# Basic Model Configuration

Parameters that apply to all Mindee model types (Extraction, Split, Crop, etc).

Inference parameters control:

* which model to use
* server-side processing options

### Use an Alias

The optional `alias` field lets you attach your own identifier to a request as a free-form string.

For example, an internal document ID, reference number, or database key.

It is echoed back unchanged in both the job and result responses, making it straightforward to correlate API results with your own records.

Aliases are not unique in Mindee, you can use the same alias value multiple times.
