The U.S. Commerce Department lifted export controls on Anthropic’s Fable 5 and Mythos 5 models on June 30, ending a three-week suspension triggered by national-security concerns. Anthropic said access to Fable 5 would resume globally July 1 across Claude Platform, Claude.ai, Claude Code and Claude Cowork, while Mythos 5 would remain limited to approved U.S. organizations. The restrictions began June 12 after the government directed Anthropic to block foreign nationals from accessing the models. Anthropic said it could not verify nationality in real time, so it disabled both models for all customers. The company said the government’s concerns followed an Amazon researchers’ report demonstrating a safeguard bypass that enabled Fable 5 to identify software vulnerabilities and produce exploit-related code. Reuters reported June 27 that restoration was under discussion, but the lifting was confirmed June 30. The episode highlights unresolved U.S. policy questions surrounding AI exports, cybersecurity risks and government oversight.
