Evaluating the performance of general purpose large language models in identifying human facial emotions
This study evaluated the ability of three leading large language models (LLMs)—GPT-4o, Gemini 2.0 Experimental, and Claude 3.5 Sonnet—to recognize human facial expressions from the NimStim dataset. Findings indicate that GPT-4o and Gemini 2.0 Experimental achieved high agreement with ground truth, comparable to or exceeding human performance, particularly for calm/neutral and surprise. Claude 3.5 Sonnet showed lower overall reliability. A key challenge identified across models was the misclassification of 'fear'. These results highlight the growing socioemotional competence of LLMs and their potential for healthcare applications, while also emphasizing areas needing further development and careful contextual application.

LLM Performance Benchmark
GPT-4o demonstrated 'almost perfect' agreement with ground truth, matching or exceeding human raters on several emotions, particularly calm/neutral and surprise. This underscores its advanced capability in nuanced socioemotional understanding.
0.83 GPT-4o Overall KappaChallenges in Fear Recognition
A notable limitation across all evaluated models was the difficulty in accurately recognizing 'fear'. GPT-4o misclassified fear as 'surprise' 52.50% of the time, highlighting a key area for model improvement in complex emotional interpretation.

Human-LLM Agreement Parity
The 95% confidence intervals for Kappa often overlapped between top LLMs (GPT-4o, Gemini) and human observers in the NimStim dataset, indicating comparable levels of reliability. This suggests LLMs are nearing human-level interpretive capabilities in certain contexts.
Human-LLM Comparable ReliabilityApplication in Behavioral Healthcare
LLMs capable of interpreting subtle facial expressions offer significant promise for behavioral healthcare. Imagine a system where real-time analysis of patient expressions during virtual consultations could flag potential indicators of mental health conditions like depression or anxiety. This could lead to earlier diagnosis, real-time monitoring, and adaptive interventions, revolutionizing how care is delivered and supporting clinicians in identifying nuanced emotional cues that might otherwise be missed. The ability to process diverse visual stimuli and provide validated ground truth labels makes these AI-powered systems a powerful tool for enhancing patient outcomes.
