Elon Musk recently revealed on social platform X that SpaceX has reassigned "dozens" of top engineers from its core Starlink and Starship programs to focus full-time on upgrading its Grok AI model. According to Musk, this move has significantly accelerated the pace of progress for the SpaceX AI team in model training and hardware adaptation. The latest version, Grok 4.5, is now in private testing within both Tesla and SpaceX.
This personnel shift is the latest signal that SpaceX is going all-in on AI. Musk said that after transferring key talent from Starlink and Starship, "the improvement speed of the model and development framework has increased notably." Additionally, SpaceX’s $60 billion acquisition this month of AI coding startup Cursor—whose engineers have joined the development of Grok’s new foundation model, with part of its training data sourced from Cursor—further underscores the push. Musk also announced that SpaceX plans to release a brand-new model trained from scratch each month starting this year, aiming to catch up with competitors like OpenAI and Google.
