Side-by-side H100, A100, and RTX 4090 pricing, billing models, and trade-offs between two of the most popular GPU rental platforms.
📅 Data verified: 2026-06-13
RunPod and Vast.ai both offer rentable GPUs, but they package and price them differently. RunPod combines a managed Secure Cloud with a cheaper Community Cloud and bills per second, with H100 pricing at $1.99/hr (PCIe) to $2.69/hr (SXM) and A100 80GB from $1.19/hr. Vast.ai is a decentralized marketplace that bills per minute and can be cheaper on raw hourly rates, with H100s from about $1.87/hr, A100 80GB from about $0.67/hr, and RTX 4090s from about $0.20/hr.
| Feature | RunPod | Vast.ai |

| Billing | Per-second | Per-minute |
| H100 Pricing | $1.99/hr (PCIe) – $2.69/hr (SXM) | from ~$1.87/hr (PCIe) |
| A100 80GB Pricing | from $1.19/hr | from ~$0.67/hr |
| RTX 4090 Pricing | from ~$0.34/hr (Community Cloud) | from ~$0.20/hr |

💡 Pricing reflects publicly listed on-demand rates as of 2026-06-13 and may vary by region, GPU availability, or change over time. Always confirm current pricing on the provider's site before committing.
For short-lived inference jobs, bursty experiments, or teams that want a more structured platform, RunPod is the better pick because per-second billing minimizes idle waste and it offers both Secure Cloud and lower-cost Community Cloud options; its RTX 4090 pricing starts around $0.34/hr and H100s run $1.99/hr to $2.69/hr depending on PCIe vs SXM. For budget-first researchers or longer training runs who can tolerate host variability, Vast.ai is the better pick because its marketplace pricing is often lower, with A100 80GB from about $0.67/hr versus RunPod from $1.19/hr, and RTX 4090s from about $0.20/hr. If your priority is the absolute lowest hourly rate and you are comfortable with fluctuating availability and no enterprise SLA, Vast.ai usually has the edge.
Usually no on raw hourly price. RunPod lists H100s at $1.99/hr for PCIe and $2.69/hr for SXM, while Vast.ai H100 PCIe pricing starts around $1.87/hr. RunPod can still make sense for very short jobs because it bills per second, whereas Vast.ai bills per minute.
RunPod is generally the better fit for short jobs because per-second billing reduces the cost of setup and idle time. It also offers serverless GPU endpoints for inference autoscaling and a managed Secure Cloud alongside Community Cloud options. Vast.ai bills per minute and can be cheaper overall, but reliability and network speed vary by host.
Yes, based on the listed starting prices. Vast.ai shows RTX 4090s from about $0.20/hr and A100 80GB from about $0.67/hr, while RunPod starts around $0.34/hr for RTX 4090 on Community Cloud and $1.19/hr for A100 80GB. The tradeoff is that Vast.ai pricing and availability fluctuate live with marketplace supply and demand.
In 2026, the easiest pricing mistake is comparing only the hourly GPU rate. Vast.ai listings still vary a lot on included egress, while RunPod workflows can look cheap until you pull checkpoints, logs, or generated media out of the platform. Before choosing, estimate your monthly outbound GB and add it to the GPU bill—especially for fine-tuning, video generation, or frequent model syncs. A $0.10–$0.20/hr price advantage disappears fast if you move hundreds of GB per week off the instance.
