Voltage Park

H100 training runs where price per hour is the whole decision.

high portability Portable. The workload is standard enough to move to another vendor without a rewrite.

What you are buying

Business model
Purpose-built GPU cloud. Owns or leases its own datacentre capacity and sells it directly.
How you reach it
You get the physical machine. Maximum control, and every layer above it is yours to run.
Accelerators
H100 at scale
Regions
US
Pricing model
Hourly and reserved, published, deliberately low.
Getting started
Self-serve.
Capacity
Thousands of H100s, single-part focus.
Ownership
Private, non-profit-affiliated ownership structure.

Verified 2026-09-09. Fields reading “not published” are exactly that — we do not estimate a figure a vendor withholds.

The counterparty

Unusual ownership means unusual incentives — read them rather than assuming the venture-backed default.

A multi-year GPU commitment is a credit decision wearing a cloud contract. This is the section no benchmark covers and the one that decides what happens to your workload in 2028.

The catch

Essentially one part. When H100 is not what you need, this is not a supplier.

The economics

Among the lowest published H100 rates from a genuine datacentre operator.

No rate is quoted on this page on purpose. Published list prices at this layer move weekly and essentially nobody signing a real contract pays them. Dated, sourced figures live in the GPU cost calculator, where the cheapest and dearest published on-demand price for the identical H100 sit 5.6× apart.

The layers underneath this one

Whatever you rent here is a chip in a building that needs power. In 2026 megawatts, not silicon, are the binding constraint on the whole industry — a frontier rack draws 120–200 kW against a 2026 average near 27 kW, and the US interconnection queue exceeds 2,600 GW.
