Credits

Top up the prepaid credit wallet, check your balance, pay a plan with credits, and browse your credit transactions.

The credit wallet is prepaid balance that pays for every usage-based product — inference, GPUs, fine-tuning, databases, and agents. Top up from the console and the credits land in your balance right away.

How the wallet works

The wallet is a single running balance, denominated in dollars. Every usage-based action you take — an inference request, a GPU-hour of instance time, a fine-tuning job, a database-month, an agent-minute — deducts its cost from that balance the moment it’s metered. There’s no separate wallet per product: one balance covers all of them.

The credit lifecycle

Credits flow in a loop: top up the walletusage-based products deduct per uselow-balance alerts as the balance runs down → top up again to keep usage-based products running.

Top up and check your balance

  1. 1
    Open the credits page
    From Account → Billing, open the AI Credits tab to see your current balance.
  2. 2
    Start a top-up
    Click Add credits, enter a dollar amount, and confirm. This opens a Stripe checkout page for that amount.
  3. 3
    Complete checkout
    Finish payment on the Stripe page. When it succeeds, you're returned to the console and the credits are already reflected in your balance.

Pay a plan with credits

If your wallet has enough balance, the plan checkout screen offers Pay with credits as an alternative to a card — choosing it settles the plan cost straight from your wallet instead of charging Stripe.

Browse credit transactions

The AI Credits tab also lists your credit ledger — every top-up and every deduction, in order, so you can see exactly what drew down your balance and when.

Ledger entryWhat it means
Top-upA Stripe checkout you completed, or the one-time signup bonus, adding to the balance.
DeductionA usage-based charge — an inference call, a GPU-hour, a database-month, an agent-minute — drawn from the balance the moment it's metered.
RefundBalance returned to the wallet, for example from a refunded deployment bill.

Low-balance warnings

As the balance runs down, NevTan surfaces a low-balance warning on the Billing screen before it reaches zero, so there's time to top up or turn on auto-pay before anything is interrupted. The warning tracks the same number shown on the AI Credits tab — there's no separate threshold to configure.

What happens at zero

Without auto-pay, a zero balance blocks new usage-based actions in the console — starting an inference call, launching a GPU instance, kicking off a fine-tuning job — until you top up again. With auto-pay on and a card on file, NevTan charges the saved card automatically the moment more balance is needed, so usage carries on without you having to notice the warning at all.

Tip
Enable auto-pay with a saved card to keep credits topped up automatically instead of hitting a zero balance mid-workload.
Important
Usage-based actions — starting an inference call, launching a GPU, kicking off a fine-tuning job — fail once your balance hits zero unless auto-pay is on.
