- OpenAI launches GPT‑5.4‑Cyber, a cyber‑protection variant of GPT‑5.4
- Mannequin provides reverse engineering and decrease refusal boundaries for defenders
- Obtainable by way of Trusted Entry for Cyber program, scaled to 1000’s of verified customers
The AI-powered cybersecurity race has reached a brand new stage after OpenAI introduced a brand new mannequin to rival Anthropic Mythos.
The corporate revealed the launch of GPT-5.4-Cyber, a modified model of the GPT-5.4 mannequin designed for cybersecurity protection operations.
The primary distinction is decrease refusal boundaries for official cybersecurity duties, which OpenAI describes because the device being extra “cyber-permissive.” The mannequin now comes with binary reverse engineering capabilities, permitting analysts to hunt for malicious code in packages and apps.

OpenAI is seemingly attempting to border Mythos’ restricted entry as a drawback, promising a extra “democratized” resolution as an alternative – and whereas GPT-5.4-Cyber will probably be extra open than Mythos, it nonetheless received’t be obtainable to anybody.
The device will nonetheless solely be obtainable to members of the Trusted Entry for Cyber (TAC) program, however OpenAI stated it’s now scaling it to “1000’s of verified particular person defenders and a whole bunch of groups accountable for defending important software program.”
This system will now have a tiered verification system, with the best tier unlocking GPT-5.4-Cyber. These excited by partaking in TAC can go to chatgpt.com/cyber, whereas enterprises are suggested to achieve out to their OpenAI consultant. Those that are already a part of this system can apply for larger tiers, as effectively.
OpenAI additionally stated the discharge is in preparation of an much more succesful AI mannequin, due later this 12 months. “In preparation for more and more extra succesful fashions from OpenAI over the following few months, we’re fine-tuning our fashions particularly to allow defensive cybersecurity use circumstances, beginning right now with a variant of GPT‑5.4 educated to be cyber-permissive: GPT‑5.4‑Cyber,” the announcement stated.
Mythos is an AI mannequin allegedly so highly effective that Antrhopic solely gave it to a handful of the largest software program firms, comparable to Microsoft, Apple, and Google. The device, they declare, was capable of finding decades-old vulnerabilities with ease which may, within the fallacious palms, be catastrophic.
