About Grok, Your Humorous AI Search Assistant on X

Welcome to the world of Grok, an AI search assistant with a twist of humor and a dash of rebellion. X Premium and Premium+ subscribers have the ability to conduct searches and get answers using Grok, as an enhancement of X's search functions. Grok is here to help you with your search and answers while keeping you entertained and engaged. In this article, we explain what Grok is, how it works, and where you can find it.


What is Grok and how does it work?

Grok is a new enhanced search feature available to X Premium and Premium+ subscribers powered by xAI’s state-of-the-art large language model (LLM) (Grok-1). Inspired by the Hitchhiker's Guide to the Galaxy and JARVIS from Iron Man, Grok is designed to answer almost any question with a touch of wit and humor, while also providing helpful and insightful responses. Grok has a rebellious streak and an outside perspective on humanity, making it a unique and entertaining companion. Grok-1 utilizes next-token prediction model weights (models that predict the most likely word or symbol to follow a given text sequence) to know how to perform certain tasks.


How was Grok trained?

Like most LLM's today, Grok-1 was pre-trained by xAI on a variety of text data from publicly available sources from the Internet up to Q3 2023 and data sets reviewed and curated by AI Tutors who are human reviewers. Grok-1 has not been pre-trained on X data (including public X posts). Grok’s training journey is outlined on the xAI website and Model Card.


How does Grok use data?

Provide Answers

In responding to user queries, Grok has a unique feature that allows it to decide whether or not to search X public posts and conduct a real-time web search on the Internet. Grok’s access to real-time public X posts allows Grok to respond to user queries with up-to-date information and insights on a wide range of topics.



To continuously improve your experience, we may utilize your X posts as well as your user interactions, inputs and results with Grok for training and fine-tuning purposes. This also means that when you interact with Grok, your interactions, inputs and results may be used to train and enhance the system’s performance. This allows us to:

  • Enhance Grok's understanding of human language and communication.

  • Improve Grok's ability to provide accurate, relevant, and engaging responses.

  • Develop Grok's sense of humor and wit to make interactions more enjoyable.

  • Ensure Grok remains politically unbiased and provides balanced answers.

X users have the ability to control when they want their posts as well as their interactions, inputs and results with Grok to be used for training and fine-tuning purposes, as described below. Please note that you additionally may also prevent your posts from being used for training Grok by making your account private.
