Trump Drops Restrictions: Anthropic’s Fable 5 and Mythos 5 Are Back After an 18-Day U.S. Export-Control Standoff

Anthropic's Fable 5 and Mythos 5 models are available globally again following an 18-day U.S. export-control shutdown. The Trump administration reversed the order after discussions, though Anthropic now operates under formal government oversight. The restrictions were initially imposed due to cybersecurity safety concerns shortly after Fable 5's public release. To facilitate the return, Anthropic implemented a new safety classifier and other measures to address the government's specific security concerns regarding the models' potential risks.
