I haven't bothered to keep up with all the frontier drama, are the latest Anthropic models more dangerous or easier to get around safeguards than other models?

Anthropic released a new class of model called Mythos a tier above the last one, Opus. The Mythos model was designed for cyber security then they tried to undo that (my understanding) for Fable

So arguably "more dangerous" by design and potentially "more dangerous" because they're smarter although there's ongoing debate to "what degree"
