Researchers have introduced Arena-T2I Hard, a new benchmark designed to evaluate the faithfulness of text-to-image models, particularly for complex, multi-faceted prompts. This benchmark, derived from real user logs, includes approximately 30 decomposed constraints per prompt, addressing issues like spatial relationships, stylistic nuances, and text rendering, which are often missed by simpler benchmarks. The study found that top-tier systems still exhibit significant performance gaps on this harder benchmark, and that aesthetic preferences in public arenas do not necessarily correlate with fine-grained prompt adherence. To improve faithfulness, a dependency-aware checklist reward mechanism was proposed, which decomposes prompts into a directed acyclic graph of questions, providing a more granular training signal. This approach, combined with aesthetic rewards, demonstrated a better trade-off between faithfulness and aesthetics on models like SD3.5-Medium and FLUX.1-dev compared to simpler reward strategies.
