ResiSpec框架提升LLM推测解码效率

研究人员推出ResiSpec,一个旨在提高大型语言模型(LLM)推测解码效率的新框架。推测解码通常使用一个草稿模型来预测未来token,然后由一个更大的模型进行验证。然而,多候选方法可能会遇到“残差漂移”问题,即早期候选的拒绝会导致后续候选的分布发生偏离,从而导致低效的重采样。ResiSpec通过在验证过程中重塑提议分布来解决这个问题,将残差目标质量保持在草稿模型的高置信度区域内。据报道,该方法在不牺牲输出准确性的情况下,与现有的多候选技术相比,速度提升高达1.92倍。 AI

影响 这项研究通过降低推理过程中的计算开销,有望实现更高效的大型语言模型的部署和服务。

    The efficiency of Large Language Model (LLM) serving is fundamentally limited by the sequential nature of autoregressive decoding. Speculative Decoding (SD) mitigates this by using a lightweight draft model to speculate future tokens, which are then validated by the LLM in a sing…
