Who to follow
64 accounts — the researchers building the models, the practitioners who explain how, and the labs themselves. Names, bios and follower counts are pulled live from the X API, so this list corrects itself when an account moves or disappears.
The people actually building the models. Follow these for signal before it becomes news.
