Price comparison

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

Billing	B300	T4G
On-demand	$8.99 /GPU/hr from $4.99	-- /GPU/hr from $0.42
Reserved	$5.47 /GPU/hr from $4.25	-- /GPU/hr from $0.18 (36 mo)
Spot	$6.17 /GPU/hr from $4.08	No spot listings

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 reserved on the T4G: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
