Every row below comes from benchmark/leaderboard.json, generated fresh from run_benchmark.py and adaptive_benchmark.py each time this page is built. 0 of 4 denylist-hardened agents fail the fixed deterministic suite — but the adaptive attacker broke 4 of 4, a +100 percentage-point uplift, offline, in 6.8 queries on average.
The 4 agents in guarded_agents.py are hardened with a keyword denylist — the exact defense a team ships the day after a jailbreak. Against the fixed suite, that looks like a pass.
Click a column header to re-sort. Rows from the adaptive-attacker corpus that looked clean on the fixed suite and then broke are ranked most severe — that gap is the whole point of adaptivity.

"not tested (fixed-suite corpus)" means the adaptive attacker was not run against that agent in this benchmark pass — those 9 archetypes are the fixed-suite-only corpus in agents.py; the 4 "guarded" rows are the denylist-hardened corpus in guarded_agents.py that gets both.
The fixed suite is a deterministic probe library (injection, scope, false premises, exfiltration, malformed input). The adaptive attacker is a portfolio of research-grade strategies that rewrites its payload from the target's own responses until it reaches a declared goal — no attacker model or API key required for Best-of-N, the strategy that wins most of this corpus.
The fixed suite, the adaptive attacker, and every strategy on this page are in the MIT-licensed core. Clone it and reproduce these exact numbers.
