SpaceX Deploys Dozens of Engineers to Grok AI

What did Elon Musk announce about SpaceX engineers and Grok?

SpaceX has deployed "a few dozen" top Starlink and Starship engineers to work on its Grok AI model. Elon Musk made the announcement in a post on X on Sunday. "The SpaceXAI cadence of model and harness improvement is speeding up tremendously, particularly due to a few dozen of the top Starlink/Starship engineers shifting much of their time to AI," Musk wrote.

Who else is working on Grok alongside the SpaceX engineers?

Musk also said staff from Cursor are pitching in. Cursor is an AI coding startup that SpaceX agreed to buy for $60 billion. Musk said the new Grok foundation model was partly trained on Cursor training data. As part of the deal, SpaceX granted Cursor access to its supercomputers to help train Grok.

What is Grok 4.5 and where is it available now?

Grok is the AI model family developed under xAI, Elon Musk's AI startup, now merged with SpaceX. Musk posted that Grok 4.5, the latest version, is currently in private beta at Tesla and SpaceX. He also said SpaceX plans to release new models "trained from scratch" every month this year.

Why is SpaceX pushing so hard on AI right now?

Business Insider reports that Grok has lagged rival AI models from OpenAI and Anthropic, especially on coding. Musk wrote in March that xAI was "being rebuilt from the foundations up." The last of xAI's 11 cofounders departed earlier this year following a sweeping reorganization.

In February, Musk merged xAI with SpaceX. The Cursor acquisition was confirmed shortly after SpaceX's $85 billion IPO earlier this month. SpaceX's investor materials estimated its total addressable market at $28.5 trillion, with AI accounting for $26.5 trillion of that figure.

What is the Cursor acquisition and who leads the company?

Cursor is an AI coding startup led by 25-year-old Michael Truell. SpaceX confirmed its acquisition of Cursor for $60 billion. CNBC reports the deal will help SpaceX compete with rivals like Anthropic and OpenAI, which also offer popular coding tools. The acquisition is a significant moment for the AI coding space more broadly.

Here's what we know so far about the key moves SpaceX has made in AI this year:

What are SpaceX's broader AI ambitions?

Musk has said SpaceX will use proceeds from its IPO to build a network of up to one million orbital data centers. These would be built on Starlink technology and carried into space by Starship. The goal is to train and run increasingly advanced AI models from orbit.

This push into AI models puts SpaceX in direct competition with OpenAI and Anthropic. For context on how rivals are positioning, see how Amazon eyes alternative AI models after Anthropic pricing tensions, and how Anthropic launched Claude for Slack teams. The AI coding and infrastructure race is intensifying across the board.

SpaceX's next confirmed milestone is releasing new Grok models trained from scratch on a monthly basis through the rest of 2026.
