OpenAI launches GPT-6 Cyber for selected authorized security users
OpenAI announced GPT-6 Cyber on 5 November 2026 to find vulnerabilities, validate exploitation and develop fixes. It is initially restricted to selected approved Daybreak Red customers through the API and Codex.
OpenAI rates its cybersecurity capabilities as “Critical” under its own preparedness framework, up from “High” for GPT-5.6 Cyber. This is a capability rating, not evidence that an incident occurred.
On its internal ExploitGym test, the company reports a 48.5% success rate versus 32.1% for its predecessor. These are not independent assessments or guarantees of real-world safety. OpenAI plans to expand access gradually, subject to approval.
