RangeSWA is a training‑free method designed to improve length extrapolation in continuous diffusion language models. It combines local sliding‑window attention, remote block summaries, and dynamic content retrieval to maintain local detail while accessing long‑range context. The approach also includes positional remapping, conditioning attention correction, and denoising‑stage‑adaptive window scheduling to mitigate generation degradation, resulting in lower perplexity and fewer repetitions in long‑text generation.

The paper introduces Seq-Drifting, a new framework that enables diffusion language models to generate an entire text sequence in a single forward pass. By applying a drift field to continuous token representations, the model learns a direct mapping from Gaussian noise to text, using attraction to guide outputs toward contextually plausible tokens and repulsion to prevent repetition and collapse. Experiments show that Seq-Drifting achieves a perplexity of 36.01 on LM1B and performs competitively in unconditional, conditional, translation, summarization, and reasoning tasks.

The paper introduces a survival-guided length control method for diffusion language models (DLMs), framing length selection as a discrete-time survival problem over the end-of-sequence token. This training‑free, plug‑in length predictor can be added to any existing DLM and reduces unnecessary denoising steps. Experiments on reasoning and code‑generation benchmarks show up to a seven‑fold speedup in inference while maintaining task accuracy, and reveal that predicted lengths vary significantly even within the same dataset, affecting model performance.

arXiv:2511. 21338v2 Announce Type: replace Abstract: Masked Diffusion Language Models (MDLMs) have recently emerged as a promising alternative to Autoregressive Language Models (ARLMs), leveraging a denoising objective that, in principle, should enable more uniform context utilisation.
arXiv:2602. 11133v2 Announce Type: replace Abstract: Diffusion language models generate text through iterative refinement, a process that is often computationally inefficient because many tokens reach stability long before the final denoising step.
The paper introduces Representation-based Masked Diffusion Model (RMDM), a new framework for language modeling that improves upon existing Masked Diffusion Models by incorporating global semantic guidance. RMDM encodes text into a continuous semantic space with a pretrained encoder, normalizes this representation to a Gaussian prior via an invertible transformation, and then trains a masked diffusion model conditioned on this latent representation to coordinate parallel token updates. Experiments show that RMDM yields higher generation quality, especially when using aggressive few‑step sampling.
