We’re expanding OpenAI Daybreak to help democratize patching vulnerable software at machine speed:
- Codex Security plugin: find, validate, and fix vulnerabilities right inside Codex
- The full version of GPT-5.5-Cyber model: a great model for trusted defenders
- Cyber Partner Program: powering products built on top of our best cyber capabilities for leading security companies to secure the world's software
- Patch the Planet: working with maintainers to secure critical open source projects

Codex Security empowers defenders with out-of-the-box security workflows.
Teams can run deep scans, validate findings, trace attack paths, build threat models, generate codebase-specific patches for review, and export into the tools they already use.

GPT-5.5-Cyber is our most capable cyber model yet, designed for advanced, authorized defensive work: tracing vulnerable code, validating issues, developing patches, and preparing evidence for human review.

Patch the Planet is our effort to help open source maintainers move from security findings to merged fixes.
We’re working with Trail of Bits, HackerOne, Calif, researchers, and maintainers to bring Codex Security and advanced models into the remediation process, with human review at the center.

We’re also launching the OpenAI Daybreak Cyber Partner Program with leading security software and services providers.
Participating partners can use GPT‑5.5 with Trusted Access for Cyber in the security products and services they provide to customers.
This allows their customers to benefit from the model’s defensive capabilities and make their software more resilient, but keeps direct model access in the hands of participating partners.
