Billing

Pay for GPU time by the hour from a prepaid USDC balance. What you are charged, when billing stops and how idle instances stop themselves.

Osarai charges for GPU time, not tokens. While an instance runs, its hourly price comes out of your balance; requests themselves cost nothing extra, however many tokens they use.

How the price is set

The deploy page shows the hourly price of each GPU before you deploy. It is the price of the machine, storage included, plus Osarai's margin, minus any voucher you apply. The price is fixed when you deploy: later changes never reprice a running instance.

Billing starts when the machine is rented (setup included) and stops when you stop the instance. Deploys that fail before they become Ready are not charged.

Topping up

Open Billing, pick a network and send USDC to your deposit address. The balance updates once the network confirms the transfer. Any amount works; a deploy needs at least one hour of the instance's price in your balance.

Stopping and idle instances

  • Press Stop on the instance page to stop paying right away.
  • Instances stop themselves after a stretch without requests (60 minutes by default; change it per instance). Every API request counts as activity.
  • When your balance runs out, running instances get a short grace period and then stop. Requests then answer 503 until you deploy again.

Vouchers and rewards

Vouchers take a percentage off the hourly price of one deploy, for that instance's whole life. You get one when you sign up, through invite links, the daily lucky wheel and the points shop. A deploy uses your best voucher automatically.
