TensorDock

TensorDock operates as a marketplace of independent GPU hosts who compete on price rather than a single provider with a rate card. It lists around 45 GPU models across 100+ locations in 20+ countries, from entry-level consumer cards to H100 SXM5s, with KVM virtualization, root access, Windows support, per-second billing, and no ingress or egress fees. Servers run on a prepaid balance and are deleted automatically when it hits zero.

The marketplace model produces striking prices: published floors run about $0.12/hr for entry consumer cards, $0.35/hr for an RTX 4090, $1.80/hr for an A100 SXM4, and $2.25/hr for an H100 SXM5, though the same GPU carries different rates by host, location, and redundancy. In March 2025 Voltage Park acquired TensorDock, making the two former alternatives a single option.

The caveats are marketplace-shaped: rates float with supply and demand, host hardware and network quality vary, and prepaid auto-deletion can surprise teams running long jobs. Spot instances run 50-80% cheaper for fault-tolerant work. It suits inference and batch training where cost-per-query compounds, not latency-sensitive distributed training.
