Credit system
QuantaCloud uses a prepaid credit model. You load credits into your account and they’re consumed as you use GPU instances. All prices are in USD. There are no contracts or minimum commitments.How charges work
GPU deployments
- You’re charged for the first hour upfront when you deploy.
- After that, billing continues hourly.
- If your balance is insufficient to cover the next hour, the deployment is automatically stopped.
Low balance warnings
When your active deployments would exhaust your remaining balance soon, you’ll receive a low-balance warning email so you can add credits before anything is interrupted.Payment methods
Adding credits
Go to Billing in the sidebar. You can:- Click a quick amount button (25, 100, 500)
- Enter a custom amount
Saved cards
Under Payment Methods, you can:- View all saved payment methods
- Mark a card as default (used for auto top-up)
- Add new cards
- Remove cards (must keep at least one if auto top-up is active)
Auto top-up
Keep your balance funded automatically:- Enable Auto Top-Up on the billing page
- Set a threshold — when your balance falls below this amount, a top-up is triggered
- Set a top-up amount — how much to add each time
