| On-demand | $8.25 /GPU/hr from $4.99 | $0.99 /GPU/hr from $0.54 | 88% cheaper on RTX 6000 Ada |
| Reserved | $6.25 /GPU/hr from $4.25 | $1.13 /GPU/hr from $0.55 (1 mo) | 82% cheaper on RTX 6000 Ada |
| Spot | $5.20 /GPU/hr from $2.99 | -- /GPU/hr from $0.27 |
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 RTX 6000 Ada: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
