Elon Musk-funded xAI is skipping Grok 3.5 and releasing Grok 4 after Independence Day in the United States, and it could be the best model from the company. Grok 3.5 was originally supposed to be a huge leap from the previous models, but xAI later made several changes to the training model, and that warranted a new version.

AI launches Grok 4 on July 9, 2025! Discover its advanced reasoning, coding (Grok 4 Code), multimodal support, and real-time web search capabilities.

Elon Musk launched Grok 4 and Grok 4 Heavy. These xAI models are meant to challenge the speed, accuracy, and vision of OpenAI’s GPT-5 and Google’s Gemini.
