Price comparison

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

Billing	B300	RTX 4070
On-demand	$9.15 /GPU/hr from $4.99	-- /GPU/hr from $0.15
Reserved	$5.78 /GPU/hr from $4.25	No reserved listings
Spot	$5.72 /GPU/hr from $4.08	-- /GPU/hr from $0.07

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 on-demand and spot on the RTX 4070: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
