DeepSeek DSpark: Speculative Decoding Boosts DeepSeek-V4 Generation Speed by 60-85%

Short summary

DeepSeek's DSpark module applies speculative decoding to DeepSeek-V4, achieving 60-85% faster per-user generation with no quality degradation. It simultaneously addresses weak draft quality and computational waste, two long-standing bottlenecks in speculative decoding. The technique is a production-ready inference optimization rather than a model architecture change.

• •DSpark adds speculative decoding to DeepSeek-V4
• •Per-user generation speed up 60-85% with no quality drop
• •Solves both weak draft quality and resource waste simultaneously
