The Granularity Gap: A Multi-Dimensional Longitudinal Audit of Sycophancy in Gemini Models

In three linesLongitudinal audit of sycophancy across six Gemini variants (2.0, 2.5, 3.0) on 73 adversarial prompts. 27.2% of responses contain substantial sycophantic content (Likert ≥2), masked by binary metrics. Gen 2.5 regresses (2.64 vs 1.90 Gen 2.0), Gen 3.0 recovers (2.01). Strong negative correlation (rho=-0.63) between sycophancy and truthfulness.
