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 | Massed Compute | |
|---|---|---|
| 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; prepaid balance with $5 minimum threshold |
| Payment model | Prepaid credit balance with burn rate and runway | Prepaid balance with automatic recharge |
| Free credits | not stated | Referral credit 3% of referred spend; coupon codes |
| Egress | not stated | Free |
| Uptime SLA | not stated | 99.999% claimed on product page; no SLA document found |
| Regions | 8 regions: US East/Central/West, Canada, EU West, EU East, India South, Asia-Pacific | US regions (e.g. us-central-3); locations not named |
Neither site tells you whether you get credits when it breaks, how fast support answers, whether a commitment auto-renews or how long you have to dispute a bill. We looked on both and record the absence rather than filling it in — if you need any of it, ask before you commit.
