontier models and this was only magnified by Fables capabilities. It’s that you could hand Fable 5 vulnerable code, ask it to fix it, return patch plus test cases proving the fix and exploit relevant detail falls out as a byproduct of legitimate secure code review work.

I challenge anyone to provide a fix for this “exploit” without compromising Fable’s ability to patch unsecure code.
