In a post on X, Chaplot said he will work closely with Musk and teams at both companies “to build superintelligence,” as SpaceX and xAI integrate AI more closely with hardware.
Chaplot said SpaceX and xAI bring together physical and digital intelligence under a leader who deeply understands hardware. He described the culture as “high-agency” with “frontier-scale resources,” saying it creates the chance to build something truly unique. He also said he is grateful for the journey that brought him there.
Musk reposted the update and welcomed Chaplot to the team.
Before this role, Chaplot worked in academia, Big Tech, research labs, and AI startups, focusing on robotics, embodied AI, and large language models (LLMs). He was part of the founding team at French startup Mistral AI, helping develop models like Mistral 7B and Mixtral, and also worked at Thinking Machines Lab, which builds large-scale training infrastructure and tools for foundation models.
Devendra Singh Chaplot is an experienced AI researcher who was previously a founding member at Thinking Machine Labs, an AI startup founded by former OpenAI CTO Mira Murati. Earlier, he was part of the founding team at Mistral AI, which is backed by Dutch semiconductor company ASML. Chaplot also worked at Facebook’s AI research team starting in 2018 and, before entering the AI industry, was a research associate at Samsung.
“I’m excited to keep advancing the fields I’ve been passionate about for years, from robotics research to building AI models as part of the founding teams at Mistral and TML. Both experiences were incredible and helped shape how I think about building intelligence from the ground up,” said Devendra Singh.
Last month, Musk reshuffled the management of xAI ahead of a planned initial public offering (IPO), which could become one of the largest ever after the company’s merger with SpaceX.
