Llama.cpp Multi-Token Prediction Support Enters Beta, Closing the vLLM Performance Gap

What Is MTP

Multi-Token Prediction (MTP) enables a model to predict multiple tokens per inference step rather than one at a time, significantly boosting generation throughput. Server-side inference frameworks like vLLM already support MTP, giving them a speed edge over llama.cpp in high-throughput scenarios — until now.

Beta Status

A post scoring 277 on r/LocalLLaMA announced that llama.cpp's MTP implementation has entered beta, thanks to contributor Aman and the broader community. Current support is limited to Qwen3.5 MTP, with other model families expected to follow.

The developer noted: "Between this and the maturing tensor-parallel support, expect most performance gaps between llama.cpp and vLLM, at least when it comes to token generation speeds, to be erased."

Impact for Local Inference

llama.cpp is the de facto standard for running LLMs on consumer hardware. Once MTP stabilizes, local inference speeds for models like Qwen3 and Llama 4 should approach server-grade performance, removing one of the last meaningful advantages of cloud-hosted inference for many workloads. The pull request is in review and expected to merge to main shortly.

r/LocalLLaMA argues Qwen3.5 27B is where local speed, quality, and hardware practicality meet

A recent r/LocalLLaMA post presents Qwen3.5 27B as an unusually strong local inference sweet spot. The author reports about 19.7 tokens per second on an RTX A6000 48GB with llama.cpp and a 32K context, while the comments turn into a detailed debate about dense-versus-MoE VRAM economics.

LocalLLaMA lights up over Hipfire as AMD finally gets its own inference speed story

LocalLLaMA upvoted Hipfire because it felt like overdue attention for RDNA users, not just another repo drop. The thread filled with early tests showing multi-fold decode gains and immediate questions about quant formats and compatibility.

A GBNF tweak that slashed Qwen3.6 token churn gave LocalLLaMA a rare practical win

LocalLLaMA got animated because the post promised something people can feel immediately: less reasoning drag. A user claims a small GBNF constraint cut Qwen3.6 token burn hard enough to speed up long tasks without wrecking benchmark scores.
