[OpenAI Launches New Model GPT-5.5-Cyber for Cybersecurity Teams] According to Jin10, OpenAI announced on Thursday that a variant of its latest AI model, GPT-5.5-Cyber, is being rolled out in a limited preview to vetted cybersecurity teams.

OpenAI emphasized that the preview version of GPT-5.5-Cyber is not designed to significantly enhance cybersecurity capabilities but has been trained to be more adaptable when handling security-related tasks. The company stated that with this version specifically tailored for the cybersecurity field, vetted teams will find it easier to leverage OpenAI's latest model for workflows such as vulnerability identification and classification, patch validation, and malware analysis.
