S31 | Discrete Beckmann Transport Models for One-Step Language Modeling and Reasoning
Sophia Tang presents Discrete Beckmann Transport Models, which reach one- and few-step generation in discrete flow models without distilling a pretrained teacher. DBTM builds on a time-independent flow whose autonomous transport map provably carries any point to a fixed point on the vertices of the simplex in a single step, a property characterized by a conservation equation whose residual is minimized directly from data. Generation then reduces to iterating one map until it reaches a fixed point, improving quality and accuracy over discrete diffusion and continuous flow baselines.
S30 | DFlash: Block Diffusion for Flash Speculative Decoding
Jian Chen presents DFlash, a speculative decoding framework that replaces autoregressive drafting with a lightweight block diffusion model, so all draft tokens come out of a single forward pass. Conditioning the draft model on context features extracted from the target model keeps draft quality and acceptance rates high. DFlash reaches over 6x lossless acceleration across a range of models and tasks, up to 2.5x higher speedup than EAGLE-3.
S29 | Unlocking Lossless Speedups in LLMs via Discrete Diffusion
Uno is a diffusion-augmented LLM that defines an autoregressive model distribution and uses diffusion to draw several tokens in parallel from that same distribution, so it accelerates generation without sacrificing the quality of the underlying AR model and needs no separate draft model. Uno beats leading speculative-decoding methods in throughput at every batch size and reaches up to 3x speedups over the base AR model, and the 8B Uno outperforms the 26B DiffusionGemma and the proprietary Mercury 2 on agentic tool use, coding, and long-context reasoning.

About the Reading Group
Diffusion LLMs are faster, more controllable successors to traditional LLMs and are rapidly gaining adoption. This reading group builds a community for exchanging and debating emerging ideas in this space. While our primary focus is discrete diffusion models for language, we also welcome work on other modalities and applications, such as molecular design, drug discovery, and beyond.
