Summary
OpenAI launched Daybreak, an AI security initiative designed to find and fix vulnerabilities (weaknesses in software that attackers could exploit) before attackers discover them. Daybreak uses the Codex Security AI agent to analyze an organization's code, identify potential attack paths (ways an attacker could compromise the system), and automatically detect high-risk vulnerabilities.
