## What a real workload costs

Take 1,000,000 requests a month at 1,200 input and 350 output tokens each: 1,200M input and 350M output tokens. At list prices that is 1,200 × $1.40 + 350 × $4.40 = $3,220 a month. Billed on Allocate it is $3,445.

## Common questions

### How much does GLM 5.3 cost per million tokens?

Provider list price is $1.40 per million input tokens and $4.40 per million output tokens. On Allocate you pay $1.50 in and $4.71 out.

### What context window does GLM 5.3 have?

1,048,575 tokens (1M). At roughly 0.75 words per token, that is about 786k words of English text per request.

### What does cached input cost on GLM 5.3?

$0.26 per million tokens at list ($0.28 billed). Repeated prompt prefixes, such as a stable system prompt or tool definitions, bill at this rate instead of the full input price.

### Can I fine-tune GLM 5.3?

Yes. GLM 5.3 is an open-weights model; check the lab’s model card for the exact license terms. Read the license terms before fine-tuning for commercial use. On Allocate the trained weights stay inside your boundary and belong to you.

### Has the price of GLM 5.3 changed?

Allocate has checked the provider list price hourly since 12 Sep 2026. It has not changed in that time. The price history chart on this page shows every change.

### How do I call GLM 5.3 on Allocate?

Send z-ai/glm-5.3 in the model field of the OpenAI-compatible endpoint at api.allocate.network/v1, or point a route name (like prod/support-agent) at it so you can swap the model later without a deploy.
