Specifically, during inference, upon encountering an anchor token that condenses the comprehensive semantic information of preceding tokens in the current sequence, the model can reduce the keys/values caches by deleting the caches of non-anchor tokens within that sequence. We introduce the inference method in Algorithm 1. The function “REDUCTION” in Line 1 is utilized to remove keys/values caches when the model processes prefix texts in Line 10 or generates an anchor token during the prediction of the next token in Line 16. This approach aims to reduce the keys/values caches for both prefix tokens and generated outputs during real-time inference. This paper is available on arxiv under CC BY 4.0 DEED license.
