## Summary

The paper introduces SatisDive, a training-free inference-time method for text-to-image generation that balances reward and diversity by treating generation as a satisficing problem. It ensures each image meets a reward floor while the batch satisfies a diversity cutoff. On the Pick-a-Pic dataset, SatisDive improves worst-candidate reward over FK steering by up to 0.43 when using FLUX.1-dev as the base model and HPSv3 as the reward model, and by up to 0.70 with SANA-1.6B and ImageReward. The method's satisfaction-diversity curve Pareto-dominates FK steering's across overlapping DreamSim ranges.

## Key points

- SatisDive is a training-free inference-time method for text-to-image generation
- It improves worst-candidate reward by up to 0.43 with FLUX.1-dev and HPSv3 on Pick-a-Pic
- It improves worst-candidate reward by up to 0.70 with SANA-1.6B and ImageReward on Pick-a-Pic

## Why it matters

The method offers a principled way to balance image quality and diversity in text-to-image generation, potentially improving user control and output reliability in generative AI systems.
