Price comparison

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

Billing	A800	RTX 3080
On-demand	-- /GPU/hr from $1.18	$0.15 /GPU/hr from $0.11
Reserved	No reserved listings	-- /GPU/hr from $0.12 (3 mo)
Spot	No spot listings	-- /GPU/hr from $0.06

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 on the A800 and reserved and spot on the RTX 3080: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
