Price comparison

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

Billing	MI350X	RTX 4000 SFF Ada
On-demand	No on-demand listings	-- /GPU/hr from $0.42

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 MI350X and on-demand on the RTX 4000 SFF Ada: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
