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.
