Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B300 | L4 | Difference |
|---|---|---|---|
| On-demand | $8.99 /GPU/hr from $4.99 | $0.81 /GPU/hr from $0.33 | 91% cheaper on L4 |
| Reserved | $5.46 /GPU/hr from $4.25 | $0.52 /GPU/hr from $0.32 (36 mo) | 90% cheaper on L4 |
| Spot | $6.17 /GPU/hr from $4.08 | -- /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 L4: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
