Price comparison

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

Billing	A40	T4	Difference
On-demand	$0.65 /GPU/hr from $0.28	$0.64 /GPU/hr from $0.15	Within 5%
Reserved	-- /GPU/hr from $0.61 (24 mo)	$0.43 /GPU/hr from $0.20 (36 mo)
Spot	-- /GPU/hr from $0.27	$0.26 /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 reserved and spot on the A40: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
