Atomic Chat has demonstrated significant improvements in local language model performance by implementing Multi-Token Prediction (MTP), which increased the token generation speed of Qwen models on dense 27B from 51 to 117 tokens per second and on the MoE 35B-A3B model from 218 to 267 tokens per second. This advancement is particularly noteworthy as it effectively reduces the memory bandwidth bottleneck commonly faced by local models, allowing for faster generation without sacrificing accuracy. The integration of MTP has led to an impressive ~80% acceptance rate for drafted tokens, requiring only minimal additional VRAM, further enhancing its utility for developers and power users who seek privacy and offline capabilities in their AI applications.

Qwen: Qwen is a family of large language models developed by Alibaba Cloud, available in dense and mixture‑of‑experts variants and widely adopted in both cloud and local inference setups due to strong performance and permissive licensing. Here, Atomic Chat is showcasing Qwen 3.6 27B and the 35B‑A3B MoE model as benchmarks to demonstrate how MTP can dramatically improve token generation speeds for local LLM users running these models on high‑end GPUs.
Atomic Chat: Atomic Chat is an open‑source ChatGPT alternative that lets users run large language and vision-language models locally or connect to cloud models through an OpenAI‑compatible API, with a custom inference stack optimized for CPUs, GPUs, and Apple Silicon. In this news item, Atomic Chat is highlighting how its implementation of Multi‑Token Prediction delivers major speedups for local Qwen models while preserving answer quality, underscoring its focus on fast, privacy‑preserving on‑device AI.
MTP (Multi-Token Prediction): MTP (Multi‑Token Prediction) is an inference technique where a model drafts multiple future tokens in parallel and then verifies them in a single pass, reducing redundant computation and memory traffic compared with standard one‑token‑at‑a‑time decoding. In this context, Atomic Chat reports that its MTP implementation significantly accelerates dense and MoE Qwen models on consumer GPUs with high draft‑token acceptance and no observed loss in output accuracy.
