Grok (chatbot)

Grok is a generative artificial intelligence chatbot developed by xAI. It was launched in November 2023 by Elon Musk as an initiative based on the large language model (LLM) of the same name. Grok is integrated with the social media platform X, formerly known as Twitter, and has apps for iOS and Android. The bot is named after the verb grok, coined by American author Robert A. Heinlein in his 1961 science fiction novel Stranger in a Strange Land to describe a form of understanding. The bot, which is marketed as providing "unfiltered answers", has generated various controversial responses in its history.
