DeepSeek-R1 (Reasoner) vs Zhipu GLM 5v Turbo — API Pricing, 150K Cache & Latency Benchmark
Side-by-side unit economics audit comparing DeepSeek-R1 (Reasoner) (deepseek/deepseek-reasoner: Input $0.55/1M, Output $2.19/1M, Warm Cache Read $0.14/1M) against Zhipu GLM 5v Turbo (zhipu/zhipu-glm-5v-turbo: Input $1/1M, Output $4/1M, Warm Cache Read $0.1/1M).
Activate 4-breakpoint prefix caching on DeepSeek-R1 (Reasoner) to cut input token costs from $0.55/1M down to $0.14/1M, or route async workloads via Batch API for 50% off.
Lock static system prompt prefixes on Zhipu GLM 5v Turbo to pay $0.1/1M warm cache rates instead of $1/1M uncached input, plus eligible startup cloud credits.
In Etuki FinOps telemetry comparing DeepSeek-R1 (Reasoner) (API ID: deepseek/deepseek-reasoner) vs Zhipu GLM 5v Turbo (API ID: zhipu/zhipu-glm-5v-turbo), DeepSeek-R1 (Reasoner) offers lower standard uncached input pricing at $0.55/1M tokens, while DeepSeek-R1 (Reasoner) leads in 10-turn 150K cache-pinned coding economics at $0.3153 per 10 turns (saving $0.0497 over Zhipu GLM 5v Turbo). For latency-sensitive interactive agents, Zhipu GLM 5v Turbo delivers 393ms faster P90 time-to-first-token (487ms vs 880ms).

1. Full-Turn Rate-Card Substitution for DeepSeek-R1 (Reasoner): At an uncached input rate of $0.55/1M, output rate of $2.19/1M, and warm cache read rate of $0.14/1M, running 10 consecutive 150,000-token coding agent turns (with 2,000 output tokens/turn) without prefix pinning costs $0.8688. Locking 100% static prefixes (Case A: 1 cold turn + 9 warm cached turns + 20K total output) reduces 10-turn spend to $0.3153 (saving $0.5535); under a 90% static prefix + 10% dynamic tail workload (Case B), 10-turn spend is $0.3707.
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), DeepSeek-R1 (Reasoner) delivers an additional $0.0497 Case-A cost advantage.
Production Workload TCO: 25,000 MAU • 50M Tokens/Mo (50% Cache Hit) • 2,000 GB Egress
💡 Optimal FinOps Verdict: Deploying DeepSeek-R1 (Reasoner) saves $26.30/month ($316/year) at 25,000 MAU & 50M monthly tokens (80% input / 20% output split with 50% prefix cache hit rate).
