Researchers have developed STAIR (Stale-Token Attention for Inter-query Reuse), a novel method to improve how large language models utilize information from previous problems within the same conversation. Preliminary experiments showed that retained history can either help or hinder performance, even within the same domain. STAIR works by capturing keys and values from earlier response generations in a fixed bank and learning to redirect current queries to this bank during prompt processing. This approach, which only trains 12,288 parameters while keeping the base model frozen, has demonstrated an improvement of up to 11.67 percentage points in average later-turn accuracy across three Qwen models and four benchmarks.
