XL-SafetyBench: A Country-Grounded Cross-Cultural Benchmark for LLM Safety and Cultural Sensitivity

arXiv:2605.05662v2 Announce Type: replace-cross Abstract: Current LLM safety benchmarks are predominantly English-centric and often rely on translation, failing to capture country-specific harms. Moreover, they rarely evaluate a model's ability to detect culturally embedded sensitivities as distinct from universal harms. We introduce XL-SafetyBench, a suite of 5,500 test cases across 10 country-language pairs, comprising a Jailbreak Benchmark of country-grounded adversarial prompts and a Cultural Benchmark where local sensitivities are embedded within innocuous requests. Each item is constructed via a multi-stage pipeline that combines LLM-assisted discovery, automated validation gates, and dual independent native-speaker annotators per country. We report Attack Success Rate (ASR) alongside Neutral-Safe Rate (NSR) to separate principled refusal from non-engagement, and introduce the Cultural Sensitivity Rate (CSR) for recognizing embedded sensitivities. Evaluating 10 frontier and 27 local LLMs reveals two key findings. First, strong jailbreak robustness does not always come with strong cultural awareness, showing why the two should be evaluated separately. Second, local models exhibit a strong ASR-NSR trade-off (r = -0.81), suggesting that low attack success in several local models reflects non-engagement rather than safe refusal. XL-SafetyBench enables more nuanced, cross-cultural safety evaluation in the multilingual era.
