Vast.ai vs Hyperstack
A comparison of Vast.ai and Hyperstack built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
- 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.
3 sourced criteria separate them:
- 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.
- Hyperstack: $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
- 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.
- Hyperstack: $0.15 per hour for an A4000 with 16GB; the A100 SXM 80GB is $1.60.
- Largest GPU offered
- Vast.ai: 192GB per GPU on B200, from $4.38 an hour with a median of $7.50.
- Hyperstack: 288GB per GPU on B300 at $7.40 an hour; B200 at 192GB is $6.00.

Which should you choose?
Choose 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.

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