Assuming I was okay with the political exploits of Elon and his companies:

Grok was supposed to be the unbiased model, that is: regurgitate everything it has read. Obviously all data has bias, even all of the data at once, but the sales pitch was that you would get that unfiltered. At least in open source models, this has been shown to improve the competence of the model.

Then this happened: https://futurism.com/artificial-intelligence/grok-describes-...

So not only has bias been introduced, but they are happily biasing it for trivial reasons. So now the model needs to be competitive in exactly the same way that others are: on benchmarks (which are still not a solved problem).

But, I (and many others) disagree with how Elon has behaved politically and don't want to hand money over to him, so all of that is a hypothetical.
