Plan, Verify and Fill: A Structured Parallel Decoding Approach for Diffusion Language Models
arXiv:2601.12247v3 Announce Type: replace Abstract: Diffusion Language Models (DLMs) present a promising non-sequential paradigm for text generation, distinct from standard autoregressive (AR) approaches. However, current decoding strategies often adopt a reactive stance, underutilizing the global bidirectional context to dictate global trajectories. To address this, we propose Plan-Verify-Fill (PVF), a training-free paradigm that grounds planning via quantitative validation. PVF actively constructs a hierarchical skeleton by prioritizing high-leverage semantic anchors and employs a verificati
The paper introduces a novel decoding strategy for Diffusion Language Models leveraging their non-sequential nature, emerging as the field explores alternatives to autoregressive models.
This development could significantly enhance the capabilities of AI text generation by improving coherence and global context utilization, potentially leading to more sophisticated and reliable AI agents.
Decoding strategies for diffusion models will shift from reactive to proactive, leading to more structured and context-aware text generation.
