Benchmark
| Workload Scenario | Cohere Command R+ | GLM-4.5 (Z.ai) | Price Delta |
|---|---|---|---|
| 1M input tokens (raw text) | $2.50 | $0.60 | +$1.90 |
| 1M output tokens (generation) | $10.00 | $2.20 | +$7.80 |
| 1M tokens · 70% input / 30% output mix | $4.75 | $1.08 | +$3.67 |
| Standard chat turn (4K in / 800 out, 50% cached) | $0.018 | $0.00318 | +$0.0148 |
| Monthly scale (10K requests / day) | $5,400.00 | $954.00 | +$4,446.00 |
Negative difference = Cohere Command R+ is cheaper. Positive = GLM-4.5 (Z.ai) is cheaper.
Scaling Curve
Total cost of a token volume at 70/30 input/output split (uncached). Log-log scale.
Verdict
GLM-4.5 (Z.ai) is cheaper on both input and output rates, so it costs less at every input/output mix. Price alone still isn't the whole decision: capability, latency and context limits (Cohere Command R+: 128K, GLM-4.5 (Z.ai): 128K) may justify the premium for your task.
FAQ
