Research	R0057 — RLHF Yes-Men Claims v3
Run	2026-04-01
Claim	C008
Hypothesis	H1

Statement

DeepSeek V3 was specifically identified as among the most sycophantic

Status

Current: Plausible

Supporting Evidence

Evidence	Summary
SRC01-E01	DeepSeek included in 11-model evaluation; all models showed sycophancy; per-model ranking not publicly available

Contradicting Evidence

Evidence	Summary
—	No contradicting evidence found

Reasoning

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.

Relationship to Other Hypotheses

H1 represents full accuracy. H2 allows for partial correctness. H3 is eliminated by the evidence.
