However, evaluating these models remains a significant challenge. Existing benchmarks exhibit critical limitations: 1) insufficient diversity and comprehensiveness in subject images, 2) inadequate granularity in assessing model performance across different subject difficulty levels and prompt scenarios, and 3) a profound lack of actionable insights and diagnostic guidance for subsequent model refinement. To address these limitations, we propose DSH-Bench, a comprehensive benchmark that enables systematic multi-perspective analysis of subject-driven T2I models through four principal innovations: 1) a hierarchical taxonomy sampling mechanism ensuring comprehensive subject representation across 58 fine-grained categories, 2) an innovative classification scheme categorizing both subject difficulty level and prompt scenario for granular capability assessment, 3) a novel Subject Identity Consistency Score (SICS) metric demonstrating a 9.4\\% higher correlation with human evaluation compared to existing measures in quantifying subject preservation, and 4) a comprehensive set of diagnostic insights derived from the benchmark, offering critical guidance for optimizing future model training paradigms and data construction strategies. Through an extensive empirical evaluation of 19 leading models, DSH-Bench uncovers previously obscured limitations in current approaches, establishing concrete directions for future research and development.</summary>\n    <category scheme='http://arxiv.org/schemas/atom' term='cs.CV'/>\n    <category scheme='http://arxiv.org/schemas/atom' term='cs.AI'/>\n    <published>2026-03-09T08:30:28Z</published>\n    <arxiv:primary_category term='cs.CV'/>\n    <author>\n      <name>Zhenyu Hu</name>\n    </author>\n    <author>\n      <name>Qing Wang</name>\n    </author>\n    <author>\n      <name>Te Cao</name>\n    </author>\n    <author>\n      <name>Luo Liao</name>\n    </author>\n    <author>\n      <name>Longfei Lu</name>\n    </author>\n    <author>\n      <name>Liqun Liu</name>\n    </author>\n    <author>\n      <name>Shuang Li</name>\n    </author>\n    <author>\n      <name>Hang Chen</name>\n    </author>\n    <author>\n      <name>Mengge Xue</name>\n    </author>\n    <author>\n      <name>Yuan Chen</name>\n    </author>\n    <author>\n      <name>Chao Deng</name>\n    </author>\n    <author>\n      <name>Peng Shu</name>\n    </author>\n    <author>\n      <name>Huan Yu</name>\n    </author>\n    <author>\n      <name>Jie Jiang</name>\n    </author>\n  </entry>"
