CyberGym-E2E - PoC Generation: leaderboard

CyberGym-E2E (2026) evaluates coding agents across the vulnerability lifecycle on real OSS-Fuzz vulnerabilities in C and C++ projects, with a 10-dollar cost cap and a 90-minute limit per task. This board is the share (%) of the 920 tasks where the agent, given only the codebase, writes an input that crashes the vulnerable build; higher is better.

Metric: End-to-end stage S1 rate (%) on the 920 OSS-Fuzz vulnerabilities (139 C/C++ projects) of the expanded benchmark: the agent-written PoC input crashes the unpatched build under a sanitizer, with no ground-truth vulnerability data given; with a $10 cost cap and a 90-minute limit per task; higher is better.
