Price comparison

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

Billing	A40	RTX PRO 4500	Difference
On-demand	$0.65 /GPU/hr from $0.28	$0.82 /GPU/hr from $0.36	21% cheaper on A40
Reserved	-- /GPU/hr from $0.61 (24 mo)	On request
Spot	-- /GPU/hr from $0.27	-- /GPU/hr from $0.28

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 reserved and spot on the A40 and spot on the RTX PRO 4500: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
