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

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 on-demand on the RTX PRO 6000D: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
