aiqbench analysis

UltraText Bench introduces a rigorous bilingual evaluation framework specifically designed to test the limits of image generators in rendering dense, multi-region text with high fidelity and legibility. By leveraging the Q-Judger vision-language model for automated assessment across 24 configurations, this benchmark exposes critical trade-offs between clarity and accuracy in complex visual scenes. It represents a significant step forward in establishing standardized metrics for evaluating advanced generative capabilities beyond simple short-string reproduction.

UltraText Bench: A Comprehensive Bilingual Benchmark for Evaluating Visual Text Rendering in Image Generation

arXiv2 min read

arXiv:2610.09823v1 Announce Type: cross Abstract: Dense visual text requires image generators to reproduce long strings across multiple regions with correct placement and legibility. As short-string rendering improves, evaluation must test sustained performance across more demanding scenes. We introduce UltraText Bench, a bilingual benchmark for prompt-only generation of dense visual text. It contains 432 prompts spanning 24 real-world scene categories and three difficulty levels, split equally between English and Chinese. Each human-reviewed prompt supplies exact strings for four to twelve text regions, paired with structured references for their content, placement, and visual attributes. We use the Q-Judger vision-language model to assess each image against the complete reference, reporting text fidelity, text clarity, spatial quality, and scene quality. Across 24 model configurations, these dimensions reveal different strengths: Z-Image-Turbo gains 3.81 clarity points over Z-Image-Base while losing 14.76 fidelity points under the reported settings. Performance also varies with workload; Qwen-Image-2512's English composite falls from 86.50 at L1 to 42.86 at L3. Ten participants took part in human evaluation of the automatic scores.
