According to Business Insider, Elon Musk revealed on X that SpaceX has reassigned "dozens" of top Starlink and Starship engineers, alongside members of the Cursor team, to work on improving the Grok model family. Musk stated that the latest version, Grok 4.5, is already in private testing within Tesla and SpaceX, and that SpaceX plans to release a new "trained-from-scratch" model every month this year. This is the latest sign of SpaceX's full-scale push into AI, following a major restructuring of xAI earlier this year that saw several co-founders depart.
Shifting aerospace engineering talent to AI model development underscores the strategic importance SpaceX places on Grok. The Starship and Starlink programs rely heavily on AI for orbital calculations, communication optimization, and autonomous control, giving these engineers cross-domain experience that could bring unique compute scheduling and infrastructure optimization capabilities to Grok. Musk emphasized on X that "the pace of improvement in both models and training pipelines is accelerating significantly," thanks to top engineers dedicating more time to AI work.
