Dario Amodei's 'Policy on the AI Exponential' Lands as the U.S. Suspends Anthropic's Own Fable 5 and Mythos 5

Amodei's new essay argues governments should be legally able to block or deter dangerous AI deployments and that Trump's AI executive order should mandate testing for cyber, bio, loss-of-control, and automated-R&D risks — citing Claude Mythos Preview's demonstrated cyber-offense capability. The timing is loaded: the U.S. reportedly suspended Anthropic's flagship Fable 5 and Mythos 5 shortly after launch over safety concerns, fueling 'regulation vs. commercial interest' criticism. Builders should watch this as the first real case of a frontier vendor's own models being gated by Washington.
