This one, according to the Information, is the first SpaceXAI model built jointly with the AI startup Cursor, which SpaceX is currently in the process of acquiring for $60 billion. A version of the Grok AI model that shipped in May did at least incorporate data from Cursor, according to Elon Musk. Last month, Elon Musk posted on X that his company’s latest unreleased model, Grok 4.5, was being beta tested behind the scenes at SpaceX and Tesla. He said its performance was comparable to some unspecified version of Claude Opus—Anthropic’s tier just below the controversially powerful Fable. Grok 4.5, based on our 1.5T V9 foundation model, with Cursor data added in supplemental training, is now in private beta at SpaceX & Tesla. Early evals show performance close to, perhaps exceeding Opus. RL is continuing to significantly improve the model, and the Grok Build… — Elon Musk (@elonmusk) June 28, 2026   The Information’s report is more specific, saying the model is being compared internally to Claude Opus 4.8, along with OpenAI’s GPT 5.5—the latest GPT model to be released, although GPT-5.6 exists, and is expected to be released soon. Cursor founder Michael Truell made an announcement last month of a model Cursor was working on that would supposedly compete with Frontier models from Anthropic and OpenAI. He referred to this as the “next phase of the company” without directly stating the model was a project directly linked to SpaceXAI at the time. SpaceXAI is a rebranding of the company formerly known as xAI. It was announced Monday.    Explore more on these topics cursor Elon Musk SPACEX spacexai Copied! our newsletters Subscribe and interact with our community, get up to date with our customised Newsletters and much more.
