Cloud GPU Showdown: RunPod vs Vast.ai for AI Inference
When your local hardware can't handle a model, cloud GPUs fill the gap. RunPod and Vast.ai are the two leading platforms for AI inference. Here's how they compare.
Pricing Comparison (April 2026)
| GPU | RunPod | Vast.ai |
|---|---|---|
| RTX 4090 (24GB) | $0.44/hr | $0.20-0.35/hr |
| RTX A6000 (48GB) | $0.76/hr | $0.40-0.60/hr |
| A100 80GB | $1.64/hr | $0.80-1.20/hr |
| H100 80GB | $3.29/hr | $2.00-3.00/hr |
Vast.ai typically offers lower prices because it's a decentralized marketplace where hardware owners set their own rates. RunPod provides more consistent pricing and reliability.
When to Use Each
Choose RunPod when: You need reliability, consistent uptime, and serverless deployment options. Best for production workloads.
Choose Vast.ai when: You're optimizing for cost and can tolerate some variability in availability. Best for experimentation and batch processing.
Getting Started
Both platforms require only a credit card to start. No long-term commitments. You can spin up a GPU, run your model, and shut it down in minutes.
