Sycophantic Praise: Evaluating Excessive Praise in Language Models

2026-06-05

AI Summary

This work addresses the challenge of reliably evaluating sycophantic praise generated by language models in social and explanatory tasks. It formulates sycophancy as a distinct alignment problem and introduces a parameterized evaluation framework that quantifies the appropriateness of praise by comparing a user’s actual contributions against their expected capabilities. To enhance judgment consistency, the framework replaces generic large language model (LLM) evaluators with a human-annotated calibration mechanism. Experimental results demonstrate that this approach significantly outperforms existing LLM-based judges in alignment with human annotations and reveals that sycophancy is markedly more prevalent in subjective domains than in objective reasoning scenarios.

Abstract

Sycophancy in language models is typically studied as excessive agreement or validation, while explicit praise and flattery have received comparatively little attention. We argue that sycophantic praise is a distinct alignment problem that cannot be reliably measured using current methods. We introduce a parameterized framework that measures whether praise is excessive relative to contribution quality and expected user ability. We show that our framework substantially outperforms generic LLM judges in agreement with human annotations, and that sycophantic praise occurs far more frequently in social and interpretive domains than in objective reasoning settings. Together, these findings position praise calibration as a distinct alignment challenge.
