Shared, not compared today
Both providers quoted these GPUs on-demand within the last 7 days, but at least one quote is not confirmed within 48 hours of the newest read (or is a marketplace floor withheld as too thin), and an unconfirmed price never decides which is cheaper. They return to the table above at the next read that confirms them.
- NVIDIA H100 SXM: Vast.ai: thin market
- NVIDIA H200: Vast.ai: thin market
How this is compared
Cloud GPU rental prices of Modal and Vast.ai, compared per GPU-hour on the GPUs both list. Where a provider has several tiers or regions, its cheapest on-demand rate is used and labelled. Community capacity (RunPod Community Cloud) and marketplace floors are shown only where a provider has nothing else, and never decide which is cheaper.
