Bell-shaped time sampling — drawing the corruption level near t=0.5 — accelerates masked diffusion language model training by up to ~4× without changing the final loss.
ChunkFlow achieves up to 1.28x step-time speedup and up to 49% lower peak GPU memory for DiT inference by using a first-order model to guide communication-aware chunked prefetching.
