SemiAnalysis has introduced JetSpec, a new method for speculative decoding that significantly reduces latency in large language models. By co-optimizing drafting cost and quality with a causal parallel tree drafting approach, JetSpec achieves up to a 9.64x speedup on the MATH-500 benchmark and a 4.58x speedup in open-ended chat scenarios. The researchers anticipate deeper integration with inference engines like vLLM and SGLang. AI
