Price comparison

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

Billing	A40	L40S	Difference
On-demand	$0.66 /GPU/hr from $0.34	$1.50 /GPU/hr from $0.38	56% cheaper on A40
Reserved	-- /GPU/hr from $0.61 (24 mo)	$1.10 /GPU/hr from $0.60 (12 mo)
Spot	-- /GPU/hr from $0.27	$1.06 /GPU/hr from $0.40

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 A40: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
