Musk says SpaceX engineering data will be used to train Grok further
mark_k · x · 2026-07-21
Elon Musk says SpaceX’s large corpus of world-class engineering data, excluding material blocked by ITAR, will be added during supplemental training for Grok’s upcoming 2T run. He claims that this should substantially improve Grok’s engineering capabilities.
The key implication is that xAI is now explicitly leaning on SpaceX’s internal engineering data as a training advantage, which could materially affect Grok’s performance on technical tasks.
