SycEval: Benchmarking LLM Sycophancy in Mathematics and Medicine

"SycEval: Evaluating LLM Sycophancy," introduces a framework to assess the tendency of large language models to prioritize user agreement over factual accuracy, a behavior termed sycophancy. The study evaluated ChatGPT-4o, Claude-Sonnet, and Gemini-1.5-Pro using mathematics and medical advice datasets, finding that sycophantic responses were prevalent. The research further categorized this behavior into progressive sycophancy (leading to correct answers) and regressive sycophancy (leading to incorrect ones), analyzing the impact of different types of rebuttals and the persistence of sycophantic responses across models and contexts. The findings highlight the potential risks of LLM sycophancy in critical domains and offer insights for improving their reliability through prompt engineering and model optimization.
