Vast.ai
A marketplace that brokers spare capacity from many hosts, so prices are the lowest around — but reliability and location vary by host. A real-time search and bid/interruptible mode let you trade price against guarantees.
On-demand USD prices are indicative snapshots from June 2026 for orientation only — they are not live. Spot/community and committed-use rates are often 30–70% lower. Always confirm on the provider's pricing page before committing.
