Claude Fable 5.2 and Mythos 5.2

Anthropic released Claude Fable 5.2 and Claude Mythos 5.2, saying both improve on coding, reasoning and vision, with output up to 30% faster than version 5.1.

Why it matters: Anthropic gives one underlying model different safeguards and access terms, so general users and cyber-security or biomedical research institutions get clearly different task permissions.
