S27 | From Interface to Inference: Eliciting Any-Order Inference from Any-Order Models

Seunggeun Kim and Jaeyeon Kim show that the any-order prediction interface of masked diffusion models does not by itself deliver any-order inference, because fixed-canvas token-level models may know what semantic component should appear without knowing where to place it. They propose two fixes: insertion-based masked diffusion, which relaxes fixed-position commitments and generates across non-contiguous regions, and latent-space masked diffusion, which predicts coarser semantic segments and enables search over latent generation orders. A 7B FlexMDM for Python coding and a 125M LatentMDM for GSM8K both show distinct any-order inference behaviors and improved downstream performance.

S26 | Self-conditioned Flow Map Language Models via Fixed-point Flows

Jaehoon Yoo and Wonjung Kim study self-conditioning in flow-based language models, where the model denoises text while conditioning on its own denoising estimate. They show that self-conditioning solves a fixed-point iteration that bootstraps the learned denoiser, and they use this view to define fixed-point flows, a two-dimensional class of self-conditioned flows spanning the flow process and the fixed-point iteration. Distilling both dimensions yields FMLM★, a flow map language model that outperforms state-of-the-art self-conditioned and few-step models in one- and few-step generation on OpenWebText.

S25 | FLARE: Diffusion for Hybrid Language Model

Yuchen Zhu (Georgia Tech) presents FLARE, a framework that turns a hybrid-attention autoregressive (AR) LLM into one that also runs diffusion-style parallel decoding, so a single checkpoint supports both AR verified decoding and diffusion denoising. The authors find that transfer data quality, more than the loss formulation or attention-mask design, decides how much of the seed checkpoint's capability survives. Starting from strong AR checkpoints with limited post-training data, FLARE matches leading open-source diffusion LLMs across scales and delivers consistent throughput gains in single-GPU concurrent serving.

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.
