VerifiedKV Cache is the persistent storage of intermediate states in the Transformer attention mechanism, recording the key and value vectors for each attention head's processed tokens across all layers, thereby skipping redundant forward propagation computations.70% similarUnverifiedSGLang achieves efficient KV Cache reuse through innovations such as RadixAttention, and can deliver several-fold throughput improvements when handling complex multi-turn dialogue and Agent Loop scenarios.68% similarUnverifiedPrompt caching relies on the Transformer's KV cache mechanism, skipping redundant computation by reusing already-computed KV vectors for identical prefixes, saving GPU compute and reducing time-to-first-token latency.65% similarUnverified将复杂指令拆解为多个专注的子模块有助于减少LLM在处理长指令时的注意力稀释问题64% similarUnverifiedIn the Transformer architecture, generating each new token requires attention computation over all previous tokens, and KV Cache avoids redundant computation by caching previously computed key-value pairs.63% similar
