WASHINGTON, May 11 (Reuters) – The U.S. Commerce Department removed details from its website about its agreement ​with Google, xAI and Microsoft to ‌test their artificial intelligence models for security vulnerabilities, according to a Reuters review of the agency’s site.

The link that previously led to the ‌department’s ​announcement about the testing ⁠is no longer ⁠available. As of Monday afternoon in Washington, it said, “Sorry, we cannot find that page.” The link later redirected to the Center ​for AI Standards and Innovation’s website, the government organization responsible for the ⁠tests.

The Commerce Department announced ⁠on May 5 that the ​companies would hand over new AI models before ​they deploy them to the public, ‌allowing government scientists to test them for security flaws.

Concern is growing in the U.S. government over the national security risks ⁠posed by powerful AI systems, including Anthropic’s Mythos. By securing early access to advanced models, U.S. ⁠officials ‌said they were aiming to ⁠identify threats ranging from cyberattacks ​to ‌military misuse. It was not immediately ​clear ⁠why the website was deleted.

Spokespeople for the Commerce Department and Trump White House did not immediately respond to a request for comment from Reuters.
