Translated data: The research team from Fudan University and Renmin University of China, known as the Chat Suzumiya Haruhi collaboration, has emphasized the critical importance of character fidelity in AI role-playing, achieving a trait fidelity rate of 82.8%. The study utilized the Big Five personality traits and MBTI tests, employing LLM-guided questionnaires to comprehensively assess the personalities of AI characters. The proposed interview-style personality testing framework offers a novel approach for evaluating role-playing AI, with experimental results showing a fidelity rate of 82.8% in both the Big Five and MBTI tests. The researchers call for in-depth studies on the impact of different base models, revealing some challenges and limitations in current technology.
