GPT‑6 Cyber: Advancing the frontier of aligned cybersecurity agents

On ExploitGym, which tests whether models can exploit a specified vulnerability, GPT‑6 Cyber scores 48.5%, up from 32.1% for GPT‑5.6 Cyber.

Advancing frontier cyber capabilities GPT‑6 Cyber is a major step up from GPT‑5.6 Cyber and outperforms GPT‑6 Astra on most cyber tasks, even when Astra does not refuse the request.

GPT‑6 Cyber shows a step-change improvement over GPT‑5.6 Cyber on this evaluation.

We’re also introducing a new group within Daybreak Red (Daybreak Red for Critical Infrastructure) for approved critical infrastructure defenders, which gives them permissions to conduct authorized testing of critical systems while retaining safeguards against model misalignment.

We will progressively expand access to all Daybreak Red customers soon, and are also making GPT‑5.6 Cyber available to all Daybreak Red customers.
