Vast.ai logo Vast.ai Pricing Details

Hosts set their own rates. Compute is billed per second from prepaid credits. Storage charges continue while an instance is stopped, and bandwidth fees vary by host.

  • On-demand: Fixed rates for the offer's maximum duration.
  • Interruptible: Bid for capacity. Instances pause if you're outbid or an on-demand renter takes the machine.
  • Reserved: Prepay for a fixed term, with larger discounts for longer commitments.

Heads up: A provider's own page may quote a different figure, for example on tax, region or a promotion. A monthly-only plan shows a derived hourly rate. Plan figures take each provider's closest match to a common setup. Verify before provisioning. More on how we price.
