SpaceXAI teams up with Cursor for a new AI model

SpaceXAI is about to launch its first AI model built with Cursor, which is said to be as good as Anthropic's Claude or OpenAI's GPT. Even though the $60 billion deal to buy Cursor isn't done yet, their teams are already working together.

Elon Musk said Grok 4.5, based on a 1.5 trillion-parameter model, is being tested inside his companies. The CEO of Cursor added that the model is being trained from scratch at SpaceXAI's Colossus data center to compete with top AI companies.
