1. Full-Turn Rate-Card Substitution for DeepSeek-V4 Pro (0813): At an uncached input rate of $0.66/1M, output rate of $1.98/1M, and warm cache read rate of $0.066/1M, running 10 consecutive 150,000-token coding agent turns (with 2,000 output tokens/turn) without prefix pinning costs $1.0296. Locking 100% static prefixes (Case A: 1 cold turn + 9 warm cached turns + 20K total output) reduces 10-turn spend to $0.2277 (saving $0.8019); under a 90% static prefix + 10% dynamic tail workload (Case B), 10-turn spend is $0.3079.
2. Full-Turn Rate-Card Substitution for Google Gemini 4 Hydrogen & Winner Verdict: On Google Gemini 4 Hydrogen ($0.15/1M input, $0.6/1M output, $0.015/1M warm cache), 10 unpinned 150K turns cost $0.2370, dropping to $0.0547 in Case A and $0.0730 in Case B. Across every 10-turn 150K coding loop (including output tokens), Google Gemini 4 Hydrogen delivers an additional $0.1730 Case-A cost advantage.
Production Workload TCO: 25,000 MAU • 50M Tokens/Mo (50% Cache Hit) • 2,000 GB Egress
💡 Optimal FinOps Verdict: Deploying Google Gemini 4 Hydrogen saves $25.02/month ($300/year) at 25,000 MAU & 50M monthly tokens (80% input / 20% output split with 50% prefix cache hit rate).
