 "lane": "defense",
 "kind": "benchmark",
 "summary": "Zou and colleagues (Gray Swan and collaborators; Anthropic describes the resulting benchmark as developed with the UK AI Security Institute) report a public red-teaming competition with 1.8 million prompt-injection attacks against 22 frontier agents in 44 deployment scenarios, producing over 60,000 successful policy violations. From these they build the Agent Red Teaming (ART) benchmark and find nearly all agents break within 10 to 100 queries for most behaviors, with high transfer and little correlation between robustness and model size or capability.",
 "whyItMatters": "The ART benchmark it created is used by labs, including in Anthropic system cards, to report agent prompt-injection robustness.",
