# Factorization-Guided Training and Inference for Diffusion-Drafted Speculative Decoding > Source: > Published: 2026-10-20 04:30:01+00:00 Speculative decoding accelerates large language model inference through parallel verification of tokens proposed by a drafter. Diffusion drafters further parallelize proposal generation, but greater proposal capacity or higher mean accepted tokens (MAT) need not yield higher throughput. Because veri
