[Feature Request] Built-in Grok-4 support

[MozgC]

🥰 Feature Description

Hello,
Currently I was able to use grok-4 by adding a custom xAi provider, however, can we please add this grok-4 out of the box?

🧐 Proposed Solution

Grok-4 should be available in the list of model after installing an application or when using a web version.
Here's official documentation on the API:
