HomeMusk Unveils Grok 4.5 Advancements as SpaceX and Tesla Begin Internal Training
Elon Musk recently revealed on his social media that Grok 4.5, the newest large language model, has entered private testing within SpaceX and Tesla’s internal systems. This step marks the transition of the model from theoretical research to complex, real-world applications.
According to Musk, Grok 4.5 is built on the V9 architecture, featuring 1.5 trillion parameters. To boost its reasoning and processing power, developers integrated data from the popular AI coding assistant Cursor during training. This focused approach aims to significantly enhance code generation accuracy and performance on intricate tasks.
Early performance metrics for Grok 4.5 are promising. Evaluations suggest its overall capabilities rival, and in certain areas may exceed, Anthropic’s flagship model, Claude Opus. The team continues refining the model using reinforcement learning (RL) and updating the Grok Build benchmark to ensure robustness under stress.
Musk also signaled an acceleration in SpaceX’s large model development. He announced that SpaceX will release a new model every month for the rest of the year, with all models trained from scratch. This rapid iteration highlights Musk’s ongoing commitment to AI and suggests the industry is entering an era of intense, high-frequency competition.
