Cybersecurity
Capture-the-flag ranges, vulnerable network simulations, and secure-code review tasks where models learn to find, exploit, and patch vulnerabilities. Security environments serve a dual purpose: training more capable defensive agents and evaluating dangerous capabilities before deployment.
