Google Gemini API Credits Guide
Separate Gemini API free access, account billing plans, prepaid balances, and eligible promotional offsets.
Where to start
A Gemini budget should name the project, billing account, model, and access tier. Treat free access as a bounded evaluation, and make the transition to paid usage explicit. For multimodal workflows, measure actual media and token components rather than estimating from visible text alone.
Google’s billing guide distinguishes Prepay and Postpay arrangements and describes prerequisites for applying eligible promotional Cloud credits. Account-specific setup matters.
Before you commit a budget
- Check the project’s assigned billing plan in the official account.
- Verify eligible models, quotas, and data-use conditions.
- Record promotional-credit requirements separately from purchased funds.
Run a measured pilot
Choose a fixed set of realistic tasks and define what makes an answer usable. Record usage, elapsed time, unsuccessful attempts, and any extra work needed to finish. Keep a separate estimate of the ordinary operating cost when a free allowance or promotion is involved.
Review the chosen account’s current terms and limits before increasing traffic. Test your application’s stop and recovery behavior with a bounded workload, and name the person who can inspect billing and pause execution.
