Anthropic redeploys Claude Fable 5 globally starting July 1

Anthropic is redeploying Claude Fable 5 and Mythos 5 globally starting July 1 following a US government decision. Restrictions were previously imposed after an Amazon report revealed a method to bypass Fable's cybersecurity safeguards. Anthropic has since implemented a new safety classifier blocking this method in over 99% of cases. The model remains within weekly limits until July 7, transitioning to API access thereafter. The company is also developing a common standard for evaluating AI jailbreaks.
