Price comparison

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

Billing	K620	RTX 4000 Ada
On-demand	No on-demand listings	$0.51 /GPU/hr from $0.20
Reserved	No reserved listings	-- /GPU/hr from $0.18 (3 mo)
Spot	No spot listings	-- /GPU/hr from $0.13

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.
