| Reserved | $0.18 /GPU/hr from $0.06 (6 mo) | $0.58 /GPU/hr from $0.21 (1 mo) | 3.2x more expensive on RTX 5090 |
| Spot | -- /GPU/hr from $0.07 | -- /GPU/hr from $0.15 |
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 A4000 and spot on the RTX 5090: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
