Price comparison

Median price per GPU per hour by billing type, with the cheapest listing under it.

Billing GB300 RTX 3060 Difference
On-demand -- /GPU/hr from $18.00 $0.07 /GPU/hr from $0.05
Reserved On request -- /GPU/hr from $0.24 (3 mo)
Spot Sold out -- /GPU/hr from $0.03

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 on-demand on the GB300 and reserved and spot on the RTX 3060: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
