The Prompt Caching Miss Trap: Why Your Context Cache Fails & How to Cut Costs by 80%
Prompt Caching promises 50% to 90% savings on long context costs, but many engineering teams find hit rates hovering below 20%, resulting in surprising end-of-month bills. This article dissects the 5 root causes of cache misses across OpenAI, Claude, and Gemini (prefix breakage, dynamic timestamp pollution, unaligned block sliding, ephemeral TTL limits, and cluster cold starts), offering an industrial-grade cache stabilization architecture and APIBox discount strategy to slash production bills by 80%.
