# What is model API cost?

Model API cost is the provider’s invoice for embeddings, transcription, vision, and chat. It is usually the surprise next to hosting.

## How it works {#how-it-works}


- A computed column calls a hosted model.
- That vendor bills tokens, seconds, or images.
- A local model moves the cost to your hardware instead.

## What it is not {#what-it-is-not}

It is not the database subscription, and it is not GPU rental on a machine you already own.

## model API cost: this, and the thing it is confused with {#comparison}

|  | This | Not this |
| --- | --- | --- |
| Who bills | The model vendor | The database, for the call itself |
| Trigger | A column that calls the model | Storing the row |
| Avoid a repeat | Cache the column | Hope |

## Where Pixeltable fits {#where-pixeltable-fits}

Pixeltable does not mark up those calls. The key is yours. Cached columns skip repeat calls when the row has not changed.
