Anthropic expands access to AI models for cybersecurity testing

Anthropic announced the expansion of access to its state-of-the-art AI models, allowing verified institutions to use models such as Claude Opus 5.5, Claude Sonnet 5.5, and Claude Mythos 5.1 for cybersecurity testing.

U.S. government agencies, financial institutions, and large software vendors participating in the "Project Glasswing" project will gain open eligibility, and newly joined institutions must be jointly reviewed by Anthropic and the U.S. government.
