Price comparison

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

Billing	A40	RTX A6000	Difference
On-demand	$1.05 /GPU/hr from $0.40	$0.56 /GPU/hr from $0.35	46% cheaper on RTX A6000
Reserved	-- /GPU/hr from $0.61 (24 mo)	$0.54 /GPU/hr from $0.26 (6 mo)
Spot	-- /GPU/hr from $0.31	$0.34 /GPU/hr from $0.20

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.
