How speculative decoding speeds up inference using a small draft model.
11 min · Reviewed 2026
The premise
Speculative decoding can 2-3x inference throughput when configured well.
What AI does well here
Use a small fast model to draft tokens for a large verifier.
Maintain identical output distribution to the target model.
Trade GPU memory for latency.
What AI cannot do
Help when the draft model has poor agreement with the target.
Improve quality — only speed.
Practice this safely
Use a small project example from your own work. The useful move is to compare the AI's draft against your goal, sources, and constraints before you trust it.
Ask AI to explain speculative decoding in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "Speculative Decoding for Faster LLM Inference" and ask for two possible next steps plus one reason each step might be wrong.
Check draft model against a trusted source, teacher, adult, expert, or original document before you use it.

How should AI output about speculative decoding be treated?
As proof that no other source is needed
As a replacement for context, consent, or expert review
As a draft or helper output that still needs human judgment and verification
As something that becomes correct when it sounds confident
