## OpenAI launches specialized cyber model
OpenAI has released GPT-6 Cyber, an AI model designed for cybersecurity professionals. The company says it outperforms its general-purpose GPT-6 Astra model on most cyber tasks.
## Access limited to approved customers
Because the model could be used to conduct cyberattacks if it fell into the wrong hands, OpenAI is making GPT-6 Cyber available only to a small handful of approved security customers.
## Cyber defense spending doubles
Gartner forecast in September that worldwide AI cybersecurity spending would reach fifty-one point three billion dollars this year, nearly double last year's twenty-five point nine billion dollars.
## OpenAI's fourth cyber model this year
This is OpenAI's fourth cybersecurity-focused model this year, following versions released in April, June and August. The company also hired chief revenue officer Dali Rajic from a cybersecurity software background.
## Model finds hundreds of new vulnerabilities
OpenAI tested GPT-6 Cyber on Firefox and the Linux kernel.Researchers found eighty-one previously unknown high-severity Firefox vulnerabilities and developed working exploits for nine hundred forty-eight Linux kernel vulnerabilities, including five hundred eighty-eight previously unknown flaws.
## Expanded access coming for approved users
GPT-6 Cyber will initially be available to a select group of approved Daybreak Red customers only, with access expanding to all Red customers over the coming weeks.
## Key takeaway

OpenAI released GPT-6 Cyber, a specialized cybersecurity model, to approved customers only, as AI-driven cyber threats intensify and defense spending surges.
