EvoSpec: Evolving Speculative Decoding via Real-Time Vocabulary and Parameter AdaptationTarget
arXiv:2605.27390v1 Announce Type: cross Abstract: Speculative decoding accelerates Large Language Model inference via a draft-then-verify paradigm, yet the output projection layer becomes a bottleneck as vocabulary sizes scale. While existing static pruning methods effectively reduce this overhead, they suffer from precipitous drops in acceptance rate in specialized domains or topic-switching scenarios due to their inability to capture dynamic distribution shifts. To address this, we introduce EvoSpec, a framework that enables real-time evolution of the draft model through dynamic vocabulary a
The increasing computational demands and scaling vocabulary sizes of large language models are creating bottlenecks in inference, making real-time adaptation solutions critical.
Improving the efficiency and adaptability of LLM inference directly impacts deployment costs, accessibility, and the practical application range of advanced AI models.
Optimized speculative decoding can significantly reduce the computational overhead for large language models, especially in dynamic or specialized AI applications.
