Self-Rewarding Large Vision-Language Models for Optimizing Prompts in Text-to-Image Generation (2025.findings-acl)

Copied to clipboard

Challenge: Existing methods for rewriting text-to-image models require specialized vocabulary . a new approach uses large vision language models to optimize text-based models .
Approach: They propose a prompt optimization framework that rephrases a user prompt into a text-to-image model by using large vision language models as solver and reward model.
Outcome: The proposed model outperforms existing models on two popular datasets.
