UnverifiedTraditional KV cache implementations pre-allocate contiguous GPU memory blocks of maximum length, resulting in an average of 60%–80% of pre-allocated memory being wasted.69% similarUnverified随着上下文长度增加，KV缓存的显存占用可达总显存的60%以上68% similarUnverifiedTaking the LLaMA-3 70B model as an example, with 80 layers, head_dim=128, and BF16 precision, each token occupies approximately 80KB of KV cache.67% similarUnverifiedThe KV Cache memory sharing mechanism can save up to 55% of GPU memory in scenarios such as beam search.67% similar
