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.

| 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 minute | Per GPU-hour |
| Minimum commitment | None; prepaid balance with $5 minimum threshold | $25 first payment; no term |
| Payment model | Prepaid balance with automatic recharge | Bank card or bank transfer; PDF invoices by email |
| Free credits | Referral credit 3% of referred spend; coupon codes | Promo codes grant free credits |
| Egress | Free | Free |
| Uptime SLA | 99.999% claimed on product page; no SLA document found | 99.50% for Compute; compensation 10–30% of fees |

Neither site tells you whether a commitment auto-renews, how long you have to dispute a bill 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.
