Anthropic Blocks Foreign Access to AI Models

Anthropic disabled access for all foreign nationals to its most advanced AI models, Fable 5 and Mythos 5, after a request from the Trump administration citing national security concerns.

The US government feared the models could be diverted to foreign military intelligence.

The move has sparked a fierce debate over AI sovereignty, with South Korea's Upstage CEO saying it underscores the need for sovereign AI. Tech CEOs and security researchers have also urged the Commerce Secretary to reverse the restrictions, arguing they disarm cyber defenders.
