Multi-token prediction

Also known as multi-token prediction heads

In plain English

MTP lets the model guess several upcoming tokens at once and then verify them, reducing the number of slow one-token-at-a-time steps.

Technical definition

Multi-token prediction uses auxiliary heads trained with the model to propose multiple future tokens for speculative verification.

Engineering details

Unlike a separate draft model, MTP proposals come from the target model’s own representation. This can improve proposal alignment and simplify deployment, but it requires a checkpoint trained with compatible MTP modules and engine support for the verification path.

Why it matters

MTP can exchange otherwise underused compute for fewer memory-bound decode steps. Gains are largest when draft acceptance is high and verification fits into available compute; at large batches the extra work may provide less benefit.

How to read it in InferenceX

InferenceX reports MTP as a recipe dimension. Acceptance rate or acceptance length, workload distribution, numerical quality checks, and matched interactivity all matter when translating a benchmark gain to production.
