OpenAI announced on Thursday the release of a limited preview of its latest AI model variant, GPT-5.5-Cyber, to vetted cybersecurity teams. According to Jin10, this follows a month after its competitor, Anthropic, garnered attention from investors and government officials with the preview version of Claude Mythos. OpenAI clarified that the preview version of GPT-5.5-Cyber is not intended to significantly enhance cybersecurity capabilities but is trained to be more adaptable in handling security-related tasks. The company stated that with this version specifically designed for the cybersecurity sector, vetted teams will find it easier to utilize OpenAI's latest model for workflows such as vulnerability identification and classification, patch verification, and malware analysis.
