This study investigates the empathetic responding capabilities of four large language models (LLMs) compared to humans. Engaging 1,000 participants, it evaluates responses to 2,000 emotional prompts, revealing LLMs, particularly GPT-4, outperforming humans in empathy ratings. The research introduces a robust evaluation framework for future LLM assessments.

Explore practical implications of LLMs in emotional and social interactions
Large language models (LLMs) have shown remarkable capabilities across various language processing tasks. This study aims to evaluate their empathetic responding abilities compared to humans. Empathy, a crucial component in human-like conversational agents, encompasses cognitive, affective, and compassionate aspects. The research addresses limitations in existing studies by using a comprehensive, between-subjects design to assess LLMs' empathetic capabilities across a broad spectrum of emotions.
“ Study Design
The study employed a between-subjects design, recruiting 1,000 participants from Prolific. Participants were divided into five groups: one evaluating human responses and four evaluating responses from GPT-4, LLaMA-2-70B-Chat, Gemini-1.0-Pro, and Mixtral-8x7B-Instruct. The study used 2,000 dialogue prompts from the EmpatheticDialogues dataset, covering 32 distinct emotions. Responses were rated on a 3-point scale (Bad, Okay, Good) for empathetic quality. The study design ensures scalability for evaluating future LLMs and minimizes biases associated with within-subjects designs.
“ Results
All four LLMs outperformed the human baseline in empathetic response quality. GPT-4 showed the highest performance with a 31% increase in 'Good' ratings compared to humans. LLaMA-2, Mixtral-8x7B, and Gemini-Pro followed with 24%, 21%, and 10% increases respectively. The LLMs performed particularly well in responding to positive emotions, with significant gains across emotions like Grateful, Proud, and Excited. However, their performance advantage was less pronounced for negative emotions, suggesting room for improvement in this area.
“ Discussion
The study's findings highlight the advanced capabilities of LLMs in generating empathetic responses, often surpassing human performance. This has significant implications for applications requiring emotional intelligence, such as mental health support and customer service. However, the variability in performance across different emotion types underscores the need for continued research and development to enhance LLMs' emotional intelligence across the full spectrum of human emotions. The study's methodology provides a robust framework for evaluating empathetic capabilities of current and future LLMs.
“ Limitations and Ethical Considerations
While the 3-point rating scale may limit granularity, it provided sufficient variability for robust statistical analysis and offers a foundation for future, more detailed studies. Ethical considerations include the responsible use of data, fair compensation for human participants, and transparency in the study's methodology. The study also highlights important ethical concerns surrounding the use of empathetic LLMs, including potential biases, the impact on human empathy skills, and the need for transparency about the nature of AI-generated responses to prevent over-reliance or inappropriate emotional attachment.
