Anthropic launched Claude Mythos 5 and Claude Fable 5, frontier model updates emphasizing enhanced reasoning and safety tooling.
Mythos 5 targets complex analytical workloads while Fable 5 focuses on narrative and creative applications with stricter content guardrails.
Anthropic said both models incorporate lessons from Opus 4.8’s built-in bouncer safety layer.
Enterprise customers can access the models through Anthropic’s API and Claude consumer subscriptions.
