UnverifiedIn HITL implementations, process instances are persisted in storage and resume execution after receiving a human approval signal, consuming no computing resources during the waiting period.63% similarUnverifiedPrompt Caching is transparent to the caller: the request still needs to be sent, the network round-trip still exists, the model still runs the remaining inference, and latency remains in the range of seconds.63% similarUnverifiedImplementing retry logic with exponential backoff at the API call layer and caching results of high-frequency requests can provide a buffer during brief service fluctuations.62% similarUnverifiedFor Agent applications with long system prompts or repeated use of the same documents, having the high-frequency repeated portions appear stably at the beginning of requests can improve cache hit rates and leverage lower pricing tiers.62% similarVerifiedThe general principle for achieving cache hits is to keep the prefix of the request context as stable as possible, placing fixed content such as system prompts and tool definitions at the very front, with per-turn user input appended at the end.61% similar
