Anthropic Vows Blocked AI Models Will Return 'In Coming Days' After White House Security Directive Halts Global Access

Anthropic vows its blocked frontier AI models, Mythos and Fable 5, will be restored 'in coming days' after a White House security directive halts global access, with Korea at the center of the controversy following a Chinese-linked telecom company allegedly triggering the U.S. export block.

• Anthropic expresses confidence that access to its blocked frontier AI models, Mythos and Fable 5, will be restored 'in the coming days' following a White House directive that cited security risks and halted availability globally.
• Korea sits at the center of the controversy after a Korean telecom company with suspected ties to China reportedly triggered the U.S. export block, while Project Glasswing — Anthropic's cybersecurity initiative controlling Mythos access — currently includes about 150 partners, among them Samsung, SK hynix, and SK Telecom.
• Despite the disruption, Anthropic reaffirms Korea as one of its fastest-growing markets, announcing ongoing team expansion and deepening investments, though industry insiders warn that repeated clashes with the U.S. government risk undermining trust in Anthropic's services.
