1. Full-Turn Rate-Card Substitution for Alibaba Qwen3.8-Max: At an uncached input rate of $0.8/1M, output rate of $2.4/1M, and warm cache read rate of $0.08/1M, running 10 consecutive 150,000-token coding agent turns (with 2,000 output tokens/turn) without prefix pinning costs $1.2480. Locking 100% static prefixes (Case A: 1 cold turn + 9 warm cached turns + 20K total output) reduces 10-turn spend to $0.2760 (saving $0.9720); under a 90% static prefix + 10% dynamic tail workload (Case B), 10-turn spend is $0.3732.
2. Full-Turn Rate-Card Substitution for Zhipu GLM 5v Turbo & Winner Verdict: On Zhipu GLM 5v Turbo ($1/1M input, $4/1M output, $0.1/1M warm cache), 10 unpinned 150K turns cost $1.5800, dropping to $0.3650 in Case A and $0.4865 in Case B. Across every 10-turn 150K coding loop (including output tokens), Alibaba Qwen3.8-Max delivers an additional $0.0890 Case-A cost advantage.
Production Workload TCO: 25,000 MAU • 50M Tokens/Mo (50% Cache Hit) • 2,000 GB Egress
💡 Optimal FinOps Verdict: Deploying Alibaba Qwen3.8-Max saves $20.40/month ($245/year) at 25,000 MAU & 50M monthly tokens (80% input / 20% output split with 50% prefix cache hit rate).
