Price comparison

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

Billing	K80	RTX 4080
On-demand	-- /GPU/hr from $0.90	$0.24 /GPU/hr from $0.20
Reserved	-- /GPU/hr from $0.04 (24 mo)	-- /GPU/hr from $0.28 (3 mo)
Spot	No spot listings	-- /GPU/hr from $0.11

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 and reserved and spot on the RTX 4080: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
