Expert-Choice Routing Enables Adaptive Computation in Diffusion Language Models

Shuibai Zhang, Caspian Zhuang, Chihan Cui +8

Diffusion language models (DLMs) enable parallel, non-autoregressive text generation, yet existing DLM mixture-of-experts (MoE) models inherit token-choice (TC) routing from autore…
