Hey @edwin-truthsearch-io, thank you for the contribution!

Can you double check the models info? I left some comments on it.

Thank you!

[edwin-truthsearch-io]

I enabled console debugging locally, and I could see that the changes to the modelInfo were getting reflected in the UI, so this change is done.

@daniel-lxs I rebased the to main and added a changeset. Is it good to go now?

Thank you!

This looks good but I have no way of testing it since I don't have an xAI account.

cc: @hannesrudolph idk if you do.
