> Claude Fable is back!
> 
> Anthropic has lifted restrictions on Claude Fable 5 and Mythos 5 after a decision by the US government.
> 
> Fable will be available to Claude users again starting today.
> 
> Until July 7, the model is included in weekly limits. After that, access will move to API.
> 
> The restriction started after an Amazon report: researchers found a way to bypass Fable’s safeguards in cybersecurity tasks.
> 
> Anthropic says the bypass did not unlock Mythos-level capabilities. The company has already added a new safety classifier that blocks this method in more than 99% of cases.
> 
> Anthropic is also preparing a common standard for evaluating AI jailbreaks.
