arXiv:2602.18176v3 Announce Type: replace Abstract: Masked Diffusion Models (MDMs) enable flexible decoding orders, yet existing samplers remain largely greedy, selecting locally certain tokens without accounting for their downstream effects. We show that this myopia can increase cumulative uncertainty and lead to suboptimal generation. To address this, we propose the **Info-Gain Sampler**, a training-free decoding method that uses the bidirectional structure of MDMs to balance immediate uncertainty with the information gained over remaining masked positions.

The continuous improvement in AI model capabilities and efficiency drives research into advanced sampling methods for generative AI, like MDMs, to overcome current limitations.
Improved sampling methods directly enhance the quality and reliability of AI-generated content across various applications, significantly impacting model performance and usability.
This new sampling technique improves the efficiency and output quality of masked diffusion models, potentially reducing computational costs and generation errors for inference.
