Prompt Caching Methodology & Mathematical Formulation

This mathematical engine calculates effective token throughput by decomposing input requests into static system/RAG prefixes and dynamic query payloads. Cache writes are modeled per TTL lifecycle (e.g. 5-minute rolling window or explicitly pinned caches), while cache read hits are factored at official provider discount tiers (up to 90% cost reduction on Anthropic and DeepSeek pipelines).
