Price comparison

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

Billing	RTX A6000	K80
On-demand	$0.75 /GPU/hr from $0.40	-- /GPU/hr from $0.90
Reserved	$0.48 /GPU/hr from $0.26 (6 mo)	-- /GPU/hr from $0.04 (24 mo)
Spot	-- /GPU/hr from $0.33	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 spot on the RTX A6000 and 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.
