xAI has made its advanced AI model, Grok 4, accessible to all users, including those on its free tier. Released last month, Grok 4 was initially exclusive to paid subscribers. Now, free users can utilize its Auto and Expert modes. However, the Heavy mode remains exclusive to SuperGrok Heavy users.
This expansion closely follows OpenAI’s release of its GPT-5 AI model to all registered users. The move signifies a competitive landscape in AI development, with both companies striving to democratize access to powerful AI tools. By offering Grok 4’s core functionalities to a wider audience, xAI aims to expand its user base and potentially gather valuable data for further model improvements. The announcement was made via a post on X.
