The White House vs. Anthropic's New AI Model

The government says this is about national security. But given the history—and ongoing litigation—between the White House and Anthropic, something more may be going on.

Is the Trump administration just hellbent on thwarting Anthropic now? Citing "national security" concerns, it has effectively killed public access to Anthropic's latest artificial intelligence model. The move sure looks like payback for Anthropic's earlier refusal to grant the government the right to use its products for mass surveillance and robot weapons.

Antrhopic's newest public-facing model is called Claude Fable 5. Launched on June 9, it was billed as a "safe for general use" version of Claude Mythos 5, Anthropic's powerful new AI model that was released only to "a small group of cyberdefenders and infrastructure providers…in collaboration with the US government."

The White House told Anthropic in a Friday letter that under a new export control directive, Mythos and Fable 5 could not be used by any foreign national in the U.S.—including Anthropic employees here on work visas—or anyone in a foreign country.

With no way to immediately comply with that, Anthropic temporarily ended public access for everyone.

Does Fable Pose a National Security Threat?

The government cited national security as the reason for its new directive, but its letter "did not provide specific details of its national security concern," noted Anthropic on Friday.

"Our understanding is that the government believes it has become aware of a method of bypassing, or 'jailbreaking' Fable 5," Anthropic continued.

This jibes with what Axios has reported: that the White House acted "after an urgent report from Amazon" that "they were able to jailbreak and access portions of Anthropic's powerful new Mythos model that pose a national security threat."

But according to Anthropic, the hubub comes down to "a small number of previously known, minor vulnerabilities." These "all appear relatively simple, and we have found that other publicly-available models are able to discover them as well without requiring a bypass." The company has "not even received a disclosure of a concerning non-universal potential jailbreak that led to a harmful result. The potential jailbreaks that have been disclosed to us are either entirely benign responses or are minor findings that provide no Mythos-specific uplift," it said.

To comply with the Trump administration's new directive, Anthropic blocked all access to Fable 5 and Mythos 5 for now.

It says it is "working to restore access as soon as possible."

Is This Retaliation?

"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," Anthropic stated in its Friday post. "If this standard was applied across the industry, we believe it would essentially halt all new model deployments for all frontier model providers."

"We believe the government should have the ability to block unsafe deployments, as part of a statutory process that is transparent, fair, clear, and grounded in technical facts," it added. "This action does not adhere to those principles."

Anthropic didn't outright accuse the administration of retaliation.

Extent to which White House allies are signaling that this is a culture war issue, not a technical one, is striking https://t.co/1fgoJEJn64

But Anthropic has been in the White House's crosshairs for months, since the company—which had a contract with the Department of Defense—refused to remove limits on........
