The recent, albeit temporary, withdrawal of Anthropic's advanced AI models, Fable and Mythos, has significantly galvanized global initiatives towards developing sovereign AI capabilities.
Anthropic abruptly deactivated its cutting-edge Fable and Mythos AI models at the behest of the US government over the weekend. The American firm stated it was compelled to comply with a White House directive to restrict access for all foreign nationals, including its own staff. Internationally, this event served as a stark reminder that beyond its dominance in frontier AI, the US government possesses the authority to dictate access to these critical technologies.
The Trump administration's intervention was characterized by its speed, breadth, and lack of prior warning or detailed justification. The unprecedented deactivation of the Fable 5 and Mythos 5 models, despite existing safeguards restricting their deployment in “high-risk areas,” lent considerable weight to persistent concerns about over-reliance on the United States for essential technologies. This incident provided renewed impetus for political figures, administrations, and corporations advocating for indigenous leadership in technological development.
In the United Kingdom, AI and online safety minister Kanishka Narayan leveraged the shutdown to emphasize the imperative for Britain to cultivate its own AI capabilities, positioning it as a national security priority, though he refrained from explicitly naming Anthropic, Donald Trump, or the US. He declared, “We treat every other threat to our sovereignty with deadly seriousness, but we haven’t learned to treat this one in the same way,” a statement accompanied by visuals of British law enforcement and military. Narayan asserted that AI represents “the central political question of our time,” urging Britain to proactively determine the technology's impact on its economy, security, and sovereignty “before someone else decides the answer for us.”
France's response was notably more direct, explicitly identifying the US. Former Prime Minister Gabriel Attal, the presidential candidate for Emmanuel Macron’s Renaissance party, characterized the shutdown as the genesis of “the AI war,” highlighting France's susceptibility when dependent on external entities for critical technologies. He drew a parallel between the withdrawal of Anthropic’s models and Iran’s blockade of the Strait of Hormuz, presenting AI access as a strategic vulnerability demanding French preparedness. Attal's concerns were echoed across the French political landscape, as reported by Le Monde.
This debate is not entirely novel. Europe has long expressed apprehension regarding its technological and broader reliance on the US, prompting the European Union to increasingly prioritize reducing its dependence on foreign suppliers in sectors such as semiconductors, cloud computing, and AI. However, the Anthropic incident has imbued these concerns with a new urgency, exacerbating existing anxieties about America’s dependability as an ally under Trump, ranging from trade disputes to potential NATO withdrawal. Attal indicated this matter would be central to France’s upcoming presidential elections, while members of the European Parliament cited the deactivation of Mythos and Fable as compelling proof that Europe must swiftly achieve technological sovereignty.
Canada has gleaned a comparable insight to Europe. Prime Minister Mark Carney articulated that the circumstance underscores the peril of depending solely on a single partner for vital resources such as AI. He stated, “The situation we’re in collectively right now with Mythos and Fable is something that can happen with overreliance on certain models.” Carney further cautioned, “Nobody has done anything wrong in the situation. But we will have done something wrong if we just accept this, don’t take the lesson, don’t build out and diversify.”
Other nations are already significantly advanced in this pursuit. Beijing has consistently championed its domestic AI companies, positioning China as one of the rare global entities possessing models that can credibly compete with offerings from American frontier AI laboratories. Nevertheless, Chinese models still exhibit some deficiencies compared to their US counterparts in certain domains. Anthropic has, moreover, leveled accusations against Chinese competitors for leveraging its models to train their own on an “industrial” scale. A contributing factor to the White House’s reported decision to withdraw Mythos was its conviction that a China-affiliated group had gained access to the model.
The majority of governments and enterprises lack the capacity to replicate the scale and resources of leading AI laboratories in the US or China. Yet, the concept of sovereign AI does not exclusively entail developing the largest or most potent tools. Examples like France’s Mistral and Canada’s Cohere demonstrate that robust advancements can emerge from outside these major powers, even if their models do not directly rival the absolute frontier. Nations such as Singapore and the UAE have strategically concentrated on more specialized, yet critical, objectives, including infrastructure development or models optimized for local languages. Furthermore, the proliferation of open-source models presents a future possibility of Mythos-level capabilities that would inherently resist control by any single entity.
While the Trump administration may perceive the restriction of Mythos and Fable as a national security imperative, this perspective is inherently reciprocal. As Washington deliberates whether AI's significance precludes universal access, other nations are questioning the prudence of allowing Washington to unilaterally determine who can access these crucial technologies.
Anthropic's Mythos and Fable models are anticipated to be reinstated online in the near future. However, rebuilding international confidence in American AI presents a distinct and more formidable challenge. Irrespective of its duration, the shutdown starkly illuminated the inherent fragility of access to US frontier AI models. The implications of this event have been met with widespread disapproval by numerous governments and corporations, spurring them to ensure such a disruption is not repeated.
