UnverifiedIn large model API call scenarios, cache hit rate refers to the reuse ratio of the KV Cache (key-value cache), where the model can directly read the attention key-value pairs of already-processed tokens from the cache.68% similarUnverifiedCodex内置Prompt Caching缓存机制，实测缓存命中率可达84%至93%66% 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66% similarUnverifiedThe KV Cache memory sharing mechanism can save up to 55% of GPU memory in scenarios such as beam search.64% similarUnverifiedTraditional 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.64% similar
