3. Prompt Caching Savings Math (At 10,000 DAU Workload)
Long system prompts, RAG document context, and multi-turn agent histories qualify for automatic or explicit prompt caching. Here is how cache hit rates change your monthly cloud bill:
| Prompt Cache Hit Rate | Amazon Nova Pro v1 (Read @ $0.20/1M) | GPT-4o Mini (Read @ $0.075/1M) | Combined Hybrid Router + 75% Cache |
|---|---|---|---|
| 0% Cache Hit (Cold Prompts) | $19,296/mo | $3,618/mo | $6,754/mo |
| 50% Cache Hit (Standard Chat) | $15,516/mo | $3,146/mo | $5,620/mo |
| 75% Cache Hit (Production Agent/RAG) | $13,626/mo | $2,909/mo | $5,053/mo |
| 90% Cache Hit (Heavy Document Context) | $12,492/mo | $2,768/mo | $4,712/mo |
