Price comparison
GPU.ai Pricing
Billed per second, from the moment an instance reaches SSH-ready until it is stopped, with no minimums and no idle reservation fees. On-demand rates vary by region and upstream provider, and the platform routes each launch to the cheapest one with stock. Reserved capacity is quote-only and arranged with sales.
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.
