Price comparison

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

Billing	B100	H100
On-demand	No on-demand listings	$3.27 /GPU/hr from $1.30
Reserved	No reserved listings	$3.11 /GPU/hr from $1.53 (1 mo)
Spot	No spot listings	$2.00 /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. Verify before provisioning. More on how we price.
