PairFlow: Closed-Form Source-Target Coupling for Few-Step Generation in Discrete Flow Models
ICLR 2026poster
We introduce $\texttt{PairFlow}$, a lightweight preprocessing step for training Discrete Flow Models (DFMs) to achieve few-step sampling without requiring a pretrained teacher. DFMs have recently emerged as a new class of generative models for discrete data, offering strong performance. However, the…
