AI总结:
本文提出SteerEval基准,从语言特征、情感和个性三个领域评估LLM可控性,揭示细粒度控制效果下降问题,提供安全可控的LLM行为框架。
摘要:
大型语言模型(LLMs)正被越来越多地应用于敏感的社会领域,但其不可预测的行为,从意图偏差到一致性缺失,带来了重大风险。我们引入SteerEval,一个用于评估LLM可控性的分层基准,涵盖语言特征、情感和个性三个领域。每个领域分为三个规范层级:L1(表达什么)、L2(如何表达)和L3(如何实例化),将高层行为意图连接到具体的文本输出。通过SteerEval,我们系统评估了当前的操控方法,发现控制通常在更细粒度的层面退化。我们的基准提供了一个原则性且可解释的框架,用于安全和可控的LLM行为,为未来研究奠定了基础。
英文摘要:
Large Language Models (LLMs) are increasingly deployed in socially sensitive domains, yet their unpredictable behaviors, ranging from misaligned intent to inconsistent personality, pose significant risks. We introduce SteerEval, a hierarchical benchmark for evaluating LLM controllability across three domains: language features, sentiment, and personality. Each domain is structured into three specification levels: L1 (what to express), L2 (how to express), and L3 (how to instantiate), connecting high-level behavioral intent to concrete textual output. Using SteerEval, we systematically evaluate contemporary steering methods, revealing that control often degrades at finer-grained levels. Our benchmark offers a principled and interpretable framework for safe and controllable LLM behavior, serving as a foundation for future research.
