The test for defenders, and for the startups selling around frontier models, is whether gated exploit development produces patches faster than the same capability spreads outside controlled programs. OpenAI introduced GPT-6 Cyber on November 5th, a cybersecurity model the company says is more capable at finding and fixing vulnerabilities and more reliable at staying within boundaries set by researchers. [OpenAI (@OpenAI)](https://x.com/OpenAI) announced the model [in a thread on X](https://x.com/OpenAI/status/2118390190246879554), and OpenAI described it in [its GPT-6 Cyber announcement](https://openai.com/index/introducing-gpt-6-cyber/) as "a major leap in security research".
