SpaceXAI Launches Grok 4.5, an 'Opus-Class' Coding Model at Under Half the Price, Built With Newly-Acquired Cursor
About This Episode
Reuters reported on July 8, 2026 that Elon Musk's newly-rebranded SpaceXAI launched Grok 4.5, publicly available July 9. It is the company's first model since the xAI-to-SpaceXAI rebrand and the first trained with data from Cursor, the code editor SpaceX bought for $60 billion. Musk calls it 'Opus-class' but priced at less than half of Anthropic's Opus, and it is aimed at coding and agentic work rather than casual chat.
Our Take
The same coding tool developers rely on (Cursor) was folded into the model now built to do their jobs cheaper, as a single Musk-owned empire ships an 'Opus-class' coder at half the price and pushes the cost of cognitive work toward zero.
