Reported GPT-6 Cyber Preview Signals a New Test for AI Security Markets

San Francisco, 25 September 2026 – OpenAI is reportedly preparing a preview of a cybersecurity-focused model called GPT-6 Cyber, potentially accompanied by a product for deploying it in security workflows. The company has not publicly confirmed the model or launch timetable. For investors and enterprise buyers, the distinction between an advance report and an official release is essential.

A preview may have narrower availability and different safeguards from a general launch.
