# Daybreak | OpenAI for cybersecurity

## Retrieval answer

OpenAI has published Daybreak, a cybersecurity program combining frontier models, the Codex harness, Codex Security, trusted workflows, and partner services.

OpenAI has published Daybreak, a cybersecurity program combining frontier models, the Codex harness, Codex Security, trusted workflows, and partner services. Its stated defense loop covers inventory, discovery, dynamic validation, ownership assignment, remediation, and verification.

The company says it will provide $1 billion in subsidized Daybreak access over six months. State and local governments, critical-infrastructure operators, community banks, nonprofits, and open-source maintainers can register interest in support for finding, prioritizing, and fixing vulnerabilities. Verified defenders can apply for more capable defensive tools through Daybreak Access, which OpenAI says includes scope controls, monitoring, safeguards, and human oversight.

OpenAI reports $17 million in API credits and direct support, 65 codebases under review, 1,885 findings surfaced, 661 patches produced, and 458 patches accepted upstream. It describes Patch the Planet, built with Trail of Bits, as a program pairing models with expert review for validation, patch development, testing, and disclosure coordination.

The source does not state how the $1 billion will be allocated, the selection criteria, the detailed access terms, or independently verified outcome data.
