Why Is Speculative Decoding Fast? A visual explainer of LLM inference acceleration
gmays · hn · 2026-10-19
This blog post explains why speculative decoding speeds up LLM inference: a small draft model proposes candidate tokens that the large model verifies in parallel, yielding multiple tokens per forward pass without changing output quality. It walks through the mechanics and how draft-target agreement and acceptance rates determine the real-world speedup.
