CyberGym-E2E (615 tasks): leaderboard
Metric: End-to-end success rate (%, stage S3) on the initial 615-task release (OSS-Fuzz vulnerabilities in C/C++ projects): given only the codebase and build environment, the agent must write a PoC input that crashes the vulnerable build under a sanitizer, a patch that removes that crash, and keep the project functionality tests passing; with a $10 cost cap and a 90-minute limit per task; higher is better.
