Sam Sabin
Summary
OpenAI is releasing an updated version of its GPT-5.5-Cyber model, making it more permissive and capable for authorized cybersecurity work. The model is only available to vetted cybersecurity companies and researchers. This comes as competition heats up between AI companies to provide advanced AI tools to cyber defenders, while Anthropic's similar offering (Fable) remains in regulatory limbo with the U.S. government.
