Grok 4.5, based on our base model 1.5T V9, with Cursor data added in supplemental training, is now in private beta at SpaceX and Tesla. The first evaluations show a performance close to the Opus, perhaps surpassing it.
RL continues to significantly improve the model, and Grok Build…

The Information report is more specific and says that the model is being compared internally to Claude Opus. 4.8along with OpenAI’s GPT 5.5, the latest GPT model released, although GPT-5.6 existsand is expected to be released soon.
Michael Truell, founder of the course made an announcement last month of a model Cursor was working on that was supposed to compete with the Frontier models from Anthropic and OpenAI. He referred to this as the “next phase of the company” without directly stating that the model was a project directly linked to SpaceXAI at the time.
