Price comparison
Vast.ai Pricing
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.
