On ATP
The same governance applies to every model on the gateway:
- Project API key — spend and revocation bound to one project
- Model allowlist — only enabled models may be called
- Credits — 1 USD = 100 credits, debited per completed request
- Per-request logs — model, key, project, credits for audit
Cost estimator
A list-price estimate for a month of traffic. Actual spend follows each completed request.

FAQ
- How much does GLM-5.1 cost on ATP Token?
- List rates for GLM-5.1 (API id glm-5-1): input $1.54 / output $4.84 per 1M tokens. Billing uses credits (1 USD = 100 credits), debited from the project balance per completed request. There is no monthly platform fee; see Pricing for the minimum top-up.
- How do I call GLM-5.1 via API?
- Create a project API key, enable the API id glm-5-1 (not the display name) on that project’s allowlist, point an OpenAI-compatible SDK at https://api.atptoken.ai/v1, and set model to "glm-5-1". See the Quickstart on this page and the docs.
- What are the context and capabilities of GLM-5.1?
- Capability flags (thinking, tools, vision) follow the gateway model catalog — treat the catalog visible to your key as operational truth. Context is shown only when we have a reliable source. Vendor: Z.ai.
- Who can use GLM-5.1 on ATP?
- Only models on a project’s allowlist can be called with that project’s key (match the API id). Organization → workspace → project governance, per-request logs, and credit budgets are managed in the ATP Console.
