# Vast.ai

Canonical: https://inetgeek.com/gpu/vast-ai/

GPU marketplace where independent hosts set prices, published as live floor and median rates across 40+ data centres.

## Who it suits

Price-sensitive training and batch inference that can tolerate a marketplace — the median H100 rate is well under half what the managed clouds charge, and interruptible capacity goes lower still.

Consider something else if There is no single price to plan against: rates move with supply, the host is not Vast itself, and an interruptible instance can be reclaimed mid-run.

## What the documentation says

### Pricing

- Pricing model: A marketplace rather than a cloud: prices are set by supply and demand across more than 40 data centres, and the same card can be rented on demand, interruptibly, or reserved. Rates move continuously, which is why every figure here carries a 7-day re-verification window rather than the category's 30. ([source](https://vast.ai/pricing), read 2026-09-06)

### GPU

- H100 SXM, per GPU-hour: Median $2.16 per hour for H100 SXM 80GB, with a floor of $1.33 from the cheapest host. Vast is a marketplace — the floor is one host's offer at one moment and the median is what the market is actually charging, so both move without anyone announcing anything. This figure is a snapshot, not a rate card. ([source](https://vast.ai/pricing), read 2026-09-08)
- Cheapest GPU, per hour: Floor and median vary by card and by the hour; H100 PCIe runs from $1.87 with a median of $2.67, and H200 from $1.97 with a median of $4.24. The H200 floor now sits below the H100 PCIe median, which is the kind of inversion a marketplace produces and a rate card cannot. ([source](https://vast.ai/pricing), read 2026-09-08)
- Largest GPU offered: 192GB per GPU on B200, from $4.38 an hour with a median of $7.50. ([source](https://vast.ai/pricing), read 2026-09-08)
