President Donald Trump signed a June 2 executive order that sets up a voluntary framework for developers of covered frontier models to give the US government access for cybersecurity review for up to 30 days before release, while expressly rejecting any mandatory licensing or preclearance requirement. The order directs NSA, CISA, and NIST to build a classified benchmark for determining which models cross the covered threshold and creates an AI cybersecurity clearinghouse led by the Treasury Department. The framework closely echoes Anthropic's Project Glasswing, which gives vetted partners early access to Claude Mythos Preview to scan critical software for vulnerabilities.

    Anthropic expands Project Glasswing access to 150 additional organizations

    Campaign Scope Update

    Anthropic expands Project Glasswing on June 2, extending Claude Mythos Preview to 150 additional organizations across more than 15 countries after roughly 50 partners gained access in April. The broadened program covers organizations in power, water, healthcare, communications and hardware, including software vendors whose code is embedded in other organizations, and Anthropic says a major breach in these codebases could affect more than 100 million people.
