Price comparison

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

Billing	A40	V100	Difference
On-demand	$0.85 /GPU/hr from $0.49	$0.97 /GPU/hr from $0.08	12% cheaper on A40

Spot	No spot listings	$0.25 /GPU/hr from $0.08

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 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.
