OpenAI Launches Project Daybreak and GPT-5.5-Cyber to Counter Anthropic’s Glasswing

OpenAI announced "Daybreak," a cybersecurity initiative that pairs GPT-5.5 models and Codex Security agents with partners (including Cisco, Palo Alto Networks, Cloudflare, CrowdStrike, Oracle, and Akamai) to shift security from reactive remediation to proactive secure-by-design practices, offering automated vulnerability scanning, patching, and specialized defensive and red-team simulation models; the piece frames this as a competitive response to Anthropic's Project Glasswing and highlights the enterprise monetization of AI-driven security.
