Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.

| Reserved | No reserved listings | $0.58 /GPU/hr from $0.38 (12 mo) | |
| Spot | No spot listings | -- /GPU/hr from $0.29 |
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 spot on the A30: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
