Trump Administration Lifts Restrictions on Anthropic’s Claude Models After Cybersecurity Alarm

The Trump administration has lifted restrictions on Anthropic's Claude chatbot models after a weekslong ban triggered by cybersecurity concerns. The models were blocked in mid-June after Amazon security researchers discovered a way to bypass safeguards on Claude Fable 5 that could enable exploitation of software vulnerabilities. Anthropic's most powerful model, Mythos 5, is now accessible only to government-approved U.S. organizations, while Fable 5 has returned to wider availability, following Trump's executive order establishing a framework for vetting advanced AI systems before public release.
