On Friday night, Anthropic told the public that the U.S. government had ordered it to shut down access for foreign nationals—employees included—to its most advanced AI products.
The immediate impact was swift and blunt. To comply with the directive, the company announced it disabled access to Fable 5 and Mythos 5, the latest models of Claude, for all customers.
Anthropic said the government cited national security concerns, but it did not provide further details. In the company’s telling, its newest technology improves on earlier versions for both software engineering and visual understanding. But Anthropic has also acknowledged that its capabilities can be used in risky ways. releasing a preview model in April to a small group of industry partners to test for whether it could be used to create hacking tools.
Fable 5 is described as the first publicly available version of the Mythos model. Anthropic said it has built “guardrails,” including blocking answers to questions on cybersecurity, biology, and chemistry.
The move lands in the middle of a wider conflict between the Trump administration and Anthropic. In February, the Trump administration barred all federal agencies from using Anthropic products. That same day. Trump called Anthropic “a radical left. woke company” as his feud intensified over the company’s refusal to let the military use its technology.
At the time, CEO Dario Amodei said the U.S. government’s demands—mass surveillance of Americans and fully autonomous weapons—would allow it to break the company’s safeguard policies.
The tension isn’t theoretical. As the company has faced scrutiny, it has also been part of real U.S. military work. The U.S. military previously used Anthropic’s Claude for “intelligence assessments. target identification and simulating battle scenarios” to help prepare for its initial strikes on Iran.
Anthropic has positioned itself as an “ethical AI” company, a posture that has accompanied its fast rise even as public opposition to AI development has grown. This month, the company filed for an initial public offering.
And in a market moment that appears to underline how quickly the industry is moving, SpaceX’s entry into the stock market on Friday has helped push founder Elon Musk into the trillionaire tier so far, a development that could be a signal boost for both Anthropic and its major competitor OpenAI.
Still, the policy fight is also happening alongside a push from abroad. Other countries, including China and the United Arab Emirates, have been promoting “sovereign AI”—expanding their own AI infrastructure to reduce reliance on nations with their own data privacy and safeguard rules.
Despite the Trump administration’s pressure on Anthropic, developers are continuing to fund projects and build quickly. The government’s Friday night directive. though. has forced a pause at the top of the model line—turning the question of who gets access to advanced AI technology into a direct political and security issue. not a technical one.

So basically they’re locking foreigners out… which seems like a dumb move if it’s “for security.”
I don’t even get why they shut it down for everybody if it’s “foreign nationals” only. Sounds like they just hit the big red button and called it a day.
Wait, did they disable Claude because of the military thing? I swear I saw another headline that said it was banned for everyone in the government. Now it’s like only some models? Fable 5 and Mythos 5… I can’t keep track. Also “guardrails” don’t matter if people can just ask it the right way.
This is just more Trump vs AI drama. Like, if they’re worried about “hacking tools,” then why not just block the hacking questions and leave the rest? Turning off Fable 5 for all customers sounds like punishment for normal people who probably aren’t even doing anything. And “employees included” ??? so they’re saying the workers can’t use their own product now? Makes no sense. I’m sure it’ll get reversed when it benefits somebody.
