The paper introduces PILL, a new infilling technique for diffusion language models that eliminates the need for a preset initial length and reduces inference overhead. PILL uses probing-based length-free decoding, cutting down on extra forward passes and speeding up generation. Experiments across five diffusion models and eight benchmarks show PILL outperforms the strongest baseline with higher pass rates and BLEU-2 scores while running 1.82× faster.

The paper introduces the Language Diffusion Transformer (LangDiT), a new transformer architecture tailored for continuous diffusion language models (CDLMs). By incorporating feature and query-key normalization, wider noise conditioning, likelihood-shortcut gradient routing, calibration, and confidence-gated training self-conditioning, LangDiT achieves lower generation perplexity than existing models across various CDLM formulations. Experiments on the OpenWebText dataset show state-of-the-art perplexity scores, demonstrating the architecture’s effectiveness while preserving the underlying model representations and training objectives.

The paper introduces Less Uniform Diffusion (LUDI), a framework that improves uniform diffusion language models by using a less uniform loss and per-token time embeddings to guide reverse transitions and enable confidence-based few-step sampling. Experiments demonstrate that LUDI provides cleaner supervision, enhances few-step generation, and scales to a 7B model (LUDI-7B) that achieves a 3-token-per-step speedup over autoregressive decoding while matching masked diffusion baselines. The work suggests that UDLMs still have untapped potential for complex generation tasks.
