OpenAI is taking its cybersecurity game to the next level with the full release of GPT-5.5-Cyber and an updated Codex Security plugin. The new tools can automatically resolve vulnerabilities and patch software flaws, closing the gap between finding and fixing issues. This move is significant because it highlights the need for AI-powered solutions to keep up with the increasing complexity of modern software. As the threat landscape continues to evolve, OpenAI’s Daybreak initiative is well-positioned to help defenders stay ahead of attackers.
