Four questions
No parameter anxiety.
The primary flow asks only for API spend band, hosted model, traffic shape, and hard constraints.
API-first by default
9 out of 10 typical workloads should stay on the API.
At typical scale, hosted API providers compete hard enough on price that self-hosting usually loses — and that is before counting your time. But exceptions exist.
Exception traits
Check if any of these apply.
- Sustained high-volume API spend
- Strict data residency or air-gap requirements
- Predictable batch or steady GPU utilization
- Small open-weight substitute is acceptable
- Latency requirements API providers cannot meet
Serving modalities
Self-hosting is not one thing.
Exception results compare API, managed endpoints, serverless GPU, VMs, batch GPU, and owned hardware.
Advanced path
Open-weight details stay available.
If you already know the model and cloud, inspect the precomputed GPU × quantization × shape matrix.
