Gemini 3.1 Pro (Preview)

Every completed request debits project credits at these list rates. Failed requests are not billed.

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.
