The honest brief
Runpod
Serverless GPU inference billed by the millisecond and scaling to zero, so idle endpoints cost nothing unlike fixed GPU rentals.
- Serverless auto-scaling inference
- Sub-200ms cold starts
- Secure and Community Cloud GPU tiers
- On-demand Pods and clusters too
- Community Cloud less reliable/secure
- GPU availability varies
- Self-managed model serving
Vast.ai
Marketplace pricing: independent hosts compete, so GPUs (incl. H100s) often run well below first-party clouds like AWS or GCP.
- Often the cheapest GPUs via marketplace
- Per-second billing, $5 minimum
- On-demand, spot, and reserved options
- Large catalog of GPU types
- Host quality and reliability vary
- Not a managed inference platform
- Interruptible instances can be reclaimed
