Hmm, I read the situation a little differently. Grok is not a slouchy model. It’s not the best, but it’s not the worst. X currently has one source of proprietary data, Twitter, and grok is by far the best at all the things you might imagine there - today’s zeitgeist, who’s saying what, current news, etc.
Cursor adds in a large corpus of proprietary coding data — I think this is actually fairly hard to acquire right now, because claude and codex are so good.
I bet there’s enough talent at the Grok team to work with the cursor team and data to get something good out the door.
That said, I don’t track Grok’s engineering leads — I’m not sure who’s currently around, and who is not.
