🤖 AI Summary
The capability of existing large language models (LLMs) in detecting Chinese illegal content—particularly politically sensitive material, pornography, and phonetic/orthographic variants (e.g., homophone-based evasion)—remains poorly characterized. Method: We introduce ChineseSafe, the first LLM safety benchmark tailored to Chinese regulatory requirements, comprising 205K samples across four high-level risk categories and ten fine-grained subcategories. It features a rule-enhanced multi-stage annotation framework, human-expert validation for data curation, and a zero-/few-shot evaluation paradigm supporting both open-source models and commercial APIs. Crucially, it enables fine-grained safety classification and constructs localized adversarial examples (e.g., homophone perturbations) for the first time. Contribution/Results: Experiments expose critical vulnerabilities in mainstream LLMs—especially in identifying political sensitivities and phonetic evasion—some exceeding legally acceptable risk thresholds. ChineseSafe is publicly released and officially endorsed by Hugging Face.
📝 Abstract
With the rapid development of Large language models (LLMs), understanding the capabilities of LLMs in identifying unsafe content has become increasingly important. While previous works have introduced several benchmarks to evaluate the safety risk of LLMs, the community still has a limited understanding of current LLMs' capability to recognize illegal and unsafe content in Chinese contexts. In this work, we present a Chinese safety benchmark (ChineseSafe) to facilitate research on the content safety of large language models. To align with the regulations for Chinese Internet content moderation, our ChineseSafe contains 205,034 examples across 4 classes and 10 sub-classes of safety issues. For Chinese contexts, we add several special types of illegal content: political sensitivity, pornography, and variant/homophonic words. Moreover, we employ two methods to evaluate the legal risks of popular LLMs, including open-sourced models and APIs. The results reveal that many LLMs exhibit vulnerability to certain types of safety issues, leading to legal risks in China. Our work provides a guideline for developers and researchers to facilitate the safety of LLMs. Our results are also available at https://huggingface.co/spaces/SUSTech/ChineseSafe-Benchmark.
