Overview
- OpenAI’s Daybreak, launched Monday, helps developers and security teams find vulnerabilities, validate fixes, and secure code faster using its latest GPT-5.5 models and prior cyber work.
- Daybreak uses Codex Security to scan a company’s code, build a threat model of likely attack paths, test suspected flaws in an isolated environment, and suggest concrete patches.
- OpenAI offers three tiers tailored to authorized use: GPT-5.5 for general work, GPT-5.5 with Trusted Access for verified defensive tasks, and GPT-5.5-Cyber for controlled red teaming and penetration testing.
- Companies can request a Daybreak assessment that includes a vulnerability scan, and OpenAI has not disclosed pricing for the service.
- OpenAI positions Daybreak as a defensive answer to Anthropic’s Mythos as researchers warn AI is speeding up bug discovery and exploitation, with partners like Cloudflare, Oracle, Cisco and others signing on under new safeguards and verification.
