Compute is charged for each second a container runs, settled every 10 seconds, and stops when the container does. Every model has its own per-million-token rate; MiMo V2.6 Flash is the reference the billing service publishes. Other metered work, such as image and video generation, bills at its own rate. The Search, Maps and Mail APIs draw on a separate API balance: see api.kaer.ai/pricing.

Hard caps
The meter stops. You don't overspend.
Every account runs on a prepaid credit balance. Metered work stops when it reaches zero, and usage never bills your card after the fact. Add credit by hand, or turn on automatic top-up with a monthly cap.
- Prepaid: usage draws on credit you already have
- Metered work stops at a zero balance
- Automatic top-up stays off until you turn it on
- Automatic top-up stops at the monthly cap you set
Credits, answered.
Where do these rates come from?
From the billing service. This page reads the same rate card the meter charges from, and the raw card is public at kaer.ai/api/billing/rates. The usage page in your settings breaks your own spend down by day and by model.
How is compute billed?
By the second while a container runs, at its size's hourly rate, settled every 10 seconds. Nothing is charged once it stops.
Does unused credit roll over?
Plan credits reset when your cycle renews. Top-up and bonus credits carry over until you use them, unless an expiry was stated when you got them, and the soonest-expiring credit is spent first.
What happens if I hit zero?
Metered work stops with a notice to top up, until you add credit or your plan renews. Automatic top-up, if you turned it on, adds credit within your monthly cap. You're never billed a surprise overage.
Can I set a custom spend cap?
Yes. Automatic top-up has a monthly purchase cap set in billing settings. When that cap is reached, no more top-ups occur and work pauses at a zero balance.
Can I get more credits each month?
Yes. Add 1,000-credit packs to any paid plan at $10 a month each, or top up once whenever you need to.
