GPU specialist against peer marketplace, priced against each other on the 5 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.
GPU.ai is cheaper on 5 of the 5 cards both of them rent, by a median of 17%.
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 5 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 | Spheron | |
|---|---|---|
| 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 minute |
| Minimum commitment | $5 minimum deposit, no term | None on dedicated or spot |
| Payment model | Prepaid credit balance with burn rate and runway | Prepaid credits, USD; enterprise invoicing on request |
| Egress | not stated | Network bandwidth included in the hourly rate |
| Uptime SLA | not stated | 99.9% |
| Regions | 8 regions: US East/Central/West, Canada, EU West, EU East, India South, Asia-Pacific | North America, Europe, Asia Pacific |
Neither site tells you whether a commitment auto-renews, how long you have to dispute a bill, whether private networking exists or how much warning you get before maintenance. We looked on both and record the absence rather than filling it in — if you need any of it, ask before you commit.

Of the cards both rent, GPU.ai starts at $0.65 per GPU-hour and Spheron at $0.78.
No. GPU.ai is a GPU specialist — an operator whose whole business is renting these cards. Spheron 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.
