OpenAI just launched a new cybersecurity product called 'Daybreak' that pairs GPT-5.5 with Codex to act as an agentic security team across a codebase. The product scans repositories, identifies vulnerabilities, generates patches, and automates detection and response. It ships with three access tiers, each with increasingly stricter permissions: - A base tier that runs standard GPT-5.5 for general security workflows - A "Trusted Access for Cyber" tier that loosens model safeguards for defensive security operations - A GPT-5.5-Cyber tier for specialized offensive work Daybreak also builds a threat model directly from your repository and focuses on "realistic attack paths," reasoning about how an attacker would move through the code. Eight security firms partnered at launch: Cloudflare, Cisco, CrowdStrike, Palo Alto Networks, Oracle, Zscaler, Akamai, and Fortinet.
