Anthropic's Fable 5 and Mythos 5 shutdown sparks global sovereign AI push
White House orders Anthropic to cut foreign access to its most powerful models.
Anthropic, a leading US AI lab, was forced to pull its newest frontier models—Fable 5 and Mythos 5—offline over the weekend at the White House's request. The administration demanded that all foreign nationals, including Anthropic's own overseas employees, be blocked from accessing the models. The move was swift, sweeping, and offered little explanation, sparking immediate backlash abroad.
In the UK, AI minister Kanishka Narayan used the incident to argue for domestic AI capacity, calling it a national security issue. In France, former Prime Minister Gabriel Attal compared the shutdown to Iran blockading the Strait of Hormuz, describing it as the start of 'the AI war.' Canada’s Prime Minister Mark Carney urged diversification, stating that overreliance on any single partner for critical AI access is a risk. China, already investing heavily in domestic AI, now stands as one of the few regions with credible alternatives. The incident underscores how US dominance in frontier AI comes with geopolitical strings attached.
