Is Safety Standard Same for Everyone? User-Specific Safety Evaluation of Large Language Models
This addresses a critical gap in safe LLM use by introducing a benchmark for user-specific safety evaluation, though it is incremental as it builds on existing safety concerns.
The paper tackles the problem of evaluating large language model (LLM) safety based on user-specific standards rather than general ones, revealing that 20 widely used LLMs fail to act safely under these conditions.
As the use of large language model (LLM) agents continues to grow, their safety vulnerabilities have become increasingly evident. Extensive benchmarks evaluate various aspects of LLM safety by defining the safety relying heavily on general standards, overlooking user-specific standards. However, safety standards for LLM may vary based on a user-specific profiles rather than being universally consistent across all users. This raises a critical research question: Do LLM agents act safely when considering user-specific safety standards? Despite its importance for safe LLM use, no benchmark datasets currently exist to evaluate the user-specific safety of LLMs. To address this gap, we introduce U-SafeBench, a benchmark designed to assess user-specific aspect of LLM safety. Our evaluation of 20 widely used LLMs reveals current LLMs fail to act safely when considering user-specific safety standards, marking a new discovery in this field. To address this vulnerability, we propose a simple remedy based on chain-of-thought, demonstrating its effectiveness in improving user-specific safety.
