Elon Musk said on Sunday that SpaceX had deployed "a few dozen" top Starlink and Starship engineers to help overhaul its Grok model, with the "SpaceXAI cadence of model and harness improvement is speeding up tremendously." Engineers from Cursor, the AI coding startup that SpaceX agreed this month to buy for $60 billion, are also working on the new foundation model, which was partly trained on Cursor training data. Musk stated that Grok 4.5, the latest version of the chatbot, is now in private beta at Tesla and SpaceX, and posted that SpaceX would release new models "trained from scratch" every month this year. In February, Musk merged xAI with SpaceX, and the deal to acquire Cursor was confirmed after the rocket company's $85 billion IPO earlier this month. SpaceX granted Cursor access to the company's supercomputers in return for help training Grok.
