OpenAI has developed a new artificial intelligence model, GPT-5.6-Cyber, designed to assist cybersecurity professionals in identifying potential vulnerabilities in computer systems. The model has already helped discover two previously unknown vulnerabilities in Google's Chrome browser. While access to the model requires identity verification, its capabilities are intended to give cybersecurity defenders a competitive edge in staying ahead of potential threats. This development is significant because it underscores the growing importance of AI in the field of cybersecurity and the need for defenders to stay ahead of emerging threats.
