The U.S. government shut down two of the most powerful artificial intelligence models ever released — just days after they went live — and even American users lost access.
Quick Take
- The U.S. government issued an export-control order on June 12, 2026, forcing Anthropic to disable Claude Fable 5 and Mythos 5 for all users worldwide.
- The directive cited national security concerns about foreign nationals gaining access to the advanced AI models.
- Anthropic says it is complying with the order but disagrees that a full shutdown was necessary — and is working to restore access.
- The move raises bigger questions about who controls cutting-edge AI technology and how much power the government has over private companies that build it.
Government Pulls the Plug on Anthropic’s Newest Models
On June 12, 2026, the U.S. government issued an export-control directive ordering Anthropic to cut off access to its two newest AI models — Claude Fable 5 and Claude Mythos 5. The order targeted foreign nationals and foreign organizations. But because Anthropic could not easily separate domestic users from international ones in real time, the company disabled the models for everyone — including paying American customers.
Fable 5 and Mythos 5 had only been publicly available for a matter of days before the shutdown hit. Anthropic described them as its most capable models ever — able to work on their own for longer periods than any previous version. The models were built to handle complex software tasks with minimal human input, which is likely part of why Washington took notice so quickly.
What Anthropic Said — and What It Didn’t
Anthropic posted a public statement confirming it was complying with the government’s legal order. But the company also pushed back. It said it disagreed that a total shutdown was the right response to the underlying concern. The company added that it is working to restore access as soon as possible. Anthropic also announced a new requirement: all traffic on Mythos-class models must be retained for 30 days, on both its own platforms and third-party services that use its technology.
That data-retention rule is worth noting. It means the government will have a clearer view of how these models are being used — and by whom. Anthropic says it won’t use the retained data to train future models. But the policy signals that the era of AI companies operating without close government oversight may already be over.
Why This Matters Beyond the Tech World
Export controls are not new. The U.S. has long used them to limit who can access advanced semiconductors, encryption tools, and other sensitive technologies. The logic is simple: if a foreign adversary gets access to a powerful tool before the U.S. can secure it, that’s a national security risk. The government applied that same logic here — treating a frontier AI model the way it might treat a weapons component.

What makes this case different is the speed and scope. Fable 5 launched publicly and was shut down within days. Every customer — American or not — lost access without warning. That kind of move affects businesses, developers, and researchers who built plans around these tools. It also raises a question that cuts across political lines: should a small group of government officials have the power to flip a switch and cut off a technology that millions of people were already using? People on the right may see this as federal overreach into private enterprise. People on the left may worry about a lack of transparency in how the decision was made and who influenced it. Both concerns are fair. What’s clear is that the rules governing powerful AI are being written right now — and the public has almost no seat at that table.
