Price comparison

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

Billing	MI355X	RTX 3070
On-demand	$8.04 /GPU/hr from $5.99	-- /GPU/hr from $0.05
Reserved	-- /GPU/hr from $4.29	No reserved listings
Spot	-- /GPU/hr from $3.44	-- /GPU/hr from $0.04

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 MI355X and on-demand and spot on the RTX 3070: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
