Profile-LLM: Dynamic Profile Optimization for Realistic Personality Expression in LLMs

arXiv — cs.CLWednesday, November 26, 2025 at 5:00:00 AM
  • A new framework called PersonaPulse has been introduced to optimize prompts for Large Language Models (LLMs), enhancing their ability to express realistic personality traits. This approach iteratively refines role-play prompts while using a situational response benchmark for evaluation, demonstrating improved performance over previous methods based on psychological personality descriptions.
  • The development of PersonaPulse is significant as it addresses the limitations of earlier studies in maximizing personality expression in LLMs, potentially leading to more engaging and enjoyable interactions between users and AI systems. This advancement could enhance user experience across various applications of LLMs.
  • This innovation reflects a broader trend in AI research towards improving personalization and emotional expression in LLMs. As the field evolves, there is an increasing focus on creating more agentic models that can reason and interact effectively, while also addressing challenges related to alignment with human values and the robustness of AI systems against adversarial inputs.
