Awesome Diffusion Language Models

Awesome https://arxiv.org/abs/2508.10875

One of the most starred, comprehensive and up-to-date collections of Diffusion Language Model papers, code and resources! If you find this repository helpful, please consider giving it a ⭐ to support.

Timeline of Diffusion Language Models

This figure highlights key milestones in the development of DLMs, categorized into three groups: continuous DLMs, discrete DLMs, and recent multimodal DLMs. We observe that while early research predominantly focused on continuous DLMs, discrete DLMs have gained increasing popularity in more recent years.
