Grok is a generative artificial intelligence chatbot developed by xAI, Elon Musk's AI firm. It is based on a large language model (LLM) of the same name and was initially launched in November 2023. Grok is designed to be maximally truthful, useful, and curious, distinguishing itself with a notable "sense of humor" and a unique personality in its responses. One of Grok's key differentiators is its direct access to real-time information from the X platform (formerly Twitter), allowing it to provide up-to-date answers and engage in current discussions. It excels in real-time research, open-ended discussions, and structured problem-solving, making it a versatile AI assistant. The model has seen significant advancements through its versions, particularly with Grok 3, which introduces enhanced reasoning capabilities, a much larger context window, and advanced features like DeepSearch and video processing. Grok is available as a standalone conversational AI chatbot on web browsers and dedicated mobile applications, and is also integrated within the X platform. Developers can access Grok's capabilities through a robust API.
