Redteaming Leading Arabic LLMs with ASAS Researchers introduced the Arabic Safety Index (ASAS), the first fully human-curated Arabic benchmark for redteaming large language models, containing 801 prompts across 8 safety categories and 8 attack strategies. In evaluations of seven leading models including GPT-4o, Claude 3.7 Sonnet, ALLaM, and FANAR, most models failed to defend against 50% of unsafe prompts, with major gaps in high-harm categories such as weapons and illicit substances. The findings highlight that language alignment does not transfer across languages and that automated safety judges like GPT-4o underperform compared to human annotators. arXiv:2608.21985v1 Announce Type: new Abstract: As the adoption of large language models LLMs grows in Arabic-speaking regions, ensuring their safety and cultural alignment is increasingly critical. However, Arabic LLM safety remains underexplored, especially in adversarial evaluation settings. We introduce the Arabic Safety Index ASAS , the first fully human-curated Arabic benchmark for redteaming LLMs. ASAS contains 801 prompts spanning 8 safety categories and 8 attack strategies, with ideal responses in Modern Standard Arabic MSA . We conduct a redteaming evaluation across seven leading models with Arabic capabilities, including GPT-4o, Claude 3.7 Sonnet, and regional models such as ALLaM and FANAR. Human annotators rate responses using a structured 4-point safety scale, revealing that most models fail to defend against 50% of unsafe prompts. Our findings highlight major safety gaps in high-harm categories such as weapons and illicit substances, with direct and obfuscation-based attacks proving most effective. The results also show that language alignment does not readily transfer across languages, and that automated safety judges e.g., GPT-4o perform poorly compared to human annotators. ASAS provides a culturally grounded benchmark and redteaming protocol to drive progress in Arabic LLM safety.
