OpenAI and Anthropic have ignited a new front in the AI race by simultaneously unveiling specialized cybersecurity initiatives. OpenAI launched its 'Korea Cyber Action Plan' today, granting the South Korean government and private sectors access to its new GPT-5.5-Cyber model. In response, Anthropic announced 'Mythos,' a high-autonomy model capable of both identifying vulnerabilities and developing professional-grade cyber-exploits to test defenses, alongside its 'Project Glasswing' security alliance.
AI is evolving from passive detection tools into 'autonomous agents' for cybersecurity. Companies like Google and Anthropic are moving beyond simple vulnerability flagging to systems that proactively simulate attacks, prioritize real-world risks, and deploy autonomous remediation to harden networks before human engineers can even intervene.
Anthropic reported an unprecedented 80x growth in annualized revenue within the first quarter of 2026, pushing its private valuation toward $900 billion.
Which new AI model was announced this week as featuring advanced 'cold reasoning' and the ability to autonomously develop functional cyberattacks for security testing?
