Anthropic has restored global access to Fable 5, two weeks after the Trump administration slapped export controls on the company’s most powerful AI model, citing security concerns.
The AI company announced Tuesday the controls had been relaxed, a shift also confirmed by U.S. Commerce Secretary Howard Lutnick, who wrote on X the government had spent the past two weeks working with Anthropic to ensure Fable had “alignment” with U.S. interests.
Access to Fable, as well as to a related model produced by Anthropic called Mythos 5, has been restricted since mid June. The U.S. government first banned the models’ use by foreign nationals, but because the ban applied to users regardless of whether they were inside or outside the U.S., and would have also applied to foreign Anthropic employees, the company quickly announced it would be suspending access for all users.
The Trump administration said the decision had been taken on national security grounds, fearing the possibility hostile actors could “jailbreak” the models and bypass the built-in guardrails designed to prevent malicious use.
But those restrictions turned out to be short-lived. Last week, the government allowed Anthropic to release its Mythos model to a select group of over 100 U.S.-based companies and federal agencies, partially undoing the restrictions. The move mirrored Anthropic’s own strategy when the powerful models were first released. The company first unveiled Mythos to an exclusive group of users earlier this year, before rolling out Fable, a version with the same underlying capabilities with more guardrails and safety filters designed for general use.
