What is Grok chatbot and how does it work?

You might’ve heard of Grok, X’s answer to OpenAI’s ChatGPT. It’s a chatbot and, in that sense, behaves as you’d expect — answering questions about current events, pop culture and so on. But unlike other chatbots, Grok has “a bit of wit,” as X owner Elon Musk puts it, and “a rebellious streak.”

Long story short, Grok is willing to speak to topics that are usually off-limits to other chatbots, like polarizing political theories and conspiracies. And it’ll use less-than-polite language while doing so — for example, responding to the question “When is it appropriate to listen to Christmas music?” with “Whenever the hell you want.”

But ostensibly, Grok’s biggest selling point is its ability to access real-time X data — an ability no other chatbots have, thanks to X’s decision to gatekeep that data. Ask it “What’s happening in AI today?” and Grok will piece together a response from very recent headlines, while ChatGPT will provide only vague answers that reflect the limits of its training data (and filters on its web access). Earlier this week, Musk pledged that he would open source Grok, without revealing precisely what that meant.

How does Grok work?

Grok is the invention of xAI, Elon Musk’s AI startup — a company reportedly in the process of raising billions in venture capital.

Underpinning Grok is a generative AI model called Grok-1, developed over the course of months on a cluster of “tens of thousands” of GPUs (according to an xAI blog post). To train it, xAI sourced data from the web (dated up to Q3 2023) and from feedback from human assistants that xAI refers to as “AI tutors.”

Grok-1 is about as capable as Meta’s open source Llama 2chatbot model and surpasses OpenAI’s GPT-3.5, xAI claims.
