Is renting GPUs for inference worth it vs an API?

Is it worth it? To decide whether renting GPUs for inference beats an API, you have to weigh what the AI costs against what it saves or earns. This page helps teams considering rented GPUs put both sides on the same page and see the payback, not just the invoice.

Why this isn't trivial

The part people underestimate: rented GPUs cost per hour whether busy or idle, so low utilization can make them pricier than per-token APIs. In practice the biggest savings come from keeping GPUs highly utilized or using them only for steady load, so it is worth modelling before you commit.

How it's calculated

We estimate this by comparing per-hour GPU cost divided by throughput against the API's per-request price. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.

Frequently asked questions

What kills GPU ROI?+

Idle time — you pay for the hour regardless of how many requests you served.

When do rented GPUs win?+

At steady, high throughput where per-request cost drops below the API.

Are these prices up to date?+

Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
