A legal battle over artificial intelligence regulation is unfolding in the United States after Legion LegalTech filed a lawsuit against the federal government challenging an export-control order that restricted foreign access to some of Anthropic’s most advanced AI models. The dispute stems from a June 12 directive issued by the U.S. Commerce Department that required Anthropic to limit access to its Fable 5 and Mythos 5 models for foreign nationals. In response, Anthropic temporarily disabled access to the models for users worldwide while assessing compliance requirements.

Anthropic suspended global access to its Fable 5 and Mythos 5 AI models after a US Commerce Department directive, urging AI firms to consider relocating.

Anthropic's clash with regulators over AI export controls raises broader questions about cybersecurity, sovereign AI, and the future of government oversight.
