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

Modal

Define GPU infra in Python decorators with 2-4s cold starts — no YAML, Dockerfiles, or managed-stack lock-in.

  • Python-decorator infra, no YAML/Dockerfiles
  • Scale-to-zero, pay only when running
  • Scales to hundreds of GPUs
  • Free monthly starter credits
  • SDK lock-in; migrating means rewriting
  • No managed vLLM/TensorRT setup
  • Costs climb under heavy usage
  • Billing hard to predict
