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 strong model for trusted defenders - Cyber Partner Program: powering products built on top of our best cyber capabilities for 20+ leading security companies to secure the world's software - Patch the Planet: working with maintainers to secure critical open source projects With an update to GPT‑5.5‑Cyber, it’s now more permissive and more capable for advanced, authorized cybersecurity work. It is our most capable cyber model yet, with stronger performance on defensive workflows like tracing vulnerable code, validating issues, developing patches, and preparing evidence for human review. Codex Security brings these capabilities into real 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. 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 helps their customers benefit from advanced defensive AI, while keeping direct model access with trusted partners. Our goal is to move beyond using models to find more vulnerabilities, towards a world of safer software and cyber resilience. https://lnkd.in/eTjgMDUw
