Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | K620 | L4 | Difference |
|---|---|---|---|
| On-demand | No on-demand listings | $0.88 /GPU/hr from $0.32 | |

| Spot | No spot listings | $0.29 /GPU/hr from $0.13 |
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.
