OpenAI has officially unveiled 'Daybreak,' a comprehensive AI security initiative designed to proactively identify and patch software vulnerabilities. Utilizing the new GPT-5.5-Cyber model and the Codex Security agent, Daybreak aims to counteract the rise of AI-generated exploits. The move directly challenges Anthropic’s 'Claude Mythos' and its private 'Project Glasswing' initiative, marking a major shift in the industry toward defensive, specialized cyber-AI systems.
The AI industry is transitioning from general-purpose chatbots to 'defensive agents.' As AI-generated code vulnerabilities (CVEs) have tripled in early 2026, major labs like OpenAI and Anthropic are shifting focus toward 'Cyber-Sentinels'—AI models specifically trained to audit code, manage organization-wide threat models, and automate cybersecurity responses in real-time.
South Korean researchers successfully developed a 'warm-up' training phase that allows AI models to distinguish between known and unknown information, finally enabling chatbots to reliably say 'I don't know.'
Which new OpenAI initiative was launched on May 12, 2026, to compete with Anthropic's security-focused model, Claude Mythos?
