What smart people are saying about the return of Anthropic's Fable 5

Anthropic is restoring general access to Fable 5 after weekslong negotiations with the Trump administration to lift unprecedented restrictions on the powerful AI model.

The AI startup said on Tuesday that the Department of Commerce has lifted export controls that prompted it to disable access to Fable 5.

Anthropic added that it has also restored access to its more advanced Mythos 5 model to a vetted group of organizations after securing US government approval last week.

The dispute began in June after the White House imposed restrictions on the AI models over concerns they could be misused by adversaries for cyberattacks.

Anthropic said there had been a misunderstanding over a potential Fable 5 jailbreak and sent senior executives to Washington to negotiate a resolution.

The return of the models, which Anthropic said come with additional safeguards, marks a significant moment in the debate over how governments should regulate frontier AI systems.
