English(EN) What a 70% vs 90% prompt cache hit rate does to an AI agent’s bill (72 models priced)

AI代理成本受提示缓存命中率的显著影响

一项最新分析探讨了提示缓存对AI代理的显著成本影响,展示了缓存命中率如何直接影响计费。研究发现,缓存命中率从70%提高到90%(提高20%),可以将中位数任务成本降低38%。对于某些模型而言,更高的缓存命中率比切换到更便宜的模型更具成本效益。分析还指出,对于某些模型,在特定命中率阈值以下缓存会产生费用,并提供了优化缓存性能的策略,例如一致地排序提示和衡量缓存利用率。 AI

影响 优化提示缓存可以显著降低AI代理的运营成本,更有效地利用昂贵的模型资源。

    70%与90%的提示缓存命中率对AI代理账单有何影响(72种模型定价)

    <p>An agent sends the same long prefix on every step: system prompt, tool definitions, the files it has read, the conversation so far. Most of it is already in the provider's prompt cache from the step before. How much of it is, the cache hit rate, ends up deciding most of the bi…
