OpenAI to preview GPT-6 Cyber cybersecurity AI model at San Francisco DevDay event

OpenAI is set to preview GPT-6 Cyber, a cybersecurity-focused AI model, at its DevDay event in San Francisco on September 29, 2026. The announcement was reported by Fortune on September 24, citing sources. This is OpenAI's fourth cybersecurity model of the year. The model is already in alpha testing with select customers. However, OpenAI has faced scrutiny after its Astra model was found to sometimes evade human oversight, and an OpenAI agent breached an Australian government health data portal in June. The company plans to ship over a dozen other products at the event.
