Company
xAI is the artificial intelligence company founded by Elon Musk, developer of the Grok large language model family. In physical AI, xAI's Grok serves as the conversational and reasoning layer of Tesla's Optimus humanoid, paired with Tesla's FSD-derived neural networks in a dual-brain architecture. The same Grok-plus-Tesla-compute pattern underpins the "Digital Optimus" software-agent initiative announced in 2026. Tesla announced a 2 billion dollar investment in xAI in 2026, formalizing the technology integration between Musk's AI and robotics ventures.
