FineFocus: Benchmarking and Improving Fine-Grained Text-to-Image Alignment via Paired Reinforcement Learning
ICML 2026poster
While recent autoregressive models have achieved text-to-image generation performance comparable to diffusion models, they significantly struggle with fine-grained semantic alignment. To rigorously evaluate this limitation, we introduce DeltaBench, a benchmark featuring paired prompts with subtle fi…
