Head-to-head
RunPod vs Vast.ai: which one in 2026?
Runpod is a GPU cloud from Runpod Inc. with pods, serverless inference and clusters at published hourly rates, and Vast.ai is a marketplace from Vast.ai Inc. where independent hosts rent out GPUs. The practical difference is a priced catalog you can budget from versus a live market you have to check.
Verdict
Runpod ranks above Vast.ai because a buyer can read the rates, see the serverless and cluster products, and find a named privacy contact before spending anything. Vast.ai is the better fit when cost per hour is the only goal and the work tolerates interruption, since the marketplace and Interruptible tier are built for that. Neither page states training use or SOC 2 status, so regulated workloads need written answers from either vendor first.
RunPod and Vast.ai side by side
| RunPod | Vast.ai | |
|---|---|---|
| Price entry | $0.59 per hour (A40 or RTX A6000 pod, 48 GB) | Market-set hourly rates; no fixed list price |
| How the capacity is sourced | Runpod lists Secure Cloud and Community Cloud tiers, with 31 regions across the US, Europe, Asia and Australia. | Vast.ai describes itself as a marketplace for renting and hosting GPU compute, so capacity comes from independent hosts. |
| Published GPU rates | Hourly rates are on the page, for example H100 SXM at $3.99 Secure and $2.69 Community, RTX 4090 at $0.89 and $0.34. | The pricing page showed no dollar rates in the text we read; it points to live price cards and a calculator. |
| Billing and instance types | Pods are metered per second with no commitment. Spot capacity can be evicted, and reservations discount long commitments. | On-Demand, Interruptible (described as 50%+ cheaper) and Reserved for 1, 3 or 6 months, with per-second billing. |
| Inference serving | Serverless workers scale from zero, with Flex and Active types, billed from worker start to full stop. | No managed serverless product appeared on the pages we read; the focus is renting instances. |
| Multi-GPU and large jobs | Clusters of up to 64 GPUs with shared storage, plus reserved clusters through sales for larger contracts. | Reserved terms of 1, 3 or 6 months with volume discounts; cluster size limits were not stated on the pages read. |
| Developer tooling | API, CLI and SDKs, GitHub and CI/CD integration, and Docker images pulled from registries such as Docker Hub or ECR. | An OpenAPI-described API, a CLI and a Python SDK, with a separate hosting path for people who supply GPUs. |
| Data handling and terms | The privacy policy names a Data Protection Officer and an EU/UK representative; hosting region and training use are not stated. | The privacy policy says data may be stored in the United States; terms let prices change at any time and credits expire. |
| Free access | The pricing page states no free plan or trial; you pay per second once a pod starts. | The pricing page mentions no free plan or trial; credits are prepaid and spent credits are final. |
Where each one wins
RunPod wins on
- Rates for pods, serverless, clusters and storage are printed on the page, so a budget can be drafted before signing up.
- Serverless inference with scale-to-zero workers is a product of its own, not something you assemble on rented instances.
- Cluster sizes up to 64 GPUs with shared storage are stated, which helps multi-node training plans.
Vast.ai wins on
- An Interruptible tier priced at 50%+ below on-demand suits fault-tolerant jobs that can restart when capacity is reclaimed.
- The marketplace model, with 68+ GPU types across 40+ data centers, gives a wide spread of hardware from independent hosts.
- Reserved terms of 1, 3 or 6 months with up to 50% off give a short commitment path without a custom contract.
Which to pick
Pick RunPod if
You need predictable, published hourly rates, serverless inference endpoints, or a multi-GPU cluster from one vendor with a documented regional footprint.
Pick Vast.ai if
You run restartable batch work, want to compare live offers from many hosts, or may want to rent out your own GPUs on the same platform.

Frequently asked questions
Is Runpod or Vast.ai cheaper for an RTX 4090 or H100?
Runpod prints its rates: RTX 4090 at $0.89 per hour Secure and $0.34 Community, H100 SXM at $3.99 and $2.69. Vast.ai showed no dollar figures in the pricing text we read, so compare against the live price cards on the day you rent. Marketplace rates move with host supply.
Does Vast.ai offer serverless endpoints like Runpod Serverless?
The Vast.ai pages we read described On-Demand, Interruptible and Reserved instances, with no serverless product mentioned. Runpod Serverless scales workers from zero with Flex and Active types and bills per second from worker start. Check Vast.ai's documentation if you need request-based autoscaling.
What happens to an Interruptible instance on Vast.ai when capacity is reclaimed?
Vast.ai describes Interruptible as preemptible capacity that may be reclaimed, priced at 50%+ below on-demand. Terms published no interruption notice period that we found. Checkpoint your training state often, or choose On-Demand, which the page says has guaranteed uptime and no interruptions.
Can I keep EU data off United States servers with Runpod or Vast.ai?
Neither policy we read commits to a hosting region. Runpod says data may move to the United States or other countries through service providers, and Vast.ai says information may be stored in the United States. Ask each vendor in writing which location your workload would use.
