OpenAI is offering $1 billion in Daybreak credits for defenders
Building the future of cyber defense
Cybersecurity work that once required specialized tools, investigations, and many handoffs can now be broken into thousands of reasoning steps and worked through by capable models.
Daybreak turns that capability into a governed cyber defense stack: frontier models, the Codex harness, Codex Security, trusted workflows, and ecosystem partners—so defenders can reduce risk faster while keeping trusted access and action under human control.
Turn defense into a continuous loop
Daybreak delivers an agentic defense loop: inventory, discover, validate, assign, remediate, and prove. Together, Codex Security, GPT Cyber models, Patch the Planet(opens in a new window), and the Daybreak Defense Network bring governed defensive capability into the tools and workflows teams already use.
Governed by design
Frontier models can increasingly perform longer, more complex sequences of cyber work. Daybreak is built to put that capability in defenders’ hands responsibly—with human judgment, monitoring, safeguards, and community collaboration. Through Daybreak Access, verified defenders can access more capable and permissive defensive tools paired with stronger verification, scope controls, and oversight.

Daybreak for the frontline defenders who need it most
OpenAI is committing $1 billion in subsidized Daybreak access over six months to help protect the essential services and digital infrastructure we all depend on.
State and local governments, critical-infrastructure operators, community banks, nonprofits, and open-source maintainers can register their interest in support to find, prioritize, and fix security vulnerabilities.
Fixing the software the world runs on
Open source underpins much of the internet and an estimated 70–90% of modern software(opens in a new window). But many critical projects are maintained by small teams with limited time and funding.
OpenAI wants the people maintaining this shared infrastructure to benefit directly from frontier AI—not be overwhelmed by more unvalidated reports.
Patch the Planet, built with Trail of Bits, pairs frontier models with expert review to validate findings, develop and test patches, coordinate disclosure, and keep maintainers in control of what lands.
