arXiv:2605.29607v1 Announce Type: new Abstract: Masked diffusion language models (MDLMs) enable parallel decoding by predicting all masked positions at each denoising step, yet existing training-free samplers usually decide which positions to commit at token-level granularity. We revisit this granularity and observe that reliable predictions often emerge as contiguous high-confidence spans, suggesting that the unit of parallel commitment can be larger than a single token. We first group adjacent high-confidence candidates into confidence-induced clusters (CICs) as span-level update units. We t
This research addresses fundamental limitations in current Masked Diffusion Language Model (MDLM) decoding strategies, specifically the inefficiency of token-level commitments, which has become a bottleneck for wider application.
Improved parallel decoding for MDLMs significantly boosts their efficiency, making them faster and more scalable, which is critical for their deployment in various AI applications.
The shift from token-level to cluster-level attention-guided parallel decoding allows for more coherent and rapid text generation, potentially redefining the efficiency frontier for diffusion-based language models.
