xAI recruits three heavyweight talents within a week, Mistral co-founder Chaplot joins to participate in Grok model training

Gate News: On March 16, Mistral AI co-founder Devendra Singh Chaplot announced that he has joined xAI and SpaceX, where he will directly participate in training the Grok large model and work on integrating digital intelligence with physical hardware. Chaplot posted this news on the X platform on March 14, and Elon Musk retweeted and replied, “Welcome to xAI.”

Chaplot is a leading figure in the field of embodied AI. During his time at Mistral AI, he directly led the training of core models such as Mistral 7B, Mixtral 8x7B, and Mistral Large, and spearheaded the development of the multimodal model Pixtral 12B. Subsequently, he became a founding team member of Thinking Machines Lab, founded by former OpenAI CTO Mira Murati.

Adding to this, Andrew Milich and Jason Ginsberg, who previously joined from AI programming tool Cursor, xAI has recruited three heavyweight talents within a week, forming a strategic combination of “model layer reconstruction + product layer development.” This stands in stark contrast to the ongoing departure of co-founders previously reported: xAI is experiencing talent loss while simultaneously bringing in new blood on a large scale.
