On Friday, AI company Anthropic shut down access to two of its newest models—Mythos 5 and Fable 5—after a White House order. The catch: Anthropic disabled them for all users worldwide, not just non-Americans, because it had no way to filter access by citizenship in time.
If you use Claude (Anthropic’s main chatbot) in Ghana, don’t panic. Your access to the standard Claude model is not affected. Only these two newer models have been pulled.
What happened?
On Friday evening, the U.S. government ordered Anthropic to block access to Mythos 5 and Fable 5 for “any foreign national, whether inside or outside the United States.” Fable 5 had just launched days earlier and, according to Anthropic, marked the first time the company released such an advanced model to the public.
The Trump administration cited national security concerns. Specifically, officials said there’s a potential way to trick Fable 5 into identifying software vulnerabilities—a risk they deemed too serious to allow overseas access. Anthropic disagreed with the decision but complied immediately.
Since the company couldn’t quickly build a system to verify citizenship at login, it switched off both models for everyone to ensure compliance.
Why does this matter?
For now, this is mainly a headache for developers and researchers who were testing Fable 5 or Mythos 5. Ordinary Ghanaians using ChatGPT-like tools won’t notice much—your standard Claude access remains open.
But it sets a concerning precedent. If governments can force AI companies to block entire models on short notice, future tools could disappear suddenly without warning. That uncertainty makes it harder for businesses to plan around these tools.
Anthropic has said it’s working to “restore access as soon as possible” and hopes the ban will be brief. Some industry observers think it could lift within days.
The bigger picture
This clash reflects rising tension between Anthropic and the U.S. government. Earlier this year, Anthropic refused to let the Pentagon use its models for domestic surveillance or fully autonomous weapons systems. In retaliation, the government added Anthropic to a supply chain blacklist.
The Defense Department’s chief information officer said on X: “Some things are simply more important than revenue cycles… America First. Always.”
On Reddit and social media, users criticized the move as short-sighted and impractical. Dean Ball, a senior fellow at the Foundation for American Innovation, called it “cartoonish” and “baffling” on X.
What you should watch
Keep an eye on whether Anthropic’s access is restored within days or weeks. If it stays disabled long-term, it signals that the U.S. is willing to weaponize AI regulation—which could affect other tools and companies globally.
If you’re developing with Claude, stick with the standard models for now. Fable 5 isn’t critical for most use cases, and you’ll avoid being caught off-guard if access doesn’t return quickly.
