Grok is an intelligent chat model developed by xAI, a company launched by Elon Musk, which has been developed into the latest Grok 4. The model has multimodal capabilities such as real-time search, code execution, and image/video understanding. Recently,"Imagine" image video generation has also been supported for free, and Grok 4 is open to all users, while SuperGrok Heavy provides more performance.
