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
