Anthropic brings Claude Fable 5 to the public — with guardrails doing much of the work
Anthropic has announced Claude Fable 5 as a public-facing version of its Mythos-class model, paired with a safety design that routes some higher-risk requests elsewhere. The release matters not just because of the model claims, but because it shows where frontier AI deployment is heading: broader access, narrower permissions, and far more explicit controls.
