Price comparison

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

Billing	RTX 3080	RTX 4000 SFF Ada	Difference
On-demand	$0.14 /GPU/hr from $0.10	-- /GPU/hr from $0.50
Spot	-- /GPU/hr from $0.06	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 3080 and on-demand on the RTX 4000 SFF Ada: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
