Cybersecurity Experts Urge Trump Administration to Lift AI Model Restrictions

A coalition of cybersecurity executives and experts has called on the Trump administration to rescind its directive restricting the use of Anthropic's latest artificial intelligence models by foreign nationals. The group argues that these restrictions could inadvertently aid U.S. adversaries more than they protect American interests.

Anthropic, a San Francisco-based AI company, announced Friday that it has taken its advanced AI models, named Fable 5 and Mythos 5, offline to comply with the administration's directive. The company stated that it did not believe the government's concerns regarding a potential security issue warranted such measures.

Anthropic had previously limited access to some of its newest technology, citing its advanced capability to identify and exploit computer vulnerabilities, potentially surpassing human cybersecurity experts. The company had engaged in discussions with the White House regarding these capabilities.

In a letter sent Sunday, over 100 cybersecurity professionals from companies including Adobe and Nvidia urged the U.S. government to remove the export control directives on Anthropic's models. They also called for the establishment of a transparent, scientific process for future AI risk assessments.

The signatories noted that while Anthropic's Mythos models are effective at identifying software flaws and weaponizing exploits, they are "not uniquely good at these tasks." Many experts regularly employ other foundation and open-source models for similar security audits and training purposes. The letter emphasized the potential danger of removing advanced cyber defense capabilities without sufficient justification, especially as U.S. adversaries are rapidly developing their own AI technologies.

According to the letter, Chinese AI models are "only months behind the best American models," and it is possible that China's government has access to capabilities beyond those publicly known. The export controls represent the most significant action taken by the U.S. government to date to limit access to cutting-edge AI systems. Fable, a more limited version of the advanced Mythos model, was released widely by Anthropic last week.

The directive was issued 10 days after President Donald Trump signed an executive order establishing a voluntary framework for vetting the national security risks of advanced AI systems before their public release.

Prior to these restrictions, tensions had been high between the Trump administration and Anthropic, which has advocated for safeguards in AI development to mitigate risks and enhance U.S. economic and national security. The company has also been involved in a dispute with the Pentagon, challenging an attempt by Defense Secretary Pete Hegseth to declare Anthropic a supply chain risk, a move the company contested in federal court. Anthropic sought assurances that its technology would not be used in fully autonomous weapons or for domestic surveillance, while Hegseth maintained the Pentagon should be allowed to use the technology for any lawful purposes.
