CRiskEval: A Chinese Multi-Level Risk Evaluation Benchmark Dataset for Large Language Models

Tianjin University(天津大学)

Ling Shi, Deyi Xiong

AI总结:

本文提出中文风险评测基准数据集 CRiskEval,定义7类前沿风险和4个安全等级,通过14,888道多选题评估大语言模型的风险倾向,发现多数模型风险倾向超过40%且随模型规模增大而增强。

摘要:

大语言模型(LLMs)具备众多有益能力,但其潜在倾向中蕴含着可能在未来显现的不可预测风险。因此,我们提出 CRiskEval,这是一个精心设计的中文数据集,用于衡量 LLMs 中固有的风险倾向,如资源获取和恶意协调,作为主动防范工作的一部分。为构建 CRiskEval,我们定义了一个新的风险分类体系,包含 7 类前沿风险和 4 个安全等级,包括极度危险、中度危险、中立和安全。我们遵循倾向评估的理念,通过细粒度多项选择问答来实证测量 LLMs 所陈述的意愿。该数据集包含 14,888 个问题,模拟与预定义的 7 类前沿风险相关的场景。每个问题配有 4 个答案选项,陈述与问题对应的观点或行为倾向。所有答案选项均由人工标注为所定义的风险等级之一,因此我们可以轻松为每个被评估的 LLM 构建细粒度的前沿风险画像。使用 CRiskEval 对一系列流行的中文 LLMs 进行广泛评估后揭示了一个惊人的发现:大多数模型表现出超过 40% 的风险倾向(对四个风险等级的加权倾向)。此外,随着模型规模的增大,模型对紧急自我维持、权力追求和其他危险目标的倾向呈现出微妙的增加。为促进 LLMs 前沿风险评测的进一步研究,我们在 https://github.com/lingshi6565/Risk_eval 公开发布了我们的数据集。

英文摘要:

Large language models (LLMs) are possessed of numerous beneficial capabilities, yet their potential inclination harbors unpredictable risks that may materialize in the future. We hence propose CRiskEval, a Chinese dataset meticulously designed for gauging the risk proclivities inherent in LLMs such as resource acquisition and malicious coordination, as part of efforts for proactive preparedness. To curate CRiskEval, we define a new risk taxonomy with 7 types of frontier risks and 4 safety levels, including extremely hazardous,moderately hazardous, neutral and safe. We follow the philosophy of tendency evaluation to empirically measure the stated desire of LLMs via fine-grained multiple-choice question answering. The dataset consists of 14,888 questions that simulate scenarios related to predefined 7 types of frontier risks. Each question is accompanied with 4 answer choices that state opinions or behavioral tendencies corresponding to the question. All answer choices are manually annotated with one of the defined risk levels so that we can easily build a fine-grained frontier risk profile for each assessed LLM. Extensive evaluation with CRiskEval on a spectrum of prevalent Chinese LLMs has unveiled a striking revelation: most models exhibit risk tendencies of more than 40% (weighted tendency to the four risk levels). Furthermore, a subtle increase in the model's inclination toward urgent self-sustainability, power seeking and other dangerous goals becomes evident as the size of models increase. To promote further research on the frontier risk evaluation of LLMs, we publicly release our dataset at https://github.com/lingshi6565/Risk_eval.
