Price comparison

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

Billing	A100	K80
On-demand	$1.81 /GPU/hr from $0.40	-- /GPU/hr from $0.90
Reserved	$1.60 /GPU/hr from $0.40 (1 mo)	-- /GPU/hr from $0.04 (24 mo)
Spot	$0.89 /GPU/hr from $0.17	No spot listings

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 reserved on the K80: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
