| On-demand | $8.62 /GPU/hr from $4.99 | $0.69 /GPU/hr from $0.20 | 92% cheaper on T4 |
| Reserved | $5.47 /GPU/hr from $4.25 | $0.43 /GPU/hr from $0.20 (36 mo) | 92% cheaper on T4 |
| Spot | $5.99 /GPU/hr from $4.08 | -- /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 T4: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
