The honest brief
Lambda
1-Click Clusters give self-serve, contract-free access to multi-node B200/H100 training clusters that elsewhere require procurement cycles.
- Single GPUs up to superclusters
- Self-serve multi-node clusters
- No long-term hyperscaler contracts
- Deep NVIDIA collaboration
- No free tier
- In-demand GPUs can sell out
- Fewer managed services than hyperscalers
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
When to pick which
Both cover GPU compute.
Pick Vast.ai if you need Model inference / serving.
