OpenAI has made major strides in the cybersecurity community, with an improved version of its private, security specialized model GPT-5.5-Cyber. This model has been said to outperform its rival, Anthropic Mythos in defense testing. OpenAI also teamed up with cybersecurity firms to launch "Patch the Planet", an initiative that provides free consulting and AI tools to volunteers that maintain open-source software. This program aims to help developers quickly find and fix critical security bugs before malicious hackers can exploit them. Both OpenAI and Anthropic prepare to go public amid warnings from global intelligence agencies that AI is facilitating both cyber warfare and cyber defense.
