DeepSeek's DSpark framework rearms speculative decoding for high-concurrency serving
Semi-autoregressive decoding just broke the 85% speed barrier in production AI inference
A new speculative decoding framework from DeepSeek tackles the two bottlenecks that have limited parallel drafters: suffix decay and wasteful verification. DSpark achieves 60, 85% faster generation speeds in production by coupling a semi-autoregressive architecture with a confidence-scheduled scheduler that prunes low-value tokens before the target model verifies them.
