Methodology
What the numbers on this site mean, and what they don't.
What GPU Index tracks
We publish hourly snapshots of GPU cloud list prices and, where we can observe it, whether capacity appears available. Historical data is kept — we don't overwrite past observations.
How fresh is the data?
Numbers on this site refresh about once per hour (UTC). The timestamp at the top of each page shows when the latest snapshot was computed. Expect up to one hour of lag.
Prices
All prices are shown as USD per GPU-hour so you can compare across providers. We normalize GPU names (e.g. H100-SXM-80GB) because each provider labels hardware differently.
Prices come from a mix of public provider catalogs, marketplace listings, and published rate cards. A low listed price does not guarantee you can rent at that rate right now.
Availability
Not every provider publishes capacity information. Where we have a signal, we show it; where we don't, we label it unknown rather than guessing.
- Green — capacity looked available in most checks over the past 24 hours
- Yellow — mixed signals
- Red — rarely looked available recently
- Unknown — we track list prices but have no availability signal for this GPU
Cheapest available only includes offers where we saw a recent availability signal. Cheapest listed includes all published prices, including catalog entries that may not be rentable on demand.
Limitations
- List prices may exclude spot discounts, reserved pricing, credits, or enterprise agreements.
- Marketplace and catalog data can lag reality by minutes to hours.
- Availability indicators are observational, not a guarantee of successful provisioning.
- Coverage and accuracy improve over time as we add providers and history accumulates.
