Price comparison

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

Billing L4 RTX 3090 Difference
On-demand $0.88 /GPU/hr from $0.27 $0.19 /GPU/hr from $0.10 78% cheaper on RTX 3090

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 reserved and spot on the RTX 3090: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
