Paper Proposes Reusing Rejected Tokens to Speed Up Speculative Decoding
A new arXiv paper introduces a technique called carryover drafting that reuses the model states computed for rejected draft tokens during speculative decoding. Because verification already produces representations for both accepted and rejected tokens, the method puts the discarded ones to further use instead of throwing them away. The goal is to improve the efficiency of LLM inference, where speculative decoding lets one target forward pass accept multiple drafted tokens at once.
