Price comparison

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

Billing	L40S	RTX 3090 Ti	Difference
On-demand	$1.50 /GPU/hr from $0.55	$0.27 /GPU/hr from $0.19	82% cheaper on RTX 3090 Ti
Reserved	$1.10 /GPU/hr from $0.60 (12 mo)	-- /GPU/hr from $0.22 (6 mo)
Spot	$1.05 /GPU/hr from $0.74	-- /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 reserved 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.
