What Is Grok AI? Everything You Need to Know in 2025

Grok AI is a chatbot built by xAI, an AI company started by Elon Musk. It works like a smart assistant that helps people ask questions, explore topics, and get real-time information. In 2025, xAI launched Grok 3, its most powerful version yet. This article explains what Grok AI does, how it works, and how it compares to other popular AI tools like ChatGPT and Gemini.

Who Created Grok AI?

Grok AI is made by xAI, an artificial intelligence company launched by Elon Musk in 2023. The company’s goal is to build AI that is helpful, honest, and curious. xAI works closely with Musk’s other companies, especially X (formerly Twitter), where Grok is directly available to users.

Grok AI can perform many tasks. It helps with research, answers questions, summarizes news, explains code, and even makes jokes. Unlike many other chatbots, it pulls real-time data from X and the internet using a tool called DeepSearch.

Grok 3 Brings Major Updates

In February 2025, xAI released Grok 3, which has been trained on 20 times more compute than Grok 1. It now competes directly with leading AI models like GPT-4 and Gemini 1.5.
 

Top Features of Grok 3

1. Think Mode

This mode lets Grok take extra time to give more thoughtful and detailed answers. It's helpful for complex questions like logic puzzles, coding problems, or technical subjects.

2. DeepSearch

Grok 3 can search and summarize live content from the web, including articles, websites, and posts on X. This gives users quick answers based on up-to-date information.

3. Increased Image Generation

Grok supports image generation using AI. Users with SuperGrok plans get more image generation credits.

4. Real-Time Access to X

Grok is deeply connected to X. It can understand trends, hashtags, and user posts in real-time. This makes it useful for social media users and marketers.

5. Casual and Fun Tone

Grok often answers with a light, humorous style. Elon Musk wanted it to be “witty and rebellious,” which makes it stand out from more formal AI tools.

How Do You Access Grok AI?

You can use Grok directly inside X (Twitter). It is available through a subscription called Premium+, which costs around $16/month or $168/year. Grok is also included in the new SuperGrok plan with extra features like higher rate limits and more image generation.

What Is SuperGrok?

SuperGrok is an upgraded plan that offers:

• More Grok 3 requests per day
• Full access to Think Mode and DeepSearch
• Increased image generation

Limitations of Grok AI

While Grok 3 is powerful, it has some limits:

• It may not always work outside of X
• It doesn’t yet support file uploads like PDFs
• No plugin or third-party tool integrations (yet)
• Some features are locked behind a paywall
