🎉 Congrats on GPT-5.5-Cyber's progress on CyberGym! CyberGym is part of our newly launched Frontier AI Cybersecurity Observatory, our effort to provide realistic, reproducible evaluations and continuous public measurements of frontier AI systems on real-world cybersecurity tasks. In addition to CyberGym, the Observatory includes benchmarks such as ExploitGym and CyberGym-E2E, providing a comprehensive view of frontier AI cybersecurity capabilities across vulnerability discovery, exploitation, patching, and end-to-end security workflows. Really excited to see that CyberGym and the Frontier AI Cybersecurity Observatory have become important guideposts for frontier AI cybersecurity development—enabling the community to track progress, understand emerging capabilities, advance AI systems that strengthen defensive security, and identify and mitigate potential risks arising from increasingly capable offensive cyber capabilities. 📣
