Elon Musk calls Grok 4.5 a “solid workhorse” after a Tim Sweeney praise
The post quotes Tim Sweeney saying Grok 4.5 is very good for “vibe math” in programming language theory and more fun to use than Claude and web-based tools that are slower or more naggy.
Elon Musk then responds with a blunt endorsement: “Grok 4.5 is a solid workhorse.”
The post does not add new technical details about the model, but it is a notable public signal about perceived model quality and usability from two high-profile figures.
