Book excerpt: Grok is a new AI chatbot created by Elon Musk's xAI, which aims to offer a unique AI experience by providing witty and logical answers to user queries. The name Grok is derived from Robert A. Heinlein's 1961 science fiction novel "Stranger in a Strange Land," where it means "to drink" but is generally understood as having deep empathy or intuition with something. The AI is designed to have a bit of wit, a rebellious streak, and a willingness to tackle controversial or "spicy" questions that other AI systems might avoid. Grok is currently available to select X platform users in the US as part of the early access program. The company claims that Grok has surpassed "all other models in its compute class," including ChatGPT-3.5 and Inflection-1, but it is still outperformed by bots with larger data troves. The goal of xAI is to build artificial intelligence that advances humanity's understanding of the universe. With a team of former employees from OpenAI, DeepMind, and other prominent organizations, xAI is actively hiring for various roles as it continues to develop its technology.
