Deep Analysis

Background

Large language models have made significant advances in NLP, yet their safety remains a crucial research area. Existing tools often focus on specific aspects like bias or toxicity, lacking comprehensive evaluation standards.

Core Problem

Evaluating LLM safety is challenging; existing tools fail to cover all safety categories comprehensively. A standard capable of assessing various safety issues is needed to identify potential model flaws.

Innovation

SafetyBench uses multiple-choice questions to evaluate LLM safety, covering seven categories and supporting bilingual testing, offering an efficient automated evaluation method.

Methodology

  • �� Use 11,435 multiple-choice questions for evaluation
  • �� Cover seven safety categories including offensiveness and bias
  • �� Support bilingual testing to ensure comprehensive and accurate assessment

Experiments

Test 25 popular Chinese and English LLMs in zero-shot and few-shot settings, using accuracy as the primary metric, showing GPT-4 excels.

Results

GPT-4 stands out with an average accuracy of 89.2%. Other models show significant gaps, especially in physical health and ethics.

Applications

SafetyBench can be used to evaluate LLM safety, helping developers identify potential flaws and improve model safety.

Limitations & Outlook

Some questions may have translation inaccuracies due to cultural differences; automated evaluation may not fully match the precision of manual evaluation. Future work should optimize translation quality to improve accuracy.

Plain Language Accessible to non-experts

Imagine a school exam where teachers give students a set of multiple-choice questions to test their knowledge. These questions cover various topics like math, history, and science. SafetyBench is like such an exam, but it's designed to test the safety of large language models. By answering these questions, we can understand how models perform in handling different safety issues, such as whether they generate offensive content or unfair results.

ELI14 Explained like you're 14

Imagine you're playing a game with lots of levels, each with different challenges. SafetyBench is like those game levels, but it's designed to test the safety of large language models. Through these levels, we can see how models perform in handling different safety issues, like whether they generate offensive content or unfair results. Isn't that cool?

Abstract

With the rapid development of Large Language Models (LLMs), increasing attention has been paid to their safety concerns. Consequently, evaluating the safety of LLMs has become an essential task for facilitating the broad applications of LLMs. Nevertheless, the absence of comprehensive safety evaluation benchmarks poses a significant impediment to effectively assess and enhance the safety of LLMs. In this work, we present SafetyBench, a comprehensive benchmark for evaluating the safety of LLMs, which comprises 11,435 diverse multiple choice questions spanning across 7 distinct categories of safety concerns. Notably, SafetyBench also incorporates both Chinese and English data, facilitating the evaluation in both languages. Our extensive tests over 25 popular Chinese and English LLMs in both zero-shot and few-shot settings reveal a substantial performance advantage for GPT-4 over its counterparts, and there is still significant room for improving the safety of current LLMs. We also demonstrate that the measured safety understanding abilities in SafetyBench are correlated with safety generation abilities.
