Elon Musk’s SpaceXAI and code editor Cursor plan to release their first jointly built AI model as soon as Wednesday, according to an internal memo.
Key Takeaways
SpaceXAI and Cursor plan to ship their first joint AI model as soon as Wednesday, per a staff memo.The model was trained on SpaceX’s Colossus cluster, scaling to roughly 1 million H100-equivalent GPUs.SpaceX, which holds 18,712 BTC, exercised its option to buy Cursor after a $60 billion deal set in April.The model is set to ship inside both Cursor, the popular AI code editor, and Grok Build, SpaceXAI’s developer-facing product. Training has been running on SpaceX’s Colossus supercomputer, a cluster scaling to roughly one million H100-equivalent graphics processing units (GPUs).
“SpaceX has exercised the option to acquire Cursor in an all-stock transaction with the goal of building the world’s most useful AI models. For the past few months, SpaceXAI has been jointly training a model with Cursor, which will be released in Cursor and Grok Build soon.”
From Partnership to PowerhouseSpaceX acquired Musk’s separate AI venture xAI in February 2026 in an all-stock deal valuing the combined entity at roughly $1.25 trillion, uniting rockets, satellites, and frontier AI models under one roof. The combined company then went public, hitting a $2.1 trillion valuation on its June 12 Nasdaq debut, a listing that also made Musk the world’s first trillionaire on paper.
In any case, the joint model enters a market where OpenAI, Anthropic, and Google ship frequent upgrades, and where coding assistants have become the industry’s most closely watched commercial battleground.
