Price comparison

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

Billing A800 RTX 4000 Ada Difference
On-demand -- /GPU/hr from $1.18 $0.49 /GPU/hr from $0.20
Reserved No reserved listings -- /GPU/hr from $0.18 (3 mo)
Spot No spot listings -- /GPU/hr from $0.15

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 on the A800 and reserved and spot on the RTX 4000 Ada: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
