Price comparison

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

Billing	L4	L40S	Difference
On-demand	$0.89 /GPU/hr from $0.32	$1.50 /GPU/hr from $0.38	41% cheaper on L4
Reserved	$0.53 /GPU/hr from $0.32 (36 mo)	$1.11 /GPU/hr from $0.57 (1 mo)	53% cheaper on L4
Spot	-- /GPU/hr from $0.13	$0.90 /GPU/hr from $0.47

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 spot on the L4: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
