Price comparison

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

Billing	A4000	RTX PRO 4000
On-demand	$0.20 /GPU/hr from $0.07	-- /GPU/hr from $0.20
Reserved	$0.18 /GPU/hr from $0.06 (3 mo)	-- /GPU/hr from $0.24 (1 mo)
Spot	-- /GPU/hr from $0.06	-- /GPU/hr from $0.14

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 A4000 and on-demand, reserved and spot on the RTX PRO 4000: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
