The KV cache stores the attention key-value pairs of all previous tokens during an Agent's multi-turn interactions to avoid recomputation, but its VRAM usage grows linearly or even near-linearly with context length, so long-context Agents easily hit the VRAM limit.

UnverifiedKV Cache reuse targets the repeated prefix context in multi-turn agent conversations, avoiding recomputing attention on each inference, thereby reducing latency.77% similarVerifiedKV 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.73% similarUnverifiedTransformer 架构中自注意力层会为每个 Token 生成对应的 Key 和 Value 向量并缓存在 GPU 显存中，即 KV Cache 机制，上下文越长占用显存越大，推理成本呈近线性增长72% similarUnverifiedThe persistent context mechanism explicitly maintains a continuously updatable state cache, which is similar to the KV Cache mechanism of large language models in that both trade space for time.71% similarUnverifiedThe self-attention mechanism allows the model to dynamically weigh the importance of all other tokens in the sequence when processing each token, thereby capturing long-range semantic dependencies.69% similar
