Price comparison

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

Billing	RTX A6000	RTX 4000 Ada	Difference
On-demand	$0.56 /GPU/hr from $0.35	$0.51 /GPU/hr from $0.17	8% cheaper on RTX 4000 Ada
Reserved	$0.48 /GPU/hr from $0.26 (6 mo)	-- /GPU/hr from $0.16 (6 mo)
Spot	$0.47 /GPU/hr from $0.13	-- /GPU/hr from $0.12

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 RTX 4000 Ada: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
