Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | A30 | B100 | Difference |
|---|---|---|---|
| On-demand | $0.76 /GPU/hr from $0.33 | No on-demand 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.
