Billing	A4000	L40S	Difference
On-demand	$0.20 /GPU/hr from $0.07	$1.50 /GPU/hr from $0.55	87% cheaper on A4000
Reserved	$0.18 /GPU/hr from $0.06 (3 mo)	$1.10 /GPU/hr from $0.60 (12 mo)	84% cheaper on A4000
Spot	-- /GPU/hr from $0.06	$1.05 /GPU/hr from $0.74

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 spot on the A4000: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
