Anthropic launches Claude Fable 5, its most powerful AI model yet, balancing advanced capabilities with strict safety safeguards and restricted high-risk uses.

Anthropic has released a full version of its cybersecurity-centric Claude Mythos model—along with a safer version for the general public.

It says new safeguards make it possible to release a Mythos-class model it previously said was too risky to make public.

Fable 5 is the first Anthropic Mythos model released for public use.
