OpenAI Daybreak cybersecurity initiative targets vulnerabilities before attackers can exploit them
OpenAI unveiled Daybreak, a cybersecurity initiative that uses AI models including GPT-5.5 and Codex Security to find and patch software vulnerabilities. The launch positions OpenAI directly against Anthropic's Project Glasswing and Claude Mythos, as both AI giants race to tilt the balance in favor of defenders. Major partners including Cisco, Cloudflare, and CrowdStrike are already integrating the capabilities.
