# Vast.ai vs Hyperstack

Canonical: https://inetgeek.com/compare/vast-ai-vs-hyperstack/

Every value below is read from Vast.ai's and Hyperstack's own documentation. See https://inetgeek.com/methodology/ for how.

## At a glance

| Criterion | Vast.ai | Hyperstack |
| --- | --- | --- |
| 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. | $3.20 per hour for H100 SXM 80GB on demand. The NVLink variant is $2.60 and the PCIe H100 is $2.50. |
| 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. | $0.15 per hour for an A4000 with 16GB; the A100 SXM 80GB is $1.60. |
| Largest GPU offered | 192GB per GPU on B200, from $4.38 an hour with a median of $7.50. | 288GB per GPU on B300 at $7.40 an hour; B200 at 192GB is $6.00. |

## Where they differ

### H100 SXM, per GPU-hour

- Vast.ai: 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))
- Hyperstack: $3.20 per hour for H100 SXM 80GB on demand. The NVLink variant is $2.60 and the PCIe H100 is $2.50. ([source](https://www.hyperstack.cloud/gpu-pricing))

### Cheapest GPU, per hour

- Vast.ai: 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))
- Hyperstack: $0.15 per hour for an A4000 with 16GB; the A100 SXM 80GB is $1.60. ([source](https://www.hyperstack.cloud/gpu-pricing))

### Largest GPU offered

- Vast.ai: 192GB per GPU on B200, from $4.38 an hour with a median of $7.50. ([source](https://vast.ai/pricing))
- Hyperstack: 288GB per GPU on B300 at $7.40 an hour; B200 at 192GB is $6.00. ([source](https://www.hyperstack.cloud/gpu-pricing))

## Which should you choose?

Pick Vast.ai if 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.

Pick Hyperstack if Steady European workloads that can commit — reserved H200 at $2.79 against $3.99 on demand is the clearest published discount in this set, and egress is free.

Consider something else: Vast.ai — 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.

Consider something else: Hyperstack — Billing is per minute rather than per second, so very short jobs round up in a way they do not at RunPod.

## Documented by only one

- Pricing model: Vast.ai: 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.
- Egress over allowance: Hyperstack: Free. Egress and ingress traffic are not charged; a public IP address costs $0.00672043 per hour.
- Billing granularity: Hyperstack: Per minute, with enterprise-scale contracts negotiated separately.
- Reserved pricing: Hyperstack: Published reserved rates rather than a percentage: H200 SXM falls from $3.99 on demand to $2.79 reserved, about 30% below.
