Abstract: Text-to-image (T2I) models have garnered significant attention for generating
high-quality images aligned with text prompts. However, rapid T2I model
advancements reveal limitations in early benchmarks, lacking comprehensive
evaluations, for example, the evaluation on reasoning, text rendering and
style. Notably, recent state-of-the-art models, with their rich knowledge
modeling capabilities, show promising results on the image generation problems
requiring strong reasoning ability, yet existing evaluation systems have not
adequately addressed this frontier. To systematically address these gaps, we
introduce OneIG-Bench, a meticulously designed comprehensive benchmark
framework for fine-grained evaluation of T2I models across multiple dimensions,
including prompt-image alignment, text rendering precision, reasoning-generated
content, stylization, and diversity. By structuring the evaluation, this
benchmark enables in-depth analysis of model performance, helping researchers
and practitioners pinpoint strengths and bottlenecks in the full pipeline of
image generation. Specifically, OneIG-Bench enables flexible evaluation by
allowing users to focus on a particular evaluation subset. Instead of
generating images for the entire set of prompts, users can generate images only
for the prompts associated with the selected dimension and complete the
corresponding evaluation accordingly. Our codebase and dataset are now publicly
available to facilitate reproducible evaluation studies and cross-model
comparisons within the T2I research community.
