Grok is the conversational AI assistant from xAI, the company founded by Elon Musk, available at grok.com, in dedicated apps and integrated into the X social network. The model answers questions, writes text and code, analyzes images and pulls real time information from the web and from X, which sets it apart from assistants limited to training data.
Features include DeepSearch for in depth research, extended reasoning modes for complex problems, image generation and conversation memory. It serves both personal use (research, writing, studying) and developers, who can access the models through the xAI API.
There is a free tier with usage limits and paid subscriptions (the SuperGrok line and X Premium plans) that unlock newer models, higher limits and advanced features.
