Vast.ai GPU pricing

Marketplace model, so there is no single rate to record. Page states: prices 'set by supply and demand across 40+ data centers', 68+ GPU types, per-second billing, and three tiers - On-Demand (guaranteed uptime, no interruptions), Interruptible ('50%+ cheaper', preemptible, may be reclaimed), Reserved ('Up to 50% Off', 1/3/6 month terms, volume discounts, contact sales). The 'Live GPU Prices' grid renders client-side from an API and carried no numbers in the extracted HTML, so no concrete price_usd is taken from this page. Recorded for the structural point: Vast is a spot/interruptible-first market, the cheapest credible route to consumer GPUs, and the wrong place to look for an H100 HSA with guaranteed capacity.
