What is
Speculative Decoding?
An inference technique using a smaller "draft" model to propose tokens that a larger model verifies.
By Anish· Founder · Vedwix
·Definition
Speculative decoding pairs a fast small model with a slow large model. The small model proposes several tokens; the large model verifies them in parallel. Verified tokens are accepted; rejected tokens fall back to the large model. The result: significantly lower latency without quality loss.
Example
A 70B model runs alongside a 7B "draft" model — the system serves at near-7B speed with 70B quality.
How Vedwix uses Speculative Decoding in client work
Used in self-hosted serving for latency-sensitive workloads.
