Grok 4 is now free for all users, but with a catch: Elon Musk says ‘The free tier is…’

Elon Musk owned xAI has expanded its latest AI model – Grok 4 to all users. The tech billionaire shared a post on X (formerly Twitter) to announce the same. “Grok 4 is now free for all users,” Musk writes in the post. However, the free access comes with a catch. As revealed by Elon Musk, “The free tier allows a small number of queries per day. Beyond that requires subscription.” Also, the free access is available only for a limited time.


xAI has also shared a post making the announcement about free Grok 4 access. Here’s what it said:


“Grok 4 is now free for all users worldwide!
Simply use Auto mode, and Grok will route complex queries to Grok 4. Prefer control? Choose "Expert" anytime to always use Grok 4.
For a limited time, we are rolling out generous usage limits so you can explore Grok 4’s full potential.”

xAI launches Grok 4

To recall, Grok 4 was launched last month. Grok 4 is designed for those who want a chatbot that can go beyond answering basic questions and instead handle complex topics and ideas.


Grok 4 is available as a part of a new premium offering on X. It can be purchased under a $300 per month “Pro” subscription, which gives users access to its most advanced features.

What Elon Musk said about Grok 4

Speaking during the livestream, the tech billionaire said that “Grok 4 is postgraduate, like PhD level, in everything. Better than PhD — no exceptions”. Acknowledging that while the AI might occasionally miss some common-sense cues, its understanding of academic topics is unmatched. “Most PhDs would fail where Grok 4 would pass,” Musk claimed.


He also shared an X post where he wrote:


“You can cut & paste your entire source code file into the query entry box on http://grok.com and @Grok 4 will fix it for you! This is what everyone @xAI does. Works better than Cursor.”
