OpenAI shifts AI security from finding bugs to auto-patching them
OpenAI just expanded its Daybreak initiative, launching an updated Codex Security plugin alongside its specialized GPT-5.5-Cyber model. The cyber model reached 85.6% on the CyberGym benchmark, beating GPT-5.5's 81.8%. Why it matters: AI has made surfacing vulnerabilities trivial, overwhelming defenders with alerts—now OpenAI wants models to validate issues, draft targeted patches, and fix code at machine speed.
