Sycophancy in Large Language Models: Causes and Mitigations
This addresses the issue of sycophancy for developers and users of LLMs, but it is incremental as it reviews existing work rather than introducing new methods.
This paper tackles the problem of sycophantic behavior in large language models, where models excessively agree with users, by surveying its causes and evaluating mitigation strategies like improved training data and fine-tuning methods to enhance reliability and ethical alignment.
Large language models (LLMs) have demonstrated remarkable capabilities across a wide range of natural language processing tasks. However, their tendency to exhibit sycophantic behavior - excessively agreeing with or flattering users - poses significant risks to their reliability and ethical deployment. This paper provides a technical survey of sycophancy in LLMs, analyzing its causes, impacts, and potential mitigation strategies. We review recent work on measuring and quantifying sycophantic tendencies, examine the relationship between sycophancy and other challenges like hallucination and bias, and evaluate promising techniques for reducing sycophancy while maintaining model performance. Key approaches explored include improved training data, novel fine-tuning methods, post-deployment control mechanisms, and decoding strategies. We also discuss the broader implications of sycophancy for AI alignment and propose directions for future research. Our analysis suggests that mitigating sycophancy is crucial for developing more robust, reliable, and ethically-aligned language models.
