The Trump administration's decision that forced Anthropic to pull its latest cybersecurity models could be reactionary, retaliatory, or both, but the message is clear: The AI industry isn't immune from U.S. government interference.

Anthropic disabled Fable 5 and Mythos 5 after a US export-control directive, raising new questions about AI access and governance.

Anthropic was already navigating one dispute with the government in its standoff with the Pentagon, and then came an order on June 12th to block off foreign access to its most recently released AI models, Fable 5 and Mythos 5. When they launched on June 9th, Anthropic said “Fable 5’s capabilities exceed those of any model we’ve ever made generally available,” and that Claude Mythos 5 had the same underlying model, “but with the safeguards lifted in some areas.”

According to reports, the order came after conversations between Amazon and the White House about researchers saying they found ways to get Fable 5 to serve information that could be used in cyberattacks.

Anthropic responded by shutting access to both models for all customers, saying, “We are complying with the government’s legal directive and are removing access to Fable 5 and Mythos 5 for all users. However, we disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people.”

At Washington's request, Anthropic suddenly took its newest and most powerful AI models offline over the weekend. The American company said it had little choice after the White House demanded it block access for all foreign nationals, including its own employees. Abroad, the incident offered a sobering reminder that the US not only dominates frontier AI - its government also wields power over who gets to use it.

The Trump administration's action was swift, sweeping, and imposed with little warning or explanation. The unprecedented shutdown of the Fable 5 and Mythos 5 models - which were already subject to safeguards limiting their use in " …

A group made up of dozens of cybersecurity experts urged the White House to remove export-control restrictions on Anthropic’s Fable and Mythos models, arguing that the order is going to limit the ability of cybersecurity defenders to secure their software and products.

Apenas dias após o lançamento, o governo norte-americano emitiu uma diretiva de controlo de exportações que obrigou a Anthropic a desligar globalmente os seus dois modelos mais avançados. A Comissão Europeia reagiu com preocupação e invocou soberania tecnológica.
