DScout paper boosts LLM inference speed with optimized speculative decoding

A new paper introduces DScout, a method to improve the speed of speculative decoding in large language models. DScout optimizes both the training and inference phases of diffusion drafters, which are used to propose tokens in parallel. By factorizing loss during training and throughput during inference, DScout aims to better align token acceptance with latency trade-offs. Experiments show DScout achieves significant speedups, with 3.84x and 4.14x mean speedups over autoregressive decoding on Qwen3-4B and Qwen3-8B models, respectively, outperforming existing state-of-the-art baselines.
