New technique speeds up LLM inference by pre-decoding sessions

Researchers have introduced a new technique called speculative pre-positioning to improve the efficiency of stateless inference servers for large language models. This method decodes sessions forward to their next decision point, effectively moving prefill and entry-decode tasks off the critical path. The approach aims to reduce latency by allowing the next request to resume from a pre-paid entry or, under certain confidence thresholds, be answered from a cached distribution with a quick vocabulary scan, significantly cutting down response times compared to traditional methods.
