Washington lifts shutdown on Anthropic Claude models
Tap title to read story
The Trump administration has lifted federal restrictions on Anthropic’s flagship Claude Fable 5 and Mythos 5 artificial intelligence models, restoring global access on July 1, 2026, after a 19-day shutdown over national security concerns. The crisis began on June 12, 2026, when Amazon engineers alerted the U.S. Department of Commerce that Claude Fable 5 could be prompted to identify critical software vulnerabilities and generate exploit code. Commerce responded with an export control order affecting foreign nationals, forcing Anthropic into a worldwide suspension. Access was restored after negotiations and the deployment of a new safety classifier developed with major technology partners.
