At the urging of the US government, Anthropic abruptly took offline its newest AI models—Mythos 5 and Fable 5—blocking use by all foreign nationals including some company employees. This move has intensified calls worldwide for homegrown AI solutions to reduce dependence on American technology and assert digital sovereignty.
- US government demanded Anthropic block foreign user access to its latest AI
- European leaders cite shutdown as evidence for urgent AI sovereignty efforts
- Canada and China also emphasize homegrown AI to reduce foreign dependence
What happened
Over a single weekend, Anthropic suspended access to its most powerful AI models, Mythos 5 and Fable 5, following a direct request from the Trump administration. This directive required the company to block all foreign nationals, including its own international employees, from using the AI. The shutdown was sudden and executed with minimal prior notification or explanation from the US government.
The White House raised concerns about unauthorized foreign access, reportedly linked to Chinese entities, which partly motivated the move. The models had already incorporated safeguards for sensitive applications, yet the US weighed national security higher, enforcing the restriction despite the operational disruption for global users.
Why it matters
This unprecedented government intervention underscored the geopolitical power the US wields over frontier AI technologies, igniting alarm among allied nations who depend heavily on American AI platforms. Leaders in Europe and Canada immediately stressed that critical technologies like AI have become strategic assets, whose control is vital for national security and economic autonomy.
The incident served as a catalyst for accelerating efforts to build independent AI capabilities. UK officials framed AI sovereignty as essential to protecting the nation’s interests, France compared the cutoff to a strategic blockade, and Canadian leaders stressed the risks of overreliance on a single provider. The shutdown is shaping political conversations about digital sovereignty and investment priorities in AI development across multiple countries.
What to watch next
Global focus will likely intensify on sovereign AI initiatives, with governments pushing for increased funding and policy support for domestic AI startups and research to lessen reliance on US models. Europe's ongoing efforts to establish tech independence and regulatory frameworks will gain momentum, while Canada and other allies may deepen cooperation on alternative AI infrastructure.
Meanwhile, the US-China AI rivalry remains a critical factor, with allegations that Chinese firms have exploited Anthropic’s models for training adding fuel to concerns about intellectual property and national security. Monitoring how Washington balances security restrictions with maintaining competitive AI leadership will be key, as will observing whether other countries pursue more aggressive sovereign AI strategies or seek new multilateral agreements around AI governance.
