Fable 5 is back on the menu

Anthropic is restoring Claude Fable 5 after the US Department of Commerce lifted export controls on Fable 5 and Mythos 5.

Access to Fable 5 will start returning globally on Claude from Wednesday.

Anthropic also plans to bring it back on AWS, Google Cloud and Microsoft Foundry, though there is no firm date yet.

The models were restricted in early June over jailbreak concerns, blocking access for foreign nationals, including some enterprise users and Anthropic employees outside the US.

Anthropic says it has now trained a stronger safety system to block the jailbreak method flagged by Amazon researchers.

The company says that specific technique is now blocked in more than 99% of cases. Blocked Fable 5 requests will be sent to Opus 4.8 instead.

The company also plans to work more closely with the US government before future model launches, including early testing for models linked to national security risks.

Anthropic is also working with Amazon, Microsoft, Google and others on a shared framework for judging AI jailbreak risks.

Anthropic says no AI model can be made fully jailbreak-proof, but no universal jailbreak for Fable 5 has been found so far.

Basically, Claude is coming back, but now with more guardrails, more government involvement, and the kind of launch paperwork that could legally qualify as cardio.
