A new chapter is unfolding in the world of technology: SpaceXAI, formerly known as xAI, in collaboration with AI startup Cursor, is preparing to release a revolutionary artificial intelligence model — Grok 4.5. This is the first joint product created under the strategic partnership between the two companies, and it promises to radically change the landscape of the large language model (LLM) market.
Closed Testing and Initial Results
Rumors about the emergence of a new powerful AI model have been circulating for some time. Recently, Elon Musk confirmed that the latest non-public version of the neural network, named Grok 4.5, underwent closed beta testing within SpaceX and Tesla. According to him, the model's performance is comparable to the capabilities of Claude Opus from Anthropic — one of the most advanced systems on the market.
"Grok 4.5, based on our 1.5T V9 foundational model, with data cursor linked to universal education, is now in private beta at SpaceX & Tesla. Most importantly, it shows continuous execution, breaking Opus benchmarks," Musk noted, adding that the reinforcement learning (RL) process continues to significantly improve the model.
Comparison with Market Leaders
However, fresh internal data suggests even higher performance metrics. According to sources, within the company, the new algorithm is directly compared with the cutting-edge Claude Opus 4.8 model, as well as the latest release from OpenAI — GPT 5.5. These comparisons indicate that Grok 4.5 could become a serious competitor to current industry leaders.
History of Collaboration and Strategic Goals
Previous steps towards technological convergence occurred back in the spring, when the May version of Grok partially incorporated data arrays from Cursor. Cursor startup founder Michael Truwell previously stated that they were working on a secret model capable of competing on equal terms with the best products from OpenAI and Anthropic. At that time, he called this project "the next phase for the company," but did not directly confirm that the development was being carried out in Musk's interests and with his direct funding.
The current integration is part of the tech giant's global strategy. The appearance of the joint product coincided with major structural changes in Elon Musk's business. In particular, an official global rebranding of the company xAI was announced — it now officially operates under the new name SpaceXAI.
Unified Superintelligence Ecosystem
It is under this brand that developers plan to develop a unified superintelligence ecosystem, combining the computing power of aerospace, automotive, and neural network enterprises of the controversial billionaire. Such an approach will allow creating synergy between different business directions, strengthening the potential of each of them.
Thus, the launch of Grok 4.5 becomes not just another step in the development of artificial intelligence, but an important stage in the formation of a new technological paradigm, where boundaries between industries are blurred, and innovations become the driving force of progress.
