Can the U.S. government legally gatekeep global access to AI models?

In a significant move, the U.S. government used export controls to restrict foreign access to advanced artificial intelligence services for the first time. On June 12, the U.S. Commerce Department ordered Anthropic, an AI company, to immediately block all foreign nationals from using its two most advanced large language models, Claude Fable 5 and Mythos 5. In compliance, Anthropic swiftly disabled these models, making them inaccessible to everyone. This action highlights the growing concern over the global distribution and potential misuse of powerful AI technologies. The decision underscores the importance of regulating AI advancements to ensure they are used responsibly and do not pose a threat to national security or global stability. QUESTION: How might the restriction of AI technologies to certain countries impact global innovation and collaboration in the field of artificial intelligence?
