OptiQ overcomes MTP integration hurdles for Apple Silicon speedup

By PulseAugur Editorial · [1 sources] ·

The development team at OptiQ encountered significant challenges integrating Multi-Token Prediction (MTP) into their OptiqEngine for Apple Silicon, despite initial expectations of a quick implementation. They identified and resolved three key issues: excessive memory duplication caused by loading the model twice, an incorrect verification method for speculative decoding at higher temperatures, and the need to apply sampling truncation consistently on both the draft and verification paths. These fixes ultimately enabled them to achieve a 1.4x speedup for Qwen3.5 models, matching previously published benchmarks. AI

IMPACT Enables faster inference for LLMs on Apple Silicon by optimizing speculative decoding techniques.

RANK_REASON The item details technical implementation challenges and solutions for integrating a specific feature (MTP) into a particular software engine (OptiqEngine) for a specific hardware platform (Apple Silicon), which falls under tooling and infrastructure.

    Getting MTP to actually work on Apple Silicon

    <p>Qwen3.5 and Qwen3.6 ship with a small extra prediction head bundled into the model. The literature calls it MTP, short for Multi-Token Prediction. The point of having it is to use the head as a draft model for speculative decoding: it spits out K candidate tokens fast, and the…
