On August 11, xAI made an announcement on Platform X that its advanced language model, Grok4, would now be accessible to all users free of charge. However, this free access is capped at a limited number of queries per day, with additional queries requiring a subscription. Prior to this change, Grok4 subscriptions ranged from $30 to $300 per month. This shift to offering a free tier has sparked discontent among existing paid users, who have deemed it a "subscription betrayal." xAI's strategy may be aimed at broadening its user base and gathering data to gain a competitive edge in the AI landscape.
