📝 摘要(中文)

随着大型语言模型(LLMs)在各个领域的应用,确保其可靠性和安全性变得至关重要。这需要对模型进行严格的探测和审计,以维持其在实际应用中的有效性和可信度。本文介绍了“AuditLLM”,一种新颖的工具,旨在通过从单一问题派生多个探测来审计各种LLMs的性能。AuditLLM生成易于解释的结果,反映出模型在理解或性能上的一致性。该工具提供实时审计和批量审计两种模式,适用于研究人员和普通用户,增强了对LLMs生成响应能力的理解。

🔬 方法详解

问题定义:本文旨在解决大型语言模型在实际应用中的一致性和可靠性问题。现有方法缺乏有效的工具来系统性地审计这些模型的性能,导致潜在的偏见和幻觉未被及时发现。

核心思路:AuditLLM的核心思路是通过从单一输入问题生成多个不同表述的探测,来评估LLMs的响应一致性。这样的设计能够有效揭示模型在理解和生成方面的潜在问题。

技术框架:AuditLLM的整体架构包括两个主要模块:实时审计模式和批量审计模式。实时模式允许用户即时审计LLMs的响应,而批量模式则支持对多个查询进行综合分析。

关键创新:AuditLLM的主要创新在于其多探测审计方法,通过生成多样化的输入来检测模型的一致性,这与传统的单一输入审计方法有本质区别。

关键设计:在设计中,AuditLLM采用了易于解释的结果输出,能够清晰地反映模型的表现一致性。此外,工具的用户界面设计考虑了低技术门槛,使得研究人员和普通用户均能方便使用。

🎯 应用场景

AuditLLM的潜在应用领域包括教育、医疗、法律等多个行业,能够帮助用户更好地理解和评估LLMs的能力与局限性。通过系统性审计,用户可以识别模型中的偏见和不一致性,从而在实际应用中做出更为明智的决策。未来,该工具有望推动LLMs的安全性和可靠性研究,促进其在更广泛领域的应用。

📄 摘要(原文)

As Large Language Models (LLMs) are integrated into various sectors, ensuring their reliability and safety is crucial. This necessitates rigorous probing and auditing to maintain their effectiveness and trustworthiness in practical applications. Subjecting LLMs to varied iterations of a single query can unveil potential inconsistencies in their knowledge base or functional capacity. However, a tool for performing such audits with a easy to execute workflow, and low technical threshold is lacking. In this demo, we introduce ``AuditLLM,'' a novel tool designed to audit the performance of various LLMs in a methodical way. AuditLLM's primary function is to audit a given LLM by deploying multiple probes derived from a single question, thus detecting any inconsistencies in the model's comprehension or performance. A robust, reliable, and consistent LLM is expected to generate semantically similar responses to variably phrased versions of the same question. Building on this premise, AuditLLM generates easily interpretable results that reflect the LLM's consistency based on a single input question provided by the user. A certain level of inconsistency has been shown to be an indicator of potential bias, hallucinations, and other issues. One could then use the output of AuditLLM to further investigate issues with the aforementioned LLM. To facilitate demonstration and practical uses, AuditLLM offers two key modes: (1) Live mode which allows instant auditing of LLMs by analyzing responses to real-time queries; and (2) Batch mode which facilitates comprehensive LLM auditing by processing multiple queries at once for in-depth analysis. This tool is beneficial for both researchers and general users, as it enhances our understanding of LLMs' capabilities in generating responses, using a standardized auditing platform.
