Elon Musk says SpaceX’s massive corpus of world-class engineering data will be added to the supplemental training of xAI’s 2T run, excluding material blocked by ITAR.
He says the data will dramatically improve Grok’s engineering capabilities. The post also quotes a SpaceX Build user comparing Grok Build and Codex on complex tasks, saying Grok Build is winning trust for higher accuracy and less hand-holding, especially in aerospace-heavy math, science, and data work.
