  • Anthropic introduces Project Glasswing to use its frontier model, Claude Mythos, to identify and remedy security vulnerabilities in collaboration with major tech firms.
  • The model, which has found thousands of high-severity zero-day vulnerabilities, demonstrates capabilities that can surpass skilled human programmers in exploiting software vulnerabilities.
  • Due to potential risks and capabilities of misuse, Anthropic has opted not to make the model publicly accessible.
  • Project Glasswing aims to harness the model’s capabilities for defensive purposes before they can be used maliciously, committing up to $100 million in usage credits for Mythos Preview.
  • Anthropic emphasizes that the model’s dangerous capabilities emerged from general code, reasoning, and autonomy improvements, making it dual-purpose in its effects.
  • Recent leaks have exposed vulnerabilities in Anthropic’s other products, including a bypass of safety measures in its AI coding agent, raising further concerns about security handling.
