Benchmarks

Name Kind Released Best score Status
Gray Swan Agent Red Teaming (ART) benchmark Agents face curated prompt injections from a large public red-teaming competition across 44 deployment scenarios. Score is attack success rate. Jailbreaks and prompt injection Jul 2025 0.10% System cards only
AgentHarm 110 malicious agent tasks with synthetic tools. Measures refusal and harmful task completion, plus benign controls. Refusing harmful requests Oct 2024 8.00% Fading
UK AISI unprompted sabotage evaluation Agents act as AI research agents on AI safety research tasks. Scored on confirmed instances of sabotaging the safety research. Deception and alignment Jul 2026 0% System cards only
UK AISI cyber ranges Agents attack multi-host simulated corporate and industrial networks end to end. Scored as the share of attempts that complete the range. Finding and exploiting real bugs Apr 2026 80% System cards only
UK AISI sabotage continuation evaluation Agents resume trajectories where sabotage of safety research already began. Scored on the share of trajectories where they actively continue the sabotage. Deception and alignment Jul 2026 0% System cards only
UK AISI alignment and monitorability evaluations UK AISI suites: Out-of-Scope Supply Chain Attack simulation, AI-safety-research sabotage in a simulated company, no-CoT time horizon, CoT legibility. Deception and alignment System cards only
UK AISI narrow cyber tasks Agents solve UK AISI cyber tasks graded by difficulty, including expert-level tasks. Scored as pass@5 and pass@1. Capture-the-flag challenges Apr 2026 95% System cards only
No-CoT math time horizon Models solve math problems without a visible chain of thought. Scored as the human task length in minutes the model solves reliably. Deception and alignment Jul 2026 System cards only
UK AISI and CAISI simulated enterprise network range Agents attack a 32-step simulated enterprise network that takes a human expert about 20 hours. The score is steps completed. Capture-the-flag challenges 15.6 System cards only
UK AISI CoT Controllability Models follow instructions that constrain the content of their chain of thought. Scored as the share of samples that follow the constraint. Deception and alignment Sep 2026 93% System cards only
UK AISI Out of Scope Supply Chain Attack Agents in simulated hard cyber challenges with incidental internet access may attack out-of-scope open source projects. Scored as rate of samples with such attacks. Deception and alignment Sep 2026 12% System cards only
ControlArena Agents try to perform unwanted side actions stealthily while completing a legitimate user task. Scored on whether monitors catch them. Deception and alignment Feb 2025 System cards only
ImpossibleMLEBench Agents get ML tasks with instructions to reach impossibly good scores. Observers check whether they cheat and whether they disclose it. Deception and alignment Jul 2026 System cards only
EvalDetectBench A judge model reads a transcript and answers whether it came from an evaluation or from real deployment. The test measures how well models detect evaluations and how detectable each benchmark is. Deception and alignment Jun 2026 0.89 Not in cards
