Speculative Decoding Pipelines

Also known as: SpecDec Pipelines, Draft-Verification Decoding

An inference acceleration technique that uses a smaller draft model to propose tokens validated in parallel by a larger target LLM.

What Speculative Decoding Pipelines is

Speculative Decoding Pipelines achieve 2x to 3x speedups in token generation without altering the target model's output distribution.

How it works

A lightweight draft model generates candidate sequences which the target model evaluates simultaneously in a single forward pass.

Why it matters

Crucial for latency-sensitive applications like real-time code completion, customer voice agents, and interactive chat.
