SpecPilot: Autonomous Algorithm Discovery and Systems Optimization for Speculative Decoding

A paper titled "SpecPilot: Autonomous Algorithm Discovery and Systems Optimization for Speculative Decoding" questions whether released parallel-drafting systems achieve the full speedup that parallel drafting permits for memory-bound LLM decoding, where a lightweight drafter drafts a whole block in one forward pass. The work proposes autonomous algorithm discovery and systems optimization aimed at closing that gap.

Speculative decoding accelerates memory-bound LLM decoding with a lightweight drafter, and parallel drafters extend this speedup by drafting a whole block in one forward pass. However, it remains unclear whether their released systems stock attain the full speedup that parallel drafting permits. W
