Nov 8, 2026 · OpenAI launches GPT-6 Cyber and rates it 'Critical' for cybersecurity capability

OpenAI released GPT-6 Cyber on November 5, a version of GPT-6 Astra tuned for authorised vulnerability discovery, exploit development and penetration testing. It is the first model OpenAI has classified as 'Critical' under its Preparedness Framework, one step above the 'High' rating of its predecessor, and is available only to vetted customers in the company's Daybreak Red programme. OpenAI says the model found more than 80 previously unknown vulnerabilities in Firefox during testing.
