Add an indicator to the /model list that a model is not available (for your current plan), not only when you try selecting it.

Summary

Having these models in the list confused me and made me thing the application was bugged, maybe greying out the model names in the list or smth could fix this.

Expected Behavior

Maybe greying out the model names in the list, or not showing them, maybe a divider between accessible and non-accessible models, or some other way to instantly indicate that you don't own it.

Actual Behavior

It shows all the models in white with no difference if you have access to it or not, only when you try selecting it does it say you don't have it.

Steps to reproduce the issue

use /model
look for models you don't own
