Price comparison

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

Billing	H100	RTX 3090 Ti
On-demand	$3.50 /GPU/hr from $1.80	-- /GPU/hr from $0.19
Reserved	$3.29 /GPU/hr from $1.53 (1 mo)	No reserved listings
Spot	$2.39 /GPU/hr from $1.29	-- /GPU/hr from $0.10

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