What is GPU Spot Pricing?
GPU spot instances use unused cloud capacity at discounts of 60–90% compared to on-demand pricing. The tradeoff: cloud providers can reclaim instances with little notice (typically 30 seconds warning). For fault-tolerant workloads like batch inference, training, and CI/CD, spot pricing dramatically reduces GPU costs.
RoofRun monitors prices from 7 providers every 30 minutes and surfaces the cheapest RTX 4090 prices so you don't have to check each provider manually.
