|---|---|---|---|
| On-demand | $1.39 /GPU/hr from $0.08 | $0.47 /GPU/hr from $0.33 | 66% cheaper on RTX 4090 |
| Reserved | $1.04 /GPU/hr from $0.22 (24 mo) | $0.52 /GPU/hr from $0.33 (6 mo) | 51% cheaper on RTX 4090 |
| Spot | -- /GPU/hr from $0.07 | $0.33 /GPU/hr from $0.16 |
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 P100: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
