Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | A100 | RTX 4500 Ada | Difference |
|---|---|---|---|
| On-demand | $1.81 /GPU/hr from $0.89 | No on-demand listings | |
| Reserved | $1.60 /GPU/hr from $0.66 (24 mo) | No reserved listings | |
| Spot | $1.20 /GPU/hr from $0.67 | No spot listings |
Heads up: A provider's own page may quote a different figure, for example on tax, region or a promotion. A monthly-only plan shows a derived hourly rate. Medians are across providers, one vote each, so a large catalog does not outweigh a small one. Verify before provisioning. More on how we price.
