Elon Musk-owned xAI made Grok 4 freely accessible to all users worldwide this month, in an attempt to compete with rival platforms OpenAI’s GPT-5.
However, the company said that access to Grok 4 Heavy, its most advanced model, remains exclusive to SuperGrok Heavy subscribers.
Grok 4 features a dual system: Auto Mode and Expert Mode. In Auto Mode, the AI automatically decides if a user prompt requires deeper reasoning or a simple response. Expert Mode allows users to manually trigger a more in-depth answer if the initial response isn’t satisfactory.
In addition to Grok 4, xAI also rolled out Grok Imagine, a free AI video generation tool, with a limited number of queries and currently available only in the United States.
However, it presents challenges such as AI misuse. In this regard, the BBC highlighted Grok 4 misuse in creating explicit deepfake videos of celebrities like Taylor Swift and Sydney Sweeney, raising concerns about content moderation and responsible AI use.
Grok 4 is now free for all users.
The free tier allows a small number of queries per day. Beyond that requires subscription. https://t.co/mdtpamAQ3p
