OpenAI Daybreak / GPT5.5Cyber
OpenAI announced an expansion of Daybreak and GPT5.5Cyber for trusted defenders, saying Codex Security has scanned more than 30 million commits across over 30,000 codebases and that GPT5.5Cyber scored 85.6 on CyberGym, 39.5% on ExploitGym, and 69.8% on SEC-bench Pro. This is important because the same capability profile supports faster defensive patching while also demonstrating frontier-model competence at vulnerability validation and exploitation.
