·2026.05.18 00:42

Key point

An update has been released for llama.cpp that optimizes prompt decoding performance when using MTP.

Details

A new Pull Request (#23198) in the llama.cpp project has improved prompt processing speed for MTP (Multi-Token Prediction) models.

The key change prevents unnecessary logit copying that occurs during the prompt decoding process.

This increases the efficiency of the prompt processing stage, and an overall improvement in inference performance can be expected.
