Prompt caching is a critical technique for improving the efficiency of large language models, particularly for coding agents that process lengthy and repetitive inputs. This method stores the computed attention states (KV cache) from previous tokens, allowing subsequent requests with similar prefixes to avoid recomputing them. The effectiveness and fragility of prompt caching are influenced by factors like tool definitions, model changes, and routing decisions, impacting latency, cost, and feature availability. The KV cache itself consists of key and value tensors generated for each token during the prefill phase, which are then reused during decoding to attend to prior context without re-computation. AI
