Anthropic is expanding a program that allows vetted cybersecurity professionals to test its most powerful AI models with fewer safeguards, after its Project Glasswing initiative helped uncover more than 100,000 software vulnerabilities this year. Its partners under Glasswing, an initiative aimed at securing the world's most critical software, found at least 129,000 verified vulnerabilities between April and July. Anthropic's own open-source scanning found 5,500 more between April and October.
