The honest brief
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
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
