I was talking about why would I use a Grok specific version of this instead of one that I can switch models.

What if Grok models become horrible or they increase the pricing of the subscriptions now you have to migrate off. Instead you could just use the open source version that allows you to choose your providers and switch cost is just the time to switch those providers.

I assume he meant an actual use case. Its architecture alone is not a reason to use it.
