Anthropic announced on Tuesday that its Claude Fable 5 model could once again be released to the public following an export control directive that had forced it offline on June 12. The company stated that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5, allowing for the restoration of access to the model.
Why was the model temporarily restricted?
The restriction, which took effect in 2026, stemmed from an export control directive. Fable 5 was part of the Mythos class of Anthropic AI models, announced in April as a cybersecurity tool and potentially a super-weapon in the hands of hackers seeking to cause harm. The Mythos model family was initially only available to a select group of partner organizations. Fable 5 was intended to be a consumer-ready version of Mythos, with some of its more concerning capabilities toned down. However, about three days after it was released, Anthropic announced that it had to be taken offline after the Trump Administration issued its export controls, citing reports that Fable 5’s safeguards could be easily bypassed.
Anthropic has been in negotiations with the Trump Administration ever since. Over the past week or so, those negotiations have reportedly improved, which culminated in the lifting of the controls on Tuesday night.
How does this affect AI model distribution?
The resolution of this case highlights the intersection between commercial AI development and trade policy. Anthropic must navigate vetting processes for its releases.
What is the status of the Claude model family?
Anthropic maintains that its safety protocols are designed to evolve. The company confirmed that the restoration of access to Fable 5 follows negotiations with the Trump Administration.
