An internal memo shows Elon Musk's xAI has seconded Jack Garabedian from
SpaceX’s Starlink unit to lead model training for the Grok chatbot, replacing
engineer Diego Pasini. Garabedian, a Starlink engineer at SpaceX since 2021,
will head the 'human data team' of several hundred specialists training Grok
across domains including finance and science. Pasini and Garabedian did not
respond to requests for comment; SpaceX and xAI representatives also did not
reply.
