JetSpec++ paper introduces faster LLM inference with speculative decoding

Researchers have developed JetSpec++, a novel approach to speculative decoding that significantly enhances the speed of large language models. By employing intra-block self-refinement and inter-block foresight drafting, JetSpec++ can achieve up to a 7.45x speedup over traditional autoregressive decoding. This method allows for the drafting of new token blocks before the current ones are fully verified, effectively overlapping drafting and verification stages to minimize wall-clock costs. Tested on GB200 hardware, JetSpec++ demonstrated a throughput of 1,361 tokens per second with an average acceptance length of nearly nine tokens across various benchmarks, while maintaining the output distribution of the target model.
