San Francisco, August 12, 2025 – In a surprising announcement that has sent ripples through the AI community, xAI, the artificial intelligence company founded by Elon Musk, has made its latest model, Grok 4, available for free to all users worldwide.
The move, revealed over the weekend, comes amid intensifying competition in the generative AI space, particularly following recent advancements from rivals like OpenAI’s GPT-5.
The decision was first shared via xAI’s official X account on August 10, stating: “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.” The post emphasized that for a limited time, generous usage limits are being rolled out to allow users to explore the model’s full potential.

Elon Musk, who also serves as CEO of xAI, amplified the news on his X profile the following day, clarifying the details for the free tier. “Grok 4 is now free for all users,” Musk posted. “The free tier allows a small number of queries per day. Beyond that requires subscription.”
This hybrid approach aims to democratize access to advanced AI while maintaining premium options for heavier users. Grok 4, touted as “the world’s smartest AI,” represents a significant upgrade from its predecessors, with enhanced capabilities in reasoning, creativity, and handling complex tasks.
Previously restricted to SuperGrok and Premium+ subscribers, the model is now accessible via the Grok app, x.com, and other platforms without an upfront cost – though with daily query caps to manage server loads and prevent abuse.
Industry analysts see this as a strategic play by xAI to boost user adoption and gather more data for future improvements, especially as OpenAI faces backlash over its GPT-5 rollout.

“By offering limited free access, xAI is positioning Grok 4 as a more inclusive alternative, potentially drawing users away from paid-only models,” said AI expert Dr. Lena Voss in a recent interview.
Alongside the free access rollout, xAI has introduced enhancements like Grok Imagine, an AI image-to-video generation tool, also made available to non-paying users.
However, for unlimited queries and access to even more powerful variants like Grok 4 Heavy, users are encouraged to upgrade to SuperGrok or the newly launched SuperGrok Heavy tier.

The announcement has sparked enthusiastic reactions online, with Reddit threads and tech forums buzzing about the opportunity to test Grok 4 without barriers.
“This could change the game for casual AI users,” one commenter noted on r/LocalLLaMA.
Yet, questions remain about the duration of the “limited time” promotion and exact query limits, which xAI has yet to fully disclose.
xAI’s move aligns with Musk’s vision of accelerating the understanding of the universe through accessible AI.
