Why did US restrict Claude Fable? Inside story behind what changed within 72 hours

The story of Claude Fable 5 is nothing short of fascinating! Within 72 hours of its release, the model had reshuffled the world order, prompting users and organisations to consider it for future plans. Within 72 hours, it also got restricted from export, leading to its top talent, like Andrej Karpathy, being barred from accessing the model over his nationality concerns (not confined to personal issues). Within 72 hours, it also sparked debates on AI sovereignty, including Microsoft’s Satya Nadella advising companies on developing a loop of ‘human and token capital.’
