xAI Rolls Out Grok 4 to All Users
xAI has expanded access to its new artificial intelligence model, Grok 4, offering it to all users. The deployment signifies a notable extension from the model’s original launch last month, which was limited to paying users on the company's SuperGrok and X Premium subscriptions.
The firm declared the advancement on X, mentioning that the growth is applicable worldwide. For a short time, users of the free tier will receive what xAI referred to as “generous usage limits” to test its latest large language model. The action follows closely behind Elon Musk, owner of xAI, releasing the Grok Imagine video generation tool for free to all users in the US, and merely three days after OpenAI granted access to its GPT-5 model for every registered user.
For users who aren't enrolled in xAI's premium plans, Grok 4 will provide two options: Auto and Expert. Auto mode automatically assesses if a prompt needs a greater reasoning budget for a thorough response, or if a quicker, less resource-demanding mode is adequate. In expert mode, users have the ability to manually activate reasoning mode when they find the default output lacking.

Access to Grok 4 Heavy, the company's most advanced version, will still be restricted to SuperGrok Heavy subscribers. Similarly, Grok Imagine, capable of producing images and videos, will continue to be inaccessible to free-tier users outside of the United States. Paid subscribers will keep enjoying increased request limits for all features.
The announcement arrives alongside xAI’s plans to incorporate advertisements directly into Grok’s interface. In a recent discussion on Spaces, Musk mentioned that advertisements might be included in responses and recommendations on both the app and website.

He stated that extra sources of income were needed to fund the cost of the “costly” GPUs that drive the chatbot. Nevertheless, he did not indicate if ads would be distinctly labeled as such.
