General-purpose cloud against peer marketplace, priced against each other on the 3 GPUs both of them rent. Published per-GPU on-demand rates as each provider last stated them, with what their own pages say about billing, commitment and egress beside the numbers.
Vast.ai is cheaper on 3 of the 3 cards both of them rent, by a median of 79%.
These are not the same product. A general-purpose cloud 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 3 cards both of them rent, cheapest published per-GPU on-demand rate each. Dearest first.
| GPU | Exoscale | Vast.ai | Difference |
|---|---|---|---|
| NVIDIA RTX PRO 6000 Blackwell 96GB | $2.00/hr | $1.33/hr | 33% cheaper on Vast.ai |
| NVIDIA RTX A5000 24GB | $1.14/hr | $0.24/hr | 79% cheaper on Vast.ai |
| NVIDIA RTX 3080 Ti 12GB | $0.79/hr | $0.12/hr | 84% cheaper on Vast.ai |
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.
| Exoscale | 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, flat rate across all zones | Per second |
| Minimum commitment | None on-demand; volume plans set one deliberately | $5 minimum to start |
| Payment model | Pay only for what you consume | Prepaid credits; optional auto top-up |
| Egress | Outbound transfer charged; rates on the calculator | Priced per byte by each host |
| Regions | European zones including Zurich (CH-DK-2) and Frankfurt (DE-FRA-1) | 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.

NVIDIA RTX PRO 6000 Blackwell 96GB, NVIDIA RTX A5000 24GB, NVIDIA RTX 3080 Ti 12GB — 3 in total, on published per-GPU on-demand rates.
Of the cards both rent, Exoscale starts at $0.79 per GPU-hour and Vast.ai at $0.12.
No. Exoscale is a general-purpose cloud — a hosting company where GPUs sit beside the VPS products, on the same account and billing. Vast.ai is a peer marketplace — a stranger whose machine the platform vets to some degree. Reliability, bandwidth and how long the machine stays online vary by host, not just by price. The rates are comparable; what stands behind them is not.
