Beyond DeepSeek: Open‑Source JetSpec and Other Projects Accelerate Large‑Model Decoding Up to 10×

The article compares DSpark and JetSpec, two recent open‑source speculative decoding frameworks that tackle inference efficiency from system‑level verification reduction and algorithmic token‑acceptance improvements, respectively, showing up to 9.64× end‑to‑end speedup on Qwen3‑8B and significant gains across math, code, and dialogue benchmarks.
