Section 1
The premise
Modal lets you write a Python function, decorate it for GPU, and deploy as a serverless endpoint. Magical for spiky workloads, mathematically painful for steady high-utilization ones.
What AI does well here
- Deploy GPU-backed functions and webhooks from pure Python
- Scale to zero between requests without managing infrastructure
- Run batch inference jobs across hundreds of GPUs on demand
What AI cannot do
- Eliminate cold starts on huge models without keep-warm tricks
- Match dedicated-cluster latency for ultra-low-latency inference
- Be the cheapest option at sustained high QPS

Section 3
The premise
Modal lets teams run serverless GPU jobs by decorating Python functions, removing the need to operate a cluster for batch and on-demand inference.
What AI does well here
- Spin GPU workloads from Python without DevOps overhead
- Scale concurrent jobs elastically with per-second billing
- Snapshot environments for reproducible runs
What AI cannot do
- Replace dedicated infrastructure for sustained 24x7 high-throughput inference
- Substitute for capacity planning when scarce GPU types are required
- Guarantee identical pricing economics versus reserved-capacity alternatives
