US Government Forces Anthropic to Disable Fable 5 and Mythos 5 Models
ByPulseAugur Editorial·[98 sources]·
Anthropic has been compelled by the U.S. government to disable its advanced AI models, Fable 5 and Mythos 5, citing national security risks and potential jailbreaking vulnerabilities. This unprecedented action, which bars foreign nationals from using the models, follows concerns reportedly raised by Amazon CEO Andy Jassy and Anthropic's own safety warnings. The shutdown has sparked debate about AI governance, geopolitical competition, and the future of frontier AI deployment, with some European figures viewing it as a wake-up call regarding dependence on U.S. AI technology.
