How much does GLM-5.2 cost per 1,000 requests?
Computed from generated token pricing. Each row assumes the listed input and output tokens per request; output is adjusted by this model's measured 3.87× verbosity factor.
| Request shape | Input tokens | Output tokens | Cost / 1,000 requests |
|---|---|---|---|
| Short | 100 | 50 | $0.9914 |
| Medium | 1,000 | 500 | $9.9140 |
| Long | 4,000 | 2,000 | $39.6560 |
Formula: ((input price × input tokens) + (output price × output tokens × verbosity factor)) ÷ 1,000,000 × 1,000. Assumptions: short 100/50, medium 1,000/500, long 4,000/2,000 input/output tokens per request. Verbosity run: 2026-06-21T00:00:00.000Z.
Three model-specific pricing decisions
GLM-5.2’s direct-API bill is calculated here. Open-weight, hardware, region, currency, cache, and batch questions remain explicit evidence gaps.
1. GLM-5.1 → 5.2 coding-agent migration bill
| Fixed workload (input / output) | GLM-5.2 | GLM-5.1 | Decision boundary |
|---|---|---|---|
| Coding · 8,000 / 1,200 | $1648.00 | $744.00 | 15% accepted-result uplift required to justify the higher bill |
| Long coding · 32,000 / 4,000 | $6240.00 | $2800.00 | 20% accepted-result uplift required to justify the higher bill |
Formula: 100,000 × (input tokens × input $/M + output tokens × output $/M) ÷ 1,000,000. Uplift is a decision threshold, not a measured quality claim.
2. 1M-context long-horizon coding ladder
| Context shape | Input / output | GLM-5.2 / 100K | Expansion boundary |
|---|---|---|---|
| 128K | 128,000 / 2,000 | $18800.00 | Output is fixed at 2K |
| 512K | 512,000 / 2,000 | $72560.00 | Linear token sensitivity only |
| 1M | 1,000,000 / 4,000 | $141760.00 | Context fit/output behavior needs model evidence |
3. Direct API versus open-weight deployment ledger
| Deployment | Dated calculation | Unavailable inputs | Decision |
|---|---|---|---|
| Direct Z.ai API | $1648.00 | $1.40 / $4.40 per M | Sourced token spend |
| Open-weight | No API bill | Hardware, utilization, region, currency, cache, batch | User-supplied model required |
