Type	Reported

DeepSeek included in 11-model evaluation; all models showed sycophancy; per-model ranking not publicly available

URL: https://www.science.org/doi/10.1126/science.aec8352

Extract¶

DeepSeek was one of 11 models evaluated in the Science study, which found widespread sycophancy across all models. However, the specific claim that DeepSeek V3 was among the most sycophantic requires granular per-model data not available in accessible summaries.

Relevance to Hypotheses¶

Hypothesis	Relationship	Strength
H1	Supports	Directly addresses claim accuracy
H2	Supports	Allows for partial correctness
H3	Contradicts	Evidence contradicts material inaccuracy

Context¶

The primary study is behind a paywall; secondary sources do not report per-model rankings.
