These are not the same product. A GPU specialist and a peer marketplace differ in who your counterparty is, which is why the rates below can be far apart without either being wrong. The prices are comparable; what stands behind them is not.
The 8 cards both of them rent, cheapest published per-GPU on-demand rate each. Dearest first.

Per GPU per hour, on-demand list prices as each provider last published them. Rates exclude tax and vary by region; a cheaper rate is not the same machine, the same network or the same support.
| GPU.ai | Vast.ai | |
|---|---|---|
| Billing granularityOn short jobs this outweighs the rate: an hour minimum on a 90-second run costs more than a 30% dearer per-second rate. | Per second | Per second |
| Minimum commitment | $5 minimum deposit, no term | $5 minimum to start |
| Payment model | Prepaid credit balance with burn rate and runway | Prepaid credits; optional auto top-up |
| Egress | not stated | Priced per byte by each host |
| Regions | 8 regions: US East/Central/West, Canada, EU West, EU East, India South, Asia-Pacific | 40+ data centres worldwide |
Neither site tells you whether your data trains their models, an uptime SLA, whether you get credits when it breaks or whether a commitment auto-renews. We looked on both and record the absence rather than filling it in — if you need any of it, ask before you commit.
