OpenAI expands Daybreak cybersecurity tools for patching vulnerabilities.
OpenAI announced an expansion of its Daybreak cybersecurity initiative, including updates to Codex Security, GPT-5.5-Cyber, a partner program, and the Patch the Planet initiative for open-source projects. The stated focus is moving from vulnerability discovery to validation, remediation, and patch deployment. OpenAI says Codex Security has scanned more than 30 million commits across over 30,000 repositories since its research preview. SecurityWeek reported the expansion today as a shift toward AI-assisted patching workflows for defenders.
