Long contexts significantly increase the GPU memory footprint of the KV Cache, which is often mitigated in engineering through grouped-query attention (GQA), KV Cache quantization or paged management.

UnverifiedVRAM consumption for context length grows approximately quadratically as length increases, because the attention mechanism must maintain a KV Cache storing the intermediate states of historical tokens78% similarUnverifiedOnline inference pursues first-token latency and tail latency, requiring continuous batching, preemptive scheduling and fine-grained KV Cache paging management.75% similarVerifiedKV Cache reduces latency and computing resource consumption in long-sequence generation by caching the attention key-value pairs of historical tokens, avoiding repeated computation over the entire historical sequence at each generation step.75% similarUnverifiedSome inference frameworks provide KV cache quantization or paged management to alleviate KV cache overhead.68% similarUnverifiedThe context window is measured in Tokens and determines how much code or documentation the model can process at once; long file analysis often requires segmented processing.64% similar
