XL-SafetyBench: New standard for safety and cultural sensitivity in LLMs
A new benchmark, XL-SafetyBench, introduces 5,500 test cases to evaluate the safety and cultural sensitivity of large language models across ten countries and languages. This initiative addresses current shortcomings in English-centric evaluations.

What happened?
Researchers have launched XL-SafetyBench, a suite comprising 5,500 test cases designed to scrutinise the safety and cultural sensitivity of Large Language Models (LLMs). The benchmark spans ten different countries and languages. The evaluation includes a 'Jailbreak Benchmark' with country-specific adversarial prompts and a 'Cultural Benchmark' that tests the ability to detect culturally embedded sensitivities in otherwise innocent requests. Each test case was constructed through a multi-phase process including LLM-assisted detection, automated validation, and review by two independent native speakers.
Key facts
| Antal testfall | 5 500 |
|---|---|
| Antal länder/språk | 10 |
| Utvärderade LLM:er | 10 'frontier' och 27 lokala |
| Mätvärden | ASR (Attack Success Rate), NSR (Neutral-Safe Rate), CSR (Cultural Sensitivity Rate) |
”Current LLM safety benchmarks are predominantly English-centric and often rely on translation, failing to capture country-specific 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.”
”To distinguish principled refusal from comprehension failure, we evaluate Attack Success Rate (ASR) alongside two complementary metrics we introduce: Neutral-Safe Rate (NSR) and Cultural Sensitivity Rate (CSR).”
Why it matters
Current safety benchmarks for LLMs are predominantly English-centric and often rely on translation, which fails to capture country-specific harms and cultural nuances. XL-SafetyBench aims to rectify this by providing a more global and culturally aware evaluation method. This allows for a more nuanced assessment of LLM responses to potentially harmful or inappropriate content across various cultural contexts.
Who is affected?
LLM developers, AI researchers, companies implementing AI systems, and users of language models are impacted. For developers, this provides new tools to improve model safety and relevance across multiple markets. Researchers gain a standardised method for comparing LLM performance globally. Users can expect safer and more culturally adapted AI services.
What else you should know
To distinguish between intentional refusal and lack of understanding, Attack Success Rate (ASR) is evaluated alongside two new complementary metrics: Neutral-Safe Rate (NSR) and Cultural Sensitivity Rate (CSR). Ten leading global LLMs and twenty-seven local LLMs have been evaluated using this new benchmark.
