The AI race just got more interesting. xAI, Elon Musk’s artificial intelligence company, has surprised the tech world by making Grok 4—its most advanced AI model—free for all users. Until now, Grok 4 was exclusive to SuperGrok and X Premium subscribers, but this sudden policy shift is opening the door for millions to test its capabilities.
However, “free” doesn’t mean without restrictions. xAI has set daily usage limits, and certain premium features remain locked behind paid subscriptions. Here’s a complete guide to accessing Grok 4 for free, understanding its limitations, and exploring what’s next for the platform.

How to Access Grok 4 for Free
Anyone can now try Grok 4 without a subscription via:
- The X mobile app
- The dedicated Grok app
- The web interface at grok.com or directly through the X platform
To ensure you’re always using Grok 4, enable Expert Mode in the AI’s settings. This forces Grok to respond using the most advanced model available instead of switching to a lighter version for performance optimization.

If you keep Automatic Mode enabled, Grok will choose the best model for your request—switching to Grok 4 only when it determines a more advanced response is needed.
Usage Limits for Free Users
While Grok 4 is now accessible to everyone, usage isn’t unlimited. Free-tier users can only make a limited number of queries per day.
Although xAI hasn’t released exact figures, users have reported that the current cap is 10 requests every two hours, resetting automatically. To qualify, your account must:
- Be at least 7 days old
- Be verified with a phone number
Premium features such as Grok 4 Heavy (the most powerful variant), priority response times, and access to experimental tools are still exclusive to SuperGrok subscribers.
Grok Imagine — AI Video Generation for Free (With a Catch)
Alongside Grok 4’s free rollout, xAI has partially opened Grok Imagine, its AI-powered video generator. This tool lets you create short videos from simple text descriptions.
For now, Grok Imagine is:
- Free for a limited time
- Available only in the United States
- Feature-limited for non-paying users
No official word has been given on when or if this feature will roll out internationally.
Why xAI Is Doing This Now
This move is more than just generosity—it’s strategy. With OpenAI’s GPT-5 making headlines and competition among AI providers heating up, xAI’s decision to open Grok 4 to the public is a bold attempt to:
- Attract new users
- Showcase Grok’s capabilities
- Gather valuable feedback for improvements
- Encourage free users to eventually upgrade to paid plans
Elon Musk has also hinted that Grok 5 is already in development and could launch by the end of the year, promising even more advancements in AI.
Final Thoughts
By making Grok 4 free, xAI is giving millions a taste of its most advanced AI technology while building anticipation for what’s next. Yes, there are limits—but this is a golden opportunity for users to experience cutting-edge AI without opening their wallets.
Whether you’re an AI enthusiast, a casual user, or just curious about how Grok stacks up against GPT-5, now is the perfect time to give it a try. With Grok 5 on the horizon, the AI battle in 2025 is only just beginning.
