Anthropic is broadening its cutting-edge AI program to Australian shores, with the company confirming that local organisations are now included in its Project Glasswing early access initiative. The expansion brings the total number of participating organisations to up to 150 across more than 15 countries, all gaining access to Anthropic’s powerful Claude Mythos Preview model. Access remains tightly controlled, with participation limited to organisations involved in defending critical infrastructure or operating across key sectors including power, water, healthcare, communications, financial services, and national security.
Claude Mythos Preview has already demonstrated significant cybersecurity capabilities, having been credited with identifying thousands of vulnerabilities at varying severity levels across open-source code bases. The model’s potential in the security space has drawn considerable attention, particularly following Microsoft’s own AI-powered MDASH vulnerability scanner discovering four critical remote code execution flaws in the Windows operating system in May 2026. However, Anthropic has noted that the model appears less effective when applied to extensively vetted code bases, suggesting its strengths are more pronounced in broader vulnerability discovery efforts.
Anthropic has stressed that its primary concern surrounding Mythos-class models is the risk of them being released publicly without adequate safeguards to prevent misuse. The company warned that threat actors are already leveraging large language models to uncover new and potentially devastating vulnerabilities at scale, making it “imperative cyber defenders adapt to maintain pace.” Anthropic also acknowledged it will likely not be the only AI firm to release models of this class, underscoring the urgency for responsible deployment frameworks across the industry.
