ELON MUSK: Grok 5 will train on all SpaceX data, which could make it "by far the best engineer".
"We're making rapid progress on Grok because Grok 4.5 was a huge improvement. And we have Grok 4.6 coming out probably next week. And then Grok 4.7 is about three or four weeks from today. And we expect the cadence of AI development to improve dramatically.
"And then, with Grok 5, which should be out before the end of this year, we will be incorporating the entire corpus of SpaceX data. Basically, all the data that SpaceX has ever produced, which is a tremendous amount over the course of a quarter century, will be incorporated into Grok training. And we think this will make Grok by far the best engineer."
