# Parameterized Models

The Model specification allows parameters to be passed to the loaded model to allow customization. For example:

```yaml
# samples/models/choice1.yaml
apiVersion: mlops.seldon.io/v1alpha1
kind: Model
metadata:
  name: choice-is-one
spec:
  storageUri: "gs://seldon-models/scv2/examples/pandasquery"
  requirements:
  - mlserver
  - python
  parameters:
  - name: query
    value: "choice == 1"
```

This capability is only available for MLServer custom model runtimes. The named keys and\
values will be added to the model-settings.json file for the provided model in the`parameters.extra` Dict. MLServer models are able to read these values in their `load` method.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.seldon.ai/seldon-core-2/user-guide/models/parameterized-models.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
