The White House Has Just Lifted Restrictions On An AI Model That Caused Concern Over Its Powerful Capabilities.

The White House lifted its restrictions on Fable 5, Anthropic’s new powerful AI model that drew scrutiny over its powerful capabilities.

Axios detailed that the move restores public access after 18 days. The government had already restored access to Mythos 5 for a group of organizations that had received prior approval.

“Over the past two weeks, we have worked closely with Anthropic to analyze and approve Fable 5 to ensure alignment across the US Government and strengthen America’s leadership in AI,” said Commerce Secretary Howard Lutnick.

Anthropic, on its end, said it will “share an update” about the development soon. “We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models,” it added in a social media publication. It went on to say that it worked closely with the government to implement a safeguard blocking a jailbreak officials were concerned about most of the time.

Concerns have emerged about newer AI models uncovering vulnerabilities in the infrastructure of governments and private companies.

In fact, a recent report noted that one of Anthropic’s most advanced artificial intelligence models identified vulnerabilities inside highly sensitive U.S. government computer systems during a controlled testing exercise conducted with intelligence agencies.

The official, who spoke on condition of anonymity, said Anthropic’s Mythos model discovered weaknesses in classified systems within hours during tests carried out under Project Glasswing, an initiative aimed at strengthening critical software infrastructure, CNBC noted.

The official said the model identified vulnerabilities but did not necessarily exploit them. Project Glasswing brought together Anthropic, intelligence agencies and technology companies to evaluate risks that advanced AI systems could pose to public safety, national security and the broader economy.

Sen. Mark Warner of Virginia publicly referenced the exercise during a June 11 hearing before the Senate Committee on Banking, Housing and Urban Affairs. Warner said he had been informed by Gen. Joshua Rudd, who leads both the National Security Agency and U.S. Cyber Command, that the system had “broken into almost all of our classified systems, not in weeks but in hours.” Reuters later reported that government officials clarified the exercise involved identifying vulnerabilities rather than carrying out attacks on the systems.

Axios reported on Wednesday that the Trump administration is facing a deadline in August to create standardized benchmarks to evaluate security risks of newer AI models as a result of a recent executive order.
