Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | GB300 | Vera Rubin | Difference |
|---|---|---|---|
| On-demand | -- /GPU/hr from $18.00 | No on-demand listings | |
| Reserved | -- /GPU/hr from $8.09 | -- /GPU/hr | |
| Spot | Sold out | 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. No median for on-demand and reserved on the GB300 and reserved on the Vera Rubin: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
