Grok 4

The Grok 4.5 model will be released to the public tomorrow. It is as intelligent as Opus but at a lower cost. On June 28, Elon Musk revealed that SpaceXAI’s latest flagship model Grok 4.5 began a limited private preview. At that time, the model was already undergoing preview testing in the SpaceX and Tesla teams. Early internal evaluation showed that the intelligent level of Grok 4.5 is equivalent to the Claude Opus series model. Now Elon Musk has finally announced that Grok 4.5 is ready for testing and will be available to the global public. Specifically, it will be released on July 9, 2026, the same as GPT-5.6. Elon Musk confirmed that SpaceXAI Grok 4.5 will be launched to the global public tomorrow, and the early launch is due to strong positive feedback from many customers during the testing phase, so the SpaceXAI team feels it is ready for release. Grok 4.5 is developed based on the V9 base model with 1.5T (one trillion) parameters, with data from the Cursor AI coding tool added in supplementary training. Elon Musk said that Grok 4.5 provides Claude Opus-level intelligence, but has faster response speed, better token usage efficiency, and more importantly, Grok 4.5 is also cheaper to use. However, the specific model performance needs to be evaluated after it is opened tomorrow. via cnBeta.COM - Chinese industry information website (author: source: bluedot.com)
