    "Authorization": "Bearer YOUR_XAI_API_KEY",
    "Content-Type": "application/json"
}

payload = {
    "model": "grok-4-mini",
    "messages": [
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Explain quantum computing in simple terms."}
    ],
    "temperature": 0.7
}

response = requests.post(url, headers=headers, json=payload)
print(response.json()["choices"][0]["message"]["content"])

The free API tier includes:

$25 in free credits per month for new accounts
Access to grok-4-mini and limited grok-4 usage

Step 2: Tap the Grok icon (typically at the bottom navigation bar or accessible via the compose screen).

Step 3: Chat directly with Grok 4. The mobile interface also supports voice input, making it convenient for hands-free usage.

Tips to Maximize Your Free Grok 4 Usage

1. Batch Your Questions

Rather than sending multiple short messages, combine related questions into a single, detailed prompt. This conserves your daily message limit.

Instead of sending 5 separate messages, try:

"I have three questions about Python:
1. What is the difference between a list and a tuple?
2. How do I handle exceptions properly?
3. What are the best practices for virtual environments?
Please answer each with a code example."

2. Use Grok 4 Mini for Simple Tasks

Reserve your limited Grok 4 full messages for complex reasoning tasks. Use Grok 4 mini (which has a higher free limit) for straightforward questions, writing assistance, and simple coding tasks.

3. Leverage Real-Time Search

One of Grok's unique advantages is real-time access to X posts and web data. Use this for current events, trending topics, and recent developments that other models may not have:

What are developers saying about the latest React 20 release?
Summarize the key reactions from X/Twitter posts in the last 24 hours.

4. Enable Think Mode for Complex Problems

When tackling hard problems (math, logic, multi-step coding), enable "Think" mode. It uses more compute but produces significantly better results on complex tasks. Since you have limited messages, making each one count is important.

5. Time Your Usage

Free tier limits typically reset every 24 hours. If you hit your cap, note the time and plan your most important queries for after the reset.

Common Use Cases for Free Grok 4

Real-time analysis: Monitor trends, summarize breaking news, and analyze social media sentiment using X integration.
Coding assistance: Debug code, generate functions, and explain complex algorithms with the sandbox environment.
Research: Leverage the large context window to analyze lengthy documents and research papers.
Creative writing: Generate stories, marketing copy, and brainstorm ideas with Grok's distinctive personality.
Math and science: Use Think mode for step-by-step solutions to complex mathematical and scientific problems.

Limitations to Keep in Mind

Message caps are strict. Once you hit your daily limit, you must wait for the reset.
No file uploads on free tier. You cannot attach PDFs, images, or other files without a premium subscription.
Image generation quality varies. The free tier DALL-E equivalent (Aurora) produces decent but not premium-quality images.
Rate limiting during peak hours. Free users may experience slower response times when demand is high.
Personality can be opinionated. Grok is intentionally designed with a more casual, sometimes edgy personality compared to other assistants.

Conclusion

Grok 4's free tier offers genuinely useful AI capabilities, especially if you value real-time information and strong reasoning. By being strategic with your daily message allocation and using Grok 4 mini for lighter tasks, you can get substantial value without a subscription.

For creative professionals who need AI-powered media generation alongside their text-based AI workflows, Hypereal AI offers affordable pay-as-you-go pricing for high-quality AI video generation, talking avatars, image creation, and voice cloning -- making it a powerful complement to Grok for when you need to turn ideas into visual content.
