Simon Willison’s Weblog

Musk’s latest Grok chatbot searches for billionaire mogul’s views before answering questions. I got quoted a couple of times in this story about Grok searching for tweets from:elonmusk by Matt O’Brien for the Associated Press.

“It’s extraordinary,” said Simon Willison, an independent AI researcher who’s been testing the tool. “You can ask it a sort of pointed question that is around controversial topics. And then you can watch it literally do a search on X for what Elon Musk said about this, as part of its research into how it should reply.”

Willison also said he finds Grok 4’s capabilities impressive but said people buying software “don’t want surprises like it turning into ‘mechaHitler’ or deciding to search for what Musk thinks about issues.”

“Grok 4 looks like it’s a very strong model. It’s doing great in all of the benchmarks,” Willison said. “But if I’m going to build software on top of it, I need transparency.”

Matt emailed me this morning and we ended up talking on the phone for 8.5 minutes, in case you were curious as to how this kind of thing comes together.
