US government forces Anthropic to block its latest AI models, raising European concerns over American tech dominance
Executive summary: The US administration ordered Anthropic to block access to its latest AI models for foreign users, leading the company to disable Mythos 5 and related models for all users. The move signals US intent to control advanced AI technology and raises European fears of dependence on US AI capabilities.
Who is involved: Anthropic, US government (Trump administration), European policymakers and member states.
Likely next: European regulators may seek to develop sovereign AI initiatives, and US‑EU negotiations on AI export controls could intensify.
The United States ordered Anthropic to suspend access to its newest AI models, Mythos 5 and Fable 5, for non‑American users. Europe viewed the move as a signal of US intent to dominate the AI sector and prompted anxiety among French and broader European policymakers. The decision reflects growing geopolitical tensions around AI technology. No official EU response has been announced yet.
