Anthropic will merge Project Glasswing into its existing Cyber Verification Program (CVP) to create an expanded, tiered program that gives vetted security professionals access to advanced AI cyber capabilities with varying levels of safeguards that experts say may or may not prevent misuse.
The Project Glasswing initiative consists of a tightly vetted group of companies that includes more than 40 organizations, such as Amazon, Apple, Microsoft, Google, Linux Foundation, JP Morgan Chase, NVIDA, and several others. It gives access to Claude Mythos, Anthropic's most advanced cyber large language model (LLM). The company decided to limit broader access because of the frontier technology's dual-use potential for abuse by threat actors; Mythos, Anthropic said, significantly accelerates vulnerability discovery.
The CVP previously covered two other models, Claude Opus and Sonnet, with a single level of access. After adding Project Glasswing, it will now grant certain organizations three different levels of cyber capabilities.
"Each tier includes access to our most capable models, including Claude Opus 5.5, Claude Sonnet 5.5, Claude Mythos 5.1, and new models moving forward," Anthropic's Oct. 6 announcement read. The expanded CVP turns the two programs into a single, ongoing access system, and security professionals can now apply for access based on the type and risk level of their work.
