Anthropic is expanding access to its Claude Mythos AI model through Project Glasswing, a program meant to let tech and security firms and governments discover and fix bugs and potential exploits before the powerful model is publicly released.
“Following several weeks of close collaboration with our Project Glasswing partners, the security industry, open-source software maintainers, and the U.S. government, we’re extending the partnership to approximately 150 new organizations,” Anthropic wrote. “Each one will need to meet our security requirements before they gain access.”
The latest Project Glasswing expansion adds organizations from critical infrastructure sectors, including power, water, healthcare, communications, and hardware. Anthropic said many of the new organizations maintain software used by governments and hundreds of millions of people.
“What each partner has in common is that a successful attack on their codebase could be catastrophic,” Anthropic wrote. “For most partners, we estimate that a major attack could affect more than 100 million people, with important ramifications for both global and national security.”
The model's capabilities have raised concerns among researchers and government agencies that increasingly capable AI systems could make cyberattacks easier to execute.
Anthropic said it is expanding access to Mythos because it believes defenders need increasingly capable AI tools before attackers gain similar capabilities. The company said it expects other developers to release Mythos-class models within six to 12 months, potentially without comparable safeguards, raising the prospect of more frequent and less predictable cyberattacks.
“In the future, frontier model releases will become increasingly high-stakes. Capabilities will continue to improve across all domains, including many that—like cybersecurity—can empower attackers and defenders alike,” Anthropic wrote. “If we’re successful, we hope to enable a permanent advantage for defenders.”
Anthropic did not immediately respond to a request for comment by Decrypt.
