ANTHROPIC will expand access to its latest AI models, allowing vetted
institutions to use Claude OPUS 5.5, Claude Sonnet 5.5 and Claude MYTHOS 5.1 for
cybersecurity testing, including "high-risk offensive tests" targeting critical
infrastructure such as the power grid, banks and aviation operations.
Participants in its "Project Glasswing"—US government agencies, financial
institutions and large software vendors—will receive access; new entrants
require joint ANTHROPIC–US government review. Red teams will be granted elevated
privileges for offensive testing, though actions likely to cause physical harm
or mass destruction are prohibited. Certified defensive cybersecurity teams may
use the models for malware reverse engineering and incident response.
