## Summary

OpenAI introduces GPT-6 Cyber, a security research model it says pairs stronger capabilities with better alignment. The model is available to select Daybreak Red customers, with access expanding over time, and OpenAI also launches Daybreak Red for Critical Infrastructure for authorized testing. An attached chart reports a 0.07% out-of-scope exploitation rate for GPT-6 Cyber versus 5.51% for GPT-5.6 Cyber on the ExploitGym Honeypot without deployment safety prompts.

## Post

GPT-6 Cyber: a major advance for security research, already being used to help defend security-critical software such as the Linux kernel, Firefox, and many other projects.

We’ve invested a great deal in trust, specifically training the model to stay within the scope specified by the operator. The corresponding eval results are quite striking.

We’re also launching Daybreak Red for Critical Infrastructure, giving approved critical infrastructure defenders the ability to conduct authorized testing of critical systems.
