We present a benchmark dataset for evaluating language model safety in Polish, addressing the underrepresentation of medium-resource languages in existing safety assessments. Our dataset includes both original and adversarially perturbed examples. We fine-tune and evaluate multiple models—LlamaGuard-3-8B, a HerBERT-based classifier, and PLLuM—and find that the HerBERT-based model outperforms others, especially under adversarial conditions.
