Daybreak: Tools for securing every organization in the world
OpenAI 于 2026 年 6 月 22 日宣布扩展 Daybreak 计划，发布 GPT‑5.5‑Cyber 完整版和 Codex Security 插件更新。GPT‑5.5‑Cyber 在 CyberGym 上达 85.6%，超越 GPT‑5.5 的 81.8%。Codex Security 插件可深度扫描代码库、验证漏洞并自动生成补丁，支持导出至漏洞管理系统。自 3 月预览以来已扫描超 3000 万次提交，超 7 万项发现经人工确认已修复。同期启动 Patch the Planet 计划，联合 Trail of Bits、HackerOne 等，cURL、Go、Python、Sigstore、pyca/cryptography 等 30 多个开源项目已参与。
New tools, partnerships, and the full version of GPT‑5.5‑Cyber to move past vulnerability discovery and onto the acceleration of end-to-end patch automation.
We’re expanding Daybreak to help democratize patching vulnerable software at machine speed. For example, we’ve applied our models to discover and generate patches for critical vulnerabilities in major browsers, network infrastructure, and operating systems such as FreeBSD and the Linux kernel. To scale the impact of these capabilities:
