xAI Launches Global Access to Grok 4 AI Model with Temporary Boosted Rate Limits
xAI has made a significant move by expanding access to its latest artificial intelligence model, Grok 4, to all users as of Sunday. Previously limited to paid subscribers, Grok 4 now allows free-tier users to utilize its Auto and Expert modes. This expansion comes shortly after OpenAI introduced its GPT-5 model to registered users, marking a competitive moment in the AI landscape. However, the most advanced features remain exclusive to SuperGrok Heavy users.
Grok 4 Now Accessible to Everyone
In an announcement on X, formerly known as Twitter, xAI confirmed that Grok 4 is now available to users worldwide. The company emphasized that free-tier users will enjoy “generous usage limits” for a limited time, enabling them to explore the capabilities of this advanced large language model (LLM). This announcement follows closely on the heels of Elon Musk’s decision to make the Grok Imagine video generation feature available for free to all users in the United States.
For those who have not subscribed to either the SuperGrok or X Premium plans, Grok 4 offers two modes: Auto and Expert. The Auto mode intelligently assesses whether a prompt requires additional reasoning for a more detailed response or if a quicker answer suffices. Meanwhile, the Expert mode allows users to manually switch to reasoning mode if they find Grok’s default response lacking. However, it is important to note that free users will not have access to Grok 4 Heavy, the most powerful model in the Grok family.
Limitations for Free Users
While free-tier users can access Grok 4’s Auto and Expert modes, they will miss out on the capabilities of Grok 4 Heavy. This model is designed for optimal performance and is reserved for SuperGrok Heavy subscribers. Additionally, users outside the United States will not have access to Grok Imagine’s image and video generation features. Paid subscribers will continue to benefit from higher rate limits across all models and features, ensuring they have a more robust experience with the AI.
The recent changes highlight xAI’s strategy to broaden its user base while maintaining premium offerings for paying customers. As the competition in the AI sector intensifies, these adjustments may help xAI attract more users and enhance engagement with its technology.
Future Revenue Streams and Advertising Plans
In a recent discussion, Elon Musk revealed plans to introduce advertisements within Grok’s interface, both on the website and mobile applications. Currently, xAI relies on subscriptions and application programming interfaces (APIs) as its primary revenue sources. The integration of ads could provide a new financial avenue for the company, which Musk noted is necessary to cover the high costs associated with the GPUs that power Grok.
Musk indicated that the ads would be incorporated into Grok’s responses and suggestions, although he did not clarify whether these advertisements would be clearly labeled for users. This move could potentially change the user experience, as it introduces a commercial element to the AI’s interactions. As xAI continues to evolve, the balance between user experience and revenue generation will be crucial in shaping its future.
