English(EN) XPress: Parallel Refinement for Diffusion Drafters in Speculative Decoding

XPress增强了扩散模型的投机解码

研究人员开发了xPress,一种改进扩散草稿器(diffusion drafters)中投机解码(speculative decoding)的新方法。该技术解决了扩散模型中独立采样的token的问题,这可能导致联合概率不高的序列。通过并行恢复草稿token块的因果依赖关系,xPress显著提高了接受长度(acceptance length)和端到端解码吞吐量(end-to-end decoding throughput)。在Qwen3-8B模型上跨各种基准的测试表明,与原始dFlash方法相比,接受长度平均增加了30%,吞吐量增加了1.3倍。 AI

影响 通过增强投机解码技术,提高了大型语言模型的推理速度和效率。

    XPress:用于投机性解码的扩散起草者的并行精炼

    arXiv:2608.02438v2 Announce Type: replace Abstract: Block-diffusion drafters like dFlash generate an entire block of draft tokens in a single forward pass, drastically reducing the overhead of multiple-token drafting in speculative decoding. The crucial final step of the single-p…
