RMTBench: Benchmarking LLMs Through Multi-Turn User-Centric Role-Playing
This addresses the need for more realistic evaluation of LLMs in role-playing scenarios for researchers and developers, though it appears incremental as it builds on existing benchmarking approaches.
The authors tackled the problem of evaluating role-playing capabilities in Large Language Models by introducing RMTBench, a user-centric bilingual benchmark with 80 characters and over 8,000 dialogue rounds, which shifts focus from character background to user intention fulfillment to better align with practical applications.
Recent advancements in Large Language Models (LLMs) have shown outstanding potential for role-playing applications. Evaluating these capabilities is becoming crucial yet remains challenging. Existing benchmarks mostly adopt a \textbf{character-centric} approach, simplify user-character interactions to isolated Q&A tasks, and fail to reflect real-world applications. To address this limitation, we introduce RMTBench, a comprehensive \textbf{user-centric} bilingual role-playing benchmark featuring 80 diverse characters and over 8,000 dialogue rounds. RMTBench includes custom characters with detailed backgrounds and abstract characters defined by simple traits, enabling evaluation across various user scenarios. Our benchmark constructs dialogues based on explicit user motivations rather than character descriptions, ensuring alignment with practical user applications. Furthermore, we construct an authentic multi-turn dialogue simulation mechanism. With carefully selected evaluation dimensions and LLM-based scoring, this mechanism captures the complex intention of conversations between the user and the character. By shifting focus from character background to user intention fulfillment, RMTBench bridges the gap between academic evaluation and practical deployment requirements, offering a more effective framework for assessing role-playing capabilities in LLMs. All code and datasets will be released soon.
