【#Tech24H】Musk posted on X on June 28 that Grok 4.5 is built upon the self-developed V9 base model with 1.5 trillion parameters and underwent supplementary training using Cursor datasets. The model is now undergoing internal testing within SpaceX and Tesla. Early evaluation results indicate its performance matches, and is expected to exceed, the Opus model. RLHF continues to greatly boost the model’s capabilities, while the scheduling framework for Grok is being improved with daily iterations. Musk also disclosed that SpaceX will launch a series of brand-new models trained completely from scratch on a monthly basis for the rest of this year.
