DSpark

Overview

DSpark is an open-source speculative decoding framework that attaches a lightweight draft module to existing DeepSeek-V4 weights to speed up text generation.[8] It is designed as an inference engine component that can be integrated into serving stacks to reduce latency and cost for large language model workloads. Devs should care because it provides a practical performance boost for DeepSeek deployments without requiring model retraining, making it attractive for self-hosted LLM services and research clusters.[8]
