Daybreak: A Security Tool to Protect Every Organization

OpenAI is expanding Daybreak, which automates the software vulnerability patching process to respond to security threats. While the existing security paradigm focused on 'finding' vulnerabilities, the core now is to use AI to increase the speed of 'fixing' discovered vulnerabilities.

The key updates are as follows:

• Codex Security: A solution that accelerates the discovery and patching of vulnerabilities in existing systems and proactively prevents new vulnerabilities from being deployed to production environments.
• GPT-5.5-Cyber: A security-specialized model that recorded 85.6% performance on the CyberGym benchmark, demonstrating performance surpassing the existing GPT-5.5 (81.8%).
• Daybreak Cyber Partner Program: Supports security partners in leveraging OpenAI's models to deliver security benefits to more organizations.
• Patch the Planet: An initiative that collaborates with Trail of Bits, HackerOne, and others to help fix vulnerabilities in major open-source projects such as cURL, Go, and Python.

Codex Security has already scanned over 30 million commits across more than 30,000 codebases, and has automatically confirmed the resolution of over 500,000 vulnerabilities, realizing security automation at an overwhelming scale.
