Getting Started

Go to grok.com or download the X (Twitter) app and sign in with your account.

Free users get access to Grok with limited daily messages.

Upgrade to X Premium+ ($16/mo) for full Grok access, higher limits, and image generation with Aurora.

Use Grok on the web at grok.com, in the X app, or through the xAI API for developers.

Key Features

Real-Time X (Twitter) Data

Grok has direct access to posts, trends, and conversations happening on X in real time. Ask about trending topics, public sentiment, or breaking news and get answers grounded in live social data.

Fastest Inference Speed

Grok is roughly 6.5x faster than Claude and significantly faster than GPT-4o at generating responses. For quick questions, brainstorming, and rapid iteration, the speed difference is immediately noticeable.

Aurora Image Generation

Generate photorealistic images with Aurora, Grok's built-in image model. Known for fewer content restrictions than DALL-E, making it more flexible for creative and artistic projects.

Unfiltered Conversations

Grok is designed to tackle questions that other AI models might refuse or hedge on. It gives more direct, less sanitized answers while still being helpful. If you find other models too cautious, Grok may be refreshing.

Strong Reasoning Capabilities

Despite its speed advantage, Grok doesn't sacrifice reasoning quality. It performs well on math, logic, and coding benchmarks, offering a compelling combination of speed and intelligence.

Competitive API Pricing

For developers, the xAI API offers Grok models at some of the lowest per-token prices among major providers. Combined with fast inference, this makes it cost-effective for high-volume applications.

Prompting Tips for Grok

Ask About Current Events

Grok's real-time access to X data makes it excellent for current events and trending topics. Ask about what's happening right now, public reactions, or breaking news.

"What are people saying about [topic] on X right now? Summarize the main viewpoints and any notable posts."

Be Direct

Grok is designed for straightforward communication. You don't need to be overly polite or add disclaimers. Just ask what you want to know directly and you'll get a direct answer.

Instead of: "Could you perhaps help me understand the pros and cons of..."
Try: "Give me the honest pros and cons of using Kubernetes vs serverless for a startup with 3 engineers."

Use Speed for Brainstorming

Grok's fast response time makes it ideal for rapid brainstorming sessions. Fire off quick prompts, get instant responses, and iterate rapidly. The low latency means your creative flow stays uninterrupted.

Leverage the 2M Token Context (API)

If you're using the xAI API, Grok 4 Fast supports up to 2 million tokens of context. This is useful for processing very large codebases, document collections, or long conversation histories programmatically.

Try "Fun Mode"

Grok has a distinctive personality that shows when you engage with it conversationally. Ask for opinions, debate topics, or request explanations with humor. It's more willing to be entertaining than most AI assistants.

"Explain quantum computing but make it funny. I'm a software engineer who's heard the term 1000 times but still doesn't really get it."

Example Prompts

Copy these prompts to try in Grok. Each one is designed to showcase a specific strength.

Current Events

What are the biggest stories trending on X right now? Give me a quick summary of the top 3, including the general sentiment (positive, negative, mixed) and any notable takes.

Why this works: Leverages Grok's unique real-time X data access. No other major AI model has this capability.

Quick Analysis

Compare React, Vue, and Svelte for a new side project in 2026. I want a table with: learning curve, ecosystem size, performance, and job market demand. Be opinionated, not neutral.

Why this works: Direct, opinionated instruction plays to Grok's unfiltered style. Gets a more useful, decisive answer than "it depends."

Coding

Write a TypeScript utility function that debounces API calls with a configurable delay. Include proper typing, cancellation support, and a usage example.

Why this works: Fast inference means you get working code almost instantly. Good for rapid prototyping and utility generation.

Creative

Generate a photorealistic image of a cozy cabin in the mountains during autumn. Golden hour lighting, leaves falling, smoke from the chimney. Hyper-detailed.

Why this works: Aurora image generation with fewer content restrictions than competitors. Specific atmosphere and lighting direction improve results.

Research

I'm considering switching from AWS to Google Cloud for our startup's infrastructure. Give me the brutally honest pros and cons. We use: EC2, S3, Lambda, RDS PostgreSQL, and CloudFront. Budget is $2K/mo.

Why this works: Asking for "brutally honest" analysis gets Grok's direct, unfiltered evaluation rather than a diplomatic both-sides answer.
