A cloud vision API charges per image processed, which looks negligible in a demo and can become a real line item at production volume. Self-hosting a model trades that per-call cost for fixed infrastructure cost — the right choice depends on volume.
The break-even framework
- Estimate your monthly image volume and multiply by the API's per-image price to get a monthly cloud cost.
- Compare against the cost of a GPU instance (or a free-tier one, if your latency needs allow) running a self-hosted equivalent model continuously.
- Below the break-even volume, cloud APIs win on simplicity; above it, self-hosting wins on cost, assuming you can maintain it.
The maintenance cost that's easy to forget
Self-hosting means you own model updates, scaling, and uptime — real ongoing work a cloud API absorbs for you. Factor engineering time into the comparison, not just infrastructure dollars.
