US restricts foreign access to Anthropic’s Fable 5 and Mythos 5 AI models over security concerns

US authorities have mandated AI firm Anthropic to halt access to its Fable 5 and Mythos 5 models for non-US individuals, citing national security concerns and potential model vulnerabilities. The company, while complying, believes a misunderstanding may exist and is working to reinstate access. This move reportedly follows claims of 'jailbreaking' the AI.
