Anthropic has restored customer access to its powerful newest AI model, Fable, after a more than two-week blackout resulting from US government safety concerns that it could be abused to enable serious cyber-attacks.

The San Francisco company said export controls had been lifted, citing a social media post from the US commerce secretary, Howard Lutnick, in which he said: “Over the past two weeks, we have worked closely with Anthropic to analyze and approve Fable 5 to ensure alignment across the US Government and strengthen America’s leadership in AI.”
