DeepSeek Ships DSpark, Claiming Up to 400% Throughput Gains

The lab open-sourced a speculative decoding method and a companion framework, DeepSpec, in a release that matters most for anyone running models on limited hardware.

DeepSeek released DSpark, a speculative decoding technique it claims improves throughput by between 51% and 400%, alongside open-sourcing a framework called DeepSpec, as flagged by @Yuchenj_UW. Speculative decoding works by using a smaller, faster model to draft tokens that a larger model then verifies in parallel, cutting the latency of generation without sacrificing output quality. The wide range in the claimed speedup reflects how much it depends on workload, but even the low end is a meaningful win.
