US Halts Foreign Access to Anthropic's Top AI Models; South Korea Doubles Down on Sovereign AI

The US Commerce Department on June 12, 2026 ordered Anthropic to cut off all foreign nationals' access to its most advanced models, Fable 5 and Mythos 5, prompting the company to abruptly disable both models for every user worldwide the same day. The directive applies inside and outside the US and covers Anthropic's own foreign employees. Other Anthropic models are unaffected, according to Anthropic's statement and reporting by Reuters.
