OpenAI's new GPT-5.5-Cyber model achieved a higher score on the CyberGym benchmark than Anthropic's Mythos AI, which was recently pulled offline by the U.S. government due to national security concerns.
OpenAI announced 'Patch the Planet,' a new initiative with Trail of Bits, HackerOne, and Calif. to offer free security consulting to open-source projects, aiming to improve their resilience against AI-powered hacking tools. The program also includes improved AI models and security scanners.
OpenAI said GPT-5.5-Cyber, a variation of its latest AI model, is rolling out in a limited preview capacity to vetted cybersecurity teams.
OpenAI announced it will launch GPT-5.5-Cyber, a specialized cybersecurity AI model, to a select group of trusted 'cyber defenders' in the next few days. CEO Sam Altman stated the model will not be available to the general public, with access limited to vetted institutions to allow them to strengthen their cyberdefenses. The company plans to work with the ecosystem and government to determine trusted access parameters. The staggered release follows a growing industry trend of restricting access to powerful AI models due to misuse concerns, similar to Anthropic's Claude Mythos release which faced White House opposition.
