Anthropic disables Claude Fable 5 globally after US national security order

Anthropic disables Claude Fable 5 and Mythos 5 globally after US order restricting foreign access over national security concerns.

Anthropic has disabled its two most powerful artificial intelligence models worldwide after the US government ordered the company on Friday to cut off access for any foreign national, citing national security, the company said.

The directive, received at 5:21pm eastern time, required Anthropic to suspend all access to the models, Claude Fable 5 and Mythos 5, by any foreign national whether inside or outside the United States, including the company's own foreign-national employees, according to Anthropic and reported by CNBC and NBC News.

Because it cannot verify a user's nationality in real time, the company switched off both models for every customer rather than risk breaching the order.

All other Claude models remain available, and the company's landing page carried the line "Fable 5 is temporarily unavailable." The two systems had launched only days earlier, with Fable 5 billed as the most capable model Anthropic had released to the public.

A disputed jailbreak

The order was sent by Commerce Secretary Howard Lutnick and drafted with the department's Bureau of Industry and Security, an administration official told NBC News.

The government cited national-security authorities but, Anthropic Ai said, supplied only "verbal evidence of a potential narrow, non-universal jailbreak" rather than written specifics.

The concern, according to the company, centred on a technique that involved "asking the model to read a specific codebase and fix any software flaws."

Anthropic disputed that this warranted the action, saying it disagreed "that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people," and that the same weakness was "likely also present" in rival systems, naming OpenAI's GPT-5.5.

Anthropic said governments should be able to block unsafe deployments "as part of a statutory process that is transparent, fair, clear, and grounded in technical facts," adding that this order did not meet that standard.

The Commerce Department did not immediately respond to a request for comment, NBC News reported. It is the first time a leading AI company has pulled a publicly deployed model offline because of US federal intervention, the broadcaster said.

Months of friction with Washington

The shutdown is the latest turn in a dispute between Anthropic and the Trump administration that has run for months.

The friction stems from the company's acceptable-use policy, which bars Claude from powering fully autonomous weapons or domestic mass surveillance, restrictions the Department of Defense wanted lifted for all lawful military use.

Chief executive Dario Amodei refused to drop the guardrails, saying frontier AI was "simply not reliable enough to power fully autonomous weapons," according to reporting by NPR and Axios.

In late February the administration ordered federal agencies to stop using Anthropic products, and Defense Secretary Pete Hegseth labelled the company a "supply chain risk," a designation usually reserved for firms tied to foreign adversaries.

Anthropic sued the administration on 9 March to reverse the move. A federal judge in San Francisco, US District Judge Rita Lin, granted a preliminary injunction in late March blocking both the designation and the order barring federal agencies from using Claude, writing that nothing in the law supported "the Orwellian notion that an American company may be branded a potential adversary and saboteur of the US for expressing disagreement with the government," according to reporting by CNN and NPR.

Anthropic later lost a separate bid in April to have an appeals court pause the dispute, and the appeals court heard arguments on 19 May. The case is continuing.

Why it matters for Bangladesh

The episode marks the first time Washington has applied export-control logic, long used to restrict advanced computer chips, to an AI model itself, raising questions over which frontier tools will reach users in countries such as Bangladesh.

For Bangladeshi developers, freelancers and students who had begun using Claude's most advanced tier, the worldwide shutoff removed access overnight. Online freelancing and information-technology work are among the country's fastest-growing sources of foreign-currency earnings after remittances and ready-made garment exports, and access to leading AI tools has become an increasingly important input for that workforce.

It also underscores how the availability of such tools in markets like Bangladesh can depend on policy decisions taken in Washington rather than on local demand.
