What is Speculative decoding?

Source: local-llm.net/glossary

An inference optimization where a smaller, faster "draft" model generates candidate tokens that are then verified by the larger "target" model in parallel. Tokens that the target model agrees with are accepted immediately, speeding up generation without any quality loss. Effective when the draft model is a good approximator of the target.
