Anthropic PBC has disabled worldwide access to its most powerful artificial intelligence models, Claude Fable 5 and Claude Mythos 5, just days after their launch. The company switched the models off for all users late on Friday, June 12, following an export control directive from the U.S. government.
The decision came after the U.S. Commerce Department issued a sweeping export control order citing urgent security concerns. The directive ordered the company to suspend access to its latest AI models for any foreign national, underscoring Donald Trump's policy of export controls over high tech.
Rather than trying to enforce nationality rules selectively across a shared cloud service, Anthropic opted to disable the models globally. This marks the first time the U.S. government has taken such sweeping measures to rein in foreign access to frontier AI models developed by an American company.
