Grok 4 is now available to free tier users

xAI has expanded its Grok 4 artificial intelligence model to all global users, regardless of subscription status, as of Sunday. This initiative provides broader access to the AI model, which was initially released last month. The Grok 4 model, previously exclusive to paid subscribers, is now accessible to individuals utilizing the free tier of the platform. This expansion permits free tier users to engage with Grok 4's Auto and Expert modes. The Auto mode automatically assesses prompts to determine whether additional processing is required for a more accurate or detailed response, or if a faster, default response is sufficient. The Expert mode grants users manual control, allowing them to activate a more intensive reasoning mode when they perceive Grok's initial response as insufficient. Grok 4 Heavy, the most performant model within the Grok 4 family, remains exclusively available to SuperGrok Heavy subscribers. Furthermore, Grok Imagine's image and video generation capabilities are not accessible to users outside the United States. xAI's decision to expand access to Grok 4 follows OpenAI's release of its GPT-5 AI model to all registered users just days prior. The official xAI account on X announced the global availability of Grok 4, emphasizing that free tier users would receive "generous usage limits" for a limited duration to explore the large language model. This announcement occurred three days after Elon Musk, owner of xAI, made the Grok Imagine video generation feature available to all US users without charge. Paid subscribers will continue to benefit from higher rate limits across all Grok models and features. Last week, Elon Musk discussed plans during a Spaces discussion to integrate advertisements within Grok's interface, encompassing both its website and mobile applications. This move aims to establish a new revenue stream for the chatbot, which currently generates income primarily through subscriptions and application programming interfaces. Musk cited the necessity of funds to cover the operational costs associated with the "expensive" GPUs that power Grok.

So far, the AI model has only been available to paid subscribers xAI expanded the company's latest artificial intelligence (AI) model, Grok 4, to all users on Sunday. The model, released last month, was previously only available to paid subscribers. With this expansion, those on the free tier will be able to use Grok 4's Auto and Expert mode, while Heavy continues to be exclusive to the SuperGrok Heavy users. Interestingly, xAI's expansion comes just days after OpenAI released its GPT-5 AI model to all registered users. In a post on X (formerly known as Twitter), the official handle of xAI announced that Grok 4 is now available to all users globally. The AI firm also highlighted that for a limited period, those on the free tier will get "generous usage limits" to explore the company's latest large language model (LLM). Notably, the announcement came just three days after xAI owner Elon Musk made the Grok Imagine video generation feature available to all US users for free. Users on the free tier can access Grok 4's Auto and Expert modes What will be available to those who have not subscribed to either SuperGrok or X Premium plans? xAI is offering Grok 4's Auto and Expert modes. Auto mode is a smart mode that automatically determines whether the requested prompt requires an additional reasoning budget to generate a more accurate and elaborate response, or if the fast mode is sufficient. The Expert mode gives users manual control to switch to reasoning mode when they feel Grok's default response is inadequate. However, free users will not have access to Grok 4 Heavy, the most performant model in the AI model's family. Additionally, unless users reside in the US, they will also not have access to Grok Imagine's image and video generation capabilities. Paid subscribers will also continue to get higher rate limits across all the models and features. Last week, Musk shared plans in a Spaces discussion to show ads within Grok's interface, across the website and mobile apps. Currently, apart from subscriptions and application programming interfaces (APIs), there is no revenue stream for the chatbot, and ad integration creates a new avenue for the company. The billionaire entrepreneur said funds were needed to pay for the "expensive" GPUs that power Grok. Based on what Musk said, ads will be integrated within Grok's answers and suggestions. He did not explain whether these ads will be displayed with visible labels to inform users or not.
